Last week the Lyman 20 began freezing at the spout. I initially thought of zinc contamination as I was using alloy from a friend's accumulation. I drained it and cleaned the pot bottom. Today I intended to warm it and possibly cast a bit.
After having it on for several minutes it had failed to feel warm. This one is at least 30 years old but of course it doesnt get used every day. And the question is----How many have had the electric furnace fail ? Did the element go open or was the demise from another cause ? Do you know if Lyman has replacement parts ?
It seems exploratory surgery is in order.
Thank you. Richard
