Hi guys, i finally took apart the cross feed on my 16" and discovered what some Lug Nut did to it probably 20 years ago. He made a cross feed nut and machined out the bottom side of the casting to mount it. Does any body know how interchangable these are ? Mine is a single tumbler, will the casting from a double tumbler work as well. As now i am on a search for a new casting. Thanx Barry
