Assembly

GA-026 dimensioned assembly
  1. Plan the removable drip-tube payout spindle for this result: Unwind a lightweight coil of flexible drip tubing by hand while keeping the coil on a central spindle. Confirm the design reference before cutting: Axle rotates freely and both retainers stay outside cheeks. 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 × 4 in board: actual 0.75 × 3.5 in (19.05 × 88.9 mm); 2 × 2 in board: actual 1.5 × 1.5 in (38.1 × 38.1 mm); 1/2 in dowel: measured diameter 0.5 in; measured 3/4 in plywood: measured thickness 0.75 in. 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: 1 Base 24 × 24 × 0.75 in (609.6 × 609.6 × 19.05 mm), mark P01; 2 Upright cheeks 18 × 3.5 × 0.75 in (457.2 × 88.9 × 19.05 mm), mark P02; 2 Foot cleats 12 × 1.5 × 1.5 in (304.8 × 38.1 × 38.1 mm), mark P03; 1 Axle 24 × 0.5 × 0.5 in (609.6 × 12.7 × 12.7 mm), mark P04. 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. Place cleats on the base at x = 1-1/2 and 21 in, y = 6–18 in. Fasten each through the base with four 1-1/2 in screws.
  5. Stand cheek boards inside the cleats, at x = 3–3-3/4 and 20-1/4–21 in. Their lower ends rest on the base.
  6. Fasten each cheek horizontally through its 1-1/2 in-wide outside cleat using four #8 × 2 in screws in a staggered pattern. The remaining 1/2 in enters the 3/4 in cheek; verify no point emerges. Predrill and keep the cheek at the stated 18 in reference height.
GA-026 dimensioned parts or elevation
  1. Mark axle centers on both cheeks at y = 12 in, z = 12-3/4 in. Clamp a drilling guide so both 9/16 in holes align.
  2. Drill the aligned holes and sand them smooth. Slide the 24 in, 1/2 in-diameter dowel through both cheeks without force.
  3. Fit the actual lightweight tubing reel on the axle between the cheeks. Its width must be less than 16-1/2 in and its diameter less than 23 in to clear the base.
  4. If using loose tubing, fit two 12 in reel discs on the axle against the coil and retain them with collars; list these discs as auxiliary circular parts, not an assumed rectangular offcut.
  5. Install end collars outside both cheeks and pay out tubing by hand from a short distance. Stop if the base lifts, the dowel bends or loops snag; do not pull with a vehicle or pressurize tubing on the reel.
  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.
