Bought this black walnut cookie off of Facebook marketplace for a good price. The only catch is it is warped, cracked, cupped, and twisted. It’s about 4 in thick and that’s plenty of material to make a coffee table, but I need some advice and guidance on making a router planing jig please.
I’m no expert, but I’ve seen better people than me getting boards to nearly flat with only a hand plane.
They’re usually the “back to pre-power-tools woodworking” types.
