If you can't find one, try using a 1/4" wire rope clamp with the legs pointing "up". It's easily adjusted but stays in place when the nuts are hand-tightened. I use one on an Original I've set up for slower speeds. I lined the saddle of the clamp with a piece of vinyl electrical tape so it doesn't scratch the shaft.
