Object

To introduce bow sawing and filing exercises. These models are specially valuable for good hand and eye training. Whilst general features are followed, there is ample scope for individual taste on the part of pupils.

Object 37

Fig. 10.

Commencing with the drawing of a plain circle for outline and an inner circle for the recessing, individual effort can be encouraged in developing the outline, chamfering, and ornament of rim.

Material

Sycamore is an excellent wood for this model; limewood may be considered the next best; it is both softer and easier to work than the former. American whitewood is least satisfactory for class work owing to its liability to cast and twist. An average overall size of 12 in. is recommended.

The Process (example No. 1, Fig. 10).-1. Prepare a drawing of the platter, full size, on cartridge paper.

2. Plane up the material on both sides and strike diagonal lines.

3. Transfer the design on to the material.

4. Execute the recessing; this should be done with a flat gouge. (Occasionally it should be tested for correct depth with the templet (see diagram). A router is used to finish the recessing to a uniform depth (see sketch above). Glass-paper can be used to finally smooth up.)

5. Cut outline to shape with bow saw, and finish with file.

6. Execute carving with gouge cuts square to face side; the groundwork is then levelled (see section above), leaving the strapwork or leaves, etc., in relief.

7. Complete the model by spacing and pencilling the chamfer decoration, file this part, and finish with sandpaper.

Notes

The first example, described above, is worked upon a circular geometrical basis, the decoration is centred upon diagonal lines. The second specimen has a hexagonal form, the sides being converted into curves with small intervening detail. The main elements of the strapwork decoration are spaced in between the diagonals. The third example is based upon an octagon, and the leaf decoration is intended to be slightly recessed.

No. 4 is based upon a circular outline, with simple conventional floral ornament at the ends of the diameters.

No. 5 shows an example worked upon a circle and diagonal lines, as does also the last specimen, the decoration in this case being in slight relief from the rim or groundwork.
