Twenty years ago I was working in a shop that manufactured deep water well column pipe, usually 8" diameter. I learned an incredible amount and just hated using thread wires on those pipes, especially ones that were 12" diameter with tapered thread (grease for the win)! Thank you Chris for taking the time to post such quality content!

I've watched this three times and learned something new each time. Thanks again!

I worked as a machinist for a while operating CNC milling and Manual lathe here in Indonesia. I can see your skill is on a different level. Love and enjoy your videos. You're living my dream job.

Great job Chris! At a high level, as always!

This is the type of work that separates the men from the boys and the reason why guys like Chris get paid the big bucks. This one was very enjoyable. Great job Chris.

Yeah my job I’ve been at for 7 months now was the first time I have used thread wires. They are such a pain in the butt to use sometimes. Watching how you set them in there and lines them up gives me a better idea how to use them. Good lookin part! I make different kind of spindles as well. Keep doin what you do!

Use little bit of a grease so the wires stick to the part.

Espectacular Cris 👍👍👍

you got that 3 wire technique down pat

Thank you for the video in general and the tip for getting thread wires in the right place particularly.

Nice work 👍

Chris what are the runouts on both bearing diameter after this turning operation, do you need to do grinding operation on bearing diameters after this, I am curious..

I worked on manuals for a long time,when I first saw and understood constant surface feed on a cnc I was rather envious.

Hi Chris, yet another interesting video of a component that most people will never see or know about but without which are modern world would grind to a halt. I am not a machinist just a carpenter trying to learn across other trades. I am curious as to the amount of material removed from the rough forging to the part as is at the end of this video. I assume that there would be calculations for such material wastage but don’t know how it is expressed. Mark from Melbourne Australia

your programming speed is amazing. i would be scared to death after hitting the start button.

That was pretty cool. Wonderful video work. Music was good.👍👍👍👍👍👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

Should only chuck on rough material with a four jaw chuck not a three jaw in order to not damage the scroll of the three jaw?? Beautiful work!!

That 4-jaw chuck is too big, and it won't close all the way, so that's why I'm using a smaller 3-jaw chuck. Never had a problem with it.

Difference between the two is that VNMG has no clearance. It's a neutral insert. VBMT is more suited for finishing.
