I had to do about 100 small pieces similar to those for a guy wanting to display a coin collection. After doing the router work around the outside I drilled a shallow recess into each to hold the quarters and half dollars in his collection. I did them with maple and used a ogee bit to put some shape on the outside. Of course holding them while using the router table was an issue. I made a holding device from a scrap piece of MDF and cut it so that the blanks had to be forced (slighty) into the pocket that I had cut out to place them in while routing. In other words I cut out a square in the end of the MDF that fit the blanks tightly. I placed another small piece of 1/4" plywood over the top of the cutout to hold the pieces down firmly while the routing was done. That way the piece couldn't raise up or have a chance to come out of the jig. It was slow going since I had to remove it and reposition it 4 times to get just one block done but the operation was a success. It yielded enough pieces without tearout to make the collection display.
I once heard that cats and women will do darn well what they please and that men and dogs would do well to accept it and just go on.
