The company I work for specialize in portable machining. We do have this same machine, just one size smaller. It performed about as expected. When close to the center, you could probably have been a bit more aggressive with your cuts. You were missing the counterweight, I don't know that it would have helped, the design on the MMi machines is not the best, it can act like a tiningfork sometimes. But you would at least have more consistent speed. A trick that can sometimes help is to put a lifting-magnet on the cantelevered arm. This can help absorb vibrations sometimes. I also know some of our guys swear by 0.2 radius inserts for difficult conditions like this. If you could get a hold of an OD mount (ring) machine, that would be much better. Then you don't have the cantelever to deal with, and the feet are much easier to adjust. Just make sure to not overtighten them as you will turn the ring into a square 😅. There is also a significant difference in quality from model to model. Some are stable enough to break a chip just like normal lathe. The heavier, the better usually, except when you need to get into akward spaces, which seems to be the case about half the time 😂. There are also milling-macines, both orbital types, similar to this macine, and cartesian machines, even CNC-controlled ones that could also be used here.
Yeah, I do this kind of work for 20 years and your advice is spot on. Mirage machines are a bit too "jumpy" because of their center motor construction. I prefer Silk almost every time. And yes, 0.2 IS the way to go and whenever an OD machine is possible, go with it. Nice to see others in this tiny specialized field almost no one ever hears about.

After 53 years as a fitter / turner in Toowoomba QLD it's still good to see HSS has it's place, it cuts, does not rely on pressure like carbide, it also handles vibration where as carbide chips as you found out. What a great facing machine, having this tool will attract more work like this.

Great content - looks like I'm one of the few Aussies here ! Amazing how many commenters referenced CEE or even just Kurtis and that was enough. Of course CEE's not so secret weapon is Karen who pulls the whole thing together but you have your own unique presentation and happily have a very personable demeanor.

Chater the bane of any machinist. Interested to see how you will recut the six o-ring grooves. Absolutely love how you show the struggles and how you overcome them keep it up!!
Id imagine you could get a hole-saw of the correct size, make a plug that the bit can fit in and keep it centered, and then go for it. Have to make the saw though
Always ...always ...always plan for warp when building weldments. If you get lucky and the warp is within spec, run with it. When the plates get thicker the weld gets larger, the contraction forces during cooling increase immensely. If you can't take the part to the precision, take the precision to the part. This type of flange work is critical in some pipe work when high pressures are involved. Always great to see someone learn a new process and put that skill in their toolbox.
Really enjoying your content from here in San Antonio.Texas. Hard to believe, but at 78 years of age, I'm actually learning the metric system. Thanks much.
Hey Matt you've taken me to 1993, Sarnia, Ontario. A CN railroad tunnel under the St Clair River the internal diameter to carry double stacker containers on rail road low boys carriages. Without digging my CV can't tell exact diameters. The Tunnel Boring Machine (TBM) is a Lovatt built in Mississauga near Toronto Ont. The closest tunnel their machines have worked to home ever. The barrel of the machine was articulated for steering purposes and contamination was noticed in the bearings lube oil. The tunnel had advance under the Exxon world oil test center which had to be jacked up and anti vibration pads fitted plus none settlement piles inserted. The river was 100m ahead so not a good spot to stop, an area of land was rented and a shaft consolidated in poor ground by hollow piling and filling with light bond concrete on withdrawal. The head of the TBM then driven into the solid shaft which was then excavated. The head was removed and just like your problem there was wear on high spots. The head was cut in two and sent back the works. But the out edge of the casing head to be machine and along came a giant version of you machine, we had ship yard inspectors fly out from the UK to oversea this works. The were amazed how quickly and effectively Lovatt's machinist set up and skimmed that out face. The head arrived back in one piece by CN rail, installed and the TBM headed off under the ST Clair River and completed the tunnel with clear lube oil. The tunnel was a Brit design hence why was there on works inspection duty. On breakthrough into Michigan US. I followed the tunnel crew clambering through the head and into the US. After photos and speaches we went to climb back through, but were stopped by the US safety dept. A crew bus was laid on to transport us over the border bridge to Canada. The local crew had border passes, my UK passport was in the top drawer of my bedroom in a river front apartment that could be seen from the bridge. At US Immigration the lads showed their cards the guard held his hand out for mine and I told him where it was. He then asked how the hell I got into the US. all the lads in unison called out. " We dug a tunnel" What's better it was repeated on the Canadian side. Thanks for taking me back and stirring old memories in my 79th year of retirement.
Detroit, Michigan, General Motors Experimental Engineering, [Retired] Now I own a Hobby machine shop, just for fun. Kurtis at CCE, and you are my fav chnls
Have not missed a single video from Kurtis and Karen since they launched CEE, and now so happy to have stumbled in here. Watching from central Canada. Happy Holidays!
My first video and it won't be the last. I am impressed.My home is Memphis, Tennessee in the United States of America. I had a hobby machine shop but when I retired I quit; alas no room for the lathe in the retirement villiage. This is the first channel that I have watched that dealt with such large pieces to be machined. I look forward to more episodes.
It don't matter what situation you find yourself in, odds on someone somewhere has been there before you. That means that there is a good chance the right tool already exists to fix your situation, you just need to find it. Thanks to Phil, it would appear you found the right tool for this particular job.
