Sorry I didn't finish my reply to you yesterday, Sam. EOU is on the right track.
You have an amazing setup! Certainly one of the best I've seen. You've done everything right, but I'm not surprised to hear the paper wheels aren't running true. I kinda doubt you will be able to clamp the warp out of them, but warp probably doesn't matter as much as concentricity. (yes, spell check constantly needs words added, EOU)
The problem is most likely two fold. The hole in the wheel needs to be a very good fit to the shaft. Sounds like the shaft is metric and the hole is SAE. The two are often close but not close enough for this application. Is there any play between the hole and the shaft, or is it a nice, tight fit?
If the hole isn't part of the problem, or if you have the wheels mounted very solidly and won't need to remove them for any reason, you can fix the concentricity yourself. If you remove the wheels you'll need to true the face again, but it's not a huge ordeal.
Otherwise, you can make or buy MDF wheels to fit your shaft. MDF is stronger, flatter and more stable than paper wheels. James Hammons of Ace Sharpening has specialized experience, and I believe he charges $35/wheel. Pretty sure Mr. Don Bailey uses MDF wheels from Ace Sharpening as well.
