Being a retired Heavy Engineer from a Naval Dockyard I spent most of my working life machining and boring shafts, flanges and mating face on large heat exchangers, boilers etc. We did not have CNC all had to be worked out by hand. I am glad to see a new breed of engineers tackling these tasks. If I was not 85 years old and lived in the UK I would give you a couple of days a week just to keep my hand in lol. Keep up the good work - love the channel brings back many a happy memory.
That’s awesome Paul. It’s men like yourself who have a world of skill in a trade that nearly got lost. Fortunately I sense a resurgence of interest in machining, so people are learning and curious once again. My friend, if you were here we’d likely have you in the shop tomorrow. Hal himself worked half days until he died at 88. Thanks so much for tuning in. I’ll be on the lookout for future comments of yours good Sir 👊🫡
Morning Paul, hope you're keeping well, I'm Italian originally been in the UK 24 years, did GNVQ Engineering at school when i moved here and recently found the passion for Manufacturing Engineering at 37 year old. Please stay active in the comments section, would love to hear some of your stories :)
once upon a time all workshops were like that: real men, working hard, having a laugh, having a beer after work, not being offended. you have a good team there. keep it up and keep it real.
Thanks mate, that's what it's all about 🙏👊💯 I’d safely say we’re about the least policitcally correct workplace on earth at this point 🤣 The crew went to Vegas for the 60 year celebration and the tour shirts literally had three options printed on them “60 years strong” “Bores & Whores” “Your hole. Our goal” Fully approved by the big guy 🤣
🤣🤣💯 The fab shop boys come up with some bloody funny setups some days. I used to work in that part of the company and loved it. Nothing quite like melting steel together on a cold morning.
my early years i was a marine fitter turner on the melbourne water frount (now retired) its fantastic to see your work and the aproach you take, enjoying your content. Just note to the USA friends, its Australian 40 amps, 3 phase at 415 volts (phase to phase) which is aprox 20kw assuming a power factor of .7 for a non power factor corrected motor which is about 27 british horse power.
Thank you for clarifying that for my American friends! Appreciate it good Sir. And thank you for the kind feedback. I feel really grateful to do what I do, and to be able to share some of it with the wider community of people who share my interest in machining.
Sorry fellas, I've been commenting and getting replies and forgot to subscribe. Thats been corrected. Enjoy how you show the other aspects of the trade, Welding/Fabrication. Because what we do often is preparation for the Welding process. If the machinist gets right, the welder gets it right. Have great day fellas, From USA!
Really starting to get a clear idea on the size of this monster. Some beautiful work being done. Watching Kong always makes me smile, it almost has an attitude ‘bring it on !’. As well as a gas axe being used used like a surgeons scalpel, makes me wish I’d stayed in the heavy side of engineering as a boy. Can’t wait for further big rig updates 😊
Cheers Nick! Yeah. I bloody love that chonky little bar. Not the biggest, but it can take some heavy damn cuts and doesnt even flinch (normally haha) I do miss the boilermaking side of things occasionally (that's where I started in heavy duty world). Nothing like flame cutting and melting steel together in the morning!
Cheers Rob. I’ll pass that onto the fab team. They’ll love that. Those guys bust their ass and do a great job. Really lucky to be surrounded by some very good tradesmen.
When you were measuring the chips and you got 7.99mm on the caliper, the drawing underneath said "8", I had to watch it again as I thought you must be measuring a part! Just a coincidence. Great video, looking forward to the next one already. 👍👍
I was super curious just how heavy the eccentric cuts were. I think 8mm DOC might just be Kong's upper limit.. That said... there's only one way to find out. I'm going to test it in a future video when the parts aren't boring quite so deep. I think Kong could comfortably knock out a 10mm cut.
Don't buy that new lathe until you can get a control for it that can reduce the eccentricity in steps on each pass. Your pieces are big enough that the cross-slide can easily keep up. Great video as always, you're a natural for it.
Thanks so much Jim. I’m looking into your suggestion this week! If you’ve got any more info or suggestions, please email them to halengineeringaustralia@gmail.com I’d love any tips you’ve got that could lead to improvements in how we run the machines. Sounds like you really know your stuff!
