Welcome to our heavy duty machine shop. We specialise in the drilling industry and are located in Central Qld, Australia.
My name is Matt, and in a nutshell we make super heavy duty gear that drillers typically love breaking.
Hydraulic cylinders, drilling crossover subs, drill bits, recovery gear... the list goes on. If it's drilling related, we do it.
WHY HAL? We chose to name the channel after my late grandad Hal.
After working on a drill rig since the age of 14, Grandad then "retired" from drilling at age 60 to "the machine shop" ... and then proceeded to work until his 87th birthday.
THE CHANNEL This little channel is just about sharing some of the weird and wonderful gear we get to make in the machine shop... and how drillers manage to break it.
I upload one video a week and really appreciate all the comments from around the world. You guys are awesome. Thank you.
Always love CNC machines cutting threads. A great demonstration of how they pick up a point on two different encoders { or 3 in this case) in real time and feed appropriately.
Well done this was a quite good quality video and pleasant to watch you are getting there mate. I’m working on something to make it even better for you to take videos. Be in touch soon. Cheers.
do you have plans to roll thread root of box connection? --when Hughes tool produced pipe joints for Glomar Explorer russian sub lift they rolled thread roots of pin and box--increased joint capacity to 22 million lbs--very secretive however with no images or video footage ever made public
Not at this stage. I’m pretty sure they’ll hold up to the task. If they don’t, I’ll definitely investigate more. Thanks for the comment. Very insightful. Man I would have loved to see how the Russian sub lift was done.
I try 🤣 Man it’s hard though. That’s a bloody good analogy (cloverfield)… at least I’m not the Blair witch. When the channel gets a little bigger (and I’m not flat out in the shop) I’ll rig up a more stable setup.
Play with feeds and speeds. I have found a little slower on the speed or a bit more pressure on the feed will remove that vibration. Small adjustments please, speaking from 34 years in front of machines.
Thank you very much mate. Definitely going to play around with it next batch. Really appreciate the suggestion. I personally think you’re bang on the money.
Another great educational video!!! With the CNC program, is the cutter lead in angle parallel to the thread form. Say 30 degrees for a metric thread or would you set for just under 30. Cheers
Nice job with a good finish on the flanks of the thread. Old machinists of the like working in the very machine shops around the steam era would be blown away with what we do today. Certainly some major steps forward in metal removal rates with carbides over the old carbon and HSS. Well done. Cheers Ian
Thanks Ian! Yeah, I agree. My grandfather Hal would have loved to see it all. He must have cut 1000 crossover subs by hand in his time. To see something like that big sub would have probably brought a tear. To people who understand machining, it’s truly phenomenal how far we have come in just 20 or so years.
I worked for a geologist many years ago, providing support to two drilling rigs doing investigation work. I have a vague memory that all the core barrels, flights and the bits had tapered NPT threads, do these big units have similar threads?
I subscribe just wish your content was more longer and explain more about the process the tooling etc more like CCE but I’m definitely a fan love the work
Thanks mate. Yeah, with most of the videos I try to give more explanation. This was just a moment I caught yesterday and thought it was so enjoyable I just had to share it. Appreciate the feedback!
It’s 4140 steel. In this case, due to the size, we won’t be nitriding it. The drive sub at the top of the rig will be done however - just to harden the outer 0.3mm and increase wear protection.
Are those tapper threads if yes what are they used for I’ve been wondering myself for about a year now also I’ve tried the WMNG inserts out they cut amazing the material I had problems with because it was a interrupted cut was no problem anymore and the surface finish at higher feed rates is also better then the dcmt inserts the chips also don’t fly high in the air they fly down nicely
They sure are. Being used as tool joint threads for our upcoming mega drill project. Used to handle the torque of a 3m diameter drill bit. Honestly I’m a massive fan of the WNMG. It’s our most used carbide by far. Good for roughing, and the finish is more than sufficient for the kind of work we do.
@@halheavyduty the finish I’ve been getting in a steel that usually gives bad finishes is really good for my roughing feed I call it roughing but it’s only 0.15 mm per rev but our machines aren’t as sturdy as yours
Well-behaved long coils are so satisfying. Steady and tailstock seems a bit like belt and braces for that length of part, but the result speaks for itself. Very nice!
