The 15-5 H-900 is not much fun to machine but can been done. Thats why I suggest doing most of the machining in the annealed condition.

I cannot get his info at work. But google moore performance in san diego. I think this is his phone number (619) 296-9180.
When you say to machine it within .020" first, then heat treat, are you suggesting to cut it over or under the 24" length I need. The only other machining then is drilling and tapping. The diameter of the drilled hole is not as important as making sure the threads are dead on. So, cut to length (over by .020"?), heat treat to H-900, throw it on a lathe and turn it to 24", then have the hole drilled and tapped? Thanks Bryce.