Nice shop, thanks for sharing. The boring bar holder looks like it can do a good job. I made one for a 125mm boring bar setup for sterntube turning. It worked well on heavy cuts, but was not very good for fine turning, with vibes and bad surface. Maybe the bar was too hard quality steel. The storebought damped bars I have seems to be very soft material and works like a dream on fine cuts.
Interesting! I’m curious to see how the big bar performs. I’ve got a few wild odd jobs in the pipeline this month, so ol Godzilla is gonna get a workout.
Man! You guys have got a real tiger by the tail with this project! I used to work in the HDD industry here in the states so my downhole equipment was playthings compared to what you’re building. Keep the vids coming! I’m laying here one week post-op from a knee replacement so I can’t do a damn thing but watch! Cheers to you guys gettin it done down under! 🇦🇺🇺🇸

Thanks for the kind words Bradley! Appreciate it mate, and welcome to the channel. Yeah, I’m a long time viewer of CEE. Karen & Kurtis are great. Such lovely people.
I’ll be filming it when she has the maiden voyage! It’s only 3m… but it’ll be insane to see regardless. 1.8 is our current record, so it’s almost double that.
Love it, i can only imagine a workday there and it's putting a smile on my face. Question, are you heating the flanges up once they are on the big tubes so that there's no gaps when you finally weld it to ensure the strongest bond between the two parts?
I genuinely look forward to work every day. I feel really fortunate to have found something I just wake up and can’t wait to get stuck into. We preheat the material so they don’t crack during welding. If you don’t get the flanges heated to the correct temperature, they crack as it cools.
Have you considered drilling and tapping 2 holes at the rear of the kong head for stability? You could have threaded rods will a ball bearing pressed into the end and screw them in enough so they roll on the machined surface you have just cut. So they should roll pretty smooth but give additional support opposite to the cutting head. And each paas, just screw them out to the next distance and lock nut them there.
Interesting concept! The plan is to fire up Kong big brother (Godzilla) and use him instead. It’s a much more rigid bar… and the interrupted cuts don’t even make it move. A bloody weapon. Very clover idea though. I like your thinking Chris.
@@halheavyduty i also thought a triangular steady rest or 2 would be good for the long shafts with smaller diameters for the same reason. if you have them slide on the boring bar you could have a central shaft so they roll on the inside where your outer steady rest sits again for stability.
Deep boring definitely presents it challenges. I havent invested in a long anti vibration bar yet, but I suspect we might need to. Fortunately, due the hole size I can just keep making fatter bars haha.
More good machining Matt. It is always best to try and take a full depth cut so the insert is not running in and out of the mill scale as that will just take the edge off the insert very quickly. Great looking rig and will be looking forward to seeing it in action. Cheers Ian
Cheers Ian. Yep, agreed 100%. If you go lighter on the cut it runs way way worse. Just go full depth, buckle up and give old Kong a workout haha. I cant wait to see the big rig in action too!
Seeing a giant boring bar like Kong deflecting like that is crazy also getting machining time from 6 hours down to 4 is insane also aren’t you tempted to drink the lathe juice looks amazing also how long do you run a tool until you change the cutting edge on a insert also I thought Kong was giant but now Godzilla that like stuff Curtis will do with his 1 meter boring bar it was I think
It’s wild on the super heavy cuts! But man it makes the sweetest sound as it chomps away. I can’t wait to give Godzilla a proper trial in his new setup. That bar is rigid AF and just loves heavy cuts.
Won't be long. There's a big 500kg billet of steel sitting outside on a pallet that has a date with the Kraken & Godzilla. Cant wait to get into that one!
Great to see another Aussie machining channel! I'm curious about that red coolant, I've only ever seen water/oil mix used - which appears white. What is that coolant?
Cheers mate. The coolant is called HOLEMAKER (by ITM). It's a fairly standard cutting fluid, but it suits what we do really well. Much better than soluble oils in my opinion. It doenst go off and seems to do the job pretty well.
You’re not wrong there mate. It’ll be the biggest rig in the fleet by far once it’s finished. The drill bit is powered by a custom built hydraulic top head drive. It’s enormous and weighs about 5 tonnes!
Well spotted. It’s an air RC drill. Custom rods & bit. We’re pretty sure it’ll be one of the largest of its kind when fully operational. There are large raise bore & mud RC machines out there, but we had to build it custom because we couldn’t find an air setup big enough.
