For Incised letters, a “V” section (1, fig. [217]) of about 60° is best for regular use; deeper rather than shallower. The letters may with advantage be cut a little deeper towards the Serifs (see fig. [218]).
Although the simple “V” section is the most useful, other sections may be used for large letters (i.e. letters more than 6 inches high), or letters in a very fine material (2 & 3, fig. [217]).
If the lettering is to be gilded, and the stone will permit of it, Section 4 (fig. [217]) is a good one to use. Only the curved part is to be Gilded, and not the small bevelled sides.
For Raised letters, the best and most useful section is No. 5; the slightly bevelled sides tell as part of the letter. Experience, and the weathering conditions, will suggest the amount of Relief to be given. For letters 112 inch high, out of doors, 316 inch of relief is ample, and if there be good light 18 inch is enough. Excessive relief looks clumsy.
Sections Nos. 6 and 7 are suitable only for large letters; and elaborate sections should as a rule be used only for letters standing alone.
WORKING IN SITU
If possible the carver should work in situ. When that is impracticable,[129] he should consider most carefully where his Inscription is to go. [p406]
In an Inscription which is much above the eye level, the letters may be narrower in proportion to their height, and the horizontal strokes extra thick to allow for foreshortening. (See also pp. [351], [270].)
