dev,
Just guessing on this, but have been a confirmed "fix-it" guy for years.
My guess is that a fan motor just wouldn't have the power needed to use for a spinner. Would probably need at least a 1/2 horsepower motor for that and I don't think a small fan would have nearly that much.
Probably need something like a washing machine motor or something along those lines. Something with a lot of torque. Might be able to find one at the appliance repair shop for cheap, maybe.

You must face it.
