Hi
Lads
I have been having problems with a 8 tpi lead screw for my mill
Yesterday a friend gave me a 8 tpi "form tool" tip
This fitted my screwcutting tool holder
The pictures show the results on a bit of 3/4 stainless
The tool was wound square in to the work (not at 14 deg)
Now all i need is a bit 1 inch diamiter 24 inches long threading
