Thanks for the comment Warren! Yeah, I’m really grateful to be able to share snippets of the project. It’s the most challenging one we’ve taken on yet.
Harmonics. Can you drill and tap several locations along the non cutting end of your tool bars. Allowing you to screw threaded studs in with various durometer rubber or urethane biscuits and steel plates with more biscuits and washers and nuts to allow you to change the compression on the weight to dampen the harmonics reflecting along the tool bar. You might also want to look at custom studs for the tool post to allow you to dampen the tool post. I really worry about the spindle bearings having to deal with their preload without brinelling the races.
As for your video talents, like anything time and repetition. And above all make the content that you want and those that like it like it and those that don’t won’t 😊

Hi and well done with your thread. Being a drilling rod end it surprises me that your are not using an API thread that are factory ground so you will get the perfect form on both internal and external. It will be interesting to see what the contact is when you mill the opening. Cheers and keep the film clips coming. Ian
I really don't know what milling a slot is going to tell anyone... you need metrology, always. Surely there must be ways to measure, simplest I can think of is three wire method. I wonder about the hand ground tools, to what traceable standard were they ground? The way the tool cuts on in the final stage of the operation looks dodgy to me. Then again, 'quality is conformance to specification' and we don't know what the drawing calls for.
@@ianlangley987 I don't know if blueing a thread is a thing, guess not because it may show a contact pattern but there is no way to correct based on that.
Some great comments here. Trust me I wish we could have just gone with a standard API, but we needed a 3 TPI and it doesn’t exist. For the prototype, the main goal was to see it in the flesh, check we are happy with it… then get custom ground inserts made up. The inserts look dodgy (agreed) but the cutting edges are bang on. The “dodgy” part is having to shape the bottom of the insert to stop the non cutting surface from rubbing. I’m hoping we end up with a tool grinding machine - even for prototype runs in the future. Again, great comments. Love it.
@@halheavyduty In Pt 1 you consistently said "custom" and "prototype" meaning , one off. So even I, who knows little, realises that before larger scale manufacturing can begin you have to step slowly and adapt/amend tooling geometry's, speeds/feeds etc to get it right. Good on ya mate for bringing us on this journey. subbing to see the final Beast in action.

