The Largest Drill Thread We've Machined in 60 Years (It's Literally Off The Charts!)
Вставка
- Опубліковано 6 жов 2024
- We just broke our own 60 year record with a completely custom thread for drill rods that will end up weighing a TON.
Welcome to HAL Heavy Duty Machining Australia, a real live Aussie machine shop based in Central Queensland that specialises in the drilling industry. In short, we fix stuff that drillers break... and make all the heavy duty custom gear they need to get the job done.
In this video we machine up a completely custom thread for our upcoming Megadrill project - a VLD (very large diameter) rig capable of drilling 3.0m diameter hole to depths of 250m!
Due to the incredible torque created, we have to machine completely custom rods that are quite literally off the scale - 40% larger than anything readily commercially available. It dwarfs an 8 5/8 reg (about as big as it gets for standard onshore rigs to my knowledge).
OD is well over 300mm
Thread length is close to 200mm
Can’t share much more specifics as it’s a custom prototype.
It’s definitely a record for the 60 year history of the company (by FAR) and MIGHT just be one of the biggest rod threads machined with the intention of being spun off the back of a road registered drill rig.
No doubt the comments section will light up like a christmas tree if not.
Which is exactly what I want.
I can't find bigger, but if someone knows of it, PLEASE let me know. No claims of an actual world record in this video... we just don't know for sure. Yet.
Enjoy, and thanks for tuning in.
Just discovered your channel. Great machining stuff. Don't let anyone turn you down by comparing to another channels like Bomber from Florida, Cutter from Australia, Infinite Precision Man from Germany. Remember it's your channel, your shop, your rules. We like them because they are different and you should be yourself too. All the best and keep up the good work.
What a wonderful comment.
I couldn’t agree more.
My goal is to be as authentic as possible, share the interesting stuff we get up to, and God willing… add a little value to the conversation.
I just love machining, and feel really fortunate to do what I do.
Appreciate the comment mate.
Wise words
I thought it would be boring, turned out to be nuts.
Haha. Cheers mate
aren you dirty mind ? :D machinist jokes after 22pm :D
🤣👌👊
HA! He said 'boring'. LOL!
💯🤣
I really like your work. You're not acting like you're the best. You work like Oliver on Snowball Engineering. He's also very talented and hard-working. You both do different types of jobs, but also show the same considerations for your customers and audience. Great job making something totally new from scratch.
Thanks mate, really appreciate the kind feedback.
Just doing my best to learn and keep getting a bit better. The channel has been really helpful - lots of really insightful comments from clearly experienced machinists each week give me plenty of ideas on how to improve.
I’ll have to check out Snowball engineering. I don’t think I’ve seen his stuff yet! Thanks for the suggestion
First time watching your channel, Awesome work! I´m an Industrial engineer from El Salvador, trying to expand my knowledge in machining and channels likes Kurtis and yours are a god send for that purpose. Keep it up, I´ll be waiting for more videos.
That’s fantastic mate. I met some wonderful people from El Salvador when I was living in Argentina.
Glad you’re getting into it all. Machining is such an interesting profession to be part of.
Yeah man, you’ll learn heaps off Kurtis’ channel. That guy knows his stuff.
I am novice home hobbyist machinist, I got my first lathe 18 months ago (1949 South Bend 9A ) and can appreciate what you do - flat belts limit most of my cuts to ten thousandths or less! Keep the vids coming❤
Nice work! Some of the little old lathes out there are great fun to work on
@@halheavyduty after a career in law enforcement, and several years of small business ownership, there is just something about making big pieces of metal into little pieces of metal… 🤣😂🤣
It’s addictive once you get started hey!
@@halheavyduty it is therapy…
Amen to that. Agreed 100%
Kong is big but I hate to tell you, Kurtis from Down Under at Cutting Edge Engineering has it beat by 3 miles. . Specifically, it weights 209.5 lbs or 95 Kilo's and is 125 MM (4.9 inch) bar and 1100 MM long (3.6 Ft) with 900 MM (2.9Ft) of reach. . It's King Kong of boring bars. . Has to use an overhead crane to get it off the floor. . It's so big it's funny.
I watched him make that bar on one of his videos. It’s awesome!
Kurtis does some great work and his channel is the gold standard as far as I’m concerned.
Thanks for the comment 👊
I have seen that as well but don't bet on it because it's no where near as big as the boring bar I've seen in engineering magazine which was on a big CNC Lathe in Albury,just can't remember the name of the company.
Saw him make it but l haven't seen him use it yet.
There’s some insane gear out there. It’s one of the reasons why I love this profession so much.
It just never gets boring
Pfft!!...Nothing compared to bars used on Horizontal borers(Which you have just described)..but king is a toddler yes!
