A variation of the Aircraft Carrier challenge coin display inspired by photo’s on here and elsewhere on the internet. This one is made from walnut and is 30” long by 10” wide. I have another order for one similar that will be made of Teak and 40” x 10”. I’ll be nervous with the pricing on Teak…but after two of these I think I have the hang of how to manage the CNC through the process of carving the coin slots.
If you are interested, I carve the board flat first and use a v-bit to just slightly mark where the coin slots will be. Then I put the board on the bed with a 15% wedge under both ends. I then move the tool (1/4” core box bit) to the start of the first line and set the x,y and z coordinates to 0. A tool path is created the uses the same lines used in the initial layout but they are individually moved in the program to start at x=0 and y=0. After the first line is done, I re-position the tool to the start of the next line and repeat the process. It’s actually pretty quick and allows me to not have the slots come out on the ends of the board.
