Attachment 199346I've got a couple hundred jig-spinner-lure molds. Doits, Hilts, Herters, Cast Customs and custom
machined. Jig heads from 1/100th oz. to 8oz. The bigger the cavity the easier they pour. The key
is pure lead. The better molds like the Do its sell same mold with different pouring throats and
vents. The molds have color coded handles, the black is the hardest one to pour but leaves the
smallest "wound" at sprew break off point. The blue series for same jig is easier to pour but leaves
a bigger sprew. The 1/8th oz and under can be a pain if you don't have fairly pure lead. I never
smoke the molds or use release agents. If mold is properly preheated, lead is the proper temp
and fairly pure you will have no trouble, if you do it is a malfunction of one of these 3 things. Junk
lead can drive you crazy in the smaller molds.
