    The broken casting

    Thanks AAMETALMASTER & Old Skool for the tip on 4043. I'm brand new to the forum. I sure do appreciate your feedback!

    Here's a picture of what I'm trying to repair. Unfortunately I do not have the missing section of the case/motor mount that cracked off. I planning to clean up the break with a large holesaw to give me a clean circular edge, then TIG weld in a new circular piece of aluminum billet (6061) that will match the radius. Any opinions?

    Repair cracked Sportster engine case?

    Does anyone have a filler rod suggestion for welding on a Sportster engine case? Would 4047 be the best material? Thanks, Terry