Great episode,100% quality H.S.S. is the way to go ,and is very underestimated by younger tradesmen. Many tradesmen haven't the skills to grind H.H.S tools today. Personally, where I did my Fitting & Turning apprenticeship in Australia, we machined different steels, especially stainless steel, the first 2 years the apprentices had to use H.H.S. hand ground carbide years 3 & 4. We used Assab 17 H.H.S, and after hand grinding, the tools were oil stoned. Always using sulphur based cutting oil. I still always use H.H.S when screw cutting . Keep up the great work.
Watching from Las Vegas, Nevada USA. Cutting Edge Engineering led me to this. I'm enjoying accumulating a layman's knowledge of machining. Happy Holidays, everyone! 😀❤👍
Glad to see that Kurtis finally got that Franna going there in the opening segment ;) When I'm not watching youtube videos I'm making Christmas light controllers (mostly). Today is 22nd of August and I'm currently sending out 5 deliveries on Monday. I fully expected to be dead quiet this close to Christmas. Merry Christmas to Matt, Morgan and the rest of the HAL crew. Look forward to seeing the website up and going in the new year as all electronics techs several states away from FNQ are interested in heavy duty machining for the mining industry ;)
Thanks for the trip to now what. As an 80 year old machinist / mechanic/ welder I learned from the old guys now known as old school is that the impossible just takes a little longer and for the foreman that comes in every 1/2 hr wanting to know when its going to be done, I would say when the last bolt is tight and not one minute before. It's the challenge that makes the job not the easy part. Hang in their and keep the vids comming. Paul from Oregon
8:33 It's absolutely lovely how that thing Starts cutting. I know line boring but that's new to me thanks Matt. In our workshop we would face mill that and rework all holes in the next steps so everything is in line and running together good as needed. This video was really nice to watch ❤ Greetings
Do a post weld heat treatment of the welded areas on the flange at about 580 to 600 Deg C for an hour per inch and cool in still air, that should do two things; temper the hard areas around the weld, and relieve stress so that after machining the flange remains dimensionally stable er.
@@leso204 You might be able to use local electric heating elements under insulation over the flange face quite successfully. Can extend the top temp to 620 Deg C if maintaining a stable temp is tricky for the controller... Try talking with your local NDT Lab, they should have the gear & the knowledge... If that is cost prohibitive you can flame it manually, but you need to control that top temp for at least 15 - 20 mins to see a result. A portable hardness tester is your friend, it will tell you how effective the stress relief has been - measure at ambient. If you contact the steel maker and ask their advice about max permitted tempering temp you might be able to go higher which will certainly help further, 620 Deg C should be safe but depending on what the steel maker says you might be able to go to 650Deg C or even slightly higher if you really need to. The amount of stress relief is more dependent on max temp than time at temp.
@@leso204nope large vessels can be stress relieved and commonly are with portable ceramic/resistance heater blankets. It takes quite a bit of setup but is required when making large carbon steel weldments. Plus induction heating would be localized.
You have a lot of humility for a shop that has a lot of capacity and capability. I have a hobby shop with a 16" American Pacemaker. Your work dwarfs my capacity!
Cheers mate. I’m pretty grateful to get to do the work in all honesty. I find machining very relaxing and challenging at the same time. Never a dull moment when I’m spinning big stuff 👊
This is my world. Portable tooling and onsite machining for the win. The challenges of how the F#$% are we gonna do this and then setting it up is where the fun is at. Rigidity is the bugaboo with cantilever style machines overcoming it can be the biggest challenge. looks like you rose to that challenge and managed to win. Thank the gods for ingenious men who make portable tools and the tool rental companies that have this stuff available for our use is all I can say! Great episode Matt you guys are rocking it...Upside down and warm 😁 -10C or so here this morning where I live Brrrrr from New Hampshire USA.
Problem solvers come in every profession. I solve your problem by making your Sheila look her best for you at my salon. The rest is on you. Happy Wife, happy life yeah?
The flange facer was a clever machine, and you gotta love it, seeing good old HSS cutters to the rescue! Happy Holidays, and hope you folks have a great 2025!
I have to say that You Australlia guys are awesome. CEE and HAL my god what a diamond discovery. Love the content. I'm cnc machinist on small 3 axis mill and im so stunned buy Your's craftsmanship! Amazing!
From California USA; unfortunately I knew it would warp from the welding. It is amazing how much the welding will pull and warp that thick of steel. That stress is still in the steel; but with that light of cuts the warping after the cutting “ I am hoping is not excessive”. Remember that episode at CEE where Curtis had that improperly heat treated steel that kept warping after every cut because of the internal stresses! I would recommend be careful and Do not cut the O-ring groves too deep. Leave enough rubber standing proud of the face so that the O-rings can compress down and seal. With the amount of torque that thing is going to have on it might cause it to start walking around on those bolts and possibly even loosen the bolts. This is so interesting. I am definitely not going to miss this.
Cheers mate! Yeah it’s an odd work piece to machine hey. We’ve still got the O rings to do in the new year… and I’ll be doing them at the absolute minimum depth. For the reasons you just listed. Looks like the MEGADRILL should be finished early Feb… Then, it’s time to SEND IT!
Arizona, US and I think I just found a new favorite machining channel. Thanks for taking the time to explain everything, always good to learn. Merry christmas.
