With the advent of cold weather, the issue of space heating again arose. What to do when you need to warm up quickly and without hassle garage, warehouse, basement or any other room? One author for these purposes has developed an interesting device that allows you to quickly solve problems. An ordinary blowtorch will be used as the basis for heat generation. Take a closer look at how you can do it yourself assemble such a device and forget about the cold.
Materials and tools for making guns:
- blowtorch (preferably as the author);
- drill with drills;
- grinder;
- metal plates (thickness 2 mm, length 15-20 mm, and width depending on the size of the lid body);
- welding;
- filling freon cylinders (to create a housing);
- folding fan;
- marker, ruler and other little things;
- a piece of iron pipe (the diameter of the lamp ejector).
Gun manufacturing process:
Step one. Disassemble the lamp
First you need to take a blowtorch and take it apart. From her to homemade you only need an ejector, that is, a device that emits a flame. You will also need an adjustment tap. Further, so that a hose can be connected to the ejector, an adapter must be adapted to it. The author makes it from a piece of copper pipe. It is important to understand that during the operation of the lamp, the ejector will heat up to 1200 C, so putting the tube on the glue will not work. A minimum for these purposes you need to use a soldering iron, and it is best to use gas or electric welding.
Step Two Refinement of the ejector
Now you need to work a bit with a drill. The fact is that to start the burner, the diameter of the nozzle hole must be made larger. For these purposes, the nozzle must be drilled with a drill at 1.5 mm. To do this, they twist it and clamp it in a vice. The main thing is to make the hole clearly centered, otherwise the burner will not work properly.
Step Three We make a burner extension
Next, you need to find a piece of iron pipe, in diameter it should be such that it fits the exit of the blowtorch.Next, a grinder is taken and with its help longitudinal slots are made in the pipe, then metal plates are inserted into these niches. The author has four of them. Welding is used to fix the plates. The thickness of the plates should be about 2 mm, the length is about 20 mm, and the width is already curled from the diameter of the lid of the gun body.
Step Four Build and Test Guns
At the final stage, the extension for the burner is welded by welding to the lamp. Next, you can proceed with the assembly of the body of the gas gun.
To fix the fan, the author used a housing from a freon gas cylinder; it was he who was the best suited for the diameter of the structure. As a result, the system will consist of two parts. One will have a fan, and the other a burner with an extension cord and three openings for the release of warm air.
If you want to remove heat to a specific place, then you can weld a piece of pipe to the structure and put a corrugation on it. After making the case, an extension cord is inserted into it and fastened with a clamp.
To kindle the gun it was easier, the author made the fan folding, that is, it is mounted on a hinge. After arson, you need to wait until the lamp starts to burn steadily, after which the fan is put on and turned on.
That’s all, the gas gun is ready, but it has one drawback, carbon dioxide is released during its operation, which can be a health hazard. In this regard, the output of the gun must be inserted into the stove or to drive all this red-hot air through a conventional liquid cooling system, making minor modifications. According to the author, the device turned out to be quite simple and very effective.
