Attaching the Trestles.--Stand the trestles on their heads and lay the
back and front up to them, using the guide marks just drawn. A nail driven
part way in through one of the screw holes, and a batten tacked diagonally
on the DD lines, will hold a leg in position while the screws are inserted.
(Make sure that the tops of the legs and the top edges of B and G are in
the same plane.)
Affixing the Braces.--The braces DD, of 3 by 1 inch stuff, can now be
marked off and cut exactly down the middle to the limits of the overlap.
Screw on the braces.
The bearer F is next cut out. Its length should be such as to maintain the
exact parallelism of B with G, and the ends be as square as you can cut
them. Fix it in position by two 2-inch screws at each end.
The bench is now ready for covering. Begin with the front board, A1. Bore
countersunk holes for 3-inch screws over the centre of the legs and half an
inch from the front edge, 1 foot apart. Arrange Al with its front edge
perfectly flush with the face of B, and tack it in place by nails driven
through a couple of screw holes, and insert all the screws.
