Before you build another rolling machine, try rolling the strap so it
makes a spiral that is close wrapped. ie the coils touch each other.


Dan, how would you do that with a roller that had bearing bosses at both
ends? The spacing would _have_ to be at least as wide as the thickness
of the boss.

The only way I see achieving that end is with cantelevered rollers.
