The simplest method of getting the marks right is to cut a template out of thin card and apply it to the two ends in turn, using the base of each as the adjusting line.
The template is applied to the end side of the leg and moved up till its sloping edge occupies a position in which a perpendicular dropped on to it from C is 1/2 inch long.
The bevel is marked on the other side of the leg, the, angle of the template being at E1 (Fig.
Tubes H must be bent to a template to get them all of the same shape and length, and all the tubes be prepared before any are put in place.
The work of marking the ends of the notches will be quickened, and rendered more accurate, if a template (Fig.

The pattern should then be carefully cut out of the thin board and used as a template for marking out on the stock the form of the curved rails.
A template or gauge will be needed to test the work as it progresses from the first rough stages to the finish.
This is made of card-board by cutting out an exact copy of the profile, leaving at the bottom sufficient width to insure rigidity when the template is held upright on the table or bat.
A pair of barrels was now taken and a template fitted accurately to the side of the right-hand one.
As the template fitted the barrel when the latter was not subject to internal pressure, upon such pressure being applied any alterations that might ensue in the length or contour of the barrel could be duly noted.
A single barrel was now taken, to which a template was fitted, in order to record its exact length.
Then place one of these with each of the unbored legs and bore these, using the first pair as template for boring the second.
Place this template on the wood, and with a sharp pencil, held vertically, draw lines around the edge of the template.

After a little practice it will be found possible to bring the glass exactly up to the required curvature as tested by template or spherometer.
A convex and concave glass surface having been thus roughly prepared, they must be mounted in turn in the lathe, and brought to the proper curvature by grinding with the tools formerly employed and tested by the template or spherometer.
If great accuracy is wanted, make a wooden template and suspend it by a screw from the side of the table, so that the vertex of the gauge for the interior angle projects downwards, then finish by bending the tube round it.
The surface of the lens can be roughly shaped by turning to a template or pattern made by cutting a circular arc (of the same radius as the required surface) out of a bit of sheet zinc.
Figure 59 represents such a template as the masons would have used in building Cheops, both for dressing and setting the stones.
A tin or pasteboard template should be prepared the size of the ring section--a half circle is best, and it is easiest made by drilling a hole in the tin and cutting it in two.
Illustration: A Template Having Slots Cut for Drawing Special Vertical and Horizontal Lines on Pages (Fig.
The face of the template forms a guide for a wide chisel, and enables the worker to gradually pare away the moulding to the correct angle.
A curved line will cut all the intersections, and a template made of cardboard, sheet zinc, or veneer, should be made to this shape.
This template is placed on the rail, as shown, and held in position by placing both the rail and the template in the vice.
Both pieces of the timber are now secured to the bench with a handscrew or cramp; the template A will form a guide for the chisel and rebate plane and allow a sharp edge or arris to be worked on the mitre.
The template is put on the ends of the straight pole, and the dowel centres are pricked into the wood.
This template is generally of hardwood, such as beech or walnut.
Many workers who are constantly on dovetail work make a zinc template to the exact angle and keep it specially for the purpose (Fig.
The method of obtaining the correct angles of such a template has already been given on p.
A small wooden template is made out of beech or other hardwood, having its ends cut at 45 degrees.
In other words, the first piece cut out was used as a templatefor laying out the second.
To make the tray perfect, an inside template can be used.
To secure this curve, saw out a template in white pine about fifteen inches long and 1-1/2 inches wide, at one end, as shown in detail.
A templateis a form cut out of thin wood or metal; in this case 1/8-inch wood should be used.
From this template lay out six pieces of scrap, 2 x 4, and saw them all out the same size and shape.
This templatemethod is used in forming boat models.
Probably the best way of securing a uniform appearance and the easiest, after one good result, is to cut a metal template with a spike at the central point or middle of where the string is to rest.
This of course must be according to measurement or template kept for the purpose if graftings are likely to be wanted in the future.
The Yorktown mugs were hand thrown, but a template was used to shape the ornamental cordoning.
It was first assumed that a single template had served to fashion both the cordons at the base and the groove below the lip.
But in using this template Mr. Maloney discovered that it was impossible to shape the whole exterior of the vessel in one movement without the tools "chattering" against the wall.
After the shaft hole and the holes A are drilled in the disk, it can be used as template for drilling the side plates C.
After the template is marked out, drill the four rivet holes, clamp the template, or pattern, to the sheet iron and mark carefully with a scriber.
It is necessary to layout a templateof the frame as shown, making it 1/16 in.
A corresponding female template being shown at D to be used in planing the table [V]'s.
A template must be made of one of the two forms shown in Fig.
This template must be made slightly larger in every direction than the respective divisions, to allow for the stuff that will be turned off in truing the pattern in the lathe and in jointing the segments to one another during the building.
If we desire to make the templatesuch as at A, we cut out the shaded portion; or for the template at B, the shaded portion.
Assuming, therefore, that the template A is the one to be made, we proceed to test its accuracy, bearing in mind that for this purpose the same method is to be employed whatever shape the template may be.
Now if T T be a 1-pitch template as above mentioned, it is clear that N will correctly shape a cutting edge of a gear cutter for a 1-pitch wheel.
A zinc template for the flank curve is made after the same manner, using the rolling segment in conjunction with the segment B in Fig.
Having completed one half of the pattern, place the two halves together, and trace off the half that is uncut, using again the card template for drawing the lines on the curved surface.
Another form of template much used is shown in Fig.
The curves for the template must be very carefully filed to the lines produced by the rolling segments, because any error in the template is copied on every tooth marked from it.
It will bring this luminosity more home if, in a similar manner to that described above, we make a template of this curve (Fig.
The spectrum must be made narrow, as the template is only theoretically correct for a spectrum of the width of a line, as can be readily seen.
Then turn the template over on the other side and pencil round the edge again.
Lay the template on one half of the piece of wood and pencil round the edge.
To mark off the deck make a cardboard template the shape and size of one half, taken from the middle line, a a.
In constructing the sewer proper the invert was first concreted to template to the height shown in Fig.

How is the required shape of the template or former for winding the coils determined?
The machinery is held firmly in place on the foundation by anchor bolts built into it; the proper position for the bolts are determined by a wooden template suspended above the foundation as shown.
If it is required to draw the coils curved instead of straight across, a template must be made, the curve being obtained as already described for threads.
A tooth thus marked is shown at x, and from its curves between b and c, a templatemay be made for the large diameter or outer end of the pinion teeth.
The thread is first marked on both sides of the bolt, as explained, and instead of drawing, straight across the bolt, lines to represent the tops and bottoms of the thread, a template to draw the curves by is required.
