  1. I went to replace a rim today, and when I moved the spokes several of
    the spoke-head washers actually broke in two. Others are obviously
    split. In case you don't know what they are, they are tiny brass
    washers (made by DT) that go between the head of the spoke and the hub,
    supposedly for the purpose of improving the fit. I'm using 1.8mm spokes
    in a hub with large holes, so I thought it was a good idea.

    Is this normal? I'm a little bit bummed because I don't have any extra
    wheels, nor little washers to replace the broken ones. The spokes are
    formed with the washers in place and the fit is not so good if I don't
    use them. So I either wait until I can get new ones, or go with out...

    Any thoughts, ideas, suggestions? Thanks...

  2. A shop ought to be able to order them for you...

    If you have a radio control model airplane/car/boat hobby shop (even a model
    trains hobby shop) nearby, you can get some small washers from them no
    problem.

    Dear Ron,

    Be sure to stress-relieve the new washers. 🙂

    Maybe part of the same environment that destroys barend shifters in
    short time. I'm in dry NM now... thankfully. There doesn't seem to be
    corrosion though, on the washers or hub. I'm guessing that the size
    mismatch is so large that they bent too far into a cone shape. 2.6mm
    hole with a 1.8mm spoke...

    In what situations do you like to use them, Peter? Would it be a bad
    idea to go without washers at this point?

    Good idea... but the nearest one is 85 miles away. I guess a hardware
    store wouldn't carry anything similar? I basically don't want to wait...

    actually, that's right!

    cold worked brass is well known for stress corrosion cracks - and that's
    the kind of washer you have here. what are you using for cleaning?

    Uh... cleaning...? Hmmm... I guess Dawn and water, back when I used to
    ride in the rain a lot... in Hawaii.

    BTW, the spokes on either side of the flange were easy to identify by
    the elbow bends. I went ahead and rebuilt them without the washers...
    now I'll see how well the spokes like being bent to a new
    configuration. They went for ~10k miles with no breaks and no truing on
    the old build (WS AE15s).

    I increased the tension a little... ~115kg +- 20kg. The variation
    seemed necessary to get rid of the distortion at the joint and make it
    true. Hopefully the tension is not too high for an Aerohead. Once I get
    a tire on it will drop a bit...

    Those Aerohead rims are light! Only 411g for the non-OC... 98g lighter
    than the CXP21 it replaced.

    Or not... I just spent another half hour playing with it and got the
    variation down to 105kg +-8kg.
