Finally Replacing That NOISY Bearing! | Variable Speed Milling Machine
HTML-код
- Опубликовано: 8 фев 2025
- What we thought was one noisy bearing turned out to be MANY MORE! We are finally going to be replacing the noisy spindle bearing in our milling machine. This is a Hafco MetalMaster BM-63VE Industrial turret milling machine. It is a Bridgeport style mill with a 2J Variable speed drive system and has done plenty of work over the past 5 years. We never really noticed the noisy bearing until we started making videos and getting comments from viewers. So today we show the process of disassembling & reassembling the enter head and drive system and how to replace the spindle bearing. But while disassembling and cleaning the parts we find many more noisy bearings that also need replacing!

send it back to the factory to be rebuilt?
or just get a Mazak cnc which is rebuilt second hand from the factory
Must admit I thought nothing of the noise! Great to give it a good service as you said!!
What is wrong with a Milk crate ladder lol
@@Murphyslawfarm when you are a short arse like Karen she needs 2 crates for his one 😁
Love the variety. From jobs to new workshop additions to tool repair. There’s always something new and it’s always entertaining.
glad you're enjoying it!
@@CuttingEdgeEngineering I would have used a sealed bearing to replace the bad one, rather than another shielded bearing. I bet that black belt dust got down into the bearing and that's why it's bad; because a shielded bearing is not quite as closed up as a sealed bearing.
@@calholli and you think he would not have known that already.before putting the original type in he must have a reason.
@@ronsilvester2944 There is no reason not to have a sealed bearing.. He just replaced it with the same one, rather than upgrading it. But it's fine: he can change it again later..
It's a heck of a lot cheaper to replace some bearings then it is to repair the excess damage done to other parts because of the bearing failing. Timing is always the problem - you don't want to jump on it too fast when it's still working fine, but if you wait for it to completely fail you risk damage to other parts. Great video!
that's the truth, after seeing the inside and how dirty it all was and burnt grease it was good to give it a birthday!
In 1966 I was 13 yrs of age when I didn't know what to do with my future. My neighbor took me with him to the electrotechnical company where he was head mechanic of the department for rebuilding electric motors. It was the time factories had a 2 week summer standstill for servicing all the motors. From 0.75 kW to 200 kW. So it was busy in the shop and in no time I was busy taking electric motors and the attached gearboxes apart, cleaning them, renewing bearings etc. They taught me every thing about electric motors. I wasn't even legally allowed to work! I saw it just as a thing to be busy during summer holidays. When I had to go back to school he came to me and gave me the pay of a mechanic for those weeks. He told me I earned every cent of it. The next year I worked there too during vacation. After that vacation I entered the practicum for electrotechnical engineering at school for the first time and the teacher asked me what I thought of the it. I pointed out to him all the different types of motors he had there with all the specialties of them. He got a bit pale around his nose and told me he had 2 years to to teach me what I already knew.
You brought me back to those years... thanks!
@@CuttingEdgeEngineering Not to mention that failing bearing(s) would eventually screw cutting accuracy all to Hell and back making it that much harder to machine parts to proper size for your customers...
@@dikkiedik53 So an Easy A in that class...
😄😁😆😅😂🤣
@@CuttingEdgeEngineering Well, guarantee the grease you put back was a lot more quality than the original, and you probably got all of the grit from the original casting out as well. Had that, take it apart for service and chunks of the sand from the casting was still in there, right next to the 1S bearings that were noisy. Sand all got moved, cleaned, and the new 2RS bearings went, in minus the one side seal, so the oil fitting could still work. then it got a nice fill of synthetic oil to make them happy. Original was something akin to road tar mixed with gravel....
I've been a maintenance mechanic, machinist, CNC repairman and electrician for almost 50 years. I appreciate all your skill Curtis. You can work on my crew or I will work for you any day. You are truly a dying breed.
Looks straight into the camera with what can only be described as a "defeated look" and says "I'll change that one as well!"
Made me LOL.
As a side note those castings look very well made and clean!
Oh man, me too! That part was perfect!
One of our favorite parts of the videos is when you two laugh together! it's great to see you smile and enjoy each other! keep up the great work.
Thank you! Will do!
I'm blown away that you can take apart that many parts and remember where they all go when you put it back together. I'm sure I'd have three or four screws, etc. sitting there and I'd have no idea where they went. Impressive.