First time watcher and diff a new subscriber. Very cool to see this wild scale of machining. What's the need for a hole 3M dia? And what happens at 250m deep, which is crazy stupid for that dia. but 250m deep by itself is nothing so special. Somebody should film the drilling process as I'm sure everything involved will have to be totally nuts. I'm looking forward following along. Thanks for doing this, and here's hoping for success. Nice that CEE has a great number of followers; you're next!
Thanks for the kind feedback mate. Yeah, so the holes are intended for underground mining saftey / ventilation shafts. The major advantage of this style of drilling is that it uses reverse circulation air, rather than mud - and drills from the surface to depth (as opposed to raise bore methods). There's bigger drills out there, but none that drill with this style of tech. PS It'll all be getting caught on camera. We're documenting the entire journey, as this is the biggest (and most custom) project we've ever undertaken. It's bloody wild.
Hey, did you make custom steady covers for all diameters you work on? Notice a nice close fit. Hell we are lucky to cover rollers with so many different diameters, we just re use whatever laying around to protect rollers from chips
I made them for cutting the big HAL316 threads, and will probably make a bunch of sets in the future It works really well, and makes a big difference when you’ve gotta work close to the steady.
You are going to tell me. Why the wobble? I sat there with my mouth half open. Thank you for showing us what you do. (Nothing to do with the show) Matt I think that you are proud of your beard, I can see that you go to a lot of trouble looking after it. It looks good.
The wobble only happens on the very first pass. The material isn’t totally round inside, so the cut depth varies as it machines it out. One side is 4mm… the other is about 8mm… hence the “wobble” The old beard has gone full bushranger as of late. My barber just retired and I haven’t had time to chase another one yet 🤣 Appreciate the comment Colin 👊
Thanks for the diversified content and the peek into your fab shop. While I do enjoy the footage of your jeweler's lathe (did you really say the spindle bore was 320 mm?), the rest of the operation may be more interesting. BTW, the Turkish Hydraulic Cylinder Factory channel has some recent videos with a truly monstrous cross slide boring bar.
I’ll have to check that channel out! Sounds super interesting. Yep. The Hulk is an 11 tonne monster with a 320 spindle bore. Each chuck weighs about 300kg. It’s basically a gym workout to operate it. We love the big green machine 🤣
Like all ya videos just great watching this big stuff being done the n the how to get it done i now only play around in my shed doing mostly of all things gun smithing as being Forced into retirement from bad knee to loosing the battle and having it removed makes getting around a hole diferent ball game This build is Epic to say least But my prediction is is first up use its goner break some thing this is a massive Drill for sure can only emadgine the power to get it to drill a hole will be very good to see it drill for sure after all the hours of swet n tears to get to this stage good on you and your team major Effort all round Big Cheers Ps you say central Queensland would that be in the Mackay Emerald region
Cheers mate! I sure hope nothing too critical let’s go on the maiden voyage. We’ll be naming the rig THE TITANIC if it does hahaha Close! We are based just outside Rockhampton
@@halheavyduty will be a great day to see this drill in action i don't think the drill will give i think the rig driving it will Just out of Rockhampton great place i grew up there so its home for me all thow live farther north in Townsville Cheers thanks for the reply
Totally agreed. We are right in the process of building a super sturdy cross slide boring bar / drill holder. The toolposts we have are fine for external turning and shallow boring, but not for heavy duty deep boring a drilling. Fun project. Should have it up and running next week
tip on rebrazing the PCDs in them pilots... dont preheat the carbide ones by shoving an oxy up the inside. how i always did the steel body ones. client just shrugged... "meh, got it cheap second hand... worth a shot!"
Will you put a video of this drill rig running or not? My old timer friend had a business here in Alaska and he had two Hughes drills that would do 3 m holes, but he never had bits to do that big. I’m a machinist do you like that coolant you’re using? Does it ever break down or separate or coagulate cause gum up on the machines? What brand of coolant is it? you talked about it a few a month or two ago I didn’t write it down. I’m interested in trying that coolant .