Love seeing your videos - it takes me back to my younger years working in heavy machining and making proper parts !
I remember making some bespoke couplings for the north sea oil industry here in the UK many moons ago. we didn't have a lathe big enough to make them so we made them on a huge horizontal borer, and had to cut 1800mm diameter acme threads almost 1 meter deep. Much slower than turning but we got the job done and the customer was more than happy !!
Holy crap that’s a big thread! Yeah, there some mega gear on the North Sea oil industry.
Thanks for sharing.
Love it.
I recall as a kid watching my Dad cut 7/8 14 tpi for an old Allis Chalmers Combine. To go next size up cause 3/4 was chewed up. soooo long ago. Thank You for keeping the craft up and running 😉👍❤️
That’s so cool. I have similar memories as a little kid watching my grandad Hal work making drill subs by hand.
Thanks for tuning in mate
I did my Apprenticeship in a Shaft Shop.
All we made All Day was Shafts ???
( what are we making today ??? )
IF you can Turn It.
We made or repaired it.
The business had it's 100 year anniversary when I was working there.
When I first started working there we had a joke running where was most of the Rain ?
Outside or Inside the factory 🙄
Not only that to deal with, the floor had large pieces of timber covering the huge pits where the Flat Belts ran the earlier machines.
The positive of that was, when it Rained the pits would fill up with water ??
The place was huge and so were the Holes in the Roof and Floor ???
Thankfully after I started there with 4 other Apprentices the indoor swimming pools were finally filled in with concrete and they replaced the Hole Roof.
The Old Tradesmen all hated us, because we made the place too comfortable.
( their words, lol )
Adding to that we were the first Apprentices to be hired by this company.
The Lady who pushed us into this place was so proud of herself for what she
accomplished ???
We only found out about the thing with the first Apprentices in the lunch room about 2 weeks after we started.
Trying to find a way to stir up the Tradesmen ( as Apprentices are only good for ?? )
One of the Apprentices called out to the Tradesmen asking ...
Have you ever had any Apprentices working here ?
The Old Tradesmen started laughing and replied..
Don't wantem and don't need em.
The Apprentice who asked the question only lasted till the end of the first month because the Trades wouldn't teach us anything.
We were only the go for boys ( go for this, go for that or maybe hold this ?? )
Thankfully the same week as the other Apprentice left they suddenly started teaching us everything.
They were Amazing to work with after that first month.
We all learnt So Much from these guys.
It was a tough job.
We learnt the hard way to do it the easy way.
( something they always, kept telling us )
Apologizes for the Long Comment.
I just wanted to highlight the Tradesmen who not only taught us Skills.
But how to become Men too👍👍
I read it all! Great comment. Sounds like a bloody interesting workspace though.
Old tradesmen make good young men. We have a few young guys in the shop and they’re great apprentices.
It’s very rewarding to see their skilllset and confidence grow. We focus on three things
1) Have A Great artifice
2) Be Coachable
3) Work hard and be patient.
Good things take time.
Thanks again for the wonderful comment. Really appreciate it
Ah yes, the forbidden pink lemonade 👌🏻
I’m sticking with Pink Panther juice 🤣
Just ask Jim Jones !
I suspect that drinking our forbidden pink lemonade / Panther juice might produce Jonestown style results if you drank it 🤣
I just found your channel by coincidence and was immediately catched by your voice and explanation.
Great camera work also! Love it. Greetings from German🙋♂️
Thank you for the kind feedback mate. Glad you enjoyed the video!
People always are shocked by the big stuff. I’ve only ever worked in a heavy machining shop so an M580 nut (a samllish for us) isn’t really that big. Great video. Love a shop made tool also.
That’s awesome. Love that you’re doing the heavy stuff brother.
Thanks for the kind feedback. Much appreciated.
@@halheavyduty 💪 keep it up bro
💯👊
"now we gotta cut 30 more of them" 🤣
I know right…
Great to see a guy who loves his job
I really do. Cheers mate
Talk to you regularly great to see my tooling working
Your extra long drill sub was the test material in the HTS drill video bro 🤣
Looks beautiful. So very shiny. Can't wait to see part 2 for the other part. . very exciting.
Really happy with how it turned out. Can’t wait to see them screw together in the next video.
Thanks for tuning in 👊💯
Very enjoyable, not boring at all.
🤣👊👌
It's a work of art and science!! So impressive on size and perfection!
Thank you! It’s been one heck of a challenge to get them on point. Nothing like a custom oversized thread to get the brain working…
As a tool and diemaker, I love watching how this heavy work is done. Much of my work had to be verified to ensure the part was within specification. In this case(huge internal thread), how would you verify the threads you have cut? Do you have a part that you can test the thread fit against or a Go/No-Go gage? How do you measure the pitch diameter? Love the videos.
