.......to make my OWN threaded cases for use in my Stoney Point guage??? I believe that it is a "special size and pitch." /ubbthreads/images/graemlins/blush.gif
Save yourself a hell of lot of aggravation and expense. Go buy the sinclair seating depth tool. www.sinclairintl.com costs under $30 and as accurate if not more so than the stoneypoint. I have two stoney points and tap and die for sale if anyone wants them.
From their FAQ:
<font color="blue"> </font> Q: What is the thread size for the OAL Gauge? I am an experienced machinist and would like to modify my own brass. Can you provide the proper drill bit and tap?
<font color="purple"> A: The thread size is 5/16" x 36. This is a special size drill and tap that we can provide to experienced machinists. Contact us for details </font>
I have a tap press I use to make my tools - I don't think you could make one without something like a tap press to get the correct alignment.
They only charge $6.50/case - so I think I'll just send them a bunch of cases. Only $4.75 total shipping.
