The molds that I use get alot of use and I'm here to tell you that they just don't stand up to much use at all, I do all the recommended fixes before i start to the Lees. I add a flat head screw to the side for something more solid for the screw plate cutter to pivot on, i change the pivot screw from alum. to stainless steel and add a ss set screw to retain that screw. Then i start on the inside, lap all the cavities, and Leement where required, as most lees are smaller then advertised, remove all the burrs, etc. After all that and you're up and running and something else breaks, usually the sprue plate handle, either the wood breaks or the metal spud. Then you pick up a Saeco and it's pure casting joy!!!!!