Planning and preparation are key. I use a few muffin trays and label them as I go. Everyone has a process, but I guarantee he is very organized with every part he pulls off. Not to mention, he has a video of him removing it so assembly is easy.
Gears can also be noisy. But god bearings are always a god thing.
simply take a picture before teardown, and when you get lost just at the pictures
Just noisy ? Crazy, but it’s great to see you disassemble something like that and put it back to together. That’s how you keep your business going
He rewatches his wife's recordings to see where all the parts go
I appreciate Homie's determination not to let you stand on milk crates :)
he takes his safety officer duties very seriously
Let's not kid ourselves. Curtis still stands on milkcrates. He's just bribed Karen to not to film that bit anymore.
I swear the milk crates I used to have in the workshop were a damn sight sturdier than the step stool I now have 😅
@@aaronbuildsa I used an 18" (45 cm) slice of a tree log as a step stool, support, and a table to beat on stuff. Get yaself a bay tree log today!
@@CuttingEdgeEngineering I'm sure that you could create a Shop Made Tool that would improve the safety of milk crates. Widen the footprint, link them together, etc. Use good quality tool steel. Possibly Damascus...
I'm not an engineer, but love watching what you do. The camera work and editing is very good, so no boring bits to fast forward through.👍
Wow, thanks!
I agree with you, if it’s going to be boring Karen fast forward’s for me. I appreciate that. Thank You sir & ma’am Very good video as usual
The boring bits are in another video.....
Dude… I’m a nurse and I can’t get enough. Even my 4 year old loves watching this guy!
Well, neither is he -- he's a machinist and fabricator... Big difference...
Do you EVER look back over the video to have to remember where a screw or a bolt or anything has to go? If not, then you are really impressive at remembering pieces and parts! Impressive!!
As an HVAC service tech, I appreciated seeing what preventative maintenance looks like on your machinery. I love doing maintenance when it's planned because you have the flexibility to be thorough and nothing critical is waiting for you to finish the work.
I'm a buildings utility engineer and the number of clients that want redundancies and never failing systems is large, but they seemingly never want to pay, what it takes to actually build redundant systems that can fulfill their demands. 😂
Want 10 walk in freezers that are totally independent and survive a power outage of 1 day? Get ready have 10 condenser units on the roof and an emergency generator in the basement.
@@JainZar1 Probably not you, but a lot of people would be surprised how many 70% efficiency rooftop gaspacks there are still in use. They've all been repaired enough times that it would have been cheaper to rent a crane and replace them all at once, but property managers and owners would rather be penny wise and pound foolish.
@@ethankriegel5957 True, a project I am currently working on is replacing a bunch of R-404A freezers with ones using R-744/CO2 as refrigerant.
@@JainZar1 and then they want efficiency then complain when the condenser is "too big", then they don't want to ever clean them or pay for them to be cleaned!
I would be ABSOLUTELY NERVOUS AS HELL to disassemble a machine like that in fear that it would NOT go back together correctly! BRAVO, a job well done!!
21:05 "I'm gonna change that one as well..." that's a feeling all mechanics and machinists know all too well
I’ve began many conversations with my boss and customers with, “here’s what I’ve found, how far down the rabbit hole you wanna go”?
@@3PumpChumper It's always a lot easier when its' your shit and all you have to argue with is your bank balance, lol.
@@Morgan_Sandoval And that's how I ended up 2 months into "just needs a little cleanup" for my new to me lathe.
@@arthurmoore9488 Restos and rehabs are always forever projects, because you put so much of yourself into it that you can always see something else to improve, adjust, or customize to suit your needs, wants or whims.
Edit: And even when you are finally satisfied, everything needs some good PM lovin' to keep it going.
I’ve said it before and I’ll say it again. Video and especially editing are superb. The professional presentation in this video made a 42 minute video seem like 15 minutes. And I have no need to skip through any segments because you do that for me.
As a retired machinist my heart thumped pretty hard until you explained about the one two three blocks, :]
Got to have at least 1 rough set if your doing machine repair.
i thought exactly the same thing, "those better not be his good blocks!"