We will definitely be doing a full video of it in action once it all comes together. The deadline is late August / Early September… hence why we are round the clock full steam ahead with it all. The coolant is called HOLEMAKER. I love the stuff. No residue, no gumming up of machines, doesn’t separate and never goes off. We haven’t noticed any decrease in carbide performance, and it has excellent anti rust properties.
@@halheavyduty you should mention that as I'm sure most of us have no clue why you need such a big ass hole in the ground other than bragging rights ;)
I thought I did… But there were a few takes and I honestly can’t remember if it made it to the final edit 🤣 I’ll make sure it gets mentioned next time for sure. Whatever it’s for… fark that’s gonna be one big hole 🤣
5:39 i see that you guys use what we call "land bridges" ( at least the places i been ) and i clearly prefer them over the rubber mats. though i like mine with only 3 underline pens instead of 5. so there is some more flex inbetween the the underline pens. but each there own i guess reminds me. i did see a nefty trick to line up tools and parts with a hole/ round feature. you take a round wireless camera in the spindle/chuck and spin it at somewhere between 10 and 110 rpm's and when the round feature/ hole dont jump around on the screen anymore you know that it is exactly on center of the spindle/chuck ( like if you have a small drill in the tool post. you need to be every precise and both hight/centerline but also in X. you then take a cheep wireless microscope. put it in the chock and spin it around. if its not standing still your not in center and have to go up or down in the toolholder or side to side in X. or if you setup a workpeace in the mill and you have to drill a hole down inside another hole that was already there. you put that microschope in a toolholder and spin it on till the hole in the part stands still on the screen. and you dead center in the hole ) im planing to try that same methode on a normal toolholder for the tool post and see how well it works for just setting the tool at perfect tool high in the toolpost ( i let you know when i tried and how well it works )
Definitely let me know how it goes! Interesting method indeed. I love the creative ideas that people invent to solve problems in this profession. It's truly limitless what you can do.
@@halheavyduty sadly in scandinavia. but if i one day swing by your country i would love to come by the show and say hey if you wouldnt mind btw going to upload a small video with some short clips on some of the stuff i have worked on that i got to film ( its not much but is should give some idea of the stuff i have done that is the larger size. sadly dont have video of the small stuff i have done )
It only happens on that first eccentric pass. After that he’s solid as a rock. Those toolposts and holders are made of a granite-like ultra hardened material, so it’s unlikely they’ll get damaged. We had to machine one recently, and it was literally diamond tough. Had to use ceramics to cut it! Great question though.
It's a product called HOLEMAKER from ITM. I've found it to be great. Doesnt smell, doesn't go off, prevents rust and doesn't gum up the machines. We use it in all of them now, and haven't seen any reduction in carbide life whatsoever.
Great question. It’s just quicker. We do a lot of mag drilling, including for various components on the bit, but in this case flame cutting is just faster.
I went to my hardware store to check and indeed they did not have any three-meter bits in stock. They're imperial, maybe I should have asked for it in yards...
I think that your electricity supplier certainly notices whenever you start a shift. All of those lathes and welders drawing copious amounts of Amps must put a lot of draw on the supply system! I strongly suspect that your electricity bill would be monthly and horrendous! 😮 I don't play with anything anywhere near as big. I haven't actually been doing much in the way of engineering related work for a while. 😢 Mark from Melbourne Australia 🇦🇺
Man you’re spot on! I’m surprised the whole town’s lights don’t dim when the Hulk hits 400rpm 🤣 Lucky we have the entire roof covered in solar panels - which is bloody awesome. We only machine during the day, it’s paid for itself about 5 times over.
@@halheavyduty cfa rig mate no where as deep as this massive thing was only 50 metres the hole was for a ram to push and pull a elevator it was a home built rig made out of a 30 tone digger and a crane boom
That's not a drill, THIS is a drill. What sort of mine is this hole going to be a vent for? Presumably it's 1 one of many precious metals that's mine in central Qld.
I didn't know that they did underground coal mining in central Qld. I thought/assumed that it was all open cut. Blackwater is actually the only coal mine I've seen up that way and that was just before emergency landing on the highway many years ago between Blackwater and Comet. On an entirely separate note it's stupidly hard to work out your business name and location as I couldn't see it linked anywhere and a quick google search didn't enlighten me either.
