Art Dutra brought up a valid concern with putting too many bearings on the same shaft and 'overlocating' it, but I think you could get away with a third bearing on the plate closest to the output side if you used a previously cut plate as a fixture for the next plate so they would be lined up. You're also using hex shafts and hex bearings, which tend to have sloppy fits anyway.

Yeah that's true. I'll go ahaid and experiment with 1/8" thick sheet metal and bearings at our next meeting, and make a little prototype with just the shaft and bearings so that I can apply a load and see how it holds up. Thanks!
