How about this: consider a 'normal' bubble etch tank. Rather than
having two clips on a board attached to something at the top of the
tank, have one clip attached as usual. The second clip is attached via
a length of fishing line to an arm mounted on a motor. By using a
pulley system, the motor wouldn't necessarily need to be too close to
the tank.
Microwave oven turntable motor?
