Although, I was wondering about the bearing that you used to tension the lower belt, not the 0.75" bearing for the shifter. lol

Oh. For the lower belt, I just used a steel sleeve around a slightly longer aluminum sleeve. The aluminum sleeve had a 10-32 screw go through and clamp to the top plate. Then the steel sleeve was still free spinning, but constrained in place.
You could just use a 1/4" or 5/16" aluminum sleeve and use a 1/4" or 5/16" bearing from McMaster or Boca Bearings. I know 192 used Boca last year for their gearbox gears, but personally I haven't used them.
