And so you must work and test your bow, and shoot it, and draw it up before a full length mirror and observe its outline, and get your friends to draw it up and pass judgment on it. In fact, while the actual work of making a bow takes about eight hours, it requires months to get one adjusted so that it is good. A bow, like a violin, is a work of art. The best in it can only be brought out by infinite care. Like a violin, it is all curved contours, there is not a straight line in it. Many of my bows have been built over completely three or four times. Old Horrible first pulled eighty-five pounds. It was reduced, shortened, whip ended, and worked over again and again so to tune the wood that all parts acted in harmony. Every good bow is a work of love.

Your bow is now ready to shoot, but let us weigh it first. Brace it and put it horizontally in the vise with the string facing you. Take a spring scale registering at least eighty pounds and catch the hook under the string. Draw it until the yardstick registers twenty-eight inches from the string to the back of the bow. Now read the scale; that is its weight.

As a matter of convenience I have devised a stick that facilitates the weighing. I take a dowel and attach to one end by glue and binding a bent piece of iron so fashioned that the extremity serves as a hook to draw the string and the bent portion permits the attachment of the scale. The dowel is marked off in inches so that one can test different lengths of draw. With the bow in the bench vise, this measure hooked on the string and resting on the bow at the arrow plate, the scale is hooked in place, the dowel drawn down to the standard length and the registered weight read off on the scale.

If you still find that your bow is too strong for you, it must be further reduced. Begin all over again with the spoke shave and the file, trying to correct any inequalities that may have existed before and reducing it to what ultimately will be sixty-five pounds. Put on the string and weigh it again and again until you get the weight you want. If you have reduced it too much, cut it down two or four inches; it will be stronger and shoot better.

All yew bows tend to lose in strength after much use, and your new one should pull five pounds more than the required weight. If a bow is put away in a dry, warm place for several years it nearly always increases in strength. In our experience one in constant use lasts from three to five years. The longer the bow, the longer its life. Some, of course, break or come to grief after a short period, others live to honorable old age. Yew bows are in existence today that were made many thousands of years ago, but, of course, they would break if shot. Many bows over one hundred years old are still in use occasionally. I have estimated that the average life of a good bow should exceed one hundred thousand shots, after which time it begins to fret and show other signs of weakness.

Keeping in mind the idea of making your weapon as beautiful, as symmetrical and resilient as possible, free from dead or overstrained areas, work it down with utmost solicitude until it approaches your ideal. Smooth it with sandpaper; finish it with steelwool.

Now comes the process of putting on the nocks. A bow shoots well without them, but is safer with them.

From time immemorial, horn tips have been put on the ends of the limbs to hold the string. We have used rawhide, hardwood, aluminum, bone, elk horn, deer horn, buffalo horn, paper fiber or composition, and cow's horn. The last seems best of all. From your butcher secure a number of horns. With a saw cut off three or four inches of the tip. Place one in a vise and drill a conical hole in it an inch and a quarter deep and half an inch wide. This can be done by using a half-inch drill which has been ground on a carborundum stone to a conical point the proper length. In this hole set a stout piece of wood with glue. This permits you to hold the horn in the vise while you work it.

After the glue has set, take a coarse file and shape the horn nock to the classical shape, which is hard to describe but easy to illustrate. It must have diagonal grooves to hold the string. The nock for the upper limb has also a hole at its extremity to receive the buckskin thong which keeps the upper loop of the string from slipping too far down the bow when unbraced.

The nocks for hunting bows should be short and stout, not over one and a half inches long, for they get a lot of hard usage in their travels. They should also be broader and thicker than those used on target bows.
