What weapons are currently invented! Despite all the innovations, even in the field of hunting weapons, interest in the bow still does not fade. And this is understandable - you can often hear about the special sensation of arrows and bowstrings.
One way or another, modern developments have affected hunting bows. One of the latest know-how in this area is block bow. With your own hands, you can feel at the first shot its advantage over the usual option.
It got its name due to its use in the design of a block system. It can be two blocks located at the extreme points of the bow shoulders, or one on the lower shoulder. Moreover, the second option is preferable because of a simpler setup.
What is the advantage?
The block system - an eccentric on the lower shoulder plus a roller on the upper - due to the tension of the cable, can sharply increase the tension of the bowstring, and then sharply reset. In this case, the boom speed can reach 100 m / s.
Many may be interested in making a blocky bow with their own hands. In addition to the block system, the bow is usually equipped with a stabilizer and scope. Perform a full scope of improvised materials will be at least difficult.
Do it yourself is a feasible task for people with experience in this field. The handle can be made of either high-strength plywood or wood. If you chose the second option, then the task may be complicated due to the search for a bar of suitable sizes. After processing, the product must be coated with stain and varnish in several layers. I must say that this is the easiest part of the work.
Making a block bow with your own hands, you can face many problems. What are they? Making a professional hunting bow, difficulties are caused by the manufacture of shoulders. In this case, it is unlikely to apply multilayer plywood, it is better to use fiberglass. From it to make a multi-layer construction of the shoulders. Here, often there are problems with internal deformations with excessive stress.
The next step is a block system. The blocks themselves can be made of various materials. The easiest way is to order the necessary steel block on a lathe. The best option is eccentric blocks.
The stabilizer is made in the form of a rod with a moving weight. The load is fixed with a screw. You can make either a long but lighter stabilizer, or a short and heavy one.
Other parts, such as the bar for retracting the bowstring and the arm for the boom, are made of metal (aluminum or steel). Fastening is carried out using screws. The shelf for removal can be made of wire. She must be provided with a stroke to adjust the length.
For a bowstring, you can use Kevlar thread or “braid”.
It should be noted that making a block bow with your own hands is quite realistic, but this is rather out of interest in the manufacturing process itself. It’s unlikely that we can make such a rather high-tech weapon on our own. So if the goal is to obtain a powerful block onion, then it is better to purchase it in a specialized store.
