Del's peg & slot rotary drive with wooden chain

Del never ceases to amaze me with the amazing wooden machines he has built over the years. This one features a nifty drive made up of two discs -- one large one and one small. The large disc has a grooves cut into it that run from the center to the edge. The small disc has thee protruding pegs that engage the grooves and drive the larger wheel. Also of note are the nice wooden chains and sprockets -- one with a chain tensioner!

It's interesting how the output velocity appears to be constant but I'd expect the output torque to change as the pegs move from the inside to outside of the larger disk.

I'd recommend all chain systems where the output load can change should have a chain tentioner otherwise the chain will jump off the sprockets.
