Woops, forgot to snap photos of the next step... I'll attach photos of the clompleted pieces.
Cut one 3/4" chunk from your 13/16" dadoed board, one 9/16" chunk, and one 1/2" chunk. Set the half inch piece aside. You'll be attaching the two remaining pieces to the plywood with the 1" and 1.5" arcs.
The 3/4" piece goes with the 1.5" arc. Orient the dado vertically, with the slot exactly 1/4" back from the middle of the arc.
The 9/16" piece goes with the 1" arc. Orient the dado on top, with the piece flush with the arc, extending 9/16" back. Glue these pieces in place and add a stop on the horizontal dado. Add a shim on the vertical dado so that the blank, when seated, sits proud of the top of the dado.

Cut two 13/16" pieces from the 9/16" dadoed board, and attach them 13/16" back from each end on the other plywood piece like you prepared earlier. Add stops like you did on the first piece. For these, they will interfere with the pivot hole, so I made space with a forstener bit and a file.
Trim the hardwood pieces on your bandsaw, and take them to your sander and sand 'em up.

With the 1/2" chunk of the 13/16" dadoed board that you set aside earlier, make yourself a drilling jig, and drill the #29 holes in your blanks.