Ive never owned an extra set of blocks: my butt clinched automatically 😂
I really appreciate the moments it appears you had a memory dump and your face goes blank and you stare at Karen. The laugh you both share immediately after is so heart warming to see you guys laughing and joking to try to recover. You two and Homeless are so endearing that is why we love you so much. You are a skilled machinist and have so much passion it is contagious! Thank you for a friendly fun and informative start to my day early morning in Alabama USA. Take care and keep up the good work we love to share your day!
Hey mate thanks for watching, glad you can enjoy the video and those moments, the videos take a lot of work and good to know they are being enjoyed 😁👍
The mark of a true professional to make something quite complex look easy.
I absolutely love watching you're videos! You show all aspects of a machine and fabrication shop. Unlike some other channels you also show equipment maintenance and care. That's is something lost in most of today's teachings if we take care of the things we have properly we dont always needs to constantly buy new things. Keep up the great work!
G’day Kurtis,Karen & Homeless,
thanks a lot for another year of the best machining, welding, problem solving, filming/editing and ripping the crap out of rubber toys anywhere on RUclips.
Have a great Christmas and please come back next year. Many thanks to the CEE Team. 🇦🇺🇦🇺
Hey mate thanks for taking time to watch & support the videos we appreciate it! Merry Christmas to you 👍
I think it still definitely sounds better, a lot of the bearings sounded very tired. Also, as others have said, I absolutely love the banter in the bloopers you two have. Great work both of you and thank you for sharing!
endorsed - "a lot of the bearings sounded very tired"
I admire that you can just tear into your mill, fix it, put it back together (without a tin of leftover mystery parts) and get back to work. Good stuff.
Filming the disassembly helps 😃
I was thinking the same thing, start first thing in the morning and have it all torn apart, lunchtime run and get the bearing you need and food, second half of the day is putting it back together and boom ready for the next day. Wish I was that we'll organized an had the time i would need to be able to pull off something like that.
I like when he's fixing some worn out part of a machine and then just says, nah, I'll just make a new one.
BRILLIANT as usual!!! Karen's editing is first class, I can't count how many times my friends would repair something, sometimes expensive machines, and not bother to clean it going back... as always, you set the standard for a "Job Well Done!!!"
Surprisingly, it looks like no one has yet asked to see or hear more about the drift car! Therefore, I will do so. Another wonderful Friday video. We watched it while enjoying our cocktails, as usual. Tearing into a milling machine takes a lot of knowledge and courage. Glad it worked out. Worn out bearings can lead to nasty problems. Thanks, Kurtis, Karen und Homey, from Bruce, Karin, Halgrim and Bella in Germany.
The instant you started tapping on the 1-2-3 block, I said to myself: "comments incoming"... :) Loved the immediate clarification.
To take it all apart and put back together the right way is amazing in itself lol Awesome as always
and there wasn't any left over parts, winning! 😂
@@CuttingEdgeEngineering and you didn't have to make any replacement parts.
@@CuttingEdgeEngineering Do you have to consult the video when putting certain pieces back together? Or do you have a 'system' to how you lay out the parts? Or do you just have an excellent memory?
Curious enough to take it apart. Smart enough to get it back together. Clever enough to hide the extra pieces!
@@d.jensen5153 I'm wondering the same thing... I'm good at tearing things apart but yeah, I always end up with an extra screw (or three) loose! Or maybe they were to start with and THAT's the problem?! 🤣
What a great reminder of a job I did myself about fifteen years ago. "The same bearing sound" isn't a bad thing, and it's always good to begin again with new bearings and an actual installation date recorded. We easily forget the time and frustration of doing so with the years of no trouble that come after.
The nice thing about editing is that all the naughty words that get said in a shop can get edited. LMBO
I like that you're not afraid to tackle anything. It reminds me of myself when I was younger. It is all just mechanical, and it bolts together nothing really difficult if you take your time.
OMG, that was excruciating, watching the amount of time and effort to break down, and it only makes sense to replace all the bearings while you got it apart. On the other hand, I had to chuckle at Kurtis the "Drifter" using the shift knob, and Homey is always a joy to watch. But the image during the outtakes of Kurtis the "drover" riding the mill had me rolling! Yee Haw, giddup! You go Kurtis, Karen, and Homeless!🤣👍
haha glad you enjoyed it mate, thanks for watching
I was impressed that you only used hand tools for the whole rebuild. Well done. A fine machine deserves that type of care.
taking apart stuff... I prefer to use hand tools too; much more precise and control if something goes wrong.
