So what did the little collection of tools on a stool look like at the end of the project?
You can see I’ve added a sashigane, a larger ruler, a socket awl and a drilling block. The awl is useful for making a hole where the brad point of a drill bit can go to keep the bit from skating around as the hole gets started. The block keeps the drill bit perpendicular to the surface of the wood as the hole is drilled. The other black plastic thing is a right-angle block.
