hi every one' just sort off fishing for ideas im building a hybrid 16v mini and have to weld two different drive shafts from different cars together have looked into this abit and some of the main probs are twisting and snaping.they way other people seem to do them is machine sort of a step out shaft then weld then sleve then weld.will prob end up doing it like this but just wondered if any body on here knew of a better way
