• Make a lath frame inside the cleats frame,
• Make a lath frame outside the cleats frame,
• Put cleats vertically between the two lath frames, as an extension of the central legs, and one on each side of the four angles,
• Cut some planks to lift the initial frames (inside and outside) so that the height of the pool is 30 cm at the front and 40 cm at the back. The two sideboards must be cut diagonally to bind the two sides of the basin,
• Fix the two new frames (inside and outside) on the vertical cleats resting on the first frames. Start with the inner frame,
• Cut the parts of the vertical cleats that protrude.

ATTENTION For the inner frame, the screws must come from the inside and go outwards otherwise there is a risk of bursting the tarpaulin. HINT Add straw, wool, newspaper or cardboard between the two frames to insulate even better.
