<DIV>That's exactly what I've got on Snoopy. I just made the hub to slide over the motor can. Then make a thin longitudinal cut, but just along one side. The cut need only offer a very tiny movement for it to clamp tight. I have made two that way, and you can tighten either with integral bolts or just putting screw-driven hose clamps over the hub. The one thing I'd also suggest is making the hub cylindrical instead of the nice tapered section you drew. Not that I don't like it, but fabrication would be a bear. If it were me I'd make the hub out of pipe, not milling it which is what the those curves seem to imply. You can use a piece of pipe and chamfer the angles to make is a little smoother...<BR clear=none><BR clear=none>
