Very cool. Is there something along the lines of your split bung available on the market? I have a couple old frames and am working as a welder this summer for
an artist friend of mine. I'd love to try my hand at this.

Next time this comes up, mention that a blower belt for a dragster can easily put up with four-digit amounts of horsepower. Granted, it's much wider, but even so, there's no way your legs can do anything to a belt at 1/8th the width.
