I just noticed I have two loose tote studs on my Type 14 bodies..
I never really paid much attention to this but it was bought to my attention..
After checking the OD (outside Diameter) and PD (Pitch Diameter) I fine the newer type studs Stanley stated making around Type 10 (my guess) to be way undersize..
The old style studs had cut threads and a fatter diameter the newer style has rolled threads and an undersize diameter..
The threads are a #12 -20 that is not standard but what is called a Bastard in thhe trade.
To find the diammeter of a # thread you times the #x .013 and add+.060 a 0-80 thread had a .060 dia. and a # 10 has a .190 and a #12 = .216
The Type 14s have an over sized tapped hole and I made some custom studs so to be sure not the pulled the threads out of the body..
I cant fine a 12-20 die any place with out a custom order so I did some thinking and use my 1/4-20 adjustable Lil' Giant Greenfield Tap sets and crank them down to 12-20 rough and finish..
The rough cut is in the tail stock of the lathe loaded foward whic looks backwards and the finis I am holding in the Stock Handle..
If you have a very loose thread you can get an over sized stud of at the least find a Pre-Type 10 stud with cut threads not rolled..
