Here I will make a simple chess board out of 3/4” plywood using a Vbit and some black acrylic paint.
Here I used a 60 degree Vbit to cut the 1.5” squares on a 13” board.
I cut this first pass I cut the grooves about .0625” deep.
I used some black acrylic paint to color the dark squares.
I then made a second pass with the Vbit to .08”.
Quick sanding with 120 grit paper.
I gave the board two coats of water based poly.
