???? (1) 1/5 = 0.020 ?? :scratch: (2) Surely the formula only applies to a 60 deg screw thread ?? Dave BC |
| mklotz:
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. |

Yep, Elmer's engine number 11 http://www.john-tom.com/html/ElmersEngines.html 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.
