I, too, am not an engineer by any means. Wouldn't high enough RPMs compensate for less mass in the drive train? So long as we aren't just ramming a piece of lumber into the blade, anyway...

Later, I'll have to post some pics of the wheels I have thus far. For now, I'll leave you with some works by other people that have been part of my muse.
