Why this kit
Full-circumference lip lids seal well and open badly. Keep the lip locked on the pail; open a cut panel instead. Pair with an intact shell for collection, or with the rack bucket shell for modular and municipal banks.
What you build
- Sub-lid panel — largest opening the stock lid allows (≥25 mm land to the sealing lip; keep needed ribs).
- Molded features — keep stock handles/grips on the free edge opposite the hinge.
- Hinges — two strap hinges on the edge that hangs open by gravity when the pail is tilted on a rack.
- Optional string or light latch — only if there is no useful molded pull.

Materials
Gather these before you cut. Optional items use unit optional.
| Qty | Unit | Item | Spec | Notes |
|---|---|---|---|---|
| 1 | each | Stock lip lid | Original circular lid matched to 5-gal (19 L) food pail | Gamma / snap lids OK if same cut rules; practice on a spare; keep molded handles when present |
| 1 | each | Sub-lid panel | Cut from same stock lid — largest opening lid permits | ≥25 mm land to sealing lip; molded handle opposite hinge when present |
| 2 | each | Strap hinges | 40–50 mm (1½–2 in) with screws | Hinge on rack bottom-of-face edge so panel hangs open when tilted |
| 1 | optional | String pull | Cord loop through free edge | Only if no useful molded grip; kitchen lift + rare wind tie |
| 1 | optional | Light latch | Toggle / barrel bolt / small catch | Not a padlock; stop wind/chickens only |

Build guide
Mark, cut, hinge, and tune steps—including safety—are on the full build guide (HTML; works offline in the PWA). Print that page or any schematic from the browser for paper.
- Seat the stock lid on an empty matched pail; note molded handles; mark the largest panel with ≥25 mm land (handle opposite hinge).
- Cut the sub-lid; deburr.
- Hinge on the rack bottom-of-face edge; confirm gravity-open when tilted.
- Use molded pull if present; else optional string or light latch.
