Engineer in the United States. Love watching manufacturing vids. It lets me know what troubles I cause y'all machinists. 1 question. Do y'all ever penetrant inspect the parts before they go out into the field? I'd bet a small crack could become a big problem with the forces involved there
Machinist here, what frustrates me most is when an engineer has no idea what he's asking for, and thinks the world works like in his computer. Recent example; Drawing called for a 25H7 thickness of a plate, material delivered was ~25.1mm. What he actually wanted was a flat plate, but he didn't know the symbol for that. We worked around it by adjusting the mounting points, sand blasted the plate to a satin finish and he was overjoyed with the fit and finish. Same engineer wanted a bearing surface to be ground, with an Rz of 3.5... I've also dealt with engineers that demand the strictest tolerances and then never measure it and simply judges the quality by how shiny it is.
I can't speak for the drill rods, but all the structural components on the big rig were built from steel with mill material test certificates and welds were mag particle tested after fabrication
Morning guys, 5.00 am here in Merry Old England, just settling down to catch up, before I head off to my shop, great start to the day, also Rocol RTD fluid yes!

Learning how to hand sharpen a bucket full of all sorts of bits took me awhile. Learning how not make them dull was another. Wow my hat is off to you folks!
15:57 While pecking you punch the drill against the part with rapid. It stops right where you were before a peck. This is most probably why the front gets damaged too early. It may be programmable with a clearance where you rapid 0,5mm before feeding in. This may increase the tool life.
I’ll try and see if I can do it. Other than a blunt HSS pilot drill, we still haven’t had to change an insert on it yet. That thing is bloody tough… And we’ve given it a hell of a pizzling 🤣
Looks like a good candidate for a trepanning tool. Look up David Wilks channel, he shows making and using large trepanning tools. Much less swarf/machine load for large hole boring.
Yeah, I love his videos. We have a trepanning tool (it gets used in the next video actually) but it isn’t quite big enough for this hole. We are about to build a new one for the big rig items. It’ll be a 210mm hole and 1m deep. Will be fun to make.
I worked for a short time at Demag Delaval Turbomachinery in Trenton, PA, USA. Was running a G&L CNC VBM with a 6 foot table. I'd never run anything that big before. I was machining gas turbine impellers for pumping natural gas. Got one on the table, 5 foot diameter or so, reworking an o-ring groove that was brazed up after being cut too wide. That was nerve racking, tickling a few thou off a gazillion dollar part. Indicated the part in with 4x4s and a sledge hammer. The good old days.
Not being a machinist I’ve learned a lot about the skills you guys have watching several channels. Particularly your attention to detail . However, watching you machine these big parts has taught me that the most important skill is probably patience. Without it I think you’d have a bunch of destroyed parts and machines at the end of the day. Very expensive parts and machines.
Patience is definitely the key. I’m regularly reminded… “You’re only once digit or decimal from disaster… take your time and DOUBLE CHECK” And go very slowly on the first run. That’s said… once I’m sure it’s running correctly, we pretty much aim for 60-80% max. And on the odd occasion… You’ve just gotta send it 🤣

Nice vid as always. One issue I see with the kraken is the length of the pilot drill. When it wears it will taper off on the dia and the pilot hole will squeeze around the drill, and rip it out of the locking. When you see the KM pilotdrill it has maybe 5mm length before the full dia bore. Much less squeezable surface.
The nose freaks me out. But it somehow works just fine. I don’t disagree with you one bit by the way… it just seems to work. Oddest design award for sure 🤣
Have you looked in to adding a minimum quantity lubricant (mql) system to your mill? Helps a lot with surface finish and insert life without the moat that an open mill makes of flood coolant.
Hi Matt, again you nailed it with great content, problem with the alpha cnc's are they are just to light for certain tasks but absolutely magic at other applications. That's machining though there is always a compromise to make, nice milling machine it took decent size cuts. Cheers Gary
You’re spot on there Gary. Very versatile, but with limitations. We are looking at a bigger upgrade in the near future for all the “super heavy” stuff.

Ive been watching Kurtis and Karen from CEE(A) for a long-long time. I come from a family of machinist's. I am a hobbyist machinist. Nothing comparable to what you guys do though. However I bring this up in the hopes that one day you guys at Hal... possibly Matt? Could maybe do a colab with Kurtis?? :D That would be awesome!