Thank you. These are all just the prototypes under development. Once we are 100% happy with them, all the testing checks and balances will be created accordingly to ensure they’re consistent.
Great question.
It's all a bit bigger than the stuff I make, I use a Simtek boring bar that fits easily into the bore of a 1.8 mm mmWave feedhorn. One of my upcoming jobs needs an even smaller tapered bore, only 800 micrometres diameter. Great to see some proper-sized machining for a change. I'd be interested to see what you do about metrology and QA inspection in a future vid. Can't exactly buy a go/no-go gauge for that thread! Totally with you on the nerdy side of CNC, I've been coding since 1972 and recently treated myself to a new SYIL X5 mill. Huge fun programming what is effectively a two-ton killer robot!
Holy wow! Micro stuff like that would do my head in. Mega respect to all the precision machinists out there.
Nice work re the mill. I haven’t had any CNC milling experience yet, as we just don’t get enough work to warrant buying one.
I’d love to… but it’d spend 95% of its life as a 4 tonne ornament.
Wow. You’ve clearly got some experience in the field mate. Well done!
Just ran across your channel. Very nice and interesting video, and I like your attitude. Nobody anywhere knows it all. As long as we keep learning, we keep growing. Cheers!
Thanks mate!
I find that the more you know… the more you realise you DONT know 🤣
Especially in machining. Half the reason why it’s so fun for the endlessly curious kind of person.
I've machined 8" Drill Joints years ago,
But nothing close to that beast !
👏👏👏
Nice work Mark! We very rarely go past 7 5/8 Reg for the rest of the rigs… so if you cut 8” connections you were def at the max end of it.
This thread is a real outlier… we just had to create it to handle the crazy torque when cutting a 3m diameter hole.
Thanks for commenting and for tuning in. Appreciate it brother 👊
Only recently found your channel. Great to see an Aussie Machine shop showing their workmanship to the World 👍
Where in Qld are you guys based ?
Up in Rockhampton. Thanks for the kind feedback too. This big rig has really challenged our capacity to the max. Even the two big lathes (Hal & the Hulk) are getting maxxed out at the moment.
Nothing like a good challenging project to keep you sharp.
Love the videos, not to many ads, so i watch till the end, Not GREEDY LIKE SOME. no bullshit just great content. Thanks. Look forward to next week.
Thanks Phil. Glad you enjoyed it
At my last job we used solid brake tube for coolant jets and adapted it for the machine, you could run/bolt a line/s along your kong bar and bent it to keep the coolant onto the cutting edge. Ours was 6mm and we would run a die along it to thread into a bung or braise it on.
That’s a bloody great idea! Thank you. I might just give Kong an upgrade when we aren’t flat out.
Love it. Very clever.
@@halheavyduty probably bolt a manifold onto the side of the bar to put your quick change fitting on. And just braise/solder the brakeline in it.
I'm glad i could offer a worthwhile suggestion.
Much appreciated mate. Thanks again
That is serious machining, to have a steady rest on a work piece that short.
Yep. It just lets me do heavier cuts and stops vibration during the threading process.
loving this, cheers from the other Sunshine State, Florida USA...Paulie
Cheers brother. You’ve been here since the very start and I appreciate your support.
All the way from the other sunshine state 👊
Nice thread, seems a good surface finish, I have now only a 4" lathe. I do boring bars on the opposite site, so the insert faces down. doing it that way, my maschine tends to spiraling and blocking. Biggest i made with this lathe was 60 mm dia, 0.5mm per rev. (around 2 1/2", 0,02" per rev) in early 80 i made a screw, used as pylon with 3.5m dia and 25m long.. 6m thread lenght, pitch 4 inches. 40 tons if i remember correct. took an whole day for fit testing the nut. but it fits smooth :-)
Nice work! Nothing more satisfying when it finally screws up properly.
Those Alpha's look great in the background mate.
Big fan of them brother. Thanks for all your help setting them up. Very grateful for all the support - especially considering how remote we are.
Hey dude new subscriber here. Gotta say I really enjoy your content and seeing someone passionate sharing makes it even better. It’s nice to see all the machine work in Australia like cutting edge engineering if you heard of him.
Keep up the good work
Best regards from Switzerland
Welcome to the channel brother, and thanks for the kind feedback.
CEE is excellent. Kurtis & Karen are about as good as it gets when it comes to machining channel in my humble opinion.