Hi Matt, been watching since your first few videos. The subject matter is of great interest and I look forward to where this particular project is going. As for your videography skills, they've improved but IMO need to get better to grow your channel. My only expertise is having watched a bunch of videos from others so these are just my personal thoughts. 1- tighten up your intro. Keep it under a minute. Eliminate the recapping of information provided previous videos in the series. Keep your comments about what your doing in this video brief, If something needs an expanded explanation do a Voice over as its being shown on screen. 2- Close ups. They are good to show chip size and get the viewer into the moment, however if all you show is what's happening up close the shot looses context. In close up very large and very small things viewers can loose perspective of size. Thanks for giving us a peek inside your industry.
That’s some excellent suggestions right there - thank you! I agree re tightening the intro. I’m going to keep it under 60, and then tune in at the end with any discussion for the people who want to hang around for it. Great ideas re camera work too, and I reckon you’re bang on. To grow the channel, it needs to improve a bunch. Lots of food for thought. Thanks again mate. 👊👊
With videoing I had to video a wedding over 20 years ago and do it so that it could be shown afterwards without any editing - we had no facilities to do so. A neighbour was an ex Channel 9 camera man. When asked for advice, he said look at wildlife videos and see what they do. He also said, don't zoom in and out unless necessary - and not often. Also think about what the viewer will see afterwards. So don't rush, gradually pan across what you want to video. Foe example, in a room, looking at who is attending, gradually pan around the room giving the viewer time (about 2 - 3 seconds) to recognize each person. So gently does it, keeping the camera stable vertically. Lean on something to help with stability. Now remember I had no experience and still have next to none. But think of some of the home movies you have seen and how unstable they are (meaning scatter brained). Then look at wildlife ones and see what techniques have been used. With thought, practice and patience you will be a whizz in no time. But always keep in mind, it is not what you are seeing, it is what the viewer is seeing afterwards, ie fluid, smooth and stable, plus in a logical sequence. PS. If this helps, you can help me. I am on a part pension and can give you my BSB and acct numbers. I only accept denominations in minimum of $1000 lots. Apart from that, hope this helps. Channel 9 cameraman's advice certainly helped me.
That’s some great advice. I’m definitely paying way more attention to how stuff is filmed now. I’ll be sure to check out wildlife videos… and keep zooming in and out to a minimum. Definitely something I do way to frequently right now. Thanks again for taking the time to write that all out. Much appreciated!
@@halheavyduty No problems. I am a self taught machinist, mechanic, mower repairer and whatever else the neighbours dream up, in SW Sydney. My shed (16M x 8M) has a 2500mm x 660mm capacity, MT5 tailstock, Victor lathe from Taiwan. Also a Bridgeport copy mill and a NT40 hydraulic controlled mill. I do a lot of benevolent work in the community through our church but a lot of people have been very kind and given things to me. Have up to 2" P&N drill bit, down to 4mm MT1 and have gear to sharpen all. Have a Repco tool and cutter grinder and with adapters can now sharpen flutes on taps - very happy to have learnt that skill - remember it is a hobby shed and I want to learn all I can. Can also sharpen both faces on horizontal milling cutters. Have made a fine adjustment D1-8 mount for my 3 jaw chuck - can get TIR down to 0.015mm on ground bar - that took many hours and head scratching . Also made a travelling steady to cope with larger roller shafts making new outer housing and utilizing rollers from smaller model. Took collectively 25 hours with local fabrication firm that plasma cut the larger frames. Used my lathe and bigger steady to machine OD of their client's 900mm long x 320mm dia drum - they only have a smaller lathe. Still looking for older manual equipment I can squeeze into the shed like another more capable T&C grinder (and tooling) plus boring and facing head either R8 or NT40. Am 73 yrs old and NC equipment is beyond me - manual one off stuff is what I am into. So if you know of any old gear lying around in the back of anyone's shop I would be very interested. You do good stuff. Keep it up. I am learning heaps. Bob
That’s marvellous Bob. I love what you’re up to mate. Sounds like you’ve got a really well equipped shed too! Hal (grandad) was like that. He retired as a driller at 60, then spent 27 years as a self taught machinist. Being self taught, he was totally unbound by convention or rules and was able to produce some incredibly innovative and quirky stuff. I imagine you’d be very much the same. Hal was beyond resourceful. I still find the odd shop made tool around… and I just stare at them wondering what the heck they were used for.
Do you guys also do large drilling processes in milling machines as well or just focus on lathe? I love watching your channel and trying to see if there are any applications I can bring into the shop I work in
We have two manual mills - a big bed mill and a little Bridgeport style. We don’t currently have much need for CNC milling, but I imagine we will in the near future. I’d say about 80% of what we do is on lathes. Just the nature of the work we do.
@@halheavyduty I love watching lathe stuff and would love to learn more of it. But I know my brain is more mill oriented. Lathe stuff can get so simple that it’s crazy complex and that’s when I get lost lol
I agree. The bit needs a name. No idea what though?! The last one was called the KRASH bit, after the two boilermakers who mostly welded it all up (Krester & Ash) The new big rig itself has a vehicle code DK60… So people have just started calling it Donkey Kong 🦍🤣

@@halheavydutyMust use the names of the rigs from _Armageddon (1998)._
Freedom and Independence I think they were called? I reckon we should call the big bit BRUCE. It'll be interesting to see what we come up with. I might put it out to the channel in a future video. See what cool names everyone comes up with.
Is this proto thread a 29 degree acme? I recently got a left hand and right hand external 4 tpi acme tools and inserts from kenametel they work a treat on 4 hundred serious stainless. Even found i could plunge cut with them . Cheers great channel and content well done.
Thanks for the kind feedback mate! Appreciate it. So its still a 60 degree thread, just not API. It’s a different taper angle and the inserts are considerably larger - as it’s a 3 TPI thread. I bloody wish there was a 3TPI standard insert we could buy off the shelf. The crazy size of the thread is because it’s an RC rod, is it also has an inner tube that gets inserted up the centre.
out of curiosity, why don't you reverse the order of operations and turn/thread the OD first, then bore the ID? I would think that would help with the ringing during threading.
That’s an excellent question! We do the inner section first so I can run a steady to get in there and hog it out with heavy cuts. If I cut the pin first it’ll take significantly longer. Not only that, but the inner profile has a 60degree taper at the very end so I can drive the pipe up it for rigidity when threading. The bit of rubber worked surprisingly well (thankfully). Again, great question.
Thanks brother. Im going to start using both when I describe measurements. Our shop operates in metric and imperial anyway because half of our gear is from the USA 🇺🇸
I’ll start measuring in Wombats 🤣 We are building a mega drill that you could fit 80 wombats in.

