270669 Erik Levin 2020‑04‑29 Threading die for 0.108-50
A truly odd size that some may recognize, it is a Brown and Sharpe size from
early 1900's. I need to replace several adjusting and lock screws that have this
thread. I have several screw in hand, and they measure 0.106 to 0.108" OD, so
the nominal may be 0.110-50.


What I do not have is a die. If I needed to make one, I would single point it on
the lathe. I need enough of them that a die is preferable if I can find one. I
have 3/32-50. 0.120-50. 0.066-50. 0.250-50. but nothing that quite makes it
here.


If I must, I can make the die or single point the threads, but I figured I'd
take a shot here to see if anyone has such.
