Oneway wheel balancing system
First off, I apologize for not having pictures. Anyway it arrived last week, and was surprisingly easy to set up. Follow the directions, and its no problem. It took me less than 20 minutes to complete. After balancing, it is amazing how much longer the wheels spin afterward, due to being more properly balanced. There's a slight increase in noise of the grinder, due to the spinning nut/washers on the flanges which screw onto the grinding wheels, but it is pretty negligible, and I wear ear protection constantly while in turning mode. The difference in sharpening is pretty amazing. While overall noise is increased, the sound of the tools on the grinding wheels is noticeably different, and the tools come out with a VERY increased sharpness. The burr on a scraper is noticeably different, and the edge of gouges is noticeably "brighter"---the striations from the grit are more even.
It was worth the price.
Balancer may still be needed
Be careful about removing the wheel balancers from your grinder. My old washers caused a large portion of my previous vibrations. If you have good backing washers for your grinder, you shouldn't have a problem removing the balancer. If not, like me, you're better off leaving the balancer installed, which provides you with the precision machined washers that are also necessary for vibration free grinding.

Bushings for 1" diameter holes
I just want to add that if you are using a wheel with a 1" hole, such as the Norton 3X, the appropriate bushing is:

the steel drill bushings [headless] [outside diameter 1", and inside diameter 5/8"] is the right size for most grinders. they make a huge improvement!
