Well 9 months ago I couldn't even spell lathe. So I ordered one from Grizzly (a 0709G) and with the help of you guys, I'm on my second rebarrel project. This one is a test of everything I thought I knew. I'm rebarreling a Howa 1500. All metric threads. Not a problem with the help of you guys and a lathe capable of metric threading. I built a Truing fixture to mount the action in and made bushings to fit the bolt raceway to hold a piece of 1/2" drill rod to get it dialed in with. Got all this mounted and checked the trueness of the action. The action face was off about.002 and the barrel tenon threads were out of round and angled. So with my vast amount of machining knowledge, I proceeded to retread and square up the action face. I'm glad to say it turned out perfect. Used a boring bar to do the internal threads. Made a stub out of a piece of 416 stainless to be able to match the dimensions of the new internal threads. I cut these threads with the boring bar also. Used the same bit for both. I cut all these threads on the back side of the lathe with it in reverse.
