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.

I was suggesting all critical dimensions be around .020" over, OD and ID. Then heat treated (things move around at 900F for 2 hours) then final machined. But that could be a logistical nightmare. I have a machine shop and a furnace lab about 100 feet away from my desk, haha.
I would suggest going to one supplier to have them make the part. That way they own all operations and processes even if they sub out work they still have to deliver a per print part. Let me know if you want some help with drawings.
I suggested moore performance because they make input shafts for nitro drag cars. He must outsource his heat treating...