Love watching his stuff. Guy is a genius on the manual machines
Always a good rule of thumb to bring your hand or some similar into the shot to scale size of the stock
Great idea. I’ll be sure to do that in future videos
Rule of Hand more like it
@@madmodder123 10-4
👊🤣
The only thread I know of that is larger is 8” and 10” BECO thread; they can be cut as 273mm or 343mm O.D. Invented by Bucyrus for blast hole drilling rods. I manufacturer these rods for larger diameter DTH drills. The only other place I’ve seen them used are on Atlas Copco/Epiroc Pit Viper drills. I have custom inserts made to the thread form.
Yeah wow. That’s pretty huge. My brother is a blast hole driller and they use some pretty big connections there too.
I’ll check out the thread you mentioned. Sounds bloody enormous.
Really appreciate the comment.
Great vid, it really does make 8 1/2-inch Reg look so small and next is the pin 😀. I had a laugh😆 about the comments on the size of Kong and Curti's boring bar, everything is relative to the size of the lathe you have and the work you perform. Where I work our largest boring bar is a Sandvik anti vibe bar and it is 200mm (8 inch) in diameter and has a max working length of 2 meters (79 inches) and that doesn't include the rest of the bar held in the tool holder mounted on the cross slide, so that makes it over 3 meters long and it's still not long enough as we have to turn the component around and bore it from the other side as well.
I know right 🤣
Bro that bar sounds wild. I didn’t realise that Sandvik made a bar that big. The things I’m learning from these comments is wonderful I’ve gotta say.
What kind of work do you do?
@@halheavyduty We support the mining industry, mainly hydraulic cylinders.
Nice. Heavy gear when you get into mining hydraulics. Some of the lathes they use are monsters on the big cylinders.
Don't be running yourself down m8, from what I see you're doing fantastic work with the machinery you have.
Thanks for the kind feedback mate. Appreciate it
Very cool. I love watching machining and custom metal work. Would have been really cool to see some pics of the machine that its for.
Cheers mate. Yep, we’ll be showing all the progress - the big rig is still under construction.
Can’t wait to show it in action drilling using all the custom gear we’re spending the next 6 months constructing.
Great to see another machining channel, don't want to deflate your boat, today i cut a 26" 10 tpi thead in 316 stainless . And that's only a small one . Good job keep those vids coming. Cheers
Thats awesome bro! Love it.
I’m endlessly curious about all the great machining projects out there.
26” is massive.
Great work.
What was the thread for??
@@halheavyduty it' was a body seat ring for a 750 mm check valve.
👌👊
That's a stout bar for certain but the coolant shows the vibration still. There's you, CEE, then the guys that did the boring on battleship 16 inch barrels. ;) Heard from some local fellers that they would ride the compound and a single pass was 8 hours.
I’d love to have seen how they did them! Some insane lost skillsets out there.
We are just finishing our cross slide holder for Kong’s big brother…
Should be an absolute monster
@@halheavyduty I agree, some of those big machines from Arsenal row in watertown ma, I heard they had a lathe with a 100' table, would love to have seen that in operation.
Me too. Me too 💯
I'm not a machinist. Nothing I've seen on This Old Tony prepared me for that depth of cut. Definitely not some home-gamer mini lathe.
Cheers mate. Kong is a pretty fun little bar to run. Just loves heavy cuts.
You know it's serious when the tool you whack out got it's name scribed on it! :D
🤣💯
Impressive!!! I do some small manual turning once in a while for maintenance/repair at work. Small question, why not modify Kong to have thru coolant? It may be a wee challenge, but well worth it in the long run.
Great question.
To save time I’ll probably create a new 63mm bar with a WNMG insert in the near future. They just seem to cut better - especially on the finishing passes. That, and the inserts cost a fraction of the big 16mm CNMG ones.
I don’t have the horsepower to maximise Kongs pontential anyway, and through coolant on that bar will actually be pretty difficult to do now.
Kong has a bigger brother (an 83mm bar we call Godzilla) that’ll be featured in a future video.
Godzilla has through coolant and can bore out holes 650mm deep.
Kong’s limit is about 350.
Im an auto spark and did a few rewires on drills over the years. The size of the gear on some of the rigs blew my mind. I cant even imagine the rig thats gonna run that
Nice one!
Yeah, it’ll be a wild setup that’s for sure
Thank you for the video and explanation 👍
Most welcome! Thanks for tuning in 👊
The thread is an interesting byproduct of all the slinky manufacturing being done.
We have quite the collection now 🤣
Hi Great video, be great to see a wider shot of the machine included whilst its machining. It looks like a Harrison alpha. I bought my first Alpha in 1996 an Alpha 400 so just a small shop lathe with a 55mm spindle bore. Loved that machine, ran it for 10 years and had to part with it sadly. ventually bought another secomd hand 1997 model i rebuilt in 2012 and use hard every day , great for one offs and repair work as you get best of both worlds with manual/cnc combined. look forward to seeing more great content from you
Well spotted! We have two Harrison Alphas and I love working on them.