Just subscribed from Salt Lake City, Utah. It’s been mentioned before but you’re turning into another CEEAUS which i mean as a huge compliment. The work you do is fascinating but the videos are a success because you include personal bits with your family and mistakes you’ve made. Your humbleness makes you relatable. Congratulations on your growing success.
machinist in Florida. USA. Been at it for 35 yrs. Ive done big work in foundry settings. I know what you are dealing with. Its a challenge but sure is fun to do. Enjoyed seeing your solution to the problem, not seen a face bore before. Very cool to watch.
That's a great piece of equipment for that particular type of job. I wish America would take a holiday. Many of us have to work every day except for Christmas itself. You remind me of, Kirtis. You're both smart and hard-working men. Hopefully, you have a wonderful Christmas break.
might be a good idea to talk to someone in the gold mining industry. they use those flange facing machines on the autoclave flange faces. the face is overlaid with titanium then machined to achieve a "gramophone" finish so that the chevron spiral wound gaskets willl seat properly. never actually done the job myself, had others who did the machining for us, but it is a very interesting process on a flange that is approx 1500mm diameter.
I'm watching from northern Illinois, USA, northwest of Chicago. I love your content, narration and videography (Karen would be proud). Have a Merry Christmas and Happy New Year! You guys deserve a nice break from your hard work.
This is coming from a Field Machinist running the same types of equipment almost everyday. In this instance I would have gone for an OD mounted machine just for the sake of rigidity and faster material removal. ID Mounted machines are great for certain things but in this case with the heat affected area and many interrupted cuts it wasn’t the best machine to use.
@@nrml76 guessing, very long heavy straight axle thru the hole, 2 mounting points in the bore, cutter is centered on the axle, or laser and a very fine hole in the cutter, maybe even do multiple lasers.
Hi Matt I suspect a mill would work better for facing the interrupted cut, not sure whats out there these days. There are contractors in the area that do nothing but machine stuff in place for paper mills etc. If you get bored troll the Climax machine too website. HSS has saved many projects for me this summer facing big flanges full of holes. I would go with a cobalt HSS or even Stellite tools because they will last longer. Funny there is nothing like a Frenna or wobbly crane in here in the US. We just use forklifts of all sizes. Hope you have a wonderful Christmas! Ross
great comment - also, Franas are an aussie invention!! They also tip over a lot, not because they suck - sometimfes because in the wrong hands, sometimes because moving under load on construction sites = potholes/uneven ground, holes under surface so then an otherwise pretty static load becomes very dynamic, very quickly, and when moving you aint on outriggers! on even ground and in the right hands they are phenomenal for a lot of jobs and the later models are heaps improved, huge wide wheel base, many axels and can lift a bunch of weight and go for a little drive plus sneak into all sorts of tight areas, especially with the articualtion at the centre and a compact size vs lifting capacity - but still a very risky thing in the hands of a person that doesn't understand the implications/hazard potentials when dynamic loads are at play. Pretty sure some new ones have outriggers too anyway. Anyway - Kurtis at CEE engineering - another Aussie Machinist/metal worker from aus on YT has a whole series of videos doing a complete teardown/rebuild/resto on a 30 yr old Franna that's absoultely awesome content from a guy with loads of brilliant vids - an absolutely top notch, multiskilled/creative fella that many commenters on this vid love watching too i see
Matt ,yall are the problem solving masters ,...I enjoy your vids from far western Kentucky usa,...I just wanted to mention a trick i learned from a buddy ,...use it or throw it away ,...when moving an object with the truck crane we found old truck tires useful bunjeed or wratchet strapped to the bumper so the oblect being moved does not damage itself or the crane while bein transported,... sometimes multiple tires are used ,....great holidaze , MERRY CHRISTMAS and a helluva boxing day,...Mike
centre of gavity is further back though, that's why the crane is so long - sure you use commons sense/experience though and get by well enough - but worth metioning for anyone that takes that advice without consideration of implications for load chart related matters - especially if movement under load is a factor - where dynamic loads introduce all sorts of compounded factors - worst of all in that case - deflection/cavities under surface or any number of smaller but compouding factors. that's why contolling the controllable and working below maximums isn't just good practice, it should always be front an centre in setting up for success
I love seeing new stuff like this pass across my feed. Im sure the algorithm led me here from how much i watch Curtis of CCEA. And im watching from Cemtral Florida in the US. Gonna be checking more of your stuff out for sure.
I might have tried a brazed carbide tool. Tougher than an insert, stays sharp longer than HSS. Or even a solid carbide tool for the same reasons. Of course the heat affected zone could be avoided or minimized by welding in smaller sections or heating the whole thing before welding. But that may just make it worse. May want to consider your order of operations, weld then heat the flange up and allow it to normalize, then weld to the larger part. At least then there would be consistency even if that means consistently wrong. Can see Curtis now furiously planning out a shop built flange facer.
I think it would be incredibly interesting to see a video of a project they failed to fix. It's okay to admit something beat you. Then you get to ask for help from the community and learn new techniques like the one in the video!
They sell carbide inserts with not only different coatings but different carbide grades, using a different mixture of carbide and cobalt. The more cobalt the tougher it is, the more carbide the harder it is. Finding the right insert is difficult, since every manufacturer has a different grading system. That’s where a sales rep can point to the best grade for the application. A large radius provides a better finish in rigid environments but produces more force and will tend to bounce in less rigid environments. A small radius will cut with less force and be more stable in worse conditions. That is an interesting project. Good job on working through it.
