I have a Lyman 4 cav 44cal swc 240 that has a sprue plate with an issue.
I was casting the other day and the plate began to stop its return swing
from cutting. \
By this, I mean the plate seems to catch on the edge of the mold and stop,
almost like it warped.
Was it heat expansion of the plate causing it to swell or a lack of lube under
the plate?
Is it fixable or did I screw up too much?
Thanks in advance for your help!
Jeff
