** Homemade Workbench [442]
By C. E. McKINNEY, Jr.

The first appliance necessary for the boy's workshop is a
workbench. The average boy that desires to construct his own
apparatus as much as possible can make the bench as described
herein. Four pieces of 2 by 4-in. pine are cut 23 in. long for the
legs, and a tenon made on each end of them, 1/2 in. thick, 3-1/2
in. wide and 1-1/2 in. long, as shown

[Illustration: Details of Construction of Homemade Workbench]

at A and B, Fig. 1. The crosspieces at the top and bottom of the
legs are made from the same material and cut 20 in. long. A
mortise is made 1-1/4 in. from each end of these pieces and in the
narrow edge of them, as shown at C and D, Fig. 1. The corners are
then cut sloping from the edge of the leg out and to the middle of
the piece, as shown. When each pair of legs are fitted to a pair
of crosspieces they will form the two supports for the bench.
These supports are held together and braced with two braces or
connecting pieces of 2 by 4-in. pine, 24 in. long. The joints are
made between the ends of these pieces and the legs by boring a
hole through each leg and into the center of each end of the
braces to a depth of 4 in., as shown at J, Fig. 2. On the back
side of the braces bore holes, intersecting the other holes, for a
place to insert the nut of a bolt, as shown at HH. Four 3/8 by
6-in, bolts are placed in the holes bored, and the joints are
drawn together as shown at J. The ends of the two braces must be
sawed off perfectly square to make the supports stand up straight.

In making this part of the bench be sure to have the joints fit
closely and to draw the bolts up tight on the stretchers. There is
nothing quite so annoying as to have the bench support sway while
work is being done on its top. It would be well to add a cross
brace on the back side to prevent any rocking while planing
boards, if the bench is to be used for large work.

The main top board M, Fig. 2, may be either made from one piece of
2 by 12-in. plank, 3-1/2 ft. long, or made up of 14 strips of
maple, 7/8 in. thick by 2 in. wide and 3-1/2 ft. long, set on
edge, each strip glued and screwed to its neighbor. When building
up a top like this be careful to put the strips together with the
grain running in the same direction so the top may be planed
smooth. The back board N is the same length as th