It’d be great to have him up as a guest and have some fun running The Hulk. It’s an absolute beast to run. He’d love it. I’ve chatted to him & his lovely wife Karen on the phone a couple of times and they’re both top people. I imagine something might happen in the future. They do fantastic work.
i don't think i've ever seen any flats that sized milled out of solid steel. damn. that commercial boring bar looks expensive. can't wait to see this monster in action.
Irs def the biggest square drive I’ve ever seen. The bar was a KM63 head from Kennametal welded onto a shop made shank. Cost about $450 all up in materials, so not too bad. It took about three hours to make.
some big bits doing their job shame the 130mm one had a bit of chatter but in your typical fashion you brought in the reserves and got it done some chips flying round the shop and a boat load for the bin so close now to seeing this thing drill it’s going to be EPIC I say nice work there Cheers till the next instalment Cheers from Up North

Def gonna do a recap video before we dig the big hole! Bring all the new viewers up to speed. Should be a heap of fun. Yeah, our time is kinda 50/50 between repairs and R&D at the moment
Cheers Paul! Yeah, still trying to get the right balance of commentary! Let me know what you reckon of todays vid. Always appreciate the honest feedback 👊
Try to get the Drill Doctor, does a fantastic job at redressing drills. Also, not sure about these diamond wheels but electroplated diamond abrasives and resin infused diamond abrasives shouldn't be lubed for sharpening.
@@halheavyduty Could be. I'm not saying you did wrong, it's just what I read and I myself use it dry. Honestly, this claim would kind of make sense for the resin bonded diamond abrasives as the oil could work its way into the resin and debond diamond stones. At least that's how I see it. But I definitely want to put an emphasis on the Drill Doctor products. They do look extremely flimsy and plasticy but the work really well. Depending on a model there's multiple collet holders for a range of sizes of drill bits. I can relate because you do what I used to and while it's a great skill to have to be able to sharpen a drill bit, the semi mechanised way of doing it with the Drill doctor just gives night and day results compared to hand sharpening. The one I got can even do a split grind.
The Centre drill you had to sharpen, did you consider using an indexable carbide drill there instead for your centre. It might reduce your loading%. No sharpening just index the inserts when needed. Good vid😀 M
It’s funny, but most of these big drills use a HSS centre drill. I asked the same question, but they tend to last longer, and as the surface speed is quite slow in the center, there’s no real need for carbide.
Let me know how I go on this weeks vid bro. Trying really hard to get the balance right. All feedback gratefully accepted and I do pay attention. Cheers mate 👊
Cheers bro! Yeah… so this rod set isn’t even the final “BIG SET” 🤣 There’s another one coming that’s even bigger. And if I know ANYTHING about this crazy company… It won’t be the last 🤣 And I think once it gets drilling I’ll have literally endless content material from all the shit they’ll break hahaha
This channel definitely has potential… CEE does the medium duty but this stuff is some seriously heavy duty machining. One tip you should talk a bit more and kinda explain what and why you are doing certain things.
Thanks for the feedback mate. CEE are light years ahead of me quality wise, but it’s really fun trying to figure out how to make the vids just a little better each time. Loads of room for improvement for sure.
Love the content, look forward to seeing your work . Amazing work and awesome videography I know that it has to be hard shit just running the lathe is enough for me lol . Cheers to you and your team 🎉
Why don’t you use a higher feed I mean it’s higher then everything I used but other people like Abom79 is using 0.762mm per rev is the machine not capable of those feeds and amazing video nice seeing some milling on this Turing channel to is that holemaker coolant premixed with water in those container or is it just the oil and you really must be paying a lot of money for coolant since so much turns into mist and how much power has the hall lathe that it got stopped by that enormous drill and how much load can the z axis produce I also Imagen you run the kraken at 0.07 mm per rev because of the HSS drill bit
Great questions as always bro. 1) Pink lemonade goes in straight and it mixes in the tank. We check it periodically with a refractometer, but mostly by colour… which is surprisingly accurate after you get an eye for it. 2) Hal has about 20kw of power, but the major limitation is Z axis thrust. We are doing work way bigger than what the lathe is designed for, so I just make do. I’ll have to check the exact Z axis stats, but it’s good for up to about a 78mm Udrill… then it struggles. Ideally I want to upgrade to a CNC Megabore with about 50kw and unlimited Z axis…. And about a 420 spindle bore for all the big work that’s coming. Hal does the job for the moment, so no run… but I really want a MEGA set up for the super heavy duty stuff.
