I'm building a rotary adapter for a vacuum chuck and need to know the thread size of the outboard spindle. It looks like 14mm X 1.75 but would like to know before I buy supplies. Thanks.

Dan wouldn't it be easier to make one that fits inside the outboard end of the spindle or hand wheel with O rings like Craft Supplies sells (someday as they keep pushing them out, now says April). I'm tired of waiting so just got my bearings and am making the bo
I also made a homemade version of the EZ vac. When I got my "new" (1996) lathe and the spindle was longer than my old lathe I just cut the lamp rod to about 3" from the bearing unit, pushed a piece of braided hose over the lamp rod and just slid it into the spindle. It was a perfect fit on my General 260. This fit can probably be adjusted for other lathes by adding vinyl tape to the hose as necessary. Only takes about a second to slide it in or out.I made.a.home version of the Ez adaptor that uses lamp.rod and connects through the spindle without any fancy gadgetry. If you want a copy of the drawing email.me.
