????

(1)  1/5 = 0.020 ??  :scratch:

(2)  Surely the formula only applies to a 60 deg screw thread ??

mklotz:
Whoops! (I've fixed it.)

Yes, it applies to a 60 deg thread. 

Russel:
Well, I didn't have anything to thread the test part into until today. I had to tap a hole 5-40 today on a project I'm working on and decided to try the test threads out. Very nice fit, I'm happy about that. When I cut the male threads on the test part I threaded the 5-40 die split screw until it just touched the other side of the split, then gave it an additional quarter turn. Looks like that turned out about right.

sbwhart:
Great job Russel and well shown :thumbup:

In your last post it looks like a part for a radial your making there  :worthless:
 
:D

Have fun

I took Bogs advice and started with I thought was the most difficult part to machine. 18 2-56 drilled and tapped holes done and only 6 left to go on this part. You can read more about it on HMEM.
