    How do you remove a crank when the threads are stripped and a crank puller tool can't be
    screwed into it?

    Cut old inner tubes and use them as liner underneath handlebar tape.

    Probably extra handlebar tape will be necessary, to accommodate the extra diameter.

    1) cut oversize threads, use oversize puller
    2) use a two or three armed bearing puller (try a garage)

    Force a wedge in between the crank and the bottom bracket, and hammer.

  5. If you remove the crank from the other side and then remove the bottom bracket, assuming you have
    a one piece bottom bracket, this will take it off. You can also try violence, a touch of the
    "shock and awe", or it is said , it you cycle on it for a while with the nut off, that it will
    work its way off.

    Try no 1. I've done it.

    I made a plate to go behind the crank and use a harmonic balancer puller to remove the crank. Well,
    that's not quite true, my teenage son used thing when it was time to remove the damaged crank from
    his bike. The plate (of course) had holes drilled in it for the bolts from the puller along with a
    slot to fit over the axle. .

    There's the Var #932 which clips on the arm and pushes against the spindle. Consult your LBS. The
    job only takes a moment with the right tool so it can't cost much.

    If you needn't reuse the crank, a small propane torch will expand the aluminum crank much
    faster than the steel spindle. Warm it and tap on the inside of the arm to let it fall into a
    bucket of water.

    This won't work well if you have smaller hands.

    People used to do this (maybe 20 or 30 years ago). Back then the standard handlebar tape was thin
    cloth or plastic. Today, padded handlebar tapes are widely available and have the same effect.

    I saw an old video of the 7-11 team putting a longitudinal layer of bar tape under the wrapped tape
    for Paris Roubaix. This would probably work better than an inner tube: more cushioning.

    It increases the diameter of the gripping surface, but if it helps, go for
    it.

    There used to be a rubber handlebar tape sold by Scott. I used it once on one of those AT-2 MTB bars
    and liked it a lot -- two layers under the regular grip area felt like a normal MTB grip. I haven't
    seen the stuff for a long time though.

    I like this idea for a paticular reason. I do ultra-marathon events and a great deal of my rides are
    for many hours. Over the course of a year the sweat from my hands that soaks into the tape results
    in that white aluminum corrosion on the surface of the handlebars. Perhaps if I properly wrap the
    inner tube around the bars I can make it somewhat water tight. OTOH, any moisture that does get in
    there may stay for a lot longer.

    The tube is not really doesn't give much cushioning even if you use it like tape and wrap it. Dense
    foam where you need it and not the pipe insulation stuff works better.

    Some one was actually selling foam handlebar wraps back in the 1980s. You needed really big hands to
    be comfortable with that stuff. The padded handlebar tapes that have been around for the last 10
    years (either synthetic or cork) are much more versitile and also much easier to install.

    It's still sold, and some of us do have big hands. I tried the foam, but didn't like it. However, I
    cut strips of it and put it under handlbar tape, and it does add some cushioning to the bars. For
    me, just tape on the bars leaves them too thin for my comfort.
