this is what i would have for sure if i ever went into the resto business..just running parts for friends would go along way to paying for it..if ya market it a little..but now what youd do..just what id do..blocks fit easy..
here is what my buddy has(not his)..2 pieces, not 3 he has an oven and a blaster..but it might be good to look into the tumbler too..i dont know what that is....you see the wheels etc..theres hardware that bolts the pieces to the wheel..or you wire it..its gas and 115 volt stuff..so no 3 phase needed..