Freedom units. We still insist on doing lots of things in fractions like we'd rather stick to £sd even though the British had decimal day. Makes for having a fun index drill set to have all of the in-between, nearest neighbor sizes.
did you run a zero pass before you moved it in 0.1 mm ? ( where you run it agen with out changeing anything. since often the lack of pushing back preasure makes it take just that tiny bit more that does all the diffrence. even in a big big heavy machine when we have vibration problems we just take some big chucktastik strong magnest and put on/ inside the part ( or boring bars sometimes ) and make sure that the spaceing between them is NOT the same between any of them. that way the diffrent amouth of weight at uneven spaceing breaks up the vibration pattern. btw her is a example of how i always do my roughing. witch have recused the wear on my tools dramaticly ( whend from 4 parts pr. corner to over 25 parts pr. coner at the same speed and feed rate ) M08 G0 Z0.2 G0 X50.

Mate, thanks for that! I fully intend on running that to see how it goes. Thank you so much for sharing. Makes sense with the magnet too. Thanks for the explanation as to way - I love to know the reasons / logic behind stuff.

I’d love to chat to you about how I can improve stuff. That’d be great mate. If you can flick me an email & the best way to get in touch, I’ll reach out for sure. Halengineeringaustralia@gmail.com
The size of those chips, bit of salt and vinegar…….sorted 🤭 The dynamic force that the drill rod and drill bit connectors are going to face must be off the chart, how did you guys do any stress analysis to determine materials and sizings ? 😮
We had to for this job. For the production run we will get them properly done, or likely buy a proper machine to do it in house. Really really hard to find people to grind tooling these days for odd custom threads (here at least)
Maybe try adding your voiceover post video recording... I really can't hear what you are saying during recording in the shop but you know that. I'm not a sound engineer but there are thousands of videos on RUclips that record voiceover post video recording. My guess is that it's probably not that hard to do, it just takes more of your valuable time to produce these videos. If you want your channel to grow, this is a must! People will not want to watch more of your videos if the sound quality of your voice isn't clear. I do find what you are doing very fascinating so keep the videos coming, but it's critical (IMO) that you get your audio up to speed. Good luck, and may God bless you.
Hey mate, really appreciate the feedback - and I agree100% Learning bit by bit how to improve it all, and comments like this are really helpful. If you get a minute, can you have a critical look at my last video (the MegaDrill one) and let me know if you think it's any better? Thanks again mate & God bless
It’s called Holemaker. A standard drilling and cutting fluid, but it works surprisingly well. Great rust prevention properties and it never goes off. It also doesn’t have the oily residue… which is great for the hands as we run quick change toolposts 👍
Agreed! We’ve set up a GoPro inside the lathe for future videos. Trying to get vid quality as stable and watchable as possible. Thanks for commenting, and for the suggestion. Appreciate it
I’ve been accused of grinding up the Pink Panther in a previous video… and now the bloody song is stuck in my head every time I fill the coolant tank up 🤣
Hi MATT, firstly a lot better video than last week, glad you got rid of fades, BUT you need to buy a microphone that’s compatible with the camera the sound quality was horrible. Try to stop using so many shots film a bit longer instead. Now with the machining of the diameter you should do a fast clip of that instead it would look way better and people understand its being machined. Then film the entire thread cutting from one position no zoom or movement etc. Jumping from one shot to another can be very annoying and your trying to build a following so slow and steady is the way mate.
Thanks Peter. That’s some really practical advice, and I appreciate it. I’m going to sort the microphone for use when machining… or just do a post film voiceover. Thanks again mate!
It’s a one off custom thread. 3TPI, 200mm long with a 3 degree taper. Custom inserts and proprietary profile. Specifically for the big rig as an RC tool joint. These get screwed (via a custom buttress thread on the other end) to a 1 tonne rod and will drive a 3.0m drill bit. Hope that helps. Thanks for tuning in mate.
We were just altering the thread to cut it deeper. When you adjust the tool wear in the Fanuc programming the way it’s set up, it also adjusts the z axis so it looks like a step cut. Great question 👊
Penny & Murray (everyone calls him Moooray though). He’s the happiest little dude there is and a little MoooRay of sunshine in the shed. Most do the dogs we get here are rescue dogs from either the prison or the police. We’ve had about 20 over the years. Penny is still a liiiiitle cray cray… but we love her. No shed is complete without a good bunch of dogs.
The problem you will face in the future is reproducibility, something not even go/no go standards can identify when it comes to flank angle accuracy. IMHO hand ground tooling will never give you reproducibility required of such a large highly stressed thread. Good tooling suppliers have the ability to make custom ground inserts with close tolerances. Not cheap, I agree but these parts are high value parts and lost production time far outweighs the cost of the custom tooling not to mention your reputation as a supplier. To save wear and tear on the form tooling you might consider roughing out the gullet in steps approximating the final form with standard grooving inserts canted over as required by the helix angle in a similar manner that the lathe steps the down blank prior to finish turning the taper.
Agreed 100% These are a custom prototype for internal use, and the purpose was to see what they actually look like “in the flesh” before committing to investing in custom carbide. It’s been an extremely challenging project all round as it’s so far off the charts (compared to standard commercially available options) Great comment, and I couldn’t agree more. Hand ground inserts suck, and are unsutable for large production runs. Impossible to replicate parts accurately.