@@halheavyduty 20kw is quite strong the strongest lathe in our apprentice workshop has 8KW and a mega cnc would be amazing would love to see a even bigger machine hogging away metal because of a great operator
Why do you not relieve the web, to extend the cutting edge in the centre of the pilot drill for the Kraken. I see the centre of the hole is burnished by the blunt nose of the pilot, and so I wonder if it is deliberately to prevent the Kraken from advancing too quickly?
Main goal is to keep Z axis load lower. I probably should relieve the web more… but just wanted to see what a quick sharpen would do. It dropped it by 8%, so next run I’ll spend a bit more time on the sharpen. Well spotted good sir
I've been wondering why nobody drills a pilot hole before using large diameter twist drills, I know that small twist drills may wander off, especially when drilling deep holes, but I think a pilot hole takes away a substantial part of the forces needed to push the large twist drill in the material. I remember my teacher kicking me in the behind (back in my days this was still allowed 😂) when I didn't use a small drill to start any hole larger than 12mm, but hey, times have changed. In drilling we used the saying that you've got to be able to peel a potato with an ax, maybe this is also a part of it 🤣🤣
If I’m standard drilling, I def ageee with your teacher. The pilot hole should be the thickness of the twist. About 10mm for a 50mm drill etc. It makes a massive difference in the force required… especially when you have to wind the bloody thing in by hand 🤣
We’ve actually never had to machine that much material off a drive sub before. I looked at getting a bigger cutter, but the 50mm one just blasts it out. 8mm cuts and a fairly solid feed made quick work of it.
Yeah bro… I need a power upgrade ASAP. We’re looking at a new CNC megabore that will absolutely smash it out. About 4x the spindle power of Hal with huge upgrades to Z axis. You only appreciate lathe power… when you run out of it 🤣
We have precision grinders for small drill bits, but over 25mm we still do it by hand. Most drills we use are indexable now anyway, so it’s not too often we need to use the big HSS ones any more 👍
Most welcome brother. We did look at a big sharpening machine a while back but I just couldn’t justify it… as we just don’t use HSS as much as we once did.
Hi Matt Always watch your videos In your last video, why did you tig weld the head onto the large boring bar instead of MIG or stick welding it on???Greg NSW
I have a question. Why don’t the steel manufacturers make steel pipe to a certain rough spec so you don’t have literally drill out that massive amount of material from the center?
Making pipes is a different process which often fails to meet customer criteria when it comes to material specs. Also, even if you get pipe which is at spec the price is usually much more than the time it takes to make a hole yourself. What is cost effective is to just have a specialized shop for drilling to make the hole for you. But those are rare, and depending on distance it might not be worth shipping the material for this process alone.
@@Mokkisjeva And DOM (drawn over mandrel) might not be rigid enough for some uses. Billet steel is still the way to go for strength of materials and specific uses.
We can order in hollow 4140 from overseas, but Australia only supplies solid billet steel. The steel needs to meet VERY stringent quality standards considering the application. Hope that answers the question. Boy I wish we could buy hollow 4140 locally. It’d halve my workload
Kong is my all time favourite little bar. If you want to see his big bro in action… go check out the BEAST MODE ON episiode. That thing is a metal monster. It absolutely HAMMERS
Well spotted mate. In this instance there was some minor chatter. It does happen from time to time as the inserts wear. We just leave it… it’ll be coated with grease and grime in no time. These particular threads need a small “crap gap” to allow for all the rubbish that gets caught up during drilling anyway. If you make them too tight it’s a nightmare in the field. It’s small (0.3mm) but it makes a big difference for the guys on the rigs.
@@halheavyduty Agree. My son does material physics PhD and here are many "corrugated" or "modified" surfaces which actually perform better in actual practise. There is a whole battery of science in that area, mostly unknown except to you guys.
