Lathe threading disengagement set-up

[Floradawg]

Hello gatz,
Very effective. Like Frank S. I like to thread away from the chuck and also have 1/2" & 3/4" Coventry die heads but I like your setup.
Question? The tube over the leadscrew is that an add on? I have some thoughts as to what for but would like to know.
Cheers.

Hi Mate! Haven't heard from you lately. Obviously neither have you heard from me. Nice to know you're still around.
