Object And Uses

Used for the strengthening of chests and also form an ornamental feature. Introducing development of surfaces.

The Joints

When the corner plates are bent up they form what is known as aclose joint".

The Process

As a number of plates would be necessary to furnish a chest a template would be required. This could be made from some thin sheet metal, and should be arranged so that the bending lines could be scribed through.

1. These should be made from 16 or 14 I.S.W.G. metal. Lay the templet on and hold with a hand vice and mark round it with a scriber.

2. Cut out to shape, either chisel or saw pierce.

3. Punch or drill holes for screws and punch or engrave ornament.

4. Anneal so that material is soft, and dress up.

5. Bend up to shape and test with a set square.

6. Polish and lacquer if necessary.

The Decoration is either by punched holes, raised ornaments of simple form, piercing, and engraved lines which can be done with a chisel, a graver, or a tracer.

(1) Upsetting.

(2) Bending.

(3) Swaging.

(4) Chopping out.

Special Features

A very simple model which gives good practice in simple setting out and development of surfaces. If only one was being made, a templet would not be necessary, but the whole thing could be set right out on to the metal. This model admits of many variations.