2:47 YES!!! Finally ... IDK if you guys s that all the time ..BUT SOO Many times I say "Just use the Cordless Drill ... At the TH-cam screen!! :) ... I've seen So Many Times where the machinist is messing around ... maybe (dangerously) holding a LARGE part by JUST the chuck ... trying to get a Centre Drill in the face at really low RPM and it's all wobbly!!! .... Just use the cordless drill!!! .. I wager you got that within 1mm of dead centre .. not that it really matters that much!! :)
I'm new subscriber and I'm really interested to the coolant you use on the lathe machine if I may ask what is it and what is it called,,thank you for the brilliant content ❤
@@halheavyduty actually I looked it up .. kennemetal makes a through hole pilot drill for that thing. HTS DFT I think? That or modular. Modular would be more fun but definitely expensive.
Hey mate, you’re the PERFECT person for this question (I hope you respond bro) How fast would you comfortably run a 320mm billet with a steady? You do giant parts, so I’d love to know. I absolutely want to try and run it all harder… but I do get a tad nervous when I’ve got a tonne spinning in the lathe. Would love your input bro. Keep up the amazing videos. I always look forward to seeing them.
@halheavyduty Hard to tell. I don't know your lathe, I don't know ridgit it is and how much she can handle. I don't think you can find one video me machining in steady rest. I use it for long parts, but that's about it.
Have you guys ever considered a trepanning setup instead of boring out a 130mm+ hole? If you use 19mm inserts on a 130mm hole, you would cut half of the material by surface area, and save yourself a 92mm bar that you could potentially reuse somewhere else, or sell back to the supplier. And you wouldn't have to do a pecking operation either. Link to example video: th-cam.com/video/HMC8IVCM_HI/w-d-xo.html
We’ve got one that’ll pop up on the next video. It just isn’t long enough to do this particular job. Big fan of trepanning. We just need to build a bigger tool ASAP 👊 Cheers brother. Appreciate the comment
It’s the only part we didn’t build. We designed it, but it came fully assembled. We dedicated our resources (which are limited) to the rods, rig & the actual MEGADRILL bit itself. Wait until you see this thing assembled. Faaaark it looks like an atomic bomb on steroids
All our crossover subs are 4140. You can’t weld it (well) but it is the ideal material for drilling. Hard (but not too hard) If we use milder steel the threads are destroyed in a few holes. Great question by the way.
Great video, though I would like you explaining more what is going on The machining gets a bit repetitive so a voice over will make it more interesting
I’ll try to get more balance. I’m aware I tend to talk TOO MUCH… but I do think things need explaining. Appreciate the feedback mate. Very much. It helps me improve the vids immensely
From memory the compete drill head cost just under 2k. We built the shank setup in house. They’re not cheap, but they save so much time it’s worth the outlay. We have a 50, 63, 110 & 130 in the range. It suits our needs for the moment. I’m about to build a 210mm trepanning tool as well. We have a 186mm one, but it’s getting a bit worn. Need an upgrade for sure
I fully intend on trying it once things settle down a tad. We are so flat out getting this bad boy out to site that I can’t play with much at the moment. Def going to try it though. 100%

Ive been watching Kurtis and Karen from CEE(A) for a long-long time. I come from a family of machinist's. I am a hobbyist machinist. Nothing comparable to what you guys do though. However I bring this up in the hopes that one day you guys at Hal... possibly Matt? Could maybe do a colab with Kurtis?? :D That would be awesome!
It’d be great to have him up as a guest and have some fun running The Hulk. It’s an absolute beast to run.
He’d love it.
I’ve chatted to him & his lovely wife Karen on the phone a couple of times and they’re both top people.
I imagine something might happen in the future. They do fantastic work.
i don't think i've ever seen any flats that sized milled out of solid steel. damn. that commercial boring bar looks expensive. can't wait to see this monster in action.
Irs def the biggest square drive I’ve ever seen. The bar was a KM63 head from Kennametal welded onto a shop made shank. Cost about $450 all up in materials, so not too bad. It took about three hours to make.