Exactly as you said - great for small run parts and good for repairs in alpha mode.
We have a 1560 and a 1760 (the one in this video).
Will be sure to get a bit more of them in upcoming videos. Thanks for the idea.
Just discovered your channel. Great to watch. Are my ears playing tricks; it sounds like the lathe speeds up on the facing cuts to maintain a constant cut speed?
Thank you.
Yes, you heard correctly. The Colchester Alpha lathes have constant surface speed (CSS) as a setting.
Makes for a nicer finish on face cuts, and generally improves tool life.
I like how the chips off Kong are so heavy they just sit at the bottom of the bore. Too heavy to spin around and foul up your cut. Also like the rack for your tool holders. Neat set up.
Cheers mate. Yeah it’s a really fun tool to run. Going to do a cut depth testing video at some point.
We had him cranked up to 8mm cuts today and the chips were insane.
Little weapon blasted through it.
Thanks for the feedback re the tool racks too. It def makes working on a CNC like ours way more efficient.
I machined part of the Large Hadron Collider. Eight metre long six hundred millimetre tubes in stainless steel.
Dude that’s awesome. The LHC is one of the biggest man made structures there is.
Very cool.
This is pretty cool. There is no API standard for that thread I would assume. (is there a world standard, DIN I suppose, now for drill threads?) I am also going out on a limb and say it was engineered along those lines, however I didn't notice much taper. . I am an former water well driller and we usually used threaded connections around the 3" range. We did have a few tools that subbed on to the drill stem with the 8 5/8 thread and it was pretty large stuff especially for our application. thus seldom used. Looking forward to the pin. Cheers from the Northeast USA.
Hey Warren,
Thanks for the comment mate. The big thread as sort of evolved over time. 8 5/8 reg was the highest we could find, but it wasn’t strong enough to handle the immense torque loads.
There was another thread we had before this one, and it’s held up great for up to 1.8m
But we are entering pretty crazy territory now… so fingers crossed it holds up.
Yeah, most of our water drilling threads are around the 3” range as well, although the big artesian deep wells go larger.
I betting money that there’s oil well / deep sea rod connections that make this one look like a kids toy… but haven’t been able to find them yet.
Fascinating stuff. Thanks for the great comment brother 👊
Just gotta love the incanink! Lotsa talented people out there. Some are really good when it comes to offering up sound advice.
Yeah big stuff always attracts interest.
Interesting vid. Don't see a lot of Aussie stuff, so all good.
In small scale manufacturing myself, but vastly different field.
It’s amazing the diversity in machining. I find it all so interesting.
Thanks for the comment, and for tuning in 👊
Bore / Core sampling very deep , outer being's would use larger on scale , keep up the good work
Yeah, from the comments there some pretty big blasthole gear out there too. Going to research it all some more.
Fascinating what’s out there!
Thanks for letting me know. Appreciate it mate 👊
One question. Why no through cooling in Kong?
Btw if you can prevent or have a guy with some fire suppression gear ready at the machine. Then nothing beats running straight up oil ( like the strub's vulcan futura cf2915 ) and run it as a as close to room temp as possible would be optimal ( witch can easily be done by running it through a normal pc/car radiator/ condenser with a fan taped to it before going through the nosel out to the part. We did it and it worked surprisingly well )
Interesting concept re straight up oil. Haven’t heard that one before. Sounds like you’ve got some solid machining experience brother 👊
The Kong bar was all welded up like that when I took over, so I’ve just left him as a solid bar. Ideally if I made it from scratch, I’d go for through coolant for sure.
@@halheavyduty cant you just bor through the weld and use the hole that is in the head already ? ( if there is one that is ) or brac a slim copper tube going down the side of the tool aimed at the insert ( basicly makeing a non through cooling into a "through" cooling )
if you want i could show you a few pics and short video clips of what i have done if machining things
Nice thread ! Nice plumbing on the coolant lines too. Should I ask how man checks such a part before unchucking ?
Thank you! For the production run we are using the testers that are cut in this video to check before removing.
We also check measurements along the way - including bore size & thread depth.
i got to see the aftermath of something this size letting go in a hole when they bought various bits into the shop...
wooo!
2km of 12" drill snagged and tangled like a pretzel. (back reaming, horizontal boring) would have loved to have been on site... then again, glad i wasnt...
Fark. What a shitshow that would have been!
Hi Mate, I did my apprenticeship and worked as a 1st class Machinist at Boart Longyear in Adelaide during the late 80's and throughout the 90's/2000's and cut some pretty big threads especially API threads! Why do people call your coolant the forbidden pink lemonade?