First time here from UK, came from CEE. Subscribed and will binge watch previous episodes. Merry Christmas and a Happy New Year to everyone, wherever you are.
matt, think you earned a few beers after that 👍 should think half the battle is working out where the true centre line is, though that does change static or dynamic. never seen a facer before!
Shout out to Phil the Tool guy. I've never seen one of those before! Poor inserts, positive inserts dont like interrupted cuts ( stating the obvious). Good old, but not that old HSS. Immensely enjoyed that job, nice armchair mode, many thanks Matt, excellent engineering 👍. May i wish you, your family, and all at HAL a merry Christmas and safe 2025.
Hi & Merry Christmas from the UK! This is the first time I've viewed your channel & have subscribed to follow the progress of that huge boring head. I'm another great fan of Kurtis at CEE so this content is right up my street!!😊
Dude… that was an education if ever I’ve had one. Never even knew such a bit of kit existed until now. After seeing what was going on with the inserts my brain went to good old hi speed or tungsten. The cutters I learnt on & you went there too so I was a little chuffed over that, & it worked which was wicked cool. As for an easier way??? Sent it to Kurtis 😂 he probably won’t speak to ya ever again but it’s still easier.😂😂😂 My very best wishes to you guys. Hope you all have a very merry Christmas & safe & happy new year. Thanks so much for pitting this channel together. It’s helped me more than you know. Cheers everyone Patch
Thanks for bringing us along , I have done project engineering on five continents and have had to use a flange facer mor than once. You were correct to go to HSS after the first chatter and chip out issue, which by the way is a common issue.
Just found you today. I live in Kilgore, Texas. Been a huge fan of Curtis with Cutting Edge Engineering for a number of years. I am excited to find another Aussie engineering Chanel and really admire excellence.
Hi. Bob Thompson from Winchester, United Kingdom. First time viewer, fascinating for me as a retired engineer. Good luck. Look forward to further posts. Best regards. Bob.
Great job. I’m a retired machinist in Canada eh ! When you started the facing job the first thing that crossed my mind when I saw the o-ring grooves was why aren’t they using HSS. Good stuff.
I'm actually seriously impressed with that machine! With the HSS and the very slow RPM, it was essentially doing the equivalent work of an old school shaper ... with nowhere near the mass and stability! Thanks for sharing 🇨🇦
I have done a little bit of machining in class and out. This machine reminds me of a portable cylinder borer and a portable valve face restoring machine for steam locomotives. Those are two different machines but are set up on the cylinder saddle for boring the cylinders of the piston and piston valve for the borer and a machine that mounts above the valve face of a slide valve-equipped locomotive to reface the slide valve surface to restore the surface for the slide valve to ride on. Both machines are used instead of removing the cylinder saddle to set up on a horizontal or vertical boring machine or mill to do the job, particularly when the machines are not available where the work needs to be done. I thought that adding a bar and support through the hole to the other side of the head would add some rigidity to the machine and set-up if it could be done. This would add a longer shaft for the machine to rotate around and be steadier than just the clamps used gave, I could be wrong because of inexperience. Arp, Texas. In the northeastern part of the state.
Brilliant video and solution to a problem. It always amazes me the range of tools and machines that are out there. Have a brilliant Christmas and a Happy New Year

Chater the bane of any machinist. Interested to see how you will recut the six o-ring grooves. Absolutely love how you show the struggles and how you overcome them keep it up!!
Id imagine you could get a hole-saw of the correct size, make a plug that the bit can fit in and keep it centered, and then go for it. Have to make the saw though
Bolt a Bridgeport to it and bore it.
I reckon if you made a tool up that fits in a mag drill that uses the centre hole for locating it would turn out good enough for an o ring groove
Always ...always ...always plan for warp when building weldments. If you get lucky and the warp is within spec, run with it. When the plates get thicker the weld gets larger, the contraction forces during cooling increase immensely.
If you can't take the part to the precision, take the precision to the part. This type of flange work is critical in some pipe work when high pressures are involved.
Always great to see someone learn a new process and put that skill in their toolbox.
Why put a piece on the lathe when you can put a lathe on the piece.

Really enjoying your content from here in San Antonio.Texas. Hard to believe, but at 78 years of age, I'm actually learning the metric system. Thanks much.
Got to have the room to spin the Shop around the part! Lol
Hey Matt you've taken me to 1993, Sarnia, Ontario. A CN railroad tunnel under the St Clair River the internal diameter to carry double stacker containers on rail road low boys carriages. Without digging my CV can't tell exact diameters. The Tunnel Boring Machine (TBM) is a Lovatt built in Mississauga near Toronto Ont. The closest tunnel their machines have worked to home ever. The barrel of the machine was articulated for steering purposes and contamination was noticed in the bearings lube oil. The tunnel had advance under the Exxon world oil test center which had to be jacked up and anti vibration pads fitted plus none settlement piles inserted. The river was 100m ahead so not a good spot to stop, an area of land was rented and a shaft consolidated in poor ground by hollow piling and filling with light bond concrete on withdrawal. The head of the TBM then driven into the solid shaft which was then excavated. The head was removed and just like your problem there was wear on high spots. The head was cut in two and sent back the works. But the out edge of the casing head to be machine and along came a giant version of you machine, we had ship yard inspectors fly out from the UK to oversea this works. The were amazed how quickly and effectively Lovatt's machinist set up and skimmed that out face. The head arrived back in one piece by CN rail, installed and the TBM headed off under the ST Clair River and completed the tunnel with clear lube oil.
