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 !!

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.

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.

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.

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 👊

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 )

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.

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.

Dude that’s awesome. The LHC is one of the biggest man made structures there is. Very cool.

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.

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 🤣

Hey mate, great question. At this stage I can’t share any specifics as it’s a custom thread under development but might be able to in future videos. Thanks for understanding. Judging by the quality of the question you clearly know your stuff.

How do you know what size the pitch diameter is? Do you just cut the male thread to fit? I thought I heard you say 30 pcs? Are they interchangeable?

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 have a bunch of checks along the way. As it’s a prototype, the most important thing is to check its machined to exact size & thread depth. It then becomes the tester for the pin (male).

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?

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.

What was that he was talking about the nose radius of the finishing cut? Junior machinist here.

@halheavyduty

24 күн бұрын

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.

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.

4:07 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.