We run a brand called Holemaker and honestly it does a great job considering what our basic needs are.
Someone last week commented “omg you ground up the pink panther” and I lost it laughing. Now I can’t get the bloody theme song out of my head.
You would have cut some big threads at Boart Longyear. Any standard Commerical sizes bigger than 8 5/8 reg that youre aware of??
@@halheavyduty Thanks for your reply mate! I cut literally thousands and thousands of HQ,NQ,BQ and AQ, AWJ ,BWJ as well as casing and innertubes as well_ love your videos bro!
Nice! Nothing like machining up a beautiful crossover sub... for them to send it into the ground and destroy it haha
I don’t what the big deal is, the ring on my shaft is exactly the same size as that!
🤣🤣🤣
You ought to get together with Kurtis from Cutting Edge Enginneering - that would be some real fabrication porn !!
Goals for sure.
Kurtis is a top bloke, very talented machinist and has a great channel.
12:23 So that's how slinkys are made!!!
💯 🤣
I have made bigger ACMET thread in smaller holes .. It is hard when there is little space But nice work
I’d love to see videos of it! Have you posted any?? If you haven’t, you totally should.
I’d watch it for sure! 👍
Very nice! I still use a lot of top notch style tools.
I find they’re pretty good. Only two sides per insert is the major downside, but they do the job just fine in my opinion.
@@halheavyduty We also make special profiles with them.
Nice one.
Yeah, I find the blanks really good for that. We grind up a lot for strange once off threads too.
Great Job!!!!!
Thank you 🙏👊
Kong is incredible
He’s a little animal 🦍 .
Definitely bigger bars out there, but he does the job 👊
Damn you're all over the place with the camera, I had to smoke a couple of doobies just to keep from getting seasick
It was like Cloverfield of the machining world 🤣 not even gonna defend the camera work in this one.
Have done my best to make future videos more stable and watchable. Check out the most recent one if you get a chance and let me know if it’s actually any better?
Hard to judge your own work.
Thanks for commenting bro.
Never seen piss like that before. White, green, yellow. Shitty brown colour if it goes rotten, but not red.
Lovely looking thread too. 👍🏻
Hahaha. The old Pink Panther juice. Stuff never goes off
You make excellent videos.
Thanks for the kind words Brad. Very grateful to be able to share what we do.
I find it really interesting work, so glad people out there seem to appreciate it too
Beautiful! Nice work. What do you do for inspection of finished dimensions?
Great question. I’ll be doing a video on it in the next week or so.
We check measurements during machining, check thread depth, and then use a tester to make sure it screws up.
Too big for a go/no go gauge, but our little QC method seems to work well.
Hard when they’re this bloody big.
It so damn heavy.
@@halheavyduty tyvm
Most welcome 👍
That's insane
💯
Think so... anything bigger is likely casing. A go/no-go gauge for this set in the works? Sooner or later, inspection arrives.
That’s what I thought too re size.
Definitely larger casing threads exist 100%… but it’s quite off the charts as far as drill rod connections go. I doesn’t really matter too much, I was just really curious.
Re go/no go. What a great question. Yep, all being developed alongside.
This is just the pilot tester so we can see it in the flesh, so to speak 👍
that answered a question; can you alter the spindle speed to maintain the surface speed (and therefore finish) when taking facing cuts *(hears motor spooling up as it makes the cut)* apparently you can.
Yes, the machine has constant surface speed. Definitely gives a nicer finish, especially on facing.
Hi ,you make nice content, however , i was wondering how do you measure this internal thread ? Do you have a thread gauge or something ? I do some thread milling , like a M162 x 3 or M 184 x 3 ,but at first i make a gauge witch i can meassure with 3 wire measurement to see if the pitch diameter is within tolerance , and then i make the internal thread to slight oversize so it will fit any part of that size any time .
We cut the box first to exact measurements, and use a depth gauge to check thread depth.
The box is then used as the tester for the pin connections.
It’s still a prototype, so once we are happy with it, further testing will be developed to make sure they’re consistent.
Thanks for a great video . Is that a Colchester lathe ?
Well spotted! Sure is. It’s a Colchester Alpha 1760.
have look at Cutting Edge Engineering for his "Large custom made boring bar"
It’s a weapon. I watched Kurtis’ video on that one.
Baby Kong’s got nothing on that bar!
Biggest in the world? What about the drill pipes used on the Glomar Explorer, the ship that raised part of a Russian submarine?
Im almost certain that some of the big offshore stuff makes our thread look like a child’s toy…
And some of the blast hole stuff is similarly sized too.
From what we can tell, it’s the largest RC tool joint there is, but I have no doubt some of the custom deep sea stuff must be bigger.
The comments have been really helpful. It’s off the charts when it comes to standard gear, and much bigger than anything our little shop has done before.
