    Problem: back of bike, where the rear wheel slides in, is too narrow for the axle.

    Solution?: spread the rear forks/whatever and weld in a bar to bridge the gap you create.

    Anybody else had to do this? Suggestions?

    I saw a topic about it awhile ago.

    Search around. Maybe someone here has the link.

    Basically, take a 2x4 and find a way to leverage it on the rear stays and the upper tube of the frame, then do it again to the other side, about the same distance

    Use a wind up car jack, skwish it beween th chain stays with some pieces of wood to protect the paint, and wind out the jack.

    yep many ways work

    a long threaded all thread bolt
    nuts with washers inside
    start turning the nuts out -- pushes frame out pretty easy

    if troubles -- tie bolt to frame area -- so as not to let it slip out

    A pressure treated 4 x 4 and a ratchet strap.

    Muscle power, lots of sweat and a heck of a lot of cussing. Make sure your kids aren't around. :grin5:

    actually a very easy job to do

    actually a very easy job to do
    in the bike shop days
    it never took more than a minute or two
    but I will admit if doing this to my own bike today
    I may take up to five minutes

    ((not wanting to bend only one side of frame)) -- (((((that's not good)))))

    just ((a little bend)) ((on both sides))

    Only warning; make sure you're dealing with a steel frame. Aluminum does not like to be bent.
    I tweaked an old roadster for a wider contemporary hub with the car-jack method; worked fine.

    Use a sissor attachment with a body repair kit.

    Once I hit my late 30s, my frame spread on its own...wait, are we talking about bikes?