What a LEGEND !!! Finds smallest fail in the system bearings - changes everything to new. Getting new machine effect right after and long after the maintenance is done
Liked before I even watched it! I spent a large part of my career as a Mechanical Engineer (now retired) dealing with bearings and I can say without fear of contradiction that the sound of a failing (or failed) bearing to me is right up there with the sound of fingernails on a chalkboard! 😱
My dad was a WW2 aircraft mechanic and one thing he impressed on us when working on the farm equipment was to always use something else between the hammer and the bearing. For bearings up to 2 1/2 bananas (63.5 mm) we would use a socket that fit over the bearing race. For really large bearings we would use a block of wood in place of the socket.
And that little "pop" when pulling using a gear puller is always so satisfying.
I do appreciate you giving sub-titles for the dimensions. I am a yank and are still trying to learn, and convert to the metric system. As a cabinet maker, all of my hardware is metric. When you have used the American system of measure for more than 50 years, metric is a challenge. Love your videos! Keep up the great work.
good to see a machine being stripped fixed and put back together .... most people would have no idea how to do this ... good vid mate
cheers mate thanks for watching
and well lubricated...was cringing on the first bearings he put in, then he fired a few shots of oil and I was like "YES!!!" Plus all that white lithium grease he put in on the gears and sliding parts, left a smile on my face...cleaned, and restored and well protected for many years of awesome service!
The practical skills you display are second to none! My absolute favourite youtube channel.Many of my non engineering friends now hooked on the team of three from down under. Half a million subscribers in 2023 no doubt about that!
Wow thanks for the support mate, hope you keep enjoying it 😎👍
Hafco have evidently put some very nice effort into building a quality milling machine as evidenced by the overall build quality you uncovered as well as nice details like balancing gears that they could arguably have gotten by with if they'd left imbalances few would notice. But you also added significant value to your own machine by installing better suited-to- purpose sealed ball bearing assemblies, by using polymer composite grease in the main gear case and by scribing the precision visual guideline as a visual rotational axis cross-check. Hafco cut (or spec'd) that top drive gear set "off the involute" to give it more robustness at the expense of gear noise. This also let them specify harder (but more brittle) gears there for better long-term wear characteristics also at the expense of noise. But the machine sure sounds sweeter than it did, and I'm confident you postponed any major maintenance on that machine by hundreds, if not a few thousand, operating hours. As an old manufacturing consultant, you're a joy to watch on the shop floor. Your success as a machinist is as well-earned as your, Homeless' and Karen's work in RUclips production.
Kurtis - your skills never cease to amaze me. And Karen, your videography is first rate! Well done to both of you (from central Oregon, U.S.).
Nice to see the "bearing installer tool" of a socket n mallet is of common use as when I started had the old guys look at me like I was crazy.... if it works, well then it works!
I legit laughed for a bit when I saw that. Here is this channel where some dude is engaging in some very precision stuff on large heavy objects. He's whipped out tools and tricks I've never seen before more times then I can count. I couldn't even imagine how much money he has invested in tools and equipment. So when I saw him using a socket as a bearing installation tool like I do at home..... well I just found it awesomely relatable and funny.
@@ToolofSociety yes a lot of engineers do the same including me.
15:59 I said “YAY” in my head when that came right out. Having pulled bearings with hack a tool in the past I appreciate your assortment and now that I have a lil bit of money I have bought my needed tools too….Gotta love the right tool for the job.
I gotta say, you’re one of so few channels that actually have and use a solvent tank!! Great stuff as always 👍🏻
One of the best videos I've seen so far! It's probably also because I'm a mechanical engineer myself. And then again these cool outtakes that always have tears in my eyes. I wish you both a Merry Christmas and a Happy 2023! Stay healthy! Greetings from the wet and cold (-7 degrees) Bocholt (Germany)
Kurtis has bigger and more balls than a herd of bulls to take something like that apart with so many parts and no instructions. Then to put it back together like he had done it a hundred times. More than just hats off to him.
Before you pulled it apart I had it pegged as gear noise (just because of the rattle)but a new set of bearings won't hurt. Once again interesting, This is the type of work I did for 50 years,
Cheers Billo
Nice job, well done. Loved your take on the 1 2 3 blocks, probably saved about 50 negative comments! They are handy though, use em all the time in the woodshop
Karen made me say something, she knew I would get grilled otherwise 😂
@@CuttingEdgeEngineering She was right! I was about to make a rebuke just as you stopped me!!
