My mini fcg motor died and I needed to find a replacement. I thought I would try and use the little vent motor from one of the surplus houses for $2.99 plus shipping. I got 8 of them so here is another way to use it. I also slowed it down with a 9 volt battery. It runs close to 3 rpm. It's been running for 4 hours and still going! I need to put in a brand new battery and see how long she'll run. I really like these little motors. To mount the crank, run a 1/4-20 tap down the center of the motor shaft. It goes pretty deep which is a good thing. Tap it to the bottom. Cut off a length of 1/4-20 allthread and run it to the bottom of the shaft. Put a nut on top and add your crank arm. Easy peasy. Oh, the ghostie was purchased a couple years ago at Walgreens. Just added wire arms. click the pic!
