This was I little project that I did recently.
I swapped out the plasma torch on my cnc plasma table for a router, and taught myself the programming to complete the sign. I had been wanting to try this ever since I got my table, and was finally given the opportunity when a local graphic designer came knocking. After some heavy thought, I got the router mounted and VERY slowly figured out how to make the program run the router.
The circle with the bird in it, is 1/4” hot rolled steel with a beeswax finish, and is flush with the surface of the wood.
The text near the bottom is 1/8” hot rolled steel, and also beeswaxed and sunk flush into the wood.
