HAL Heavy Duty Machining Australia

About

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 once a fortnight (or weekly if possible...) and really appreciate all the comments from around the world. You guys are awesome. Thank you.

Video Description

In today's video we are facing a large approximately 2 ton agitator that's almost completely covered in hard face, making it EXTREMELY difficult to grab in the Megabore Lathe. With some creative work-holding we manage to get it into "The Hulk"... and then the fun begins. Enjoy! ABOUT HAL HEAVY DUTY We're a real life Aussie machine shop that specialises in the drilling industry. 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 pair of 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 2.7m (9 foot!) drill bit that'll weigh upward of 20 tonnes and we're getting ready to send it 250m (800+ feet) deep with a custom 100t big rig. 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!
