Azathoth had an idea of adding "flywheels", so I added rollers, and I think this will work quite well. I think this is what he wanted.
I think if I am to add bearings to this design, it would increase cost by quite a bit (relatively), but I suppose it would be good for slippage>>consistency.
Added two more "rollers". I think this would work very well, but I'm concerned with the little empty areas between the rollers. This could be either solved by using many tiny rollers or design some sort of belt system... but this is seemingly increasing too quickly in complexity for me :P. I suppose people would want the rollers to be made out of delrin :P

Added a belt. I expect rubber bands should work
Yeah, after seeing the ptw hopup, I would need to get rid of the bucking for this to work correctly. Looks like I'm going to have to test the concave vs flat plate designs now.
Edit:
I'm hoping to have "alpha" and "beta" testing done by the end of the summer, and will try sending a few out for testing. Depending on performance (compared to stock and SCS/PCS) I'm expecting the price to be around $5ish for the flat/angled plate and $10ish for the concave nub (concave nub will take 2-3x longer to cut). I'll design a second set that will fit into the vsr-10/bar-10 series SR's and we'll decide from there what to do next.
