I’m selling my Chefware kits sphere jig, got a different one and liking that one more. I’ve used this jig for maybe a dozen spheres or so, it does work but to much fiddling to get good results. When i bought it, it was on my 1221 lathe(12” swing). Then i upgraded to a jet 1840 so bought the 18” riser bar but didn’t realize they sent the 16” by mistake. So i made my own. So all three riser bars are included. Other size bars are available from there web site. It also includes the carbide cutter, and instructions. jig can also be used with there thread cutting jig(not included) $175 plus shipping inside the USA.
