I know this is an old thread, but I'm eager to see if you have any updates for us. I'd love to do this with my SE.
BTW-It may be just the cobwebs in my mellon talking, but I seem to remember there being a belt conversion on the market for these Yokes back in the day. I remember it being EXPENSIVE (believe it came with a new chassis, center brace, etc) and tempermental. Like I said. May just be my faulty memeory mixing things up. There were of course later belt drive Yokes, Optimas, and there was a belt drive conversion for the chain driven Optimas.
Soooo..............any progress???
