How can I attach a crank like this to a motor like this?

kf2qd:
Any hobby shops near you that have Model Airplane supplies? They have thins like small shaft collars that are made of brass, and brass plate. You could solder the shaft collar to a piece of brass plate and then (using the set screw in the shaft collar) mount the crank to the motor.

Hey guys - nice of you to offer useful answers and ideas to the question that was asked.... Try to be helpful, not just geniuses...

You interpreted differently than "we" did.
That's OK.
If he wanted to do it like the picture, we gave our take on that ("Improvise, that's how we won the war.")
Anybody can go spend money.

I heart JBWeld !
