I have a Rigid Model WL 12000 12 inch lathe. I want to turn bowls and need a face plate. Rigid tells me they are no longer in production. There was a 4 inch faceplate (AC 8040)and a 6 inch one (AC8060). My spindle is 3/4 inch and I can't find a faceplate, or an adapter, to fit. Are there any old faceplates out there or a substitute?
