the amount of the thickness of the
leather which will cover the table. In some cases the margin at the end
runs the same way of the grain as the top, thus allowing for slight
shrinkage. Cross tongues would of course be used in this case.

Fig. 110 is a sketch showing one-quarter of a barred or tracery cabinet
door. An enlarged section of the astragal mould which is grooved to fit
on the bar which forms the rebate is also shown.

Fig. 111 is a "Combing or corner locking" joint, a method of making boxes
by means of a continuous use of tongues and grooves instead of dovetails.
This type of joint is generally machine made. The amateur, however, who
is not proficient to undertake a dovetailed box frequently uses this
method.

CORNER JOINTS.--Fig. 112 shows both a single loose tongue and a double
solid tongue. Both are methods used to connect circular cornered work,
such as a counter end, to the front framing.

Fig. 113 indicates a tongued and grooved joint suitable for edge or end
jointing, such as fitting matchboarding round a chimney breast, making
small jewel drawers, etc.

Fig. 114 is a tongued and grooved joint with a bead worked on same to
hide the joint, sometimes called a staff-bead. It would be used in
positions such as boarding around an upright iron pillar, etc., the bead
giving a neat finish at each corner.

Fig. 115 is a similar joint, but at an obtuse angle. An example of its
use is in fixing boarding around an octagonal column of brickwork.

Tongued and Grooved Corner Joints.]

Fig. 116 shows a tongued and grooved mitre as used for strengthening the
corners of cabinet work, such as tea caddies, small boxes, plinths, etc.
Two pieces of wood are glued in position and allowed to set prior to
glueing and cramping the joint proper. These pieces are afterwards planed
away, thus leaving a clear surface to the box sides.

Fig. 117 shows the method of working the groove in the above joints. The
pieces are turned back to back, the mitres thus making a right angle. The
guide on the grooving plane thus works against each face of the joint,
and this ensures correct jointing.

Fig. 118 is somewhat similar to Fig. 113, but with a quarter circle mould
to hide the joint.