@@halheavyduty that's pretty reasonable
some big bits doing their job shame the 130mm one had a bit of chatter but in your typical fashion you brought in the reserves and got it done some chips flying round the shop and a boat load for the bin so close now to seeing this thing drill it’s going to be EPIC I say nice work there Cheers till the next instalment Cheers from Up North
Cheers mate! Yep, had to unleash the tried and tested Kraken to get the job done.
I bloody love that crazy drill now.

It's fun and exciting watching the progress of this massive project.
I wonder what the final invoice totals out at.
Thanks mate! We are all getting pretty excited about the first hole
I started watching at 0500 my time CDT, and am finishing after a long day at the shop at nearly 2100 CDT. The kraken seems undefeated! A beast for sure!
Nice work brother! 👊
Kraken gets the job done 💯🦑
@@halheavyduty Been a long day fixing broken trucks. I envy you and yours making new product for this endeavor. Yes I get that you and the blokes fix broken shite all day long every day. Would be keen to be a part of this massive project! Best wishes on this bit of goodness!
I hope you do a recap video from front to back on this! Will wake the world on what is truly capable to keep men safe.
Def gonna do a recap video before we dig the big hole!
Bring all the new viewers up to speed. Should be a heap of fun.
Yeah, our time is kinda 50/50 between repairs and R&D at the moment
Boy howdy do I ever look forward to seeing all this come together.
Cheers Jim!
Heavy machining takes time !! tks for the content
Most welcome mate. Thanks for tuning in 👊
Great content. New to the channel. Maybe a bit more dialogue of what things are and what you are doing? Kurtis would be proud. Paul, Scotland.
Cheers Paul! Yeah, still trying to get the right balance of commentary! Let me know what you reckon of todays vid. Always appreciate the honest feedback 👊
Try to get the Drill Doctor, does a fantastic job at redressing drills.
Also, not sure about these diamond wheels but electroplated diamond abrasives and resin infused diamond abrasives shouldn't be lubed for sharpening.
Interesting. I was always told to put a small amount of oil on that particular diamond wheel. Could be wrong? I’ll look into it. Cheers brother 👊
@@halheavyduty Could be. I'm not saying you did wrong, it's just what I read and I myself use it dry.
Honestly, this claim would kind of make sense for the resin bonded diamond abrasives as the oil could work its way into the resin and debond diamond stones. At least that's how I see it.
But I definitely want to put an emphasis on the Drill Doctor products. They do look extremely flimsy and plasticy but the work really well. Depending on a model there's multiple collet holders for a range of sizes of drill bits.
I can relate because you do what I used to and while it's a great skill to have to be able to sharpen a drill bit, the semi mechanised way of doing it with the Drill doctor just gives night and day results compared to hand sharpening. The one I got can even do a split grind.
Great content machinist my self respect the work you guys do. BTW love the bessy clamp door lock 😄
Nice! Thanks for that mate.
Well spotted re door clamp 👊🤣
Need a cordess to mega drill adapter. Challenge Hougen to make you a 120mm super deep annular cutter to knock the slug out of the middle.
I like your thinking mate.
That dog knows how to relax. He's got good hair....
He’s once chilled out doggo
Jeez, look at that swarf from the threading tool! That's a hand remover 5000 if ever I've seen one.
Dude… accurate AF
The Centre drill you had to sharpen, did you consider using an indexable carbide drill there instead for your centre. It might reduce your loading%. No sharpening just index the inserts when needed. Good vid😀 M
It’s funny, but most of these big drills use a HSS centre drill. I asked the same question, but they tend to last longer, and as the surface speed is quite slow in the center, there’s no real need for carbide.
You need to talk us through the process mate. I can watch metal turn any day!
Let me know how I go on this weeks vid bro. Trying really hard to get the balance right.
All feedback gratefully accepted and I do pay attention.
Cheers mate 👊
Usual quality content mate, getting 'really' interesting now.....can't wait ✌️
Question is, life after mega drill, what's next ? 🤔
Cheers bro!
Yeah… so this rod set isn’t even the final “BIG SET” 🤣
There’s another one coming that’s even bigger. And if I know ANYTHING about this crazy company…
It won’t be the last 🤣
And I think once it gets drilling I’ll have literally endless content material from all the shit they’ll break hahaha
18:24 having a 10x miles per gallon button is actually genius!
