Brake band is in progress. No time right now. This was one of the reasons for the tear down. Now I have the machining done on the main frame to attach the necessary parts. I was going to use servos to actuate the clutch and another to set the brake. Changed my mind because I think a servo will burn up if the clutch doesn't shift exactly as it should without binding. And if it binds, I can't hear or see it with all the outside noises at shows. I am experimenting with some lineal and rotary solenoids.
