1

Lay out the legs and top. Rip the plywood into 18-in. and 6-in. strips. Draw “crosshairs” on the larger piece, drive a screw in the center, hook your tape over it, then with a pencil snugged against the 7-in. mark, draw the circle. Cut four support blocks from the narrow piece.

2

Cut out the parts and rout the edges. Use a jigsaw to cut out the parts (see Figure A), then use a router with a 1/4-in. round-over bit to ease the edges as shown.

Assemble the stool. Screw two triangular blocks where the top layout marks intersect (kitty corner from each other), then secure the legs using 2-in. screws. Install the other two blocks, then apply a finish.
