Bows, crossbows were once weapons armies. Today they help to have fun and try their accuracy. In this article, we will review a video on manufacturing a powerful block bow.
Let's start by watching the author’s video
What do we need:
- wooden blocks;
- metal corners;
- self-tapping screws;
- screwdriver;
- rollers;
- steel plates;
- loops;
- spray paint;
- two powerful springs;
- strong rope;
- sandpaper.
We take one wooden beam 38 cm long, 2 cm thick and 4 cm wide and two shorter blocks - 16 cm long. We fix two small bars on a long one using metal corners and screws.
We strengthen the handle with additional long-lasting screws.
As a result, we should get a similar design.
We process the resulting handle with sandpaper.
Next, take two 46 cm of the bar, which we will use to make shoulders for our bow. Not far from the edge we drill a hole and cut out a recess for pulleys or rollers.
According to the author, rollers for making onions can be purchased at the car market. The author, for example, uses rollers that are used to raise windows in cars. Two such videos can be purchased for a dollar.
Next, we take steel plates and bend them as shown in the figure below.
Using these plates, we fix the rollers to the bars with screws.
Next, we need to fix the shoulders on the handle and we will do this with the help of door hinges, which we also fix with self-tapping screws.
Before fastening our structure, you can paint it with ordinary spray paint.
Next, take two corners and fix them on the free edges of the shoulders.
At this stage, we need a couple of powerful springs, which can also be purchased at the car market again for a dollar. We attach one edge of the spring to the corner, and the second to the handle. To do this, make a notch on the handle. Also on the handle you need to make a through hole and insert some convenient bolt into it, on which the second end of the spring will be fixed.
Block onion is almost ready. We take a strong rope and fix it on the shoulder of the bow, threading it into the hole.
Next, thread through the opposite roller from the inside and through another roller from the outside. In the same way we fasten the edge of the rope to the other shoulder.
The boom stand can be made from a spray with a moving plastic part. We need exactly the moving part on which the arrow will be held. When fired, the part will fall down and will not prevent the arrow from flying out of the bow.
According to the author, for shooting from such a bow it is necessary to release metal parts so as not to damage the fingers when stretched.
