Anybody ever make a home-made wheel balancer or know of plans to make one. I can figure out the "A" frame and the center piece for the hub to sit on and the Bullseye level (which I can get at Home Depot ), but am trying to figure out how I should make the wheel "float" separately from the "A" frame to determine where the weights should be put on the wheel. Will be willing to settle on some other design if it is feasible. Seemed like a good and functional home project. Thanks all.

The A-frame should have a point on top. The floating hub should be cone shaped to selfcenter the wheel and have a center point inside that will set on the point of the A-frame. The contact points should be above the center of gravity of the hub.

If the hub is made accurately and balanced, these can be very accurate up to about 60mph.

Here's a scratched out drawing of a design I used years ago.

here's a link to one that is available here in Canada. It is the same idea as CCWKen's. http://www.princessauto.com/_osn.cfm?CTRY=CAN&output=OSN&SRCH=1&SRCHAREA=OSN&T1=PORTABLE%20WHEEL%20BALANCER

Here's the same thing sold by Harbor Freight. The spring loaded ring around the cone is used to make sure the wheel is sitting level on the cone (hub).

Not a wheel balancer in the sense you might be looking for but, here are some links to a few pics of a static balancer that I mocked up to test rotating assembilies. After my intial design I have a few changes I plan on making on the next one I build. This setup allows the balancer to accomodate odd shaped parts ie 2 different end diameters. It has one leg that adjusts up and down the other in and out. I plan on making the wheels larger and changing to a higher ABEC rated bearing. As you can see in the pics I was playing with crankshafts on it. Although not as good a dynamic balancer it sure is better than nothing at all and can be used on anything that rotates . . .

Thanks guys!!! You have all given me some great ideas. I am still doing the homework. I think I may lean towards using the "A" frame with centerpoint at the top, and the floating hub on top of the center point for the wheel to rest on. The main thing is that the tire needs to balance freely. This is a relatively small job. Just wanted to get the details straight so I do not have more junk sitting around waiting for me to figure out what to do next. Thanks guys.