The tunnel was a Brit design hence why was there on works inspection duty. On breakthrough into Michigan US. I followed the tunnel crew clambering through the head and into the US. After photos and speaches we went to climb back through, but were stopped by the US safety dept. A crew bus was laid on to transport us over the border bridge to Canada. The local crew had border passes, my UK passport was in the top drawer of my bedroom in a river front apartment that could be seen from the bridge. At US Immigration the lads showed their cards the guard held his hand out for mine and I told him where it was. He then asked how the hell I got into the US. all the lads in unison called out. " We dug a tunnel" What's better it was repeated on the Canadian side.
Thanks for taking me back and stirring old memories in my 79th year of retirement.
Excellent story. You have a sharp memory. Only times of good times like that can be recalled vividly. Thanks for sharing.
My 80th is coming up in January.
@@timlee4204 Happy Birthday for January, mines in April.
Called on Lovat during the 80s and 90s. They had just started on the machine to do the English Channel tunnel. It was Hugh.
We dug a tunnel 😂😂😂! Great story
Huge fan of Curtis's channel & became a fan of your channel quickly. LOVE it. Cheers from Cape Town, South Africa 🍻🤙😎

Now I own a Hobby machine shop, just for fun.
Kurtis at CCE, and you are my fav chnls
Have not missed a single video from Kurtis and Karen since they launched CEE, and now so happy to have stumbled in here. Watching from central Canada. Happy Holidays!
Cheers good sir. Yeah, their content is solid gold! About as good as it gets as far as machining videos go.
I watch Curtis's Channel many Years , and now I watch Your Channel too!! Awsome !!!! 👍👍👍👍
Greetings from South Germany.
Bernd
Awesome! Thank you!
🇩🇪🙏
and I knew those portable lathes / flansh facers from CEE, too
mechanical engineer from south germany here :D
My first video and it won't be the last. I am impressed.My home is Memphis, Tennessee in the United States of America. I had a hobby machine shop but when I retired I quit; alas no room for the lathe in the retirement villiage. This is the first channel that I have watched that dealt with such large pieces to be machined. I look forward to more episodes.
Cheers good sir! Wishing you a very merry Christmas 🎄🇺🇸👊
It don't matter what situation you find yourself in, odds on someone somewhere has been there before you.
That means that there is a good chance the right tool already exists to fix your situation, you just need to find it.
Thanks to Phil, it would appear you found the right tool for this particular job.
Great episode,100% quality H.S.S. is the way to go ,and is very underestimated by younger tradesmen. Many tradesmen haven't the skills to grind H.H.S tools today. Personally, where I did my Fitting & Turning apprenticeship in Australia, we machined different steels, especially stainless steel, the first 2 years the apprentices had to use H.H.S. hand ground carbide years 3 & 4. We used Assab 17 H.H.S, and after hand grinding, the tools were oil stoned. Always using sulphur based cutting oil. I still always use H.H.S when screw cutting . Keep up the great work.
Watching from Las Vegas, Nevada USA. Cutting Edge Engineering led me to this. I'm enjoying accumulating a layman's knowledge of machining. Happy Holidays, everyone! 😀❤👍
Thanks for watching mate! 🙏🇺🇸
Glad to see that Kurtis finally got that Franna going there in the opening segment ;)
When I'm not watching youtube videos I'm making Christmas light controllers (mostly). Today is 22nd of August and I'm currently sending out 5 deliveries on Monday. I fully expected to be dead quiet this close to Christmas.
Merry Christmas to Matt, Morgan and the rest of the HAL crew. Look forward to seeing the website up and going in the new year as all electronics techs several states away from FNQ are interested in heavy duty machining for the mining industry ;)
Have a fantastic Christmas Alan. And a special thanks for all your support and awesome comments during the year mate. Much appreciated 👊
Thanks for the trip to now what. As an 80 year old machinist / mechanic/ welder I learned from the old guys now known as old school is that the impossible just takes a little longer and for the foreman that comes in every 1/2 hr wanting to know when its going to be done, I would say when the last bolt is tight and not one minute before. It's the challenge that makes the job not the easy part. Hang in their and keep the vids comming. Paul from Oregon
Thanks heaps mate! Appreciate the support. 👊🇺🇸
8:33
It's absolutely lovely how that thing Starts cutting. I know line boring but that's new to me thanks Matt.
In our workshop we would face mill that and rework all holes in the next steps so everything is in line and running together good as needed.
This video was really nice to watch ❤
Greetings
Do a post weld heat treatment of the welded areas on the flange at about 580 to 600 Deg C for an hour per inch and cool in still air, that should do two things; temper the hard areas around the weld, and relieve stress so that after machining the flange remains dimensionally stable er.
that would have to be induction heated on a work piece that large unless you have a furnice to put the whole unit in
Sounds like a good suggestion.
@@leso204Hi wouldn't ceramic heaters suffice?
