Though wood is not generally used for door knockers, some excellent specimens have been executed in this material, notably those at Gwydir Castle, Wales. In one a conventional rendering of a lion's head is the outstanding feature, while another example shows a pleasing application of chiselled work. An iron button is fixed below the actual knocker, which strikes against an iron plate cut into the door.
Oak is suitable material, left in natural condition with high parts coloured. Lime wood is an easier material to use, but should be painted. Necessary boldness is given to the lettering, etc., by painting with a contrasting colour.
The Name Plate.-The lettering is best executed by drawing upon cartridge paper. Good examples in various styles are given in Lewis F. Day'sAlphabets Old and New". Geometrical constructions are recommended. When a satisfactory design has been prepared, it can be transferred to the planed surface of the wood by the insertion of carbon paper between the design and the wood. A hard pencil is used to trace the outline, which leaves corresponding marks on the groundwork.
The letter R illustrated is cut round (as shown in section in Fig. 6) with a sharp gouge; the outside part of the gouge cuts is then pared down, producing the bottom section shown, the letter standing up in relief.
The letter Q illustrated should be gouged 1/12, in. deep, square with groundwork, then gouged down as shown in section, leaving a V shape. In P a similar preliminary process is effected, then the back parts are removed with a"grounding-outtool.
The letter B is the simplest to execute. Vee cuts are made, the sharp edge of the outside part being removed with a chisel.
For The Knocker the following procedure is satisfactory:-
1. Plane up material to thickness of 3/4 in.
2. Draw centre line on wood, freehand strapwork design on one side, com-
3. Outline the inside part of the design with chisels and gouges and cut down back parts as shown in the section.
4. Cut outside of shape with bow-saw and finish with file.
5. Fix hinge, button, and striking plate.
