What weapons are nottime! Despite all the innovations, even in the sphere of hunting weapons, there is still no interest in the onions. And it is quite understandable - you can often hear about the special feeling of the arrow and string.
He received his name thanks to the application inconstruction of the block system. It can be two blocks located at the extreme points of the shoulders of the bow, or one - on the lower shoulder. And the second option is preferable because of the simpler setting.
What is the advantage?
Block system - eccentric on the lower shoulder plusthe roller on the top - due to the tension of the cable allows you to dramatically increase the tension of the bowstring, and then sharply discard. In this case, the boom speed can reach 100 m / s.
Many may be interested in making a block onionown hands. In addition to the block system, the bow is usually equipped with a stabilizer and a sight. To complete a full scope from improvised materials will be at least inconvenient.
Make a small onion with your own hands - feasibletask 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, the task can be complicated by searching for a suitable size bar. After treatment, the product must be covered with stain and varnish in several layers. I must say that this is the simplest part of the work.
Doing a blockbow on your own, you canencounter many problems. What are they? Making professional hunting onions, it is difficult to make shoulders. In this case, it is unlikely to use multi-ply plywood, it is better to use fiberglass. From it, make a multi-layered construction of the shoulders. There are often problems with internal deformations at excess voltage.
The next step is the block system. The blocks themselves can be made of different materials. The easiest way to order the necessary steel block on a lathe. The best option is the eccentric blocks.
The stabilizer is made in the form of a bar with a moving weight. The cargo is fixed with a screw. You can make a long, but easier stabilizer, or short and heavy.
Other parts, such as the pull rodbow strings and bracket are made of metal (aluminum or steel). Fastening is carried out by means of screws. The retractable shelf can be made of wire. She must have a stroke to adjust the length.
For the bowstring, you can use a kevlar thread or a "braid".
It should be noted that to make a bow onionshands is quite real, but it's more of an interest in the very process of making. Own forces are unlikely to be able to produce such a pretty high-tech weapon. So if the goal is to get a powerful block onion, then it's better to buy it in a specialized store.