You could donate those chonky chips to one of those youtube channels that makes knifes and other tools by forging together random stuff. Got enough of it...
If you know of one in Australia that wants to make a knife out of KONG shrapnel, I'd totally donate. That'd be bloody cool to watch actually! Great idea.

Love it! Can’t wait to see the drill bit in action.
Cheers Jack. Me too!
Love it, i can only imagine a workday there and it's putting a smile on my face. Question, are you heating the flanges up once they are on the big tubes so that there's no gaps when you finally weld it to ensure the strongest bond between the two parts?
I genuinely look forward to work every day. I feel really fortunate to have found something I just wake up and can’t wait to get stuck into.
We preheat the material so they don’t crack during welding. If you don’t get the flanges heated to the correct temperature, they crack as it cools.
Good one 👍👍👍
Cheers Max! Love your channel good Sir. Endlessly watchable.
Like your speeds and feeds
Cheers mate 👊👍
Your channel looks great video looks awesome. Content even better. I will subscribe.❤❤ live from NY😊
Thanks a bunch for the kind feedback! A big hello from halfway across the world ✌️
Have you considered drilling and tapping 2 holes at the rear of the kong head for stability? You could have threaded rods will a ball bearing pressed into the end and screw them in enough so they roll on the machined surface you have just cut. So they should roll pretty smooth but give additional support opposite to the cutting head. And each paas, just screw them out to the next distance and lock nut them there.
Interesting concept! The plan is to fire up Kong big brother (Godzilla) and use him instead. It’s a much more rigid bar… and the interrupted cuts don’t even make it move.
A bloody weapon.
Very clover idea though. I like your thinking Chris.
@@halheavyduty i also thought a triangular steady rest or 2 would be good for the long shafts with smaller diameters for the same reason. if you have them slide on the boring bar you could have a central shaft so they roll on the inside where your outer steady rest sits again for stability.
Deep boring definitely presents it challenges. I havent invested in a long anti vibration bar yet, but I suspect we might need to. Fortunately, due the hole size I can just keep making fatter bars haha.
More good machining Matt. It is always best to try and take a full depth cut so the insert is not running in and out of the mill scale as that will just take the edge off the insert very quickly. Great looking rig and will be looking forward to seeing it in action. Cheers Ian
Cheers Ian. Yep, agreed 100%. If you go lighter on the cut it runs way way worse. Just go full depth, buckle up and give old Kong a workout haha.
I cant wait to see the big rig in action too!
Seeing a giant boring bar like Kong deflecting like that is crazy also getting machining time from 6 hours down to 4 is insane also aren’t you tempted to drink the lathe juice looks amazing also how long do you run a tool until you change the cutting edge on a insert also I thought Kong was giant but now Godzilla that like stuff Curtis will do with his 1 meter boring bar it was I think
It’s wild on the super heavy cuts! But man it makes the sweetest sound as it chomps away.
I can’t wait to give Godzilla a proper trial in his new setup. That bar is rigid AF and just loves heavy cuts.
@@halheavyduty our biggest boring bar has a diameter of 29mm and uses wnmg inserts it’s a beast
Haha. I love WNMG inserts. Def my go to.
Love it. Name him Little Kong, the 29mm WNMG.
unbelievable. must take some power to drive a drill that diameter. hopefully we get to see it in action!
It’ll definitely be featured in an upcoming video.
I fully intend on releasing “The Kraken” this month.
cool!, patiently waiting
Won't be long. There's a big 500kg billet of steel sitting outside on a pallet that has a date with the Kraken & Godzilla. Cant wait to get into that one!
Great to see another Aussie machining channel! I'm curious about that red coolant, I've only ever seen water/oil mix used - which appears white. What is that coolant?
Cheers mate. The coolant is called HOLEMAKER (by ITM). It's a fairly standard cutting fluid, but it suits what we do really well. Much better than soluble oils in my opinion. It doenst go off and seems to do the job pretty well.
Amazing work.
Thank you
Wow, BIG is an understatement! Love this. Is this planned hole for oil drilling or some type of construction?
It’s to be used for underground mining ventilation and rescue / safety holes.
This is going to be a MONSTER can you tell me what is going to drive this on the drill rig?
You’re not wrong there mate. It’ll be the biggest rig in the fleet by far once it’s finished.
