I built and use a slow-rotation epoxy curing machine, for applying and curing epoxy coatings onto woodturnings. The motor is basically a rotisserie motor (2-3 rpm), and the spindle (self-built) is PVC pipe, 1 1/4" ID.
Mostly I use faceplates that I built myself, using PVC fittings attached to wood or HDPE plastic. These hold a woodturned item in place, using either hot-melt glue (if lightweight enough), or screws that penetrate into the item's tenon or base.
I would like to be able to sometimes use the same faceplates that I also use on the lathe; that is, heavy metal faceplates that present a 1 1/4" 8 tpi female threaded connection (normally, for the lathe spindle to penetrate). That would be handy for heavier turned items being epoxy-coated.
So, what I need is an adapter, that would be:
- male 8 tpi, 1 1/4" diameter (to screw into the faceplate), on the faceplate side, and
- female 1 1/4" ID, threaded to mate with PVC-threaded male, on the spindle side.
I don't know that such a thing exists (who but I would need it?), but if you do and know of a source, I would love to have that information.
