The frame for the bathroom or lavatory glass here illustrated may be of birch or some hard wood. The moulding can be worked in two lengths of 6 ft., 1 1/4 in. by 3/4 in., which will allow for jointing, cutting, etc. A 1/4-in. bead is run through the centre on the face side; this can be done by a beading plane with adjustable fence, or by a hand scratch tool. A rebate is worked on one edge 1/2 in. wide by 3/4 in. deep. The cross rails are secured to the uprights by mortise-and-tenon joints. The top spindle rail is not rebated, but is left with a square edge all round. The shelf is 1/2 in. thick by 4 in. wide, screwed to the under side of bottom cross-piece. The tail-piece is made from 1/2-in. stuff, sawn to shape with a bow or compass saw and secured to the frame with a couple of nails at each side passing through the uprights. The spindles are 1/2 in. long exclusive of dowels, and the tips are 1 7/8 in. long and 1 3/8 in. in diameter, the dowels fitting into holes bored in the ends of the uprights and spindle rails. The mirror is 1ft. 2 1/2 in. by 1 ft. 4 1/2 in., a stock size with some of the large dealers. The bevelled edge improves the appearance. The frame can be stained and polished, or left in the natural wood.
A method of hanging is not shown, as ways will suggest themselves according to the position the glass has to occupy.
