The middle
board, A2, is laid up against it, and the back board, A3 (bored for screws
like the front board), against that. Screw down A3.
You must now measure carefully to establish lines over the centres of CC
and F. Attach each board to each of these by a couple of screws. All screws
in the top of the bench are countersunk 1/8 inch below the surface. Screw
the ledge E, of 4 by 5/8 inch wood, on to the back of G, with 2-1/2 inches
projecting. This will prevent tools, etc., slipping off the bench.

The Vice.--This important accessory consists of an 8 by 2 by 15 inch
piece, V, a 2-inch diameter wooden bench screw and threaded block, and a
guide, F. (Note.--A 1-1/8-inch diameter wrought iron screw is very
preferable to the wooden, but its cost is about 4s. more.) V should be
tacked to B while the 2-inch hole for the bench screw is bored through both
with a centre bit, at a point 8 inches from the guide end on the centre
line of V. This hole must be made quite squarely to enable the screw to
work freely. If a 2-inch bit is not available, mark out a 2-inch ring and
bore a number of small holes, which can afterwards be joined by a pad-saw;
and finish, the hole thus formed with a half-round rasp.
