I've made and given away a couple of chess boards.
Strip and flip refers to making them like a cutting board:
Rip equal widths of two contrasting woods--make them long enough to lose the kerf and still be wide enough when re-cut.
These 8 strips (4 of each wood) must be square, true and plumb--that is, the milling should be joint the face, joint the edge, plane to thickness, rip to width and optionally, final joint the edge for a gap-free glue joint.
Glue them up in alternating strips--dark, light, dark, light, dark, light, dark, light.
After the glue dries, rip across the strips making 8 new strips which are multi-colored.
Now, flip or rotate 180-degrees every other strip and re-glue.
Ta-da, you have a chess board :biggrin:
