Round Epoxy Beach Table — 90 cm
by Makeit_official
Build a 90 cm round coffee table with a thick laminated oak rim that doubles as the casting mould, filled with a real sand-and-pebble shoreline and layered teal epoxy ocean polished to a glass finish. It is for a patient maker with basic woodworking tools who wants a showpiece piece of furniture and is willing to work slowly through multi-day epoxy cures.

15
Small shells
a handful of small flat shells, optional (scattered accents near the waterline)
5
Epoxy Ocean Pour
Slow-cure casting epoxy resin
9–10 kg resin plus hardener combined, low viscosity, UV-resistant, 24–48 h cure (seal coat, three ocean pours and the flood coat)
215
Epoxy pigment pastes
set of four: teal, turquoise, deep blue and opaque white (ocean gradient and wave foam)
33

PLAN, MEASURE AND SET UP
- ✓Sketch plan with all key dimensions
- ✓Measure tallest pebble and record
- ✓Confirm resin maximum single-pour depth
Instructions
• Oak rim: 16 segments, each 38 cm long × 10 cm wide × 20 mm thick, both ends mitred 22.5°. • Base: one birch plywood disc, 90 cm diameter, 18 mm thick — stays as the permanent underside. • Finished geometry: 90 cm outer, 72 cm inner cavity, 40 mm deep; resin surface ends 10 mm below rim top. • Confirm on site: [MEASURE: height of your tallest pebble] and [MEASURE: your resin's maximum single-pour depth]. • Sheet the floor in plastic, level the bench with the spirit level, hold the room at 18–24 °C.
