Step 1: Mark the two side pieces
Use a tape measure to swing arcs for the edges as shown in Figure A, then mark the holes for the pivot screws and the back dowel stop.
Begin by cutting the two sides to length and laying out the boards (Photo 1 and Figure A). Note that the sides will be mirror images. To mark the curved sides, hook your tape over the lower corners then swing 15-in.-radius curves on each side. Use a pint can to create the rounded inner edges of the legs. The positions of the pivot and dowel holes are critical, so measure carefully. The pivot hole goes all the way through the board, but the dowel holes are only 1/2 in. deep. Drill the holes, then use a jigsaw to cut out the parts. Use a 1/4-in. round-over bit or sandpaper to soften all the edges.
Step 2: Assemble the stool with 2-in. screws
First screw the back brace to the bottom shelf, then secure this L-shape assembly to the sides. Drill the holes for the pivot screw and the back dowel stop.
Connect the 1×10 bottom shelf and 1×4 back brace to create an ‘L.’ Secure this assembly to the sides so the top edge of the 1×4 is flush with the upper back corner of the sides. Use 2×4 blocks to ensure the right spacing (Photo 2).
Step 3: Install the back
Screw the back to the pivot arms to create a U-shape. Drill the holes in the pivot arms, then secure the back using 2-in. bolts, washers and nuts. Don’t permanently fasten the top until you’ve ‘test swiveled’ the back to make sure you have enough clearance.
Cut the three parts for the back assembly (Figure A). To create the curved back, drive a pair of finish nails 3-1/2 in. from the edge of a 1×6, and flex a thin piece of wood upward between the nails to create an arc. Mark the arc with a pencil, then cut it out with a jigsaw. Secure the back to the two 1×4 sides to create a U-shape. Use 2-in. bolts (Photo 3) to secure the back assembly to the sides of the stool. (Tip: To install the washer between the back assembly and the stool, tape it over the hole in the side before installing the assembly.) Finally, position the top far back enough-about 1/2 in. from the front of the sides-so the back doesn’t hit the front lip as it pivots.