The drill bit is powered by a custom built hydraulic top head drive. It’s enormous and weighs about 5 tonnes!
Is this bit gor a revers circulation drilling Rig? Impressive
Well spotted. It’s an air RC drill. Custom rods & bit. We’re pretty sure it’ll be one of the largest of its kind when fully operational.
There are large raise bore & mud RC machines out there, but we had to build it custom because we couldn’t find an air setup big enough.
First time watcher and diff a new subscriber. Very cool to see this wild scale of machining. What's the need for a hole 3M dia? And what happens at 250m deep, which is crazy stupid for that dia. but 250m deep by itself is nothing so special. Somebody should film the drilling process as I'm sure everything involved will have to be totally nuts. I'm looking forward following along. Thanks for doing this, and here's hoping for success. Nice that CEE has a great number of followers; you're next!
Ventilation shafts for underground mines. It will drill the holes in 1 shot.
Thanks for the kind feedback mate. Yeah, so the holes are intended for underground mining saftey / ventilation shafts.
The major advantage of this style of drilling is that it uses reverse circulation air, rather than mud - and drills from the surface to depth (as opposed to raise bore methods).
There's bigger drills out there, but none that drill with this style of tech.
PS It'll all be getting caught on camera. We're documenting the entire journey, as this is the biggest (and most custom) project we've ever undertaken. It's bloody wild.
Hey, did you make custom steady covers for all diameters you work on? Notice a nice close fit. Hell we are lucky to cover rollers with so many different diameters, we just re use whatever laying around to protect rollers from chips
I made them for cutting the big HAL316 threads, and will probably make a bunch of sets in the future
It works really well, and makes a big difference when you’ve gotta work close to the steady.
STREWTH. 😳👍❤️
🤣👊👌
You guys hiring I would move to Australia lol
We def will be in the future bro. What kind of work / where are you now?
Great vid mate - I have to ask - what are they drilling for??
They will be used for ventilation in the underground mining industry throughout Qld (and likely the rest of Australia)
You are going to tell me. Why the wobble?
I sat there with my mouth half open. Thank you for showing us what you do.
(Nothing to do with the show) Matt I think that you are proud of your beard, I can see that you go to a lot of trouble looking after it. It looks good.
The wobble only happens on the very first pass. The material isn’t totally round inside, so the cut depth varies as it machines it out.
One side is 4mm… the other is about 8mm… hence the “wobble”
The old beard has gone full bushranger as of late. My barber just retired and I haven’t had time to chase another one yet 🤣
Appreciate the comment Colin 👊
@@halheavyduty My dentist retired a few years ago. I haven't forgiven him yet.
🤣🤣🤣
Truth be known the beard is 90% swarf, 3% rust and the rest, that good 'ol 'red dirt' love ya work guys. Keep on keeping on!
matt love how this is growing, keeping me on the edge of my seat. huge engineering.whats it being welded with, looks like a metal cored wir?
Cheers Pete! Yeah, I think they’re using a mig welder to fabricate it after all the preheating.
It’s a beast of a welder with a serious duty cycle!
Thanks for the diversified content and the peek into your fab shop. While I do enjoy the footage of your jeweler's lathe (did you really say the spindle bore was 320 mm?), the rest of the operation may be more interesting. BTW, the Turkish Hydraulic Cylinder Factory channel has some recent videos with a truly monstrous cross slide boring bar.
I’ll have to check that channel out! Sounds super interesting.
Yep. The Hulk is an 11 tonne monster with a 320 spindle bore. Each chuck weighs about 300kg.
It’s basically a gym workout to operate it. We love the big green machine 🤣
Like all ya videos just great watching this big stuff being done the n the how to get it done i now only play around in my shed doing mostly of all things gun smithing as being Forced into retirement from bad knee to loosing the battle and having it removed makes getting around a hole diferent ball game
This build is Epic to say least
But my prediction is is first up use its goner break some thing this is a massive Drill for sure can only emadgine the power to get it to drill a hole will be very good to see it drill for sure after all the hours of swet n tears to get to this stage good on you and your team major Effort all round
Big Cheers
Ps you say central Queensland would that be in the Mackay Emerald region
Cheers mate! I sure hope nothing too critical let’s go on the maiden voyage.