@@leso204 You might be able to use local electric heating elements under insulation over the flange face quite successfully. Can extend the top temp to 620 Deg C if maintaining a stable temp is tricky for the controller... Try talking with your local NDT Lab, they should have the gear & the knowledge... If that is cost prohibitive you can flame it manually, but you need to control that top temp for at least 15 - 20 mins to see a result. A portable hardness tester is your friend, it will tell you how effective the stress relief has been - measure at ambient. If you contact the steel maker and ask their advice about max permitted tempering temp you might be able to go higher which will certainly help further, 620 Deg C should be safe but depending on what the steel maker says you might be able to go to 650Deg C or even slightly higher if you really need to. The amount of stress relief is more dependent on max temp than time at temp.
@@leso204nope large vessels can be stress relieved and commonly are with portable ceramic/resistance heater blankets. It takes quite a bit of setup but is required when making large carbon steel weldments. Plus induction heating would be localized.
You have a lot of humility for a shop that has a lot of capacity and capability. I have a hobby shop with a 16" American Pacemaker. Your work dwarfs my capacity!
Cheers mate. I’m pretty grateful to get to do the work in all honesty. I find machining very relaxing and challenging at the same time.
Never a dull moment when I’m spinning big stuff 👊
This is my world. Portable tooling and onsite machining for the win. The challenges of how the F#$% are we gonna do this and then setting it up is where the fun is at. Rigidity is the bugaboo with cantilever style machines overcoming it can be the biggest challenge. looks like you rose to that challenge and managed to win. Thank the gods for ingenious men who make portable tools and the tool rental companies that have this stuff available for our use is all I can say! Great episode Matt you guys are rocking it...Upside down and warm 😁 -10C or so here this morning where I live Brrrrr from New Hampshire USA.
Problem solvers come in every profession. I solve your problem by making your Sheila look her best for you at my salon. The rest is on you. Happy Wife, happy life yeah?
The flange facer was a clever machine, and you gotta love it, seeing good old HSS cutters to the rescue! Happy Holidays, and hope you folks have a great 2025!
Cheers mate, Merry Christmas & Happy New Year!
I have to say that You Australlia guys are awesome. CEE and HAL my god what a diamond discovery. Love the content. I'm cnc machinist on small 3 axis mill and im so stunned buy Your's craftsmanship! Amazing!
Saw this as a rec and had to click it - love seeing problem solving in action! Watching from Jacksonville, FL, USA. Thanks!
Cheers mate! Big G'day from across the pond.
That flange facer is a cool piece of machinery.
This is another Aussie machinist I will watch from UK👍
🇦🇺🇬🇧👊
From California USA; unfortunately I knew it would warp from the welding. It is amazing how much the welding will pull and warp that thick of steel. That stress is still in the steel; but with that light of cuts the warping after the cutting “ I am hoping is not excessive”. Remember that episode at CEE where Curtis had that improperly heat treated steel that kept warping after every cut because of the internal stresses! I would recommend be careful and Do not cut the O-ring groves too deep. Leave enough rubber standing proud of the face so that the O-rings can compress down and seal. With the amount of torque that thing is going to have on it might cause it to start walking around on those bolts and possibly even loosen the bolts.
This is so interesting. I am definitely not going to miss this.
Should have been pre & post heated to as you say to stress relieve
Cheers mate! Yeah it’s an odd work piece to machine hey. We’ve still got the O rings to do in the new year… and I’ll be doing them at the absolute minimum depth. For the reasons you just listed.
Looks like the MEGADRILL should be finished early Feb…
Then, it’s time to SEND IT!
Arizona, US and I think I just found a new favorite machining channel. Thanks for taking the time to explain everything, always good to learn. Merry christmas.
Thanks mate, I appreciate that! 🇺🇸🙏
George from Indiana USA... GREAT JOB ON THE VIDEO
Just subscribed from Salt Lake City, Utah. It’s been mentioned before but you’re turning into another CEEAUS which i mean as a huge compliment. The work you do is fascinating but the videos are a success because you include personal bits with your family and mistakes you’ve made. Your humbleness makes you relatable. Congratulations on your growing success.
Thanks mate, appreciate the kind words. 🙏🇺🇸❤️
Tuning in from South Africa, cant wait to see this project through to the end!!
Merry Christmas to you all! 🎄🎄
Merry Christmas mate! Yeah, we’re all gonna see this bad boy drill real soon.
Should be Auger by end of Jan, and the MEGADRILL by early Feb!
That flange facer is a great piece of kit. Thanks for taking us along!
Happy Hollidays from Louisville Ky. great camera work as well
machinist in Florida. USA. Been at it for 35 yrs. Ive done big work in foundry settings. I know what you are dealing with. Its a challenge but sure is fun to do. Enjoyed seeing your solution to the problem, not seen a face bore before. Very cool to watch.
Cheers mate! 🇺🇸👊
New to the channel from Oregon, USA and CEE channel…great narration and just incredible work
Raleigh, NC and loving your feed! What a great project, guys. Thanks for sharing the process with all us amatures!