@@CuttingEdgeEngineering She's a wise woman! You putting that part in made me laugh because, as @mikeweagle5523 demonstrated, well, I'll just say, it was wise and not get myself into trouble with commentary! 🤣
@@CuttingEdgeEngineering 1 2 3 banana blocks :)
I was about to do the same when I seen it, in my head my best Aussie accent, " what ya doin mate". Then you corrected me.😵
The outtakes are almost my favorite part of all the videos. It’s funny how some people want to call you out for using your tools a certain way. They are your tools and you can do whatever you see fit, with your tools. Thanks for sharing your knowledge and time.
I’d like to say how much I appreciate the quality of editing that goes into your videos. You do great machine work and it is showcased well by skipping over the more tedious parts and emphasizing the points of action.
thank you!
@@CuttingEdgeEngineering You are welcome and you deserve the compliments.
Damn, that was impressive, wow!
Absolutely love how you two interact, the endings are always so funny! 42:11
It's always greatly reassuring when you get to the end of a job like this and there are no bits and pieces left over. 🙂
I caught myself trying to tell you through the screen, that noise is mainly from gears not bearings.
But as you pointed out, it never hurts to replace bearings and clean up every now and then.
I was always that kid who wanted to see how everything worked. So it’s very satisfying to watch you take things apart and back together.
I like the way you treat your machines. You treat them like buddies. When you need them they sure will treat you back like buddies. For a one man workshop I can see your passions in the trade. Thanks for your encouragement!
Great video, lots of information.
That "control box" on the side of the motor is called a pot head or pecker head in my neck of the woods. I have no idea of why but I heard it at my first mining job as an electrician back in 1969 or 1970. I used to repair variable speed gearboxes that used the same Reed style sheaves and belts. My wood lathe uses the same setup today. They work great so why not continue to use them. The ones I worked on had two grub screws per threaded hole to make sure they didn't come loose.
Have a great weekend,
jack
That machine is really served you well first time you've ever done any maintenance on it in 5 years money will spent. I am really surprised they didn't steal that machine up better than that. Stay safe and enjoy the weekend see you on the next one.
Some lads that worked for a few bearing companies told me to chill bearings with dry ice and alcohol if you can't get a hold of liquid nitrogen.
Worked a treat on some Subaru wheel bearings.
Cheers
Love your work
We need to see more on that drift car!
I sold her a few years back to help buy our first home but have always wanted to get another one, maybe CEE can sponsor it 😂

One of the most satisfying tasks of a mechanic - the cleaning station!
Curtis, as much as I love your various videos of you repairing other people's equipment, I have to say there's something surprisingly satisfying about watching you do a shop infrastructure video... especially seeing and hearing the finished product... absolutely beautiful. Best wishes to you, Karen, and Homie in the holiday season and in the new year!
Usually I'm always left with a bolt or two after putting things back together.
It's great that you have video for reference if you don't remember how to put something back.
NO MANUAL:( … I’m BLOWN away! YOU are definitely “PRO” level. I love all your videos. Karen is awesome with the camera,editing. Keep em c’min 😊
The Hunt for a Hundred Bearings. The sheer amount of bearing pullers displayed here was a show of force :-)
Absolutely fascinating to watch someone who knows what they're doing take apart something they're not familiar with and then put it all back together again with no leftover parts. Well done. I know through the magic of editing this didn't take very long but if I might ask, how long did this process take?
Glad you enjoyed it mate, we videoed it over 2 days with interruptions, otherwise would probably only be about 4hr job
@@CuttingEdgeEngineering Did having the video come in handy for figuring out where some parts went? I often take video (and always pictures) when disassembling something unfamiliar to make it possible to find where things go if I lose track.
Yep. As I sat here watching, knowing that if I tried this, the odds of getting it back together in working order if it was me, would be precisely zero. I'm remembering the time I took apart a much simpler tool, then put it together, only to find parts laying on the bench underneath I had forgotten. Taking it apart and then back together the second time did go faster. :)
Err somone who knows what they're doing?
Would have not done all that work and keep the fault intact.
