Picnic Table That Converts to Benches

Cut list makes TWO benches that convert to ONE picnic table. Before lumber: the source builders found this most comfortable as a bench — the wide seat is great to sit on and slightly awkward to swing legs over in table mode. Mostly-table users should build a conventional picnic table; mostly-bench users are in exactly the right place.

Drill a 1/2" hole centered near the top of all four back legs. Drill straight — these are the axles the whole transformation swings on. A drill press is nice; careful freehand with a speed square sighted from two directions works.

Lay a front leg over a back leg's bottom, edges flush, and trace the front leg's top edge — that line locates the seat support. Glue and screw the seat support across both legs with 2-1/2" screws.

Build two with the support on the RIGHT and two on the LEFT. The plan bolds this because someone always builds four identical: each bench needs one of each hand.

Mark the seat boards 2" from each end (the overhang past the legs), then screw three boards per bench to a left and a right leg assembly, 1/4" gaps, glue and 2-1/2" screws. Square each bench by matching diagonals before the final screws.

Screw three tabletop boards across a pair of 17" 2x6 tabletop supports, same 1/4" gaps and 2" end overhangs as the seats. Drill a 1/2" hole in each support's lower end to match the back legs' pivot holes — each half will bolt between its bench's back legs.

Line up each tabletop half's support holes with the back legs' pivot holes, thread the 4" bolts through with washers, and snug the nuts — snug, not crushed; this joint rotates.

Rotate the top flat, clamp it, and lay the level across perpendicular to the boards. Level? Drill a second 1/2" hole through leg and support together and drop in a pin bolt. Both sides. Those in-place holes are why the tabletop will sit flat forever.

Pull the pins and rotate each top up into a backrest. SIT IN THE BENCH and adjust the angle until it's genuinely comfortable — this is a decision your back makes, not the plan. Clamp, drill the third hole through leg and support, and pin it.

Converting is now a ten-second job: pull two pins per bench, rotate, re-pin.

Screw the 41" bottom back support across the back legs, 6" up from the leg bases, two screws per end — it keeps the legs from splaying under load.

Sand hard (hands grip these edges every conversion), finish exterior-grade, and label the pin holes discreetly if houseguests will be doing the converting. Building longer? The source shows an 8-foot version: full-length boards, a third center leg assembly, and an added back brace.
