well the aerobic thing is out as i found out he has no sweat glands (only on his butt which didn't get burnt) and has to monitor temp always.

looked @ the cart this weekend. 3turns lock to lock, using a rack/pinion connected to a bell crank. not alot of effort to turn.
my thinking is a linear actuater connected to the bellcrank would be real easy but the duty cycle and the fact that it would not be easily converted back to manual operation is a concern
coming from an automotive background i thought about splitting the mast jacket, adding a sprockett to the strg shaft, sandwiched between 2 collars and a chain drive to a wiper motor or window motor. bushing the driven sprockett and securing with a removable pin or a gear dog. that way it's easy to change for normal steering.
fab a footpedal w/springs and stops to control range and effort. weld 2 pieces of bar stock forward and aft of center to operate a windlass sw (reversing sw)
other issues:
old style dimmer sw mounted on firewall (w/lighted indicator) for on/off.
makeup for/reverse arm, hanging down w/handle for leg control
lengthen the existing rail on driver side of seat and adding a safety net from rail to roof (driver unable to fasten seat belt, etc) enter from pass side
what do you think, too easy?
