    A Pedal-Pushing Drive Build

    Yes, it returns to off if you release it. What I've noticed is that when squeezing the brake handle it's easy to accidentally roll the throttle grip, since it's what you are also squeezing against. Perhaps a twist throttle grip that is not the full width of the handgrip would help a lot. I...

    Good ideas on throttle control from Amberwolf and Malcolm. Your comments inspired me to look at the Alltrax throttle control program. By dialing the ramp-up rate (starting) to min, and the ramp-down rate (stopping) to max, the control is less hair-raising. I'll experiment with the curve that...

Even with the Alltrax controller set to limit at 60 Amps, Joules can exert about 400 lbs on the pedals from a stop, or input...

    Hi Guys, Thanks for all of the great replies to Joules so far. To answer some of your questions: --- The build was motivated by a couple of things. One, I wanted to see if I could regain a few shop skills. The last time I had touched a mill was during Nixon's first term. Second, I was...

    A Pedal-Pushing Drive Build

    Hello All, This is my first post, having discovered this forum about halfway through my project. The craftsmanship and ingenuity of the folks here is stunning. After watching the many creative and well-executed solutions posted here I hesitated to share my own "non-hub drive" with such a...
