I made a hardwood sign for a birthday gift on my CNC recently. I use an X-Carve for my wood CNC work and for this sign chose walnut as the base material and a 60-degree v-bit to carve the letters. I imported the logo and used a font in V-Carve, but the same could have been done in Easel Pro, which is what I use as my cut driver/interface.
I have outlined all the steps I take in making a single color hardwood sign, but an additional color or colors would use the same process. To do a sign carving on a painted surface, the process and materials are completely different, so if you use my tape and paint method, your results will vary…
