I'll bet I have looked at this thread twenty times today and every time I thought...."those Do-It molds sure make it easy to make professional looking jigs".
I've used Do_it lead molds exclusively for over forty years. Others make molds, but Do-It products simply make things easy for even the novice. The mold halves seperate nicely after the casting is poured. They make a clean casting. Now factor in the full service type of company we have to deal with and its just one great big plus.
