Hi Dan
I think I would stick with the plastic

BUT hears one more ideal pickup some 1" thick plastic drill out the center hole and the mouting holes then drill out the holes for the plunge rods then just drill the holes for the roll pins drive them into place and your done without using any glue

1" x 9" x 9" acrylic plastic should work just fine for this one.
Also, I think I would pickup the item(s) below just in case you need to get the bit higher in the router table.