Kong is one beast of a boring bar! Kinda surprised to see it’s not set up with through coolant. Is it a solid bar?
Yeah… I wish it did have through coolant, but it was already set up before I took over running the machine shop.
We just flood it with coolant and it seems to hold up well.
His big brother Godzilla has through coolant thankfully!
Thats not large, just think of the massive cnc and lathes used to make massive ship engines and crankshafts that what you call massive, its like 20 times larger than this stuff, but still very specialised tooling and carbide coated inserts and also the amount of heat treating and tempering that goes on, is insane, plus the coolant your using is it full synthetic or oil based with water, distilled water or ironized water etc. keep it up mate and great content as always.😎🦘👌✌
OMG - That's how Slinkys are made!
💯🤣

Dude, it was pretty risky to pick up the piece like that, the magnet should have been on only one diameter, covering more contact surface. Doing the way you've done you've had like two pairs of points of contact.
I've been told by my ex supervisor (20 odd years ago) to lift it up just a notch from the floor, and purposely hit the piece to see if it would have stayed attached. It's like simulating bumping it on the jaws. You won't want that bad boy to fall from a height, especially in the lathe.
Just an observation and a suggestion. You deal with it however you wanna.
Oh I hear you brother.
Prior to filming I actually had the billet about 6 inches off the ground and literally jumped up and down on it like a kids swing.
Appreciate the comment mate. You’re not wrong in the slightest. I’m going to start banging it with the big bronze hammer as well just to double check.
Excellent suggestion.
@@halheavyduty Hahahaha, pity you didn't film it, it would have been pretty educational. 😂😂
Am glad to hear you've put your whole body weight to test it, I've been thought to stomp it hard.
Thanks for the update, overseas cuz. 😁 (Typing from Italy)
By the way, what metal is that? I'm not sure I've catched it in the video.
I'm absolutely going to film it in the future. Haha. Gold!
What was that he was talking about the nose radius of the finishing cut? Junior machinist here.
Excellent question.
You want to make sure the depth of cut for finishing cuts is larger than the nose radius.
Not a hard rule, but it tends to create a better finish and you still get chips to break.
We run a 0.8 radius on the WNMG, so the finish cut is 1mm deep.
Kong is a 1.2 radius so we do a 1.5mm finish cut usually.
Hope that helps.
Right on, thanks for the reply. I’ve been learning by doing and watching. Just bought a “newer” lathe to replace my old slow one. I enjoy how a person can start to get a feel for the machine and its work. Good luck with the channel, cheers from Canada!
That’s great to hear mate. Well done on the newer lathe.
I hear you re getting familiar with the machines. Always takes a while, but once you get experience on a particular machine it’s like playing with an instrument.
Just a joy to work on some machines.
Cool stuff. Definitely subbed.
Cheers mate!
what is that pinkie juice . :D its like from different world
The pink panther juice is called Holemaker. It works pretty well and is just a standard drilling / cutting fluid
This is what I've been trying to do just 3inch
Nice work. Hope you’re having a win with it. I really enjoy cutting threads. Something mesmerising about it.
Do you just keep threading until it looks done? Curious how you measure the PD
It’s all programmed in, but we have a simple depth gauge to check.
It’s gotta be 100% bang on (well… to 0.1mm at least)
Great question.
CEE will be rock hard watching this 😂
Love his channel. Those two are great
Channelling Crocodile Dundee? That's not a thread, this is a thread
🔪🤣
Good intro🎉
Thank you. Appreciate the kind feedback mate.
Nice work brother !!
Cheers Gavin!
Didn't see you gauge those threads.....must've been too busy watching the pretty pink coolant
Haha. Pink Panther juice for the win.
These are just the pilot threads. We wanted to see the “in the flesh” before committing to a big run. Testing will be developed once we are happy with them.
What is TPI and TPF? Is profile similar to API Regular or Int. Flush? I've cut more than a few (hundred) tubing and casing threads, and many of the Spec 7 (API) tool joints, and there are casing buttresses that are quite a bit bigger, but I think you've got the world beat in tool joints. I'm curious what you're doing about gaging?
Hey mate, great questions.
Unfortunately I can’t share any specific data on the thread as it’s a custom under development.
Similar to the larger API reg threads, with some significant differences though.
I used to make videos for commercial equipment, you have way too many scene change’s and fades, the thread cutting section was quite good in fact the best part of your video as far as watch ability goes.
Take your time with camera movements, nothing turns people off faster than quick shots as it gives them a headache trying to follow the view.
Get a camera tripod for some of the shots it will allow stability and help greatly with close ups.
Don’t zoom too much as you can overdo it.
