I'm trying to cut a thread with my Harrison 140. I seem to have set the pitch correctly but I can not get subsequent cuts to line up with the first cut. I did have a problem with the leadscrew clutch slipping but I have fixed this issue.
I do not disengage the leadscrew between cuts so am confused as to why I'm getting a multi start thread.
Also my thread cutting indicator does not work when I'm using the leadscrew but does when the feedshaft is engaged.
Any help gratefully received.
