The plinth is made up of two stands: an outer one, of which the legs are an integral part, and an inner one that adds strength, holds the carcass clear of the outer stand and adds the bin (12mm) gap which gives visual interest to the design.

1 Cut the eight pieces of timber that are required to make the four legs to length and width, square them up with a plane and join the corners of each pair of pieces that make one leg, using dowels (see page 25). Glue and then clamp them together, and while waiting for them to dry, cut the two long and two short rails to size.

2 Dowel and glue the rails to the legs, using sash cramps to hold them in position. Before the glue is set, check the diagonals of the stand to ensure that it is square.

If the diagonals are ngt equal, loosen the sash cramps slightly, lay another sash cramp across the long diagonal and tighten it until the diagonals of the frame are the same length. Leaving this clamp in position, re-tighten the other clamps. When set clean off all the glue and plane the outside of the frame flat (see Fig 17.4).

3 Cut the rails for the inner stand to size. Join the corners with bare-faced housing joints, and fit the cross rail in the centre of the long rails with a simple housing joint (see page 20). Before gluing the joints together, drill and countersink a series of screw holes in the rails both to join the inner stand to the outer stand and to join the inner stand to the carcass after it has been made.

4 Assemble the inner stand dry and fit it into the outer stand to check for accuracy of the fit. Adjust if required. Glue and screw the inner stand to the outer stand, with ^in (12mm) protruding from the top of the outer stand (see Fig 17.5).
