I have an original RCBS lube-a-matic. There is a screw at the bottom that has a 1/4" hole thru it (part #18 on the diagram). Mine has broken off right at the flanged part on the bottom and I cannot screw it in far enough now. RCBS no longer makes this part, but it is about 1.5 inches long, has a 1/4" hole all the way thru it and has 7/16x14 threads. It would be simple enough if I had a lathe, just take a 7/16" x 14 tpi bolt and drill a 1/4" hole all the way thru it......but, I don't have a lathe. Does anyone have this part that they would sell? RCBS sent me one for the RCBS II lubricator, but it is 3/8" x 24 tpi, so it will not screw in.
on the parts diagram, it is part #18.
