I was thinking of spinning it a few times by hand and waiting to see which side ends up at the bottom. The problem with this is that the axel bearings are a little stiff, so this method may not be too reliable. Any cool ideas out there? I'm hoping to have time to fix it during our Lonestar Regional, you know how much free time there is! Or maybe we should just call it our ball agitator/shooter  |
I'm sure the wheels are held at the manufacturing plant for them to some sort of trueness, but the higher RPM they spin the more you notice imperfections.
The wheels you are talking about were probably designed to go way slower than you are spinning them. How many wheelchairs do you know that have the front wheels spinning 20+mph? lol
Anyways, keeping that in mind, check your pillow block or whatever you are affixing it to your frame to. Make sure they are aligned right. One .050" difference in center lines of the block from the X axis will make your wheel wobble a heck of a lot at these high speeds.
