wheel adapters
 

i was sitting here looking at the wheels from the muscle machines today, and i had a thought.if you could make a back for the wheel, out of say aluminum or a hard plastic, and put those on the axles and spindles, you could interchange the outer wheels, like on the zip zaps.now the machine shop where i used to work, would probably cut me a decent deal on making a bunch of these.and i was wanting to see how interested anyone would in buying sets of just the adapters.any takers?

how much, sounds kool,

it all depends.if i can get like 10-15 sets sold right off the bat, then, i'll see what kinda price i can get.but you're probably looking in the 15-20 range per set.