🤣🤣🤣
This channel definitely has potential… CEE does the medium duty but this stuff is some seriously heavy duty machining. One tip you should talk a bit more and kinda explain what and why you are doing certain things.
Thanks! Appreciate the feedback! Will do! 👍
Nice work ! What is the machining cost of such a part in the USA? 10k ?
I’d say $8-10k approximately. It’s for our own gear, so we didn’t charge it out directly, but I’d guess somewhere in that range
Just curious - why did you center drill by hand?
Aussie machining is something to behold!
It’s just easier with the larger billets. Anything over 1000lbs usually gets the hand treatment
C.E.E explains things. You some how dont....Not sure sure of your channel but things can change!!!
Thanks for the feedback mate. CEE are light years ahead of me quality wise, but it’s really fun trying to figure out how to make the vids just a little better each time.
Loads of room for improvement for sure.
Your scrap merchant must love all the clean swarf you send him.
not saying anything but he just ordered another ferrari 😜
They’ve been visiting a bit more regularly since we started this project 🤣
New to your channel. I hit subscribe the moment I saw The Kraken.
Nice! 👊👊🦑✌️

I love the shows from Pakistan, India and Russia. Some serious talent.
Agreed. So much from so little.
That was fascinating to watch. Hello Doggy!
Moooooray for the win!
It's good that you show the brand of the coolant in the video 🎉
No probs. People seem to be very curious about our forbidden pink lemonade 🤣
@@halheavyduty at first sight it looks like antifreeze lol thanks for the reply
👊👍
Love the content, look forward to seeing your work . Amazing work and awesome videography I know that it has to be hard shit just running the lathe is enough for me lol . Cheers to you and your team 🎉
Thanks a million mate. Appreciate the kind feedback
Why don’t you use a higher feed I mean it’s higher then everything I used but other people like Abom79 is using 0.762mm per rev is the machine not capable of those feeds
and amazing video nice seeing some milling on this Turing channel to is that holemaker coolant premixed with water in those container or is it just the oil and you really must be paying a lot of money for coolant since so much turns into mist
and how much power has the hall lathe that it got stopped by that enormous drill and how much load can the z axis produce
I also Imagen you run the kraken at 0.07 mm per rev because of the HSS drill bit
Great questions as always bro.
1) Pink lemonade goes in straight and it mixes in the tank. We check it periodically with a refractometer, but mostly by colour… which is surprisingly accurate after you get an eye for it.
2) Hal has about 20kw of power, but the major limitation is Z axis thrust. We are doing work way bigger than what the lathe is designed for, so I just make do. I’ll have to check the exact Z axis stats, but it’s good for up to about a 78mm Udrill… then it struggles.
Ideally I want to upgrade to a CNC Megabore with about 50kw and unlimited Z axis…. And about a 420 spindle bore for all the big work that’s coming.
Hal does the job for the moment, so no run… but I really want a MEGA set up for the super heavy duty stuff.
@@halheavyduty 20kw is quite strong the strongest lathe in our apprentice workshop has 8KW and a mega cnc would be amazing would love to see a even bigger machine hogging away metal because of a great operator
Why do you not relieve the web, to extend the cutting edge in the centre of the pilot drill for the Kraken. I see the centre of the hole is burnished by the blunt nose of the pilot, and so I wonder if it is deliberately to prevent the Kraken from advancing too quickly?
Main goal is to keep Z axis load lower. I probably should relieve the web more… but just wanted to see what a quick sharpen would do.
It dropped it by 8%, so next run I’ll spend a bit more time on the sharpen.
Well spotted good sir
I've been wondering why nobody drills a pilot hole before using large diameter twist drills, I know that small twist drills may wander off, especially when drilling deep holes, but I think a pilot hole takes away a substantial part of the forces needed to push the large twist drill in the material.
I remember my teacher kicking me in the behind (back in my days this was still allowed 😂) when I didn't use a small drill to start any hole larger than 12mm, but hey, times have changed.
In drilling we used the saying that you've got to be able to peel a potato with an ax, maybe this is also a part of it 🤣🤣
If I’m standard drilling, I def ageee with your teacher. The pilot hole should be the thickness of the twist.