@@agentx7138 He did find multiple bad bearings and was able to clean and degrease/re-grease everything. Preventative maintenance. Now instead of it failing when he has jobs to do it will keep working.
I'm impressed. Screws dropping, tools misplaced, and you still managed to get it back together without left over parts. Right? I used to be able to keep tabs on what I removed and where it goes, but those days are behind me. Fortunately, your outtakes allow me to believe that you don't walk on water. So, maybe I can still tear into my tools to for maintenance and repair.
I have never seen the inside of a milling machine before. Fascinating.
10 out of 10 for the job
Nothing better than a new CEE video with a hot cuppa after removing 4" of heartattack snow off the driveway.... Merry Christmas from Canada, thanks for all the great videos this year!
Merry Christmas! 🎄
79yr old mechanic. I admire your work. My son just rebuilt his Bridge Port. Me, would have leftover parts.
So awesome to have this on video. Not only for reassembly for yourself if you needed it, but will probably end up being an invaluable resource for someone else somewhere in the world. Keep making chips!!
Kurtis, it is a priviledge to watch you work.
At 83, l am a retired, self-trained 'bush mechanic/ fitter who can really appreciate your skill and proficiency.
I also like the cheerful banter with Homey's Mum, too.
Is she a schooled cinematographeror, just a very clever lady?
Keep up your excellent work !
As always... loved the video. you're a brave man pulling that all apart yourself but I imagine that saved a boatload of money doing it yourself. The "BANG" @42:03 and accompanying camera jump was effing hilarious! Thanks for the laugh!
Yep, that bang was comedy gold, I get my Mrs with that all the time 🤣🤣🤣
Thank you for making the video. One of my favorites. It's not customary, but necessary.
Glad you liked it!
If you ever need the motor off the machine again and the spring loaded sheeve is like a Bridgeport, there are a couple of holes so you can cage the spring to make the motor easier to remove and install. Just remove the bottom plate from the motor drive and look for two holes in the plate holding the spring. I saw the holes on your drive assembly, but I don't know if the lower sheeve is tapped. Great job upgrading the bearings in your mill. I was surprised by how loose the bearings were. Thanks again for a great video!!!
I love the machine explanations and fixing videos along with all the other ones. Thnx for taking the time to share the fix . Cheers from Vancouver Island BC Canada.
Thanks for watching!
Yes, this is something I'd be scared to do. Taking complex equipment apart like this would make me highly nervous about being able to get it back together again. Curtis is braver than I am! A *LOT* braver.
He has a Secret Weapon...
Karen is filming everything he does so if he can't remember where a part goes, all he has to do is watch the video of him taking it apart...
@@HappilyHomicidalHooligan 🤣 good one
The taking apart is easy. its remembering where it all goes back together.
@@gl309495 Amen!
Have confidence in yourself, switch the negative thoughts off. It is a series of small jobs that make a complete job, take your time, one step at a time. Having experience obviously helps. But in my experience it always works out no matter how deep a hole you are in.
As my dad used to say whenever the car developed another strange sound... Turn the radio up another notch son.. Worked every time ;) Thx for fun video :)
I just love those satisfying clicks the bolts make when they come undone. The filming quality and timing just gets better and better over time and it's so amazing to see!
As soon as I saw the gears I knew you were never going to be able to make it quiet for very long. My old Van Norman mill has a 3 speed box with straight cut gears and there isn’t an oil on the planet with a heavy enough weight to keep it from howling. Great video! I have Mill envy!
A great example of “if people can build it, people can repair it” . Congratulations on your perseverance and skill, Kurtis.
When you got deep into the disassembly it started getting quite complex and involved. I'm glad you managed to get it all sorted out with no issues. The design of the mechanical speed control was interesting.
One might think that split pully enabling the variable speed is a new innovation but it's rather old. I have a 1964 john deere garden tractor I rebuilt and it has that design to give a range of speed for each gear

I don't know, maybe it's just me, but it is soooo satisfying to replace crusty bearings with new ones and feel the "smoothness".
I'm sick AF and miserable on the couch, interested in nothing; yet, I can focus 100% on this. You're awesome. Thanks!

It's a VS drive head, no matter the brand or where it's made they all have rattles, just turn the radio up a notch and fugitaboutit. Loved the PSA on 123 blocks, people would stroke out if they knew that 123 blocks are on the list of "consumables" in my shop😜
I love a good tear-down and rebuild. Reminds me of the 80's when I worked in the maintenance section of the factory.
