Response to Well.....I threaded the end of a piece of .390 dia O1 drill rod, a couple observations....

But I still think you should have single pointed it, just for the practice, of course happy.gif. Are you going to heat treat the O1, or just leave it as machined? And if so, what's your process? I have some O1 on hand I'm using for various parts, it machines pretty nicely. But I haven't tried hardening/heat treating any of it yet.

Re: split dies, sorry, no such luck. I have a Sears Craftsman tap and die set I bought about 30 years ago, I've only lost/broken a couple of taps over the years. Not the best, but it's done what I've needed it to do for a very long time, and it's standard and metric through 1/2"/12mm, so it covers a lot of ground. Later.
