bicycle propellor drive

a simple way to drive a prop from a bicycle crank

My apologies for the hideous camera work that so many have noted. I had poisoned myself and didn't realize it with some paint primer that went thru my skin the day before.
I would love having help with editing, that's where I can't seem to get things worked out.
I only leave it up because so many people are looking at it.
For me it is a reminder of a darker time in my life.


Functionally it has worked out pretty well, I made a retractable model that I ran in the 2012 Corvallis KSR. This required two milwaukee drives. The gear boxes gave a 4 to one reduction, to this I added 2 to one gears on the chain rings for an 8 to one over all ratio from cranks to prop. It went really well in the water and I aced that race.

The single box with a long tail shown in the video is probably better for most applications, I just couldn't get the tail around the 4" tire in the rear.

I have videos and stills of this but no time to format it so that it doesn't offend the eye or is redundant or ?
I would be happy to provide it if I could get help with the editing.
Thanks
