Re: Preventing Motor Stalling
We are also using a bicycle disc brake for our arm, but an alternative breaking system could be used. In 2005 we had a simple but effective breaking system. A very short stroke pneumatic attached to a heavy piece of rubber partially wrapped the output shaft from the gear box (actually wrapped around a cam-like device on the shaft). When the pneumatic was extended the system could move freely. When the pneumatic retracted the arm was locked in place.
I will also second Mike's point that you probably have way more power than you need to move the arm.
