I'm suddenly thinking about one of the first N Gauge locomotive.

Yes.... the rubber band driven Lone Star locomotive.

Well I really had to push things to get it that fast.. at 200rpm with the nail, the speed was pretty reasonable.. I just wanted to see of the idea would work.. and it did..

FWIW..
Video 1 was 8.3 Smph
Video 2 was 35.75 Smph
Video 3 was 384.9 Smph

@learmoia , thank you for the proof of concept.  I will be mounting mine on a stick and putting the stick in a heavy drill press vise- Don't think i will have to bolt it down, but I can if I need to.
