My next project for machining class is to make a thread protector for my P226. I will likely make it out of stainless 303 or 304 since there is an abundance of suitable scrap pieces laying around.
So, I post here asking for tips and hints at how to do it. I talked to my instructor and he's game, so I have his expertise on tap, but I come to ya'll who have experience making them for the low down.
As I think about it, I come to two issues. Since it's going to be knurled, I figure I will need to run the bar stock with the knurling tool first due to the pressure applied. Then i figure I'll drill the inside diameter and ream to within min./max thread diameter, then thread with a boring tool. I figure if I want it, say .625" long, I need to drill and ream or bore to around 1" to give enough clearance for the boring tool.
Alternatively, I could do the above, and then just run a tap in to thread it. We don't have a 13.5mmx1 tap at school, so I can look for one.
How do you guys do it? Am I way off?
I haven't done any internal threading other than with a tap in the tail stock.
If it's simple enough, I'll do it tomorrow, otherwise the quarter is over until end of the month.
