Скачать или смотреть The LARGEST Drive Sub I've Ever Machined!

Today, Matt is ripping out a full arsenal of tools to aggressively remove over 350kg (850+ lbs) of metal to machine up the LARGEST casing drive sub he's ever made.

Starting out as a solid billet of 4140 steel... the finished product is almost a piece of art.

Enjoy!

ABOUT HAL HEAVY DUTY

We're a real life machine shop for a 60 year old drilling company located in Central Queensland, Australia. Our job is to keep rigs running in the field - fixing all the stuff drillers break and creating all the custom gear they need to get the job done.

We run two CNC's, manual repair lathes, a few mills and a big green Megabore Lathe we call "THE HULK"... and are constantly having to make weird and wonderful tools for odd (usually oversize) jobs.

We release our weekly video at 1pm Friday (AEST), so be sure to subscribe if you want to see stuff you really won't find anywhere else.
