This Thread Even Fooled Hal (It's Deceiving!)

Today, Matt is programming and machining a dual start thread. These threads are very uncommon, but if you don't look out for them they'll drive you NUTS! 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.
