By drawing several ellipses of varying sizes upon sheets of tin or zinc, a series of templates of utmost practical value may be formed and used as was done in securing the curves of force in Figures 74 and 75.
It is advisable to form several templates for the volute out of bent wrought iron, of different sizes, and to practice drawing the curve many times to accustom the hand and the eye to its changes of direction.
Both templatesand arch forms were constructed of wood.
The upright bars in the walls were held together and at the proper distance apart by means of templates consisting of wooden strips in which holes were bored at suitable intervals to receive the bars.
The templates were maintained in a horizontal position and were moved upward as the concrete advanced in height.
The desired radius of curvature is easily attained by cutting out templates from sheet zinc and using them to gauge the turning.
Another very handy way of making templates of great accuracy is to use a beam compass (constructed from a light wooden bar) with a glazier's diamond instead of a pencil.
To draw curves that are not formed of arcs or parts of circles, templates called curves are provided, examples of these forms being given in Figure 6.
In shops where there are many of the same pieces forged, the blacksmith is furnished with sheet-iron templates that he can lay directly upon the forging and test its dimensions at once, which is an excellent plan in large work.
Such templates are, of course, made from the drawings, and it becomes a question as to whether their dimensions should be the forged or the finished ones.
If the inspection should take place at the foundry, the templates used in chipping might be verified and used for inspection.
The templatesare employed to mark out on the board which should first be planed to the required thickness.
Gauges of these two kinds, however, are generally used more in the sense of being templates rather than measuring tools, since they determine whether a bore is of the required size rather than determine what that size is.
Both these templates are set to the pitch circles and to coincide with the marks made on the wheel teeth to denote the thickness, and with a hardened steel point a line is traced on the tooth showing the correct curve for the same.
When the teeth are to be cast upon the wheels the pattern-maker makes templates of the tooth curves (by some one of the methods to be hereafter described), and carefully cuts the teeth to shape.
An experienced hand will find no difficulty in producing true templates by this method, but to avoid all possibility of the segments slipping on coarse pitches, and with large segments, the segments may be connected, as shown in Fig.
But when we come to apply these templates to the work, we shall find that A is the better of the two, because we can apply the square S, Fig.
The Pratt and Whitney Company have, however, produced a machine that will produce templates of far greater accuracy than can be made by hand work.
But the production of these templates is a tedious and costly operation, and one which is very liable to error unless much experience has been had.
The mortises are first dressed out to a uniform size and taper, using two templates to test them with, one of which is for the breadth and the other for the width of the mortise.

It will be an easy matter to make these templates by following Fig.
The cardboard templates must be cut, one for each half-section, as shown in the body plan, Fig.
These templates serve to show the proper outside shape of the hull.
The block for the hull must be cut away until each one of these templates fits properly into place.
The hull is made according to the built-up principle, and the constructor will have to cut his templates before attempting the shaping of the hull.
Templates of the cross-sections should now be made from thick white paper.
The templates should be cut from heavy cardboard so they will hold their shapes.
When the builder starts to use the spoke-shave he should also start to use his templates or forms, applying them sectionally to determine how much more wood he will have to remove to bring the hull to shape.
Try yourtemplates now and again as you work, and do not try to finish one spot, but keep the whole at an even stage, and you will see the hull gradually grow into shape.
If one can imagine the visible half of the vase form as it appears in making the mold, with the templates and ends cemented into one piece, one has a conception of one half of a case.
As soon as the plaster has become warm the whole may be turned over and the templates and end plates removed.
Vase, foot piece, templates and end pieces are all to be sized thoroughly in the manner described.
The outside diameter of the mold is now to be determined and the templates cut to this dimension so that the two together, with the vase between them, constitute a longitudinal section of the mold.
Some soft clay is now built up on each side of the vase and the templates are pressed down upon it, one on each side until the upper face of each corresponds with the scratched line.
The pair of templates must include, in their outline, both the spare and the foot piece but should not extend beyond either of these.
