  1. After a prang a couple of moths ago that resulted
    in a bent dérailleur hanger I decided to make a tool
    to fix it, following the design of (for example)
    the Park tool
    http://www.parktool.com/products/detail.asp?cat=48&item=DAG%2D1
    I could have bought one but they're expensive
    and hard to get hold off.

    Anyway, I finally got it finished and took
    delivery last night. There are some pictures
    at
    http://wwwstaff.murdoch.edu.au/~dfarrow/
    and click on "cycling" in the second paragraph.

    In the end, I didn't do that much myself. I don't
    have much metal work stuff in my workshop. I got
    my Dad to turn up the head piece (he has a metal
    lathe) and a mate of a mate to do the welding.

    Pretty time consuming in the end. Had to go on
    a treasure hunt to find a bolt in Perth with the
    right thread. Had to wait for Aussie post for the
    head piece from Adelaide and then it disappeared
    while it was getting welded together. I did hacksaw
    the handle though and insert white plug in exposed
    end.

    That's really gorgeous! It's sure to last a lifetime. Might be a good idea to paint it or get it powder-coated tho...

    I've been meaning to braze up a decent wheel-truing stand for years.

    I have thought about painting it and have the means to do
    it but I was too keen to put it into action!

    It should last several lifetimes I think. One problem
    with it is that there is a bit of lateral movement at
    the head piece. The hole for the bolt is not quite snug
    enough. It just takes a bit of care when using it.

    Indeed, and that is what I used initially and several
    times in the past. However, I had trouble getting it
    accurate enough to stop making running noise. Maybe
    these new-fangled 9sp systems are a bit more sensitive
    than my old 6 and 7 speed bikes.

    Have you considered welding on (or otherwise attaching) an adjustable
    square, so you aren't relying on holding the ruler manually?

    Yes I have. In fact, that is what the Park version of the
    tool has. Couple of problems. First, the square has to
    slide along the arm for different size wheels and because the
    hanger axis is not the same as the axle's. Second, I couldn't
    think of a simple way to do it. This is not a tool I hope to
    need to use all that often! Holding onto the ruler is actually
    not much effort and you have to put it down to bend the hanger
    anyway. If it were attached to the arm I think it would get
    in the way. Version 1.0 seems to be working OK, version 1.1
    will be the same but painted. Version 2.0 will have a longer
    head piece so there's not as much lateral movement.

    movement at the head piece. The hole for the
    bolt is not quite snug enough. It just takes a bit
    of care when using it.

    You could fix that by brazing a sleeve over your M10x1 bolt, then chucking the bolt in a lathe and turning the sleeve so it's nice and round, and more importantly has a nicely defined shoulder. Then open the hole up so that it's a nice fit on the sleeve.

    You might need to put a circlip groove in there somewhere to keep the handle piece from sliding up and down the sleeve.

    When you use it, just screw the bolt into the hanger so that the shoulder on the sleeve sits nicely on the side of the hanger, and Bob's your uncle...

    Of course, all that is predicated on easy access to a lathe.

    Cheers,

    Suzy (who doesn't have her own lathe, but knows what sort of beer her friends with lathes like)

    I don't have my own lathe either. I live in Perth so I sent
    the specs to Pater (in Adelaide) and he mailed the head piece
    back. One doesn't like to comment on any perceived differences
    between how he and I may have done things.....

    It's nice lathe to - an old Hercules Model C with a collection
    of thread cutting gears. Picked the lot up for $100 about
    25 years ago. Unbelievable. He spent more than that getting
    a new tool stock shortly after.

    In fact, it's one of those pieces of equipment that has lots of
    stories associated with it. In my youth, I made a couple of
    stub axles on it that are still kicking around somewhere. The
    dog used to sleep on the pile of metal cuttings. She was forever
    causing havoc by bringing them inside as they stuck to her fur.

    Other things: I obviated the need for a circlip by leaving room
    for two nuts that lock against each other.
