    My poor man’s Speeditwin needs a new ear on the exhaust housing,
    or the other one cut off to match. The best I can do is alumi-braze
    one on, or “try” that is. I’ve only had about a 50% “happy” rating
    alumi-brazing any thing. Anyone do the same “ear” repair with
    alumi-braze, and if so, what were your results? Did you weld the ear
    on from the top side, or bottom side?
    I just happen to have a scrap of 1/4″ aluminum plate big enough.
    Guess if it don’t work out, it can be an “earless” Speeditwin!

    Ted Marston did all my heavy duty welding. He is a real artist in aluminum. I have a 50% success rate with brazing. I do go through a lot of stainless steel brushes. When the posts break out on the old drum muffler Speeditwins, it causes casting damage that is hard to repare.

    Buc, have you thought about taking it to a weld shop? My propeller fixing guy here in Michigan specializes in fixing skegs. Those guys with heliarc welders do some amazing stuff.

    This summer I broke down and took my Cadillac boat to a “professional” with 40 years experience welding
    to weld up some stress cracks in the hull. It leaked before I ever got it in the water, lol. I had it upside
    down and laying underneath, I could see daylight thru the welds. Not going back to that guy, lol.

    Nice job Tubs. Only thing I don’t like about using alumi-brazing rod is that you can
    only weld from one side of the piece.

    Tubs, I’ve done a couple of skegs using alumi-weld and my oxy-propane
    torch set up. Not sure if they’d hold up for every day use, but they
    survived the barrel test!
    The first time I tried putting one on, not thinking, I “vee’d” both sides of the
    metal, brazed up the first side, then of course, flipped it over
    to braze the other side,……. and then melted the first side, lol.
    Now I just make one deep Vee, and dress up the unwelded side with a little JB
    weld before painting.

    Tubs, I like your ingenious clamping method of holding the new skeg in place for welding!
