Earlier this week I got my first flat tire on my stock
coker. When I arrived home from work that evening I had only
intended to fix the flat but before I knew it the entire
wheel had been unbuilt. It was almost like I was hypnotized
into rebuilding the thing.
I had a Schwinn type hub that is considerably wider than the
stock hub. I decided to use it instead.
First problem. The spoke holes in my new hub were too small
for the coker spokes. This was remedied with the help of a
handheld power drill and a 1/8" drill bit.
The wheel went back together without any problem. There is
almost no extra space between the crank/frame/hub
intersection. Very close quarters. In fact, it almost looks
like the frame is now rubbing on the hub. Only after careful
examination did I determine that nothing is actually
interfering.
I began tensioning the spokes and the rim is reasonably true
(given the limits of the cheap steel rim).
After reading a recent post by John Childs I became nervous,
however, that I have over-tensioned the spokes.
Is there an convenient, objective way to determine what
is "too much"? What is the effect of over tightening
the spokes?
I remember from many years ago when mountain biking was just
beginning to be popular there were several companies that
were creating mtb rims from road rims that were cut and re-
rolled down to a smaller size. Has this been tried in
reverse for coker rims? For example could you take a couple
of Alex DX-32s, cut them and carefully roll them out to make
a 36" rim?
Also, is the airfoil (?) rim available separately
somewhere? How much?
Thanks,

P.S. I eventually did patch the tube. :-)
