Ouch! thats a bit spendy for a thread :)

Just found a Torch video and they have a similar head to my Tapmatic - theirs is Procunier but the action is the same it seems.

The only benefit they have is that its all pre-programmed canned cycle stuff. I don't have that luxury but at least it proves it can work.

I will have a look at the specs on the head for tap-travel below the stop point and see if i can come up with a method of programming :) From memory it was 5mm below the stop point to where the feed disengaged so for a 10mm deep thread you would stop feeding at 5mm, wait for the clutch to disengage then feed out.
