How to make a reusable aerosol from a regular one
We are used to throwing away empty aerosol cans without bothering to reuse them. However, today's homemade project refutes these stereotypes and shows how you can give a second life to the most ordinary empty paint can. So, let's go!
On the collar of the cylinder, usually free of paint and varnish coatings, we make a marking and core it with an awl under the hole. The nipple must first be disassembled by removing the spool from it so as not to melt during soldering.
Using a screwdriver, drill a hole with a diameter of 3-4 mm at a slight angle.
Degrease the surface of the nipple and the soldering zone on the cylinder. A special degreaser, gasoline or solvent 646 is suitable for this. Wipe the surface dry with a clean rag.
Apply flux to the back of the nipple and around the hole on the cylinder.
An ordinary bamboo skewer will help you align the nipple at the soldering site.We put a nipple on it and thread it through the hole, aligning it exactly in the center.
We heat the base of the nipple with a gas burner and solder it with solder. But before this operation, be sure to make sure that there are no flammable vapors from the solvent left in the cylinder. Otherwise, the open flame may rupture the cylinder, which will definitely cause injury to you. To avoid this, fill the bottle full of water and pour it out. And just before soldering, fill the container 80% to reduce the internal volume. Then draining the water through the hole under the nipple is not difficult.
You can cool the soldering area with plain water. We assemble the nipple back by screwing the spool into the sleeve.
A securely soldered nipple will be able to withstand sufficient pressure for reusable use of the cylinder. You can immediately check it by pumping air with a regular bicycle pump.
Such a reusable aerosol can can be used, for example, to brush away small debris from the working surface of parts.
You can refill homemade lubricant and save hundreds of rubles on the purchase of WD-40. You can pour in paint and paint. You can pour eau de toilette and use the bottle as a freshener. There are a lot of applications, go for it.
We will need:
- Aerosol can of paint (or any other) – 1 piece;
- Bicycle nipple (car nipple can also be used) – 1 piece;
- Knife, awl, screwdriver with 3-4 mm drill;
- Gas torch, solder, flux (preferably soldering acid).
