<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto"><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><br><div><br></div></div><div><br>On Nov 1, 2013, at 8:25 PM, hank pronk <<a href="mailto:hanker_20032000@yahoo.ca">hanker_20032000@yahoo.ca</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12pt"><div><span>Joe,</span></div><div><span>I would make the hub from one piece of material instead of two.