This is a machine shop... No problems. Only solutions! :)

That's a great piece of equipment for that particular type of job. I wish America would take a holiday. Many of us have to work every day except for Christmas itself. You remind me of, Kirtis. You're both smart and hard-working men. Hopefully, you have a wonderful Christmas break.
might be a good idea to talk to someone in the gold mining industry. they use those flange facing machines on the autoclave flange faces. the face is overlaid with titanium then machined to achieve a "gramophone" finish so that the chevron spiral wound gaskets willl seat properly. never actually done the job myself, had others who did the machining for us, but it is a very interesting process on a flange that is approx 1500mm diameter.
I'm watching from northern Illinois, USA, northwest of Chicago. I love your content, narration and videography (Karen would be proud). Have a Merry Christmas and Happy New Year! You guys deserve a nice break from your hard work.
This is coming from a Field Machinist running the same types of equipment almost everyday. In this instance I would have gone for an OD mounted machine just for the sake of rigidity and faster material removal. ID Mounted machines are great for certain things but in this case with the heat affected area and many interrupted cuts it wasn’t the best machine to use.
How would you ensure that the flange is perpendicular to the bore with an OD mounted machine? Don't you need a reliable datum surface to mount onto?
@@nrml76 guessing, very long heavy straight axle thru the hole, 2 mounting points in the bore, cutter is centered on the axle, or laser and a very fine hole in the cutter,
maybe even do multiple lasers.
Watching from Minnesota, USA. Have enjoyed CEE for years, just found you. Awsome .

Watching from Central Tennessee USA 😉👍

I'm watching from Ventura County, Southern California (north of Los Angeles), USA! I'm a CEE fan, and I'm glad I found your channel!
Cheers mate! Welcome aboard! 🇺🇸👊
Hi Matt
I suspect a mill would work better for facing the interrupted cut, not sure whats out there these days.
There are contractors in the area that do nothing but machine stuff in place for paper mills etc.
If you get bored troll the Climax machine too website.
HSS has saved many projects for me this summer facing big flanges full of holes.
I would go with a cobalt HSS or even Stellite tools because they will last longer.
Funny there is nothing like a Frenna or wobbly crane in here in the US.
We just use forklifts of all sizes.
Hope you have a wonderful Christmas!
Ross
Cheers Ross! Have a great Xmas mate 👊🙏
great comment - also, Franas are an aussie invention!! They also tip over a lot, not because they suck - sometimfes because in the wrong hands, sometimes because moving under load on construction sites = potholes/uneven ground, holes under surface so then an otherwise pretty static load becomes very dynamic, very quickly, and when moving you aint on outriggers! on even ground and in the right hands they are phenomenal for a lot of jobs and the later models are heaps improved, huge wide wheel base, many axels and can lift a bunch of weight and go for a little drive plus sneak into all sorts of tight areas, especially with the articualtion at the centre and a compact size vs lifting capacity - but still a very risky thing in the hands of a person that doesn't understand the implications/hazard potentials when dynamic loads are at play. Pretty sure some new ones have outriggers too anyway. Anyway - Kurtis at CEE engineering - another Aussie Machinist/metal worker from aus on YT has a whole series of videos doing a complete teardown/rebuild/resto on a 30 yr old Franna that's absoultely awesome content from a guy with loads of brilliant vids - an absolutely top notch, multiskilled/creative fella that many commenters on this vid love watching too i see
Amature 77 year old preacher who now machines in North Carolina, USA! Merry Christmas and God bless!
Wonderful 🙏❤️👊🇺🇸
Matt ,yall are the problem solving masters ,...I enjoy your vids from far western Kentucky usa,...I just wanted to mention a trick i learned from a buddy ,...use it or throw it away ,...when moving an object with the truck crane we found old truck tires useful bunjeed or wratchet strapped to the bumper so the oblect being moved does not damage itself or the crane while bein transported,... sometimes multiple tires are used ,....great holidaze , MERRY CHRISTMAS and a helluva boxing day,...Mike
centre of gavity is further back though, that's why the crane is so long - sure you use commons sense/experience though and get by well enough - but worth metioning for anyone that takes that advice without consideration of implications for load chart related matters - especially if movement under load is a factor - where dynamic loads introduce all sorts of compounded factors - worst of all in that case - deflection/cavities under surface or any number of smaller but compouding factors. that's why contolling the controllable and working below maximums isn't just good practice, it should always be front an centre in setting up for success

Get well soon brother 👊
I love seeing new stuff like this pass across my feed. Im sure the algorithm led me here from how much i watch Curtis of CCEA. And im watching from Cemtral Florida in the US. Gonna be checking more of your stuff out for sure.
Great video, great explanation, and amazing work.
Thanks heaps, appreciate the feedback!
Greetings y’all from the oldest town in Texas, USA, Nacogdoches. Another great video. Merry Christmas.
I might have tried a brazed carbide tool. Tougher than an insert, stays sharp longer than HSS. Or even a solid carbide tool for the same reasons. Of course the heat affected zone could be avoided or minimized by welding in smaller sections or heating the whole thing before welding. But that may just make it worse. May want to consider your order of operations, weld then heat the flange up and allow it to normalize, then weld to the larger part. At least then there would be consistency even if that means consistently wrong.
Can see Curtis now furiously planning out a shop built flange facer.
I’ll be the first to hire it out when he does 🤣🤣🤣💯
Watching in The Philippines. Looking forward to seeing more of your work.
Awesome! Thank you!
Let's do this guy's!
