Well Reed...My father used to make his own molds and get about 10-12 bowls out of a set of molds...then he finally had the set of molds made Frank bought...after his death in 92....I myself built many of these bowls...any bad bowls that came from the vender that needed mold trimming or bad color, or just anything wrong were sent back to the vender. My father made a jig to hold the bowl in a drill press so that the tool my father made drilled, tapped and cleaned the thread start all in one shot. Then flip the bowl onto another jig to drill the 3 leg holes, take a valve and screw it in, take 3 leg wires and squeeze them together to fit the holes. Done Im sure Frank has these jigs. As the orders went out they were heat stamped with the date and # of bowl. So I don't know what sanding, cutting, waxing, polishing and finishing needs to be done, unless he has a different vender injecting them for him and he his just dealing with the bad ones himself. I think it was AZViper that told me he had got a bad one.
