Now that is a great idea to put the groove in for the cover. I'm filing that one as an addition to the boar I made last month for my sweetie. Great use of the different species to add the visual interest. Thanks for the post and the idea!
I used a Jasper circle jig. Instead of drilling a 1/8 inch guild hole, I took a piece of 1/4 plexglass and made a 3 inch circle. I drilled a 1/8 inch hole in the center of it and fasten it to the board with 2 sided tape. I then took a small piece of plexglass and attached it to the front of router so it would sit flat.. now cut groove.
