I'v also thought of wall clocks as a possable 1rpm/1rph motor, BUT, they have no torque at all. The syncron motors from www.hansen.com have at 1rpm about 30 inch/pound of stalling torque. The 1rph even more. They also have several choices of output shafts, versus a wall clocks needle shaft.

I bought a syncron 1rph for $19.95+ s&h=$24.00.
Very happy.

Would it be possable to do a follow up article aimed at that segment of the hobby as...
