Jerry VanThreading tool needed for Waltham threads
I need to produce several, small, thumbscrews with a Waltham #1 thread, (.0598 X 110). Can anyone tell me how to produce this thread? I believe Elgin had a very similar size as well, (.0591 X 110). My lathe will only get as close as a 112 pitch. Please help.
