Truing/Balancing Paper Wheels

[EOU]

Here's what we would start with Sam; set something on the work table or attached to the grinder body as a fixed point that is an 1/8th" or closer to the wheel surface and spin the wheel. You get the picture already. Watch the gap between fixed point and wheel surface narrow/widen so that at least you can tell how great the error in concentricity  (our spell checker doesn't like this word) is. At least then you'll know what you're dealing with.
