    Lumiweld. Tried them, failed. Tried again, failed worse*

    Some people say they've had success but they're obviously cleverer than me.

    You mean lumiweld, technoweld etc? Not actually welding as there is no penetration, it's a capillary action joint. You need the base metals fucking clean, wire brush and acetone are best. You then heat the joint and drag the filler rod along, finishing it off by running a stainless abrader rod through the molten pool to pull out any impurities. It's a black art but you can have some success with enough trial and error.

    See the guy in the picture? His name is Craig, I used to work with him at BOC's fabrication research centre.

    PS - what are you trying to join?

    I've had success with them. I'm way too cheap to buy Touratech tat so I made my own BMW rocker cover with oil filling hole using a BMW cover and a filler from a Honda stationary engine.

    Nothing, reshaping 2t feed from the crankcase. Not sure if this or milliput would be better.

    It's basically brazing, not welding.
