For the wobble plates, I don't expect the plastic to hold up very long at all, but if you have the ability to cut plastic ones easily you may be able to iterate with them until the fit is just right, so you know what dimensions to use for the aluminum/steel versions. Also, will the metal versions be laser cut? I'd be curious if there is any kerf angle as a result of lasercutting that might affect the interface to the rollers. With such tiny pins, the tolerances on all of the parts will probably have a big affect on the performance.

I'm really interested to see how the final one performs! Maybe you could set up a simple bench test apparatus (turn a pulley to wind up a weight, for instance) to test it under different loads. Data is useful!

Pics of the inside have been uploaded to CD. If you want more specific pics I can get them.
The plastic ones are already wearing out a ton, but I do need to use them for iteration. The lasercutting seems to be accurate to +/-0.001" with almost 0 kerf angle, so I get realistic predictions of what metal ones will do from it.
The metal versions will be CNC'd for now, and wire EDM'd hopefully for the final version.
