I am in the process of another jig for the G0766. I am making a threading jig for urns and screw on lidded boxes. I am starting with 3/4-10 UNC x 12" lg all thread rod as the lead screw. I will need an adapter to fit the chucks that have 1-1/4"-8 threads (female). So I need an adapter that is 3/4"-10 unc (female) x 1-1/4-8 (male). I have gone through a few searches on Google, and have gone to local Woodcraft store and no luck yet. Anyone have a source?