@@ianlangley987 I don't know if blueing a thread is a thing, guess not because it may show a contact pattern but there is no way to correct based on that.
Some great comments here. Trust me I wish we could have just gone with a standard API, but we needed a 3 TPI and it doesn’t exist.
For the prototype, the main goal was to see it in the flesh, check we are happy with it… then get custom ground inserts made up.
The inserts look dodgy (agreed) but the cutting edges are bang on. The “dodgy” part is having to shape the bottom of the insert to stop the non cutting surface from rubbing.
I’m hoping we end up with a tool grinding machine - even for prototype runs in the future.
Again, great comments.
Love it.
@@halheavyduty In Pt 1 you consistently said "custom" and "prototype" meaning , one off. So even I, who knows little, realises that before larger scale manufacturing can begin you have to step slowly and adapt/amend tooling geometry's, speeds/feeds etc to get it right.
Good on ya mate for bringing us on this journey. subbing to see the final Beast in action.
Amazing job, threads look good, what type of coolant do you use
It’s called Holemaker. We find it works well and does the trick.
Almost all our machining is 4140 steel, so not sure how it would go for other stuff.

facinating, what type of thread is that?
It’s a custom one we designed in house. A large RC drill rod thread.
@@halheavyduty cool, great job!

Thanks for open this channel, for Your time for Us :D
Good Day Sir

Thank you good sir 🙏👊
Think you need to do voice overs later after filming. Can't understand your explanations of whats happening 😮 all good though, maybe an explanation of your machine etc would be nice.