I see you follow CEE so pay attention to Karens work and how she films Kurtis at work, she is getting very good and her editing is great.
I’ll wait and watch a few more of your videos before subscribing. Cheers.
Hey Peter,
Thank you for taking the time to give that feedback. Highly useful and I fully intend to alter my approach in future videos.
After rewatching, I agree. I’m going to sort a fixture that mounts on the toolpost to get some more consistent video that doesn’t shake.
Please let me know if you can see visible improvements in future videos - and by all means let me know where I can improve.
The goal is growth, and comments like yours are solid gold.
Thanks again mate 👊
Matt
Excellent vid bro
Cheers mate. Appreciate the feedback
"Vid bro" requires a "translate to English" , nice one cobber.
🤣👊👍
7:13 as big as Kong is, why is it not set up for through tool cooling? The current setup could be blocked preventing proper cooling.
Ok, later in the video I saw what I thought was a cooling port and shortly thereafter I saw it in use, why wasn’t it used from the beginning?
Kong is a pretty crude shop made bar that was here when I took over.
Made from solid. I will sort through coolant for him at some stage, but haven’t had a chance yet.
Well spotted. I bloody wish it had through coolant. Fortunately his larger counterpart does…
Kong is a KM63 head.
Bigger bro is KM83 (plumbed)
What kind of coolant is that machine running?
It’s called Holemaker. They were using it when I took over the shop, and from what I can tell it works pretty well.
It’s got good rust prevention properties, doesn’t leave residue (too much) and doesn’t seem to go off.
Do the zip ties dampen vibration on the threader ? Good idea, like rubber bands on boring bars before technology
On longer bars we usually zip tie rubber. It works really well.
We also use zip tied numbers for tool identification. I don’t think the zip ties themselves do much without rubber though
@@halheavyduty yes, I saw that I was kidding but rubber sheet and zip ties is good. I’ve seen others do that. I’ve been milling for a while. Turning to me is more controllable. Where are you all at geographically?
We’re based in Rockhampton, Central Qld.
A 3 metre hole 250mm deep, from the back of a Truck! What ( material) are you drilling into?
We are drilling large diameter ventilation holes for underground mining.
Max size to date has been 1.8m to 270m…
To go further the team had to design a big rig from scratch to do it - including all the rods, drill bits.
The lot.
It’s all one big crazy custom project.
It’ll be drilling into a variety of different types of earth over its lifetime I imagine. Depends on what’s down there.
Fingers crossed no granite 🤣
So, are you doing a complete drill string in this diameter and, can you share why you are drilling a 3m hole 250m deep? Surely not to cut up into shorter lengths and sell off for underground tanks or the like🤔🤣
Hahaha. That’s gold. They’re for ventilation in underground mining. We’ve done a bunch at 1.8m with our current big rig…
But this size is next level. Custom machinery all round to handle the torque that will be generated at that diameter.
Mmmm... pink lemonade.
🤣💯
12:03 Slinky!
Yesss! Finally someone saw it.
That’s what I thought too 🤣
👊💯
Is that ISO 9001 certified?
We follow ISO guidelines & Australian standards, but don’t seek certification for in-house items like this.
Ground up the Pink panther. LOL.
I literally laughed out loud when I read the original comment 🤣🤣
@@halheavyduty For sure. Good stuff.
@@halheavyduty Great channel. Number 6 just started on a CNC.
👊
I had to go double check the hole size that the drill will be drilling. 3m diameter by 250mm deep ( 0:55 ). Is that actually a footing for something? At 250mm deep it's barely what I'd call a hole.
I checked the description and the description says 250m which IS a hole.
Great spot 🤣
totally screwed that up in the intro. Yep. 3m diameter… 250m deep.
Wild
@@halheavyduty What on Earth is a hole that big needed for? Next question is how is any drill rig going to power that thing into Queensland?
Mark from Melbourne Australia 🇦🇺
They’ve custom built a one of a kind rig for it. They’re using the tech to drill large ventilation holes for underground mining
Before you cut the thread you went back & forth (I think) 3 times, then started the thread. what is the reason for that?
I don't know whether you know of Curt ice at CEE, he does a lot of UA-cam (If this is new to you) look him up he does a lot of heavy work for the big equipment & he is in Oz.
Excellent question.
So on a the first of a new thread (or a new tool setup) I’ll add -1 of toolwear for the first pass…
Just to check visibly I haven’t accidentally stuffed up a number somewhere.
It was how I was taught, and it just made good sense. Once I know it’s all set up right, the 2nd one onwards I don’t do that.
Only on the first one. Just to check.
when you mention the expected torque for the drilling. How much do you expect it to be?
I’ll double check with the drill designer on Monday and post the exact number in the next video.
Great question.
