[tim-tim]

We used a piece of .063" 5052 as the curved piece that the frisbee traveled against. To attach this to the top and bottom plates we put tabs (straight) no bends on the curved piece and holes in the top and bottom plates for the tabs. Everything just "snapped" together, and then we threw a few screws between the top and bottom plates to prevent the tabs coming out of the slot.

This was our "simple" solution. This requires some tweaking of a bent sheet metal part in CAD to get to work correctly. Although we were successful on the first part manufactured, the tolerances were about the tightest we could get them. I'll dig up the numbers later on.

We lined the wall with a nonabrasive 3M friction tape; not like a sandpaper.

We wanted to send the assembly to GEICO to let them know that Tab A does fit into Slot B.