We’ll be naming the rig THE TITANIC if it does hahaha
Close! We are based just outside Rockhampton
@@halheavyduty will be a great day to see this drill in action i don't think the drill will give i think the rig driving it will
Just out of Rockhampton great place i grew up there so its home for me all thow live farther north in Townsville
Cheers thanks for the reply
That’s awesome! Small world my friend. I live just outside town and I really love it here. Have lived a bunch of places, but this is home for sure
Fot that heavy turning you should probably change the type of tool holder, build your own that can handle the loads.
Totally agreed. We are right in the process of building a super sturdy cross slide boring bar / drill holder.
The toolposts we have are fine for external turning and shallow boring, but not for heavy duty deep boring a drilling.
Fun project. Should have it up and running next week
tip on rebrazing the PCDs in them pilots... dont preheat the carbide ones by shoving an oxy up the inside. how i always did the steel body ones.
client just shrugged... "meh, got it cheap second hand... worth a shot!"
Good tip, and I agree 100%
Will you put a video of this drill rig running or not?
My old timer friend had a business here in Alaska and he had two Hughes drills that would do 3 m holes, but he never had bits to do that big.
I’m a machinist do you like that coolant you’re using? Does it ever break down or separate or coagulate cause gum up on the machines? What brand of coolant is it? you talked about it a few a month or two ago I didn’t write it down. I’m interested in trying that coolant .
We will definitely be doing a full video of it in action once it all comes together.
The deadline is late August / Early September… hence why we are round the clock full steam ahead with it all.
The coolant is called HOLEMAKER. I love the stuff. No residue, no gumming up of machines, doesn’t separate and never goes off.
We haven’t noticed any decrease in carbide performance, and it has excellent anti rust properties.
Question, what would that drill be digging for? water works? something ore mine related?
Excellent question.
It’ll be used for large ventilation and safety rescue holes in underground mining.
@@halheavyduty you should mention that as I'm sure most of us have no clue why you need such a big ass hole in the ground other than bragging rights ;)
I thought I did…
But there were a few takes and I honestly can’t remember if it made it to the final edit 🤣
I’ll make sure it gets mentioned next time for sure.
Whatever it’s for… fark that’s gonna be one big hole 🤣
5:39 i see that you guys use what we call "land bridges" ( at least the places i been ) and i clearly prefer them over the rubber mats. though i like mine with only 3 underline pens instead of 5. so there is some more flex inbetween the the underline pens. but each there own i guess
reminds me. i did see a nefty trick to line up tools and parts with a hole/ round feature. you take a round wireless camera in the spindle/chuck and spin it at somewhere between 10 and 110 rpm's and when the round feature/ hole dont jump around on the screen anymore you know that it is exactly on center of the spindle/chuck ( like if you have a small drill in the tool post. you need to be every precise and both hight/centerline but also in X. you then take a cheep wireless microscope. put it in the chock and spin it around. if its not standing still your not in center and have to go up or down in the toolholder or side to side in X. or if you setup a workpeace in the mill and you have to drill a hole down inside another hole that was already there. you put that microschope in a toolholder and spin it on till the hole in the part stands still on the screen. and you dead center in the hole )
im planing to try that same methode on a normal toolholder for the tool post and see how well it works for just setting the tool at perfect tool high in the toolpost ( i let you know when i tried and how well it works )
Definitely let me know how it goes! Interesting method indeed. I love the creative ideas that people invent to solve problems in this profession. It's truly limitless what you can do.
@@halheavyduty agree
Where are you located mate?
@@halheavyduty sadly in scandinavia. but if i one day swing by your country i would love to come by the show and say hey if you wouldnt mind
btw going to upload a small video with some short clips on some of the stuff i have worked on that i got to film ( its not much but is should give some idea of the stuff i have done that is the larger size. sadly dont have video of the small stuff i have done )
Please tag me in it when you upload it! Id love to see what you;ve been working on.
Should check out Kennametal FIX 8...can take serious DOC on those OD cuts @ serious FPR
Thanks for the recommendation. I’ll check it out Monday. Much appreciated.

I think I’ve seen that one. Some serious DOC and they look bloody sturdy.