About 10mm for a 50mm drill etc. It makes a massive difference in the force required… especially when you have to wind the bloody thing in by hand 🤣
It's surprising that you don't have a much bigger cutter for milling those flats.
We’ve actually never had to machine that much material off a drive sub before.
I looked at getting a bigger cutter, but the 50mm one just blasts it out. 8mm cuts and a fairly solid feed made quick work of it.
Seeing that machine struggle to drill that hole makes me value the amount of OOOMPF my CTX 2000 has on the main spindle
Yeah bro… I need a power upgrade ASAP. We’re looking at a new CNC megabore that will absolutely smash it out.
About 4x the spindle power of Hal with huge upgrades to Z axis.
You only appreciate lathe power… when you run out of it 🤣
Pivitol point of your business is drilling and you sharpen by hand, was expecting precision grinding great videos 👍👏🏻
We have precision grinders for small drill bits, but over 25mm we still do it by hand.
Most drills we use are indexable now anyway, so it’s not too often we need to use the big HSS ones any more 👍
@@halheavyduty thank you so very much
Most welcome brother. We did look at a big sharpening machine a while back but I just couldn’t justify it… as we just don’t use HSS as much as we once did.
Hi Matt
Always watch your videos
In your last video, why did you tig weld the head onto the large boring bar instead of MIG or stick welding it on???Greg
NSW
It’s less likely to crack. Honestly it makes marginal difference, but I prefer them TIG welded on.
how many of these drilling rigs going to be built?, is this a prototype/one off or start of production? excellent stuff matt 👍👍
The “big rig” is currently a one off prototype… but I have a sneaky suspicion that if it’s a full success… it’ll get a fleet of friends.
I have a question. Why don’t the steel manufacturers make steel pipe to a certain rough spec so you don’t have literally drill out that massive amount of material from the center?
Making pipes is a different process which often fails to meet customer criteria when it comes to material specs. Also, even if you get pipe which is at spec the price is usually much more than the time it takes to make a hole yourself.
What is cost effective is to just have a specialized shop for drilling to make the hole for you. But those are rare, and depending on distance it might not be worth shipping the material for this process alone.
@@Mokkisjeva And DOM (drawn over mandrel) might not be rigid enough for some uses. Billet steel is still the way to go for strength of materials and specific uses.
We can order in hollow 4140 from overseas, but Australia only supplies solid billet steel.
The steel needs to meet VERY stringent quality standards considering the application.
Hope that answers the question. Boy I wish we could buy hollow 4140 locally.
It’d halve my workload
@@halheavyduty
I see! Thanks for the response. Well, I guess you keep drilling and I keep watching!
I HAVE to see what it going to turn this big thing. It's gonna be epic.

Nice diamond sharpening set up, I'd offer to sharpen it for you but I don't think it would fit in my $90 knock off Drill Doctor
🤣🤣🤣
I'm seeing chatter marks on one of the threaded sections. Are these refined, or left in-place for mechanical interlocking reasons.
Well spotted mate. In this instance there was some minor chatter. It does happen from time to time as the inserts wear.
We just leave it… it’ll be coated with grease and grime in no time. These particular threads need a small “crap gap” to allow for all the rubbish that gets caught up during drilling anyway.
If you make them too tight it’s a nightmare in the field. It’s small (0.3mm) but it makes a big difference for the guys on the rigs.
@@halheavyduty Agree. My son does material physics PhD and here are many "corrugated" or "modified" surfaces which actually perform better in actual practise. There is a whole battery of science in that area, mostly unknown except to you guys.
2:47 YES!!! Finally ... IDK if you guys s that all the time ..BUT SOO Many times I say "Just use the Cordless Drill ... At the TH-cam screen!! :) ...
I've seen So Many Times where the machinist is messing around ... maybe (dangerously) holding a LARGE part by JUST the chuck ... trying to get a Centre Drill in the face at really low RPM and it's all wobbly!!! ....
Just use the cordless drill!!! .. I wager you got that within 1mm of dead centre .. not that it really matters that much!! :)

If it’s over 100kg, I use the drill. Fook messing around with heavy shit like that 🤣
Good to see this processing
Cheers mate 👊
I can’t believe the “ribbons” of swarf the kraken is making!
