I've got a busted (H-D motorcycle) transmission case , cast aluminum . It's busted too bad to repair and use , but will be a good practice piece for me to learn on . I recall dad telling me that special goggles are needed , to see the al as it reaches the proper temp without melting the whole thing . What kind of lenses do I need ? I also need a recommendation on filler rod , and anything else y'all can think of that I need to know . One thing I have learned here is that oxidation is a major problem with al , and cleanliness (oils, etc) is extremely important . Not likely I will do this very much , but it would be a valuable addition to my skills . Might even get good enough to weld up and retap that stripped spark plug hole in my rear head . Inserts are a pain ...