I was watching and thinking you were super fast and smooth, LOL, cnc to the rescue ;) Always watch Keith Fenner, TurnWright machine works. I work similar for tinkering, DRO means the numbers on the micrometer or calipers! I enjoy cutting threads but too chicken to cut towards the chuck so my first mockup pass ends up being a left handed thread!
Hahahaha. Smooth AF We will have to cut the drive sub itself manually… so that should be fun! I actually find manual thread cutting really relaxing. You just get in the zone with it.
Very mesmerising 🤓 I think that is fair to say that the four best RU-vid engineering/machining channels are all from Australia! (Kurtis, Matt, Matty and Max) 👍👍👍👍 Thanks for the vid. All the best, Paul
looked and sounded just like it should as we alway say with drilling and big thread cutting " it has to sound like bacon sizzeling in a pan" if it does that then its running just the way it should something i learned from a old machinest and never had a problem when it sounded like that
The pipe is 16mm thick, 1 tonne, 9m high pressure steel. The drill rods will drive the “mega drill” … the beast drill under construction. It’ll be the largest and most powerful rig we have ever had in the fleet in 60 years. Can’t wait to film it drilling 👊
Nice depth of cut brother. I also like how it ain't breaking chips and ruining the finish. Taper threads turn me on, get it? :P I may suggest that you may be a cunt hair over centre height judging by the sound.
@@user-sp4gy7ko5l Looks like you two are specialized in API threads. Just for curiosity do you mind me asking what is the smallest API internal thread 5 TPI you might have machined. I couldn't find any tooling supplier that has a suitable tool.
@@mehmettemel8725 Sir to be honest i am a manual machinist and have never turned a tapered thread in my life. I also do not use CNC machines. Sine bars can get rooted as far as i am concerned. My experience come from my own two hands, vibrations and sound signatures. I can tell if the coolant is too hot just by the look of it (by the way all the coolant sucks these days). You did not specify your internal diameter please clarify that and i will do my best to help. If there is a tool maker that makes the tool you are after i will find it as a tooling supplier. 5 TPI seems rather large, we should have no problem sorting you out. What material are you turning?
It should. I’m a little limited by z axis grunt. Will be doing another batch of them soon. Will be good to put all the suggestions to trial! Thanks for commenting mate.
I worked at an engineering company maching a lot of 316 stainless. The guy running one of the large swift manual lathes needed to put a large hole in a part, so he borrowed a 90mm u drill from the cnc lathe operator. He was told that if he wrecked it that it would be on him! I saw the result of incorrect running of the u drill which now had a 90 degree bend in it! The cnc guy said he needed to tell the workshop manager what he had done as it was the only 90mm drill and the cnc guy needed it for a particular part!
Man... I'll tell ya, he's not wrong. I _did_ need to see this. Makes me feel like a catastrophic failure of the machine would be breathtaking although probably it would just be a single loud snap. Very cool, fascinating to watch. Thank you. 🙂
@@halheavyduty Loved it, and your work is beautiful. I should have gone into machining as a career path because I really do find it fascinating and the ability to create omg... I'm very active in plastics 3d printing but I long for the ability to work in metal. Have you had something like this break on you? Is it spectacular or does it just kind of pop and stop?
Greetings from Ireland Matt. I served my apprenticeship training to be a tool maker in the early 80's but when I qualified we were deep in a recession so I went into the next thing I knew best, trucking. 40 years later and I still love engineering and I'm enjoying your channel. Best wishes from the outer edge of Europe and keep the videos coming. 🇦🇺 🇮🇪
Hey there mate! Thanks for the great comment all the way from halfway across the globe! My wife and I have Irish friends camping on our property at the moment… and man… I can listen to your accent 8 days a week. Truck on my friend!
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.
It’s possible I think, although this type of Udrill isn’t designed for it (to my knowledge). There are other types that you can use as a boring bar. Maybe this one will too. We just use it for drilling though. Make a hole big enough for Kong the boring bar to get in and take out heavy cuts 🦍 Where are you located mate?
