My experience on S.P.A.M. working on our gearbozes for all four years of high school, we've always used 1/4" Polycarbonate sheet. Also we've used 1/8" Aluminum as side plates. Now for the bearings, we used an Arbor Press to push in the bearings into place. In 2002, we used pins. Let me tell you something. You're bound to lose pins if you have to conduct maintenace work on your gearbox (provided you're taking it apart) and they break a little too easily. In 2003, we used screws instead and it was much better, much better for us who had to put and maintain the gearboxes. It facilitates maintanence.
