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.

I thought the whole idea behind CNC was you could set up the job so as to not have to ‘reset’ the starting points over and over again. Why would the lines come out of the end of the board if they were not programmed to?

Well, I suppose I’m still at the intermediate stage and didn’t want to try and figure out how to create the 3D model of the flight deck at the 15 degree angle. This didn’t take very long and I’m happy with the approach and repeatability. As for coming out on the ends…I just meant that using the CNC allows this vice the table saw method I’ve seen.

Thanks for your service on Connie :) I came a bit behind you but walked the decks on Kitty Hawk and served on NIMITZ and ABRAHAM LINCOLN!

Great looking Challenge Coin display! It looks great in walnut, and your CNC work looks spot on.

I’m sure whomever receives this will really appreciate it!

(By the way, teak is danged expensive these days. You can find other exotic woods at lower prices.)

Looks great! I only have ONE piddling little challenge coin, but still… there’s only one guy in my ‘hood who I might run into with HIS coin, so I need to be prepared, not in a display, but in my pocket!