We’ll definitely be going over the machines in a future video.
They’re perfectly suited to the style of work we do and really good bits of gear.
You can run them as a CNC & they have a manual mode. Colchester Alphas.
Hi Matt, been watching since your first few videos. The subject matter is of great interest and I look forward to where this particular project is going. As for your videography skills, they've improved but IMO need to get better to grow your channel. My only expertise is having watched a bunch of videos from others so these are just my personal thoughts. 1- tighten up your intro. Keep it under a minute. Eliminate the recapping of information provided previous videos in the series. Keep your comments about what your doing in this video brief, If something needs an expanded explanation do a Voice over as its being shown on screen. 2- Close ups. They are good to show chip size and get the viewer into the moment, however if all you show is what's happening up close the shot looses context. In close up very large and very small things viewers can loose perspective of size.
Thanks for giving us a peek inside your industry.
That’s some excellent suggestions right there - thank you!
I agree re tightening the intro. I’m going to keep it under 60, and then tune in at the end with any discussion for the people who want to hang around for it.
Great ideas re camera work too, and I reckon you’re bang on. To grow the channel, it needs to improve a bunch.
Lots of food for thought. Thanks again mate. 👊👊
With videoing I had to video a wedding over 20 years ago and do it so that it could be shown afterwards without any editing - we had no facilities to do so. A neighbour was an ex Channel 9 camera man. When asked for advice, he said look at wildlife videos and see what they do. He also said, don't zoom in and out unless necessary - and not often. Also think about what the viewer will see afterwards. So don't rush, gradually pan across what you want to video. Foe example, in a room, looking at who is attending, gradually pan around the room giving the viewer time (about 2 - 3 seconds) to recognize each person. So gently does it, keeping the camera stable vertically. Lean on something to help with stability. Now remember I had no experience and still have next to none. But think of some of the home movies you have seen and how unstable they are (meaning scatter brained). Then look at wildlife ones and see what techniques have been used. With thought, practice and patience you will be a whizz in no time. But always keep in mind, it is not what you are seeing, it is what the viewer is seeing afterwards, ie fluid, smooth and stable, plus in a logical sequence. PS. If this helps, you can help me. I am on a part pension and can give you my BSB and acct numbers. I only accept denominations in minimum of $1000 lots. Apart from that, hope this helps. Channel 9 cameraman's advice certainly helped me.
That’s some great advice. I’m definitely paying way more attention to how stuff is filmed now.
I’ll be sure to check out wildlife videos… and keep zooming in and out to a minimum.
Definitely something I do way to frequently right now.
Thanks again for taking the time to write that all out. Much appreciated!
@@halheavyduty No problems. I am a self taught machinist, mechanic, mower repairer and whatever else the neighbours dream up, in SW Sydney. My shed (16M x 8M) has a 2500mm x 660mm capacity, MT5 tailstock, Victor lathe from Taiwan. Also a Bridgeport copy mill and a NT40 hydraulic controlled mill. I do a lot of benevolent work in the community through our church but a lot of people have been very kind and given things to me. Have up to 2" P&N drill bit, down to 4mm MT1 and have gear to sharpen all. Have a Repco tool and cutter grinder and with adapters can now sharpen flutes on taps - very happy to have learnt that skill - remember it is a hobby shed and I want to learn all I can. Can also sharpen both faces on horizontal milling cutters. Have made a fine adjustment D1-8 mount for my 3 jaw chuck - can get TIR down to 0.015mm on ground bar - that took many hours and head scratching . Also made a travelling steady to cope with larger roller shafts making new outer housing and utilizing rollers from smaller model. Took collectively 25 hours with local fabrication firm that plasma cut the larger frames. Used my lathe and bigger steady to machine OD of their client's 900mm long x 320mm dia drum - they only have a smaller lathe. Still looking for older manual equipment I can squeeze into the shed like another more capable T&C grinder (and tooling) plus boring and facing head either R8 or NT40. Am 73 yrs old and NC equipment is beyond me - manual one off stuff is what I am into. So if you know of any old gear lying around in the back of anyone's shop I would be very interested. You do good stuff. Keep it up. I am learning heaps. Bob
That’s marvellous Bob. I love what you’re up to mate. Sounds like you’ve got a really well equipped shed too!
Hal (grandad) was like that. He retired as a driller at 60, then spent 27 years as a self taught machinist.
