????

(1)  1/5 = 0.020 ?? 

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

Whoops! (I've fixed it.)

Yes, it applies to a 60 deg thread.

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.

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.

Nice result Russel

If you can thread silversteel/drillrod you can thread anything.
