Well, I can't argue with that, John :bow:. I'm happy to be proved wrong, but sorry if you've had to waste any steel in doing so. It certainly simplifies the design.

Andy,
No problem and nothing wasted as I wanted to do this to use and not just as an exercise.
When threading I always leave the half nuts in and reverse the machine I find this far faster than waiting for the dial and making mistakes.

The fact you can put the next cut on whilst it's going back also saves time and because the infeed is always in the same direction you don't have to worry about backlash. For me it's a plus so any trials are just that.

I could see it being a problem for many who have machines that can't reverse easily and the screwed chuck problem is bound to raise it's head but I reckon that is overrated.

Considering how simple these have been demonstrated to be, I'm surprised I've not seen them available commercially.
Darren:
It just needs someone to come up with an idea .... I'm amazed this didn't happen 100yrs ago  :dremel:
Bernd:
Well, my fear of to much backlash has been cured with that vid.

Thanks John.
