    bottom tubes crushed, how bad is bad?

    To repair or replace that is the question.
    Will it affect judging if bottom tubes have dings in them or should they be filled or replaced.
    What do you guys think? (can't believe I just said that)

    Why not just repair them?

      If you are going to restore a motorcycle you have to ask yourself this question. Did this motorcycle leave the factory with dents in the sliders?

        Chris, He is talking lower frame tubes, not sliders. But your point still applies!

          Replace the tubes. If you don't, and weld them up, it's not going to be - as chris said 'as it left the factory', and you will take a points hit on it in judging. That kind of repair can be seen by the judges.

            There is not a frame in the world that will be "as it left the factory" if it has been ridden at all.
            Pitting, Accidents or what ever all get fixed in one form or another so the question is fill or replace??
            Braze, weld, for bottom tubes and body filler or icing for pitting?
            Do judges pack magnets for brass or filler material inspection?
            Sorry guys just asking questions to learn. I have never had a bike judged and sticking my toe in the water to check the temp.

              My frame guy used a cutting wheel and cut a line up the center of the dent. Then another perpendicular cut on each end. Bent the metal out, reformed it, bent it back in and welded it. After dressing the welds down the former dents are no longer there. NOTE! You will have trouble doing this on most Knucklehead era frames as they are double tubed in this area and there is lots of brass between the two tubes. Ya can't weld where brass is present.
