gear system
- 9.6 est small diameter ?? . (15 teeth?), 5mm more
- ~25mm diameter - (40 teeth), 6mm bore
- w/belt 26.32mm diameter
- 35 mm spacing
- current ratio ~2.5
- large pulley radius could grow by 7.3mm (abs max) - although part of the pyramid is in the way. lathe to fix that.
- 39mm pulley has 62 teeth - for a ratio of 4.13!
