Motor Question

[TVsCHACHI]

Has anyone ever messed with Tudor/Miggle motors and Tudor/Miggle boards, say adding another motor to a 620 and connecting the unit to one switch. I'm sure this is possible, but I'm no electrician. Is it cheaper and/or more effective to buy or make a new motor?

I have some boards in my closet that don't run so well, which I've been saving for the parts, should this work.
