Object

A useful model showing the application of a simple angle joint, viz. tongueing. In the case of the alternate constructive detail shown, viz. diminished and housed dovetailing, this is more suitable for second and third year work, when a greater degree of proficiency has been attained.

The Process (For Main Elevation And Sectional View)

First year model.

Prepare and plane up to thickness the following material:-

A scale of one-fifth full size could be adopted with advantage in some cases; the cutting sizes would then be as follows:-

1. Plane sides to width, place same together in bench vice, mark finished length on edges, and also the grooves to receive tongue.

2. Place ends in bench vice, set out finished length on edges, also shoulder line.

3. Gauge on thickness of tongue, cut same with dovetail saw. Cut grooves on sides and fit the frame together.

4. Set out shape of end, as per diagram on this page.

5. Bore holes for handles, finish with keyhole saw and files.

Fig. 10.

6. Cut top curve, finish with spokeshave, glue together, and when dry plane up framing all round.

The Decoration of a first or second year model should be restricted to a simple arrangement of gouge cuts or vee tooling. For the third year a strap-work design is shown which is executed by cutting the groundwork away slightly so as to leave the design in relief. Its effect is enhanced if the surface of the strap-work is cut slightly hollow.

Simple decoration could also be introduced round framing, as suggested in the perspective sketch.

Alternate Shapes for the ends are illustrated; these could be supplemented indefinitely. For class work it is recommended that pupils be given definite data for the hand holes, and be allowed to express their own ideas for the outline, subject of course to criticism and guidance. Alternate details are also shown suitable for a moulded bottom.
