I just got a few new Lee molds with the alignment pins and I need to remove the sprue plate to polish everything up before using them for the first time. This has probably been brought up before but how do you remove the sprue plate screw and still have it work properly after putting it back together? I want to only do this once so I hope I get it polished well enough. Also, does anyone know if these new molds are made of a more durable aluminum than the old style?
