12" I3V Build

So the bearings in the delrin wheel measure 11mm. The bearings by themselves measure 10mm. The washer they came with is 0.8mm. Add a 0.2mm clutch bell shim, tighten down nice and firm and it turns completely smooth, no binding at all. Two teflon washer from the slash are a little thicker than 1mm and seem to compress. There was no binding but not as smooth as the metal clutch bell shim. The precision 1mm washers recommended above are highly recommended. Colin should be sending these kits out with those. I'm not going to wait for them as I can get enough 0.2mm shims from a local hobby shop that's minutes from my house.
