Greetings, all fellow backyard-welding pedal pumpers! (Gosh, that sounds corny. But it will

This may be of interest to many who build human powered mutant bikes and other light vehicles.
Between Burners and Kinetic Racers, and the occasional other Clever Inventor, there seems
to be a steady demand for adaptors to install bicycle freewheels on plain round shafts --
or actually, I suppose, shafts with keyway, so they actually work.
We have found a source -- a bicycle oriented machine shop that has made these before.
Pricing depends on quantity. A realistic quantity is 100 pieces. I was quoted $11,- without
keyway. The keyway would add quite a bit, and then there is shipping and whatnot. So, being
grownups, we should probably brace for $15 - $20. I cannot afford to give away a
Grand or two, but I can front the money and distribute them at my cost.
