Posted this on another thread but never got it solved?
"In regard to the Lee furnaces, I purchased one (a 110 V 20# bottom pour) from another shooter and it's served well though recently the pour-nipple has been freezing up (ie the alloy solidifying), this first occuring when melting a large volume of X-Ray shielding. It's an intermittant thing and, left to itself, it "melts" again and will again "pour" when triipped as it should. If in a hurry, a propane torch to the nipple facilitates the "recovery" but it is irritating. Any solutions? Other than patience?"
