Assembly

GA-056 dimensioned assembly
  1. Plan the removable gravel splash-pad border for this result: Keep a shallow loose-stone splash surface in its own removable border beneath a small existing outdoor water discharge. Confirm the design reference before cutting: Border outside 24 × 24 in (609.6 mm square), open bottom. In the drawings x runs left to right, y runs front to rear and z runs upward.
  2. Verify the required stock before laying out these parts: 1 × 3 in board: actual 0.75 × 2.5 in (19.05 × 63.5 mm). Reject split or twisted wood and unknown salvage; thinner stock requires recalculating the joints, not simply using the listed lengths.
  3. Cut and label the finished parts: 2 Front and rear border boards 24 × 2.5 × 0.75 in (609.6 × 63.5 × 19.05 mm), mark P01; 2 Side border boards 22.5 × 2.5 × 0.75 in (571.5 × 63.5 × 19.05 mm), mark P02. Keep saw kerf outside each finished line. Rip only where the finished width is narrower than the actual stock; use a suitable guide and target ±1/16 in (1.6 mm) for ordinary cuts. Dowel triples mean length × diameter × diameter, not square dowel stock.
  4. Assemble a 24 × 24 in open-bottom border with 22-1/2 in side boards between front and rear boards.
  5. Clamp square, check matching diagonals and install two 1-1/2 in screws at each corner, at z = 5/8 and 1-7/8 in.
  6. Install one small external angle brace at each corner with compatible screws that do not project into the interior.
GA-056 dimensioned parts or elevation
  1. Mark drainage gaps centered in all four lower board edges, each 2 in wide × 1/2 in high. Remove waste and round their corners.
  2. Place the empty border on the already suitable landscape splash area, away from structures and paths. Do not excavate, dam a swale or cover a drain.
  3. If a permeable separator is appropriate to the existing site plan, fit it loosely inside without covering the drainage gaps. Add clean rounded stone in a shallow layer below the gap tops only when that does not obstruct flow.
  4. Test a small discharge and observe water leaving freely through and around the border. Stop if water ponds, erodes soil downstream or moves toward a building.
  5. Use solely as a removable stone organizer for the existing splash area. Design of runoff volumes, slope, infiltration and foundation drainage remains outside this small assembly.
  6. Complete the acceptance checks below before putting the assembly into service. Record any changed stock thickness, fastener or equipment fit on the project sheet. The published geometry has not been physically built or load-tested.