Being self taught, he was totally unbound by convention or rules and was able to produce some incredibly innovative and quirky stuff.
I imagine you’d be very much the same. Hal was beyond resourceful. I still find the odd shop made tool around… and I just stare at them wondering what the heck they were used for.
Just love it when ya tools are on centre height, like a hot carbide thru swarfe mound What was the TPI again?
It’s bloody great ain’t it! Agreed.
3 TPI brother
Do you guys also do large drilling processes in milling machines as well or just focus on lathe? I love watching your channel and trying to see if there are any applications I can bring into the shop I work in
We have two manual mills - a big bed mill and a little Bridgeport style. We don’t currently have much need for CNC milling, but I imagine we will in the near future.
I’d say about 80% of what we do is on lathes. Just the nature of the work we do.
@@halheavyduty I love watching lathe stuff and would love to learn more of it. But I know my brain is more mill oriented. Lathe stuff can get so simple that it’s crazy complex and that’s when I get lost lol
You should give the drill bit a name. How about the Dundee? That's not a drill bit THIS is a drill bit.
I agree. The bit needs a name. No idea what though?!
The last one was called the KRASH bit, after the two boilermakers who mostly welded it all up (Krester & Ash)
The new big rig itself has a vehicle code DK60… So people have just started calling it Donkey Kong 🦍🤣
@@halheavydutyMust use the names of the rigs from _Armageddon (1998)._
Freedom and Independence I think they were called?
I reckon we should call the big bit BRUCE.
It'll be interesting to see what we come up with.
I might put it out to the channel in a future video. See what cool names everyone comes up with.
Is this proto thread a 29 degree acme? I recently got a left hand and right hand external 4 tpi acme tools and inserts from kenametel they work a treat on 4 hundred serious stainless. Even found i could plunge cut with them . Cheers great channel and content well done.
Thanks for the kind feedback mate! Appreciate it.
So its still a 60 degree thread, just not API. It’s a different taper angle and the inserts are considerably larger - as it’s a 3 TPI thread.
I bloody wish there was a 3TPI standard insert we could buy off the shelf.
The crazy size of the thread is because it’s an RC rod, is it also has an inner tube that gets inserted up the centre.
out of curiosity, why don't you reverse the order of operations and turn/thread the OD first, then bore the ID? I would think that would help with the ringing during threading.
That’s an excellent question! We do the inner section first so I can run a steady to get in there and hog it out with heavy cuts.
If I cut the pin first it’ll take significantly longer. Not only that, but the inner profile has a 60degree taper at the very end so I can drive the pipe up it for rigidity when threading.
The bit of rubber worked surprisingly well (thankfully).
Again, great question.
For the metrically challenged, 3 meters is roughly 10'. A 10' drill bit.
Thanks brother.
Im going to start using both when I describe measurements. Our shop operates in metric and imperial anyway because half of our gear is from the USA 🇺🇸
@@halheavyduty Or you could use bananas.
I’ll start measuring in Wombats 🤣
We are building a mega drill that you could fit 80 wombats in.
Freedom units. We still insist on doing lots of things in fractions like we'd rather stick to £sd even though the British had decimal day. Makes for having a fun index drill set to have all of the in-between, nearest neighbor sizes.
We operate in both... and man... I still get half confused with all the smaller in-between fractional sizes that exist.
RIP headphone users! That intro was loud. But I'm excited to see this project, and overall you're doing great for the video production.
Bro I’m so sorry 🤣
So I don’t do it again… was it the music or voiceover?? Still working it all out.
@@halheavyduty Music was a bit hot.
Cheers man. Will be mindful of that in the future 👊
@@halheavyduty It was just the intro music, so the first few seconds. After that it was fine! (I survived. LOL! But it was a surprise.)
🤣👊🙏
did you run a zero pass before you moved it in 0.1 mm ? ( where you run it agen with out changeing anything. since often the lack of pushing back preasure makes it take just that tiny bit more that does all the diffrence. even in a big big heavy machine
when we have vibration problems we just take some big chucktastik strong magnest and put on/ inside the part ( or boring bars sometimes ) and make sure that the spaceing between them is NOT the same between any of them. that way the diffrent amouth of weight at uneven spaceing breaks up the vibration pattern.
btw her is a example of how i always do my roughing. witch have recused the wear on my tools dramaticly ( whend from 4 parts pr. corner to over 25 parts pr. coner at the same speed and feed rate )

