There is a need for me to change ratios on the PedGen as is... it is almost
right for charging 12 volt the driven wheel is not the ideal way of delivering the Power
tho so I'm going to make 3 pulleys on the same shaft ( 3 round discs of 4x2)
1. 4'' diameter for 12 volts
2. 3 1/2 " diameter for 14.4 volts
3. 3" diameter for 18 volts .
the shaft of the EMC is about 6 inches long ...plenty of room
for all three pulleys.
Shifting pulleys will be a simple matter of sliding the EMC
so the appropriate driven pulley is engaged underneath the drive wheel.
The seat also requires a different arrangement.
and in the meantime I'll have to finish Tom's PVC 14.4 cordless drill pack.