Will be investigating the option today. Thanks again for the suggestion mate
I like the Chinese work boots in the workshop and bring back the BEERS in the workshop after a hard long day at work
We are 100% old school. I don’t think the 80s ever left us 🤣
What is a 3m by 250m deep hole needed for?
Ventilation / rescue shafts for underground coal mines (and other applications no doubt once people realise it can be done like this)
Have you looked at Prime Turning By Sandvik?
I haven’t, no. Sounds like I should?
Ver interesting I hope you will tell us what that drill is for
yes, are these for ventilation raises for an underground coal mine?
Exactly!
Is there any concern that the constant flexing that "Kong" causes could damage the tool holder?
It will definately damage the tool post if they don't stop that movement completely.
It only happens on that first eccentric pass. After that he’s solid as a rock.
Those toolposts and holders are made of a granite-like ultra hardened material, so it’s unlikely they’ll get damaged.
We had to machine one recently, and it was literally diamond tough. Had to use ceramics to cut it!
Great question though.
WHICH CUTTING OIL ARE YOU USING RIGHT NOW??? IT IS GOOD OR NOT????
It's a product called HOLEMAKER from ITM. I've found it to be great. Doesnt smell, doesn't go off, prevents rust and doesn't gum up the machines. We use it in all of them now, and haven't seen any reduction in carbide life whatsoever.
Ken Huge.
Ken Oath 💯👊
Why burn the holes when u can mag drill ( hougan) them
Great question.
It’s just quicker. We do a lot of mag drilling, including for various components on the bit, but in this case flame cutting is just faster.
Мне нравится,! подписался, из России.
Thank you! Big hello from the other side of the world 👊
What is the purpose of this hole(s)that they are drilling?
Currently for underground mining ventilation/ rescue shafts
👌 wow
👊
I went to my hardware store to check and indeed they did not have any three-meter bits in stock. They're imperial, maybe I should have asked for it in yards...
🤣🤣🤣🤘
6:22, 40 amps at how many volts? And 3phase?
3 Phase. I’ll have to check the Volts
KONG needs a jack leg .
Hahaha. He totally does. Got a workout this week!
sir what happen if no preheating before/after welding?
The welds crack upon cooling. Especially with alloy metals.
@@halheavyduty thank you for ypur information sir
Not a problem at all.
I think that your electricity supplier certainly notices whenever you start a shift. All of those lathes and welders drawing copious amounts of Amps must put a lot of draw on the supply system! I strongly suspect that your electricity bill would be monthly and horrendous! 😮
I don't play with anything anywhere near as big. I haven't actually been doing much in the way of engineering related work for a while. 😢
Mark from Melbourne Australia 🇦🇺
Man you’re spot on! I’m surprised the whole town’s lights don’t dim when the Hulk hits 400rpm 🤣
Lucky we have the entire roof covered in solar panels - which is bloody awesome. We only machine during the day, it’s paid for itself about 5 times over.
That's a massive drill biggest I have drilled was 1000mm
It’s gonna be wild.
Dude well done by the way. Not many people have drilled a 1m hole. What kind of rig were you using??
@@halheavyduty cfa rig mate no where as deep as this massive thing was only 50 metres the hole was for a ram to push and pull a elevator it was a home built rig made out of a 30 tone digger and a crane boom
Nice!
That's not a drill, THIS is a drill.
What sort of mine is this hole going to be a vent for? Presumably it's 1 one of many precious metals that's mine in central Qld.
You’re bang on Alan. It’s for ventilation (and rescue / emergency) shafts for underground mining - mostly coal.
I didn't know that they did underground coal mining in central Qld. I thought/assumed that it was all open cut. Blackwater is actually the only coal mine I've seen up that way and that was just before emergency landing on the highway many years ago between Blackwater and Comet.
On an entirely separate note it's stupidly hard to work out your business name and location as I couldn't see it linked anywhere and a quick google search didn't enlighten me either.
The drilling company is DEPCO. Hal heavy duty is the machine shop within that business (named after the company founder).
I’m surprised some Canberra politicians haven’t turned up claiming responsibility for all this skilled workmanship….
🤣🤣🤣
stupid question whats baker locked?
Great question.
It like a Liquid Metal. A very heavy duty form of LocTite specific for drill rod applications like this.
