Cleaning up some Lee Molds that's been setting in my shop for several years. I didnt clean them up like I should have last time using them or while using. Wont happen again. But I found a small amount of lead and small fragments had stuck to the sprue plate and scoured the tops of the mold while in use, luckily not over the cavities. But the worse part is scoured is toward the end and its from the sprue plate shape and the way its rubbing against the mold when closing. It has a bow or arch to it. When closed I can hold it up and see light under the center portion between the mold and the plate slightly. When closing it closes easy until the end part of the plate is covering the mold, where the scour marks are.
Is this normal?
Also found one of the locating pins on the 2 cav pushed back into the mold a bit. I set it flush on a vice and tapped the pin back to where it should be with a punch when mold was hot. But I'll mostly be using the 6 cav anyway but trying to save the mold if I can.
I have a newer (not used as much) Lee 6 cav mold and it has a slight bow as well.
I heated them up with the pot last night and tried to wipe off any lead fragments I seen. Removed the plate from the 2 cavity and will clean them up with brake cleaner and a virgin rag, Reapply anti seize to the appropriate locations hope for the best.