I'm an Architectural and Design Model Maker, and my 1,2,3 Blocks and Machinist Squares are my most valuable tools. It's surprising how many machine shop tools and gear we share.
Well...those two dry bearings and the two that seemed to have bad spots, definitely was a good idea to replace em...they more than likely wouldn't have made it too terribly much longer...prevented a catastrophic failure with a seized bearing!
Good stuff...love how Karen jumped when you yelled BANG when you flipped the power switch...LOL!
Keep em coming!!!!
I'm rather impressed with the overall engineered design of this machine, especially the bearing carrier. Makes it a LOT easier to service. There are too many other modern machines not well designed for servicing. Neat vid, thanks for posting!
It is NICE to see relatively new equipment well made from the outset that's maintainable too. In the past, made to last and be maintainable was the norm. There is far too much planned obsolescence currently.
Smart man. You saved yourself time and money by changing all the bearings out while you had it apart. it would suck to get it back together and have to pull it all apart in a year to replace what you could have done while it was apart.
Preventative maintenance can seem like a bit of waste of time but if definitely isn't. If it was done more often maybe your shop would be a little less busy!😉 Happy Friday - Thankyou K, K & H 👍
Great videos!! You are very methodical and thorough. You were right in replacing those bearings. From my experience the 2nd source of noise is the backlash in the gears. You may want to check them and see how much out of spec they are. I replaced the bearings in a Bridgeport and had the same thing happening quieter but still loud. I then check the clearances on the gears themselves and they were way out of spec. I had a frien that had a brand new head that was damaged in shipping years ago and offered them to me. We got them off I replaced them with the newer ones given to me. It was a very quiet mill! Success was sweet.
i gotta believe putting this puzzle back together was a headache you never planned for. Great vid. Karen your a saint. This WAS a satisfying video
Super nice video, with great closeup shots, and provided knowledgeable information throughout the teardown and reassembly, my sincere thanks to both you and your wife for an extremely well-produced video.
Glad you enjoyed it!
Another awesome video James! What would be really cool in my opinion is if you had a little timer on the bottom right or left that gives the actual amount of time you've spent to get to whatever point you're showing in the video. That would allow people to see a realistic guage of time spent on each project. Keep up the great work!
That would be nice also for Isaac & Gregg all 3 get into things that take awhile to get done
I love seeing someone who really knows what he's doing, working with big machines and creating stuff of exceptional quality. Makes my shop look like crap, but there you go!
Kurtis did what he did, as usual. But Karen, you did an amazing job with sound. Hearing all those mechanical nuances is so satisfying. Thank you.
BTW, HafCo should pay you for that. The video really shows how well those machines are made.
Good Morning CEE; Great video this week. Kurtis you are amazing. I would have never tried to tear down a critical piece of equipment that complex. Well worth the effort given the number of bearings you found going wrong. Thanks from Halifax, Canada Have a great Christmas.
Maybe there's some Halifax hashish in the hamburgers? It's really not much complex. Like Kurtis says, follow ya nose and keep at it, sorta thing. You can do it to Mr. Weagle. Keeping the parts where you want them is always helpful. Like taking video of the procedure while tearing it down and paying attention to how it's constructed .
I used to be a maintenance fitter at International Harvester back in the 70's and did the same type of work. Really enjoyed the video brought back memories.
Awesome start to the weekend - thanks for all the work on these videos Kurtis - cheers mate :)
Big thanks to Karen too!
I'm glad to see you again, I really like the way you work👍
Thank you! Cheers!
It good to see someone else clean while disassembled. Cringy when i see others skip the step
I was waiting for the bloopers on this one. You did everything you could to fix the noise and we all appreciate it. I just got new hearing aids and I can hear noises I haven't heard in years. Really enjoy all of your videos and the work you and Karen put in to let us see how proper work is done!
Thank you to all the CEE for this maintenance video on this beautiful Hafco milling machine. Regarding the noise of your milling machine, it didn't shock me personally, the sounds of the machines are their voices and they are unique, but maintenance is always welcome. It's always a pleasure Kurtis to watch you always calm and methodical as you assemble and disassemble a machine. I wish you all a happy holiday season and a merry Christmas.
