At large, whereabouts unknown.
I have a modified LBT mould that was converted from the LBT sprue plate design to an NEI style aluminum plate. I bought it cheap, and it's being a pain. The sprue plate galls in the pivot area, leaving scratches & gouges around the pivot bolt. A similar mould with a steel sprue plate doesn't have this issue by the way. I've cleaned it up once, & lapped both areas smooth again on my trusty chunk of 2/4 in. glass with 800 grit & light oil, lubed it with some left over Bull Plate and it immediately galled again as soon as it got hot. This time it won't go back together until I'm confident it will work. I briefly considered a lubricant like LBT mould lube, or a high temp antiseize, but I'd prefer a dry lube. My real concern is that I may need to have the plate anodized so that I have dissimilar contact surfaces. Since the mould has been modified for the big sprue plate I don't believe an LBT sprueplate is the answer. The meathead who modified it also milled the LBT venting from the top surface of the mould. Those of you familiar with LBT moulds know that the sprueplate & mould venting were developed to work together as a system. Any suggestions on how to proceed?
