Subject

The hinges which are illustrated in Fig. 4 are Elizabethan in character, but the large one is distinctly Dutch.

Fig. 4.-Examples of Jacobean hinges.

Fig. 5. - Strap hinges and a method for making the knuckle.

Those illustrated in Fig. 5 are modern, and any of these could be modified to suit existing conditions.

The Processes

1. Make a full-size drawing of the hinge selected.

2. Make a tracing of the ornamental side, and transfer or gum on to thin sheet metal.

3. Cut the templet out, allowing it to butt up against the outside of knuckle.

4. Cut out the metal roughly to shape for the hinge and the flap, allowing for the knuckle.

5. Roll up the metal for the knuckles using the steel mandril, as illustrated in Fig. 5, Nos. 1, 2, 3, 4, 5.

6. Set out the knuckles for cutting, and notice should be taken that in a three-knuckle hinge the centre ones equal the other two, in a five-jointed one the two equal the three.

7. Cut the knuckles, file and fit them together neatly.

8. Lay the templet on the hinge and mark it out.

9. Raise or cut it out to the shape, and trim it up with files.

10. Drill the fixing holes, and file off the burrs.

11. Cut and fit the pin for the knuckle; if knobs are going to be used, the pin should be screwed, and the knobs drilled, tapped, and turned. For shapes of turning tools for brass set see Ch. xvi, f. 22, and for method of holding them see Ch. VII, f. 7.

12. The parts should now be polished, coloured, and lacquered.

13. Put it together, taking care not to scratch it; re-lacquer if necessary. See that the knobs do not bear on to the knuckle, they must screw down tight on to the pin.

The Decoration

This is obtained by embossing, piercing, shaping of the outline and chamfering, while the iron hinges should be hammered all over the face and chamfers with a polished face hammer, which gives them a kind of texture, like those shown in Ch. XII, f. 9, but it must be done carefully and with judgment or a pitted appearance will be the result.

Note

These models introduce knuckling and consequently careful fitting. As hinges are made in many different forms, to suit varied conditions, these could be modified, so giving an opportunity for adapting, or designing to suit the particular purpose for which they are required.
