Paul, That is a very well executed project! Thank you for sharing this. It must be a real hoot to see that thing moving!

Got an idea for you if I may. When you cast your sprockets or anything for that matter it might makethem even tougher if you put in bits of carbon fiber...kinda like rebar. The guys who do model subs use this in the control surfaces to give them that little extra strength.

Terrific job!!