use it/test it out if you want and see if you see a diffrence on your machine ( remember to thange the fedd. X and Z value to what you need though. but the main thing is that the thicnkness/depte is constantly verying. since the edge of the material wars most on you insert but if that point/edge is constantly changeing place on the side of you insert the wear is spread out over the entire cutting edge of your insert )
try it out and see how well it works for you
Mate, thanks for that! I fully intend on running that to see how it goes.
Thank you so much for sharing. Makes sense with the magnet too. Thanks for the explanation as to way - I love to know the reasons / logic behind stuff.

@@halheavydutyjust emailed
Thanks brother. I’ll reach out during the week! Appreciate it.
The size of those chips, bit of salt and vinegar…….sorted 🤭
The dynamic force that the drill rod and drill bit connectors are going to face must be off the chart, how did you guys do any stress analysis to determine materials and sizings ? 😮
I’ve got the exact number somewhere… but let’s just say it’s bloody astronomical.
How the rig doesn’t just start spinning and take off is beyond me 🤣
Do you grind the threading inserts in house?
We had to for this job. For the production run we will get them properly done, or likely buy a proper machine to do it in house.
Really really hard to find people to grind tooling these days for odd custom threads (here at least)
Maybe try adding your voiceover post video recording... I really can't hear what you are saying during recording in the shop but you know that. I'm not a sound engineer but there are thousands of videos on RUclips that record voiceover post video recording. My guess is that it's probably not that hard to do, it just takes more of your valuable time to produce these videos. If you want your channel to grow, this is a must! People will not want to watch more of your videos if the sound quality of your voice isn't clear. I do find what you are doing very fascinating so keep the videos coming, but it's critical (IMO) that you get your audio up to speed. Good luck, and may God bless you.
Hey mate, really appreciate the feedback - and I agree100%
Learning bit by bit how to improve it all, and comments like this are really helpful. If you get a minute, can you have a critical look at my last video (the MegaDrill one) and let me know if you think it's any better?
Thanks again mate & God bless
Can I ask what coolant you are using?
If you look at from the first video he tells you then, If it isn't in there keep looking at the next.
It’s called Holemaker. A standard drilling and cutting fluid, but it works surprisingly well.
Great rust prevention properties and it never goes off. It also doesn’t have the oily residue… which is great for the hands as we run quick change toolposts 👍
I think a tripod is pretty much a necessity for making machining videos. Great content though, thanks for sharing.
Agreed! We’ve set up a GoPro inside the lathe for future videos. Trying to get vid quality as stable and watchable as possible.
Thanks for commenting, and for the suggestion. Appreciate it
Great video…❤

Thanks mate! Glad you’ve got a good set of sea legs 🫡👊
have you poured juice on the machine red cooling water🤣🤣🤣🤣
I’ve been accused of grinding up the Pink Panther in a previous video… and now the bloody song is stuck in my head every time I fill the coolant tank up 🤣
Hi MATT, firstly a lot better video than last week, glad you got rid of fades, BUT you need to buy a microphone that’s compatible with the camera the sound quality was horrible.
Try to stop using so many shots film a bit longer instead. Now with the machining of the diameter you should do a fast clip of that instead it would look way better and people understand its being machined.
Then film the entire thread cutting from one position no zoom or movement etc.
Jumping from one shot to another can be very annoying and your trying to build a following so slow and steady is the way mate.
Thanks Peter.
That’s some really practical advice, and I appreciate it. I’m going to sort the microphone for use when machining… or just do a post film voiceover.
Thanks again mate!
No info on the thread profile.
It’s a one off custom thread.
3TPI, 200mm long with a 3 degree taper. Custom inserts and proprietary profile. Specifically for the big rig as an RC tool joint.
These get screwed (via a custom buttress thread on the other end) to a 1 tonne rod and will drive a 3.0m drill bit.
Hope that helps.
Thanks for tuning in mate.
why the step cut?
We were just altering the thread to cut it deeper. When you adjust the tool wear in the Fanuc programming the way it’s set up, it also adjusts the z axis so it looks like a step cut.
Great question 👊
Great fun! What are your dogs' names?
Penny & Murray (everyone calls him Moooray though). He’s the happiest little dude there is and a little MoooRay of sunshine in the shed.
Most do the dogs we get here are rescue dogs from either the prison or the police. We’ve had about 20 over the years.
Penny is still a liiiiitle cray cray… but we love her. No shed is complete without a good bunch of dogs.
The problem you will face in the future is reproducibility, something not even go/no go standards can identify when it comes to flank angle accuracy. IMHO hand ground tooling will never give you reproducibility required of such a large highly stressed thread. Good tooling suppliers have the ability to make custom ground inserts with close tolerances. Not cheap, I agree but these parts are high value parts and lost production time far outweighs the cost of the custom tooling not to mention your reputation as a supplier. To save wear and tear on the form tooling you might consider roughing out the gullet in steps approximating the final form with standard grooving inserts canted over as required by the helix angle in a similar manner that the lathe steps the down blank prior to finish turning the taper.
Agreed 100%
These are a custom prototype for internal use, and the purpose was to see what they actually look like “in the flesh” before committing to investing in custom carbide.
It’s been an extremely challenging project all round as it’s so far off the charts (compared to standard commercially available options)
Great comment, and I couldn’t agree more. Hand ground inserts suck, and are unsutable for large production runs.
Impossible to replicate parts accurately.
