I’m building what amounts to a pitching machine for the Great Ball
Contraption. In most TECHNIC building you’re building a gear train to produce
lots of power at the expense of speed. But in this case I need to build one
that has lots of speed and not much power.

You might also use a fast 2838 motor http://www.peeron.com/inv/parts/2838c01
to direct-drive the ball throwing wheel. A friend used this setup in a GBC
module http://gallery.freelug.org/SummerAFOLDays2005/PhiloReims200527
that worked several hours without motor problems.

Hmmmm. I have but one of the ungeared 9V motors, and I’m using it in a ball
pump, but I will try swapping motors.
If I geared it up just a bit to handle the 90 degree angle (8-tooth gear to
24-tooth crown gear), do you think that would be dangerous?