💯👊
Wish you and your team a Very Merry Christmas and a Happy New Year
Cheers mate! Merry Christmas 👊
i'm sure you wouldn't post stuff you can't fix so i'll go ahead and answer the thumbail, preemptively; yes you can?!
Fingers crossed we don’t have a true “Epic Fail” video on the MEGADRILL 🤣👊
I think it would be incredibly interesting to see a video of a project they failed to fix. It's okay to admit something beat you. Then you get to ask for help from the community and learn new techniques like the one in the video!
They sell carbide inserts with not only different coatings but different carbide grades, using a different mixture of carbide and cobalt. The more cobalt the tougher it is, the more carbide the harder it is. Finding the right insert is difficult, since every manufacturer has a different grading system. That’s where a sales rep can point to the best grade for the application.
A large radius provides a better finish in rigid environments but produces more force and will tend to bounce in less rigid environments. A small radius will cut with less force and be more stable in worse conditions.
That is an interesting project. Good job on working through it.
Cheers mate - and thanks for the insight too. Much appreciated 👊
First time here from UK, came from CEE. Subscribed and will binge watch previous episodes. Merry Christmas and a Happy New Year to everyone, wherever you are.
Cheers mate! Have a safe and merry Christmas 👊🙏
Fantastically done, persistence being the driver to success! South Africa
Thanks mate! 🙏🇿🇦
LOTO good on ya. thanks for sharing such a unique machine. Charles
Cheers Charles 👊
Now I have two favorite machining channels,you and CEE! Happy New Year mate from Connecticut USA!
Cheers mate. Happy New Year to you too! 🇺🇸👊
matt, think you earned a few beers after that 👍 should think half the battle is working out where the true centre line is, though that does change static or dynamic. never seen a facer before!
For a guy as young as you, you are learning a wealth of information.
Shout out to Phil the Tool guy. I've never seen one of those before!
Poor inserts, positive inserts dont like interrupted cuts ( stating the obvious). Good old, but not that old HSS.
Immensely enjoyed that job, nice armchair mode, many thanks Matt, excellent engineering 👍.
May i wish you, your family, and all at HAL a merry Christmas and safe 2025.
Watching from Romania, it's great to see how you guys solve all of these problems and all of the machines and tools you use!
UK here. Small machine at home. It was great to see HSS has still got a place in engineering.
It definitely does - especially on the really shitty cutting conditions
Hi & Merry Christmas from the UK! This is the first time I've viewed your channel & have subscribed to follow the progress of that huge boring head. I'm another great fan of Kurtis at CEE so this content is right up my street!!😊
👊🙏
I just now wandered in from southern Oregon, USA, to watch you fellas dig a big hole. This is quite a project. Great video, I subbed.
Welcome aboard good sir! 🇺🇸👊
Dude… that was an education if ever I’ve had one. Never even knew such a bit of kit existed until now.
After seeing what was going on with the inserts my brain went to good old hi speed or tungsten. The cutters I learnt on & you went there too so I was a little chuffed over that, & it worked which was wicked cool.
As for an easier way??? Sent it to Kurtis 😂 he probably won’t speak to ya ever again but it’s still easier.😂😂😂
My very best wishes to you guys. Hope you all have a very merry Christmas & safe & happy new year.
Thanks so much for pitting this channel together. It’s helped me more than you know. Cheers everyone

Thanks for bringing us along , I have done project engineering on five continents and have had to use a flange facer mor than once. You were correct to go to HSS after the first chatter and chip out issue, which by the way is a common issue.
Just found you today. I live in Kilgore, Texas. Been a huge fan of Curtis with Cutting Edge Engineering for a number of years. I am excited to find another Aussie engineering Chanel and really admire excellence.
Welcome aboard! 🙏🇺🇸
Love Texas. Grandma was a proud flyer of the lone star… and NOBODY messed with her 🤣

I am not mechanically trained but enjoy your content. Retired military from Pretoria South Africa. Thanks for the channel. Gerard
Great job. I’m a retired machinist in Canada eh ! When you started the facing job the first thing that crossed my mind when I saw the o-ring grooves was why aren’t they using HSS. Good stuff.
I'm actually seriously impressed with that machine! With the HSS and the very slow RPM, it was essentially doing the equivalent work of an old school shaper ... with nowhere near the mass and stability!
Thanks for sharing 🇨🇦
Most welcome! Merry Christmas mate 🇨🇦👊
I have done a little bit of machining in class and out. This machine reminds me of a portable cylinder borer and a portable valve face restoring machine for steam locomotives. Those are two different machines but are set up on the cylinder saddle for boring the cylinders of the piston and piston valve for the borer and a machine that mounts above the valve face of a slide valve-equipped locomotive to reface the slide valve surface to restore the surface for the slide valve to ride on. Both machines are used instead of removing the cylinder saddle to set up on a horizontal or vertical boring machine or mill to do the job, particularly when the machines are not available where the work needs to be done.
I thought that adding a bar and support through the hole to the other side of the head would add some rigidity to the machine and set-up if it could be done. This would add a longer shaft for the machine to rotate around and be steadier than just the clamps used gave, I could be wrong because of inexperience.
Arp, Texas. In the northeastern part of the state.
Brilliant video and solution to a problem. It always amazes me the range of tools and machines that are out there. Have a brilliant Christmas and a Happy New Year
