| |  urethane rag joint.
i got tired of that piece of tire mounted to my tire.
so i hit up the urethane supply place for a chunk of 4" O.D. urethane, 80a durometer rod. price: free.
then i went to the metal supply guy and bought a 4" aluminum circle, already cut, for 50 cents.
then i bought a twelve pack and smokes. about 20 bucks.
holesawed, drilled, dremeled, and rebuilt my coaster brake while i was at it.
a few hours later, and the pictures say it all...
(it's too dark, and i've been drinking most of the day, so i haven't tested it yet. i'll let you all know tomorrow...) |

You simply can not beat beer powered engineering..
But if you were sober that thing would have take one half hour.
Instead of all day.

gdang beer overhead can make these bikes soooo expensive 
Nice job! Question tho - usually I see two bits of tire - one on the outside of the spokes and another inside (makin a spoke sammich), it looks as if you have nothin' between the sprocket and the spokes in this pic... is that an acceptable method?
I would think the angle of the spokes would cause problems w/warpage if they get forced to align flush with the sprocket, particularly as the urethane seems to be firmer than the ol' hunk o'tire bits.
but if it works - so be it 
If it's the same bike as in yer avatar - nice job matchin the colors lol

Yeah, I'd put another between the spokes and the sprocket, or you'll be beer bonging away the afternoon doing repairs soon.

there's actually a really thin piece of soft ABS plastic on the sprocket side, between the spokes. i can't put another rag joint in because of chain alignment. there's no spoke wear or nothing. |

why? for the same reason that first kid put a baseball card in his spokes 100 years ago... |
