Machining 0-Ring Grooves (To Fix a GIGANTIC Leaking Water Swivel)

In today's video we're making some alterations to a gigantic water swivel that's been leaking on the big rig. We need to put two O-ring grooves into it. I'll be covering how we calculate O-ring groove width & depth, as well as how we machine them in a part that's a bit odd to grab. We'll be using 'The Hulk' - our 11 ton Spanish Megabore lathe to get the job done. 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're a little shop that takes on big projects, and the latest is our MEGADRILL project where we're manufacturing a 3.0m (10 foot!) drill bit that'll weigh upward of 20 tonnes and we're getting ready to send it 250m (800+ feet) deep. If you want to catch up on the progress... here's the latest on the project! https://youtu.be/OKPr15PucGQ?si=dTVN39xDaAYi3Je9 https://youtu.be/mK3slsayuZM?si=kB4koTj7MrkngnlJ https://youtu.be/qtsz7cLtDY8?si=LL-ip0p-M-FVsoTs https://youtu.be/j_g8wMRu7wc?si=_PO-F-opHgggzjU1 https://youtu.be/r796Mw4j1gM?si=_9yPWEgUw4b10d5e 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!
