I have a couple of Lyman molds that will not adjust for tighter spru plate fit. With the set screw loose, and the screw that holds the spru plate on all the way tight, I still have a floppy spru plate. Seems the screw is too long or the hole it goes in not deep enough. Anyone with experiance with this? I'm not used to casting with the plate flopping around on it's own.