If I had more Z axis push I’d be cranking out Doritos 😜
I'm new subscriber and I'm really interested to the coolant you use on the lathe machine if I may ask what is it and what is it called,,thank you for the brilliant content ❤
Most welcome mate. Glad you enjoyed it.
Just realised your in rocky from looking at the back ground hahaha bit disappointed in that shit ozito drill tho😂
Hahaha. It’s shit alright… but at least the mechanics don’t seem to want to steal it 🤣
Does the job. Just…
That thing is just asking for a 25mm U Drill or one with through coolant and a replaceable tip.
💯
@@halheavyduty actually I looked it up .. kennemetal makes a through hole pilot drill for that thing. HTS DFT I think?
That or modular. Modular would be more fun but definitely expensive.
7:03 What's the HP on that thing. If your spindle load is below 100%, you're going to slow. 😉
Hey mate, you’re the PERFECT person for this question (I hope you respond bro)
How fast would you comfortably run a 320mm billet with a steady?
You do giant parts, so I’d love to know. I absolutely want to try and run it all harder… but I do get a tad nervous when I’ve got a tonne spinning in the lathe.
Would love your input bro. Keep up the amazing videos. I always look forward to seeing them.
@halheavyduty Hard to tell. I don't know your lathe, I don't know ridgit it is and how much she can handle. I don't think you can find one video me machining in steady rest. I use it for long parts, but that's about it.
Thanks for taking the time to reply Chris. Appreciate it mate 👍
Awesome fantastic work 👏 ❤
Thanks mate 👊
Re name Kraken, Medusa. Wild snakes man. (Retired tree surgeon, UK.)

Well spotted. I’ve found it works pretty well for The Kraken. Most Udrills I just run a simple G code program
Gonna need a bigger drill chuck…🙃😝🤘🏻
💯🤣
Have you guys ever considered a trepanning setup instead of boring out a 130mm+ hole?
If you use 19mm inserts on a 130mm hole, you would cut half of the material by surface area, and save yourself a 92mm bar that you could potentially reuse somewhere else, or sell back to the supplier.
And you wouldn't have to do a pecking operation either.
Link to example video: th-cam.com/video/HMC8IVCM_HI/w-d-xo.html
We’ve got one that’ll pop up on the next video. It just isn’t long enough to do this particular job.
Big fan of trepanning. We just need to build a bigger tool ASAP 👊
Cheers brother. Appreciate the comment
Did y’all build the auger? That thing is gnarly.
It’s the only part we didn’t build. We designed it, but it came fully assembled.
We dedicated our resources (which are limited) to the rods, rig & the actual MEGADRILL bit itself.
Wait until you see this thing assembled. Faaaark it looks like an atomic bomb on steroids
Yeah Buddy!!!!
Is 4140 the typical steel for the drive subs for augers? Wouldn't you want something less hard?
All our crossover subs are 4140. You can’t weld it (well) but it is the ideal material for drilling.
Hard (but not too hard)
If we use milder steel the threads are destroyed in a few holes.
Great question by the way.
Good lookin pup!
He’s a good boy
Great video, though I would like you explaining more what is going on
The machining gets a bit repetitive so a voice over will make it more interesting
I’ll try to get more balance. I’m aware I tend to talk TOO MUCH… but I do think things need explaining.
Appreciate the feedback mate. Very much. It helps me improve the vids immensely
When do you not need cooling liquids?
You can dry machine most things, but tool life is lessened.
That said, Udrills and HTS drills absolutely need coolant
Lots of it 💯👊
@ Thanks. Wishing you continued success. Westerville, Ohio, USA
Thank you my friend!
HAL must stand for huge ass lathe
🤣🤣🤣💯
matt how much does some of this giant tooling cost down under, like the 130mm drill?
From memory the compete drill head cost just under 2k. We built the shank setup in house.
They’re not cheap, but they save so much time it’s worth the outlay.
We have a 50, 63, 110 & 130 in the range. It suits our needs for the moment.
I’m about to build a 210mm trepanning tool as well. We have a 186mm one, but it’s getting a bit worn.
Need an upgrade for sure
