    Picked up this little thing this morning . It's a 1959 CWC Roadmaster . The seat , handlebars , rims and tires were replaced with Schwinn parts . That's ok because in my head I have a vision of a mini higgins colorflow pig bike ? Just started scrounging parts . road master oct4.jpg

    Yes 20" . Does any one know if 26" hubs will fit 20" rims with the
    right spokes ? I have some higgins air cooled hubs I would like to
    try ? Need to find some 36 hole 20" rims first .

    I know that for sure Stars Rims makes 20" with 36H. The only others I'm aware off are the ones used in Polish bikes - Czajka, Karat & Flaming, but those might by hardly available I States

    Also I think that most BMX have 36H rims

    The bike junk man let me steal some 36 hole wheels of from a girls Giant 20" bike . I plan on taking them apart , painting the alum rims white and hoping to replace the hubs with Higgins air cooled hubs ? Fingers crossed ?

    Does air-cooled refer to the holes in the sproket? Thought those were "speed holes"

    As far as relacing goes, I've laced 26" hubs into 20" rims and after calculating spoke length with a spoke calc, (I use Sapim's free online and it's pretty easy to use) I then order the length I need. As long as your redoing them might as well get what you want. Shop around, you can usually get color and gauge you want and nipples to match for not a lot a cash.
    I put a Shimano 3C - 3 speed coaster from a 26 x 1 3/8 wheel into a 20" rim for last years buildoff.

    You have to take the parts OUT of the bucket for effective before and after pictures!

    Sorry. I was being tongue in cheek about the double posted picture of the soak tanks.
    I find the best jokes are the ones where I have to explain that they're funny. Really adds to the timing.

    Wait, won’t the metal bucket reduce the effect of the OA or worse, eat through it?!
    I always used plastic container (kiddie pools are great options)

    I have another question . The Higgins hub I want to use is a
    skip tooth and I read on the Cabe to make the 1/2 x 1/8 chain ring match , you just cut off every other tooth . Anybody else tried this ? I have a skip tooth chain and the small
    chain ring looks just like a higgins .

    I've done the grind-off-every-other tooth on a couple bikes. It works. It's not ideal tho. The modern sprockets are narrower and the skiptooth chain tends to walk back n forth a little, making some noise, and a sensation in the pedal. It's not terrible tho, and I've logged some miles regardless on that setup.

    WARNING : Do not try this at home . I let the parts bake in the OA bath for 4 days . It burnt some of the chrome and removed alot of paint . The galv steel tank left a green hue even after soaking in baking soda and dish soap . The good news , not much rust left .
