Did some casting today with a pair of older LYMAN 4cav molds. For some reason the stop plate screw on both molds loosened up. I tried to tighten them down, but they continued down into the bolt block. The threaded part is smaller then the unthreaded upper shaft. When you tighten it down it just goes down into the block, too deep to allow the sprue plate to "latch" under the screw head. Never had one loosen like this before.
I bought both these molds used, quite a while ago. One is a #454190, they are so old that the sprue plate pivot screws are slotted. But I think it's time to change over to Allen head.
Could I clean these screw holes & screw of any possible oil or Lube and use Blue thread locker to tighen these stop screws ?.
