Tools: Jigsaw. Materials: Plywood or project panel, 3/4"
Trace and cut the base into an arched shape with a jigsaw — go slowly for a smooth curve, since this is the most visible cut in the whole build.
Tools: Drill / Driver. Materials: Pine, 2x4, 24 in, Wood screws, 2"
Attach the 2x4 upright to the base with 2" screws (longer screws work too — 2-1/4" just matches what's needed in the next step).
Tools: Drill / Driver. Materials: Pine, 1x10, 16 in, or plywood scrap, Wood glue, Felt pads
Attach the backboard to the top of the 2x4 with 2" screws and glue. If the finished base doesn't sit flat on your floor, add felt pads underneath to slightly elevate and soften the contact.
