Do-it-yourself sealed container for kindling

Keychain containers are usually very small in size to make them easier to carry with your keys. Such capsules are mainly intended for transporting tablets. For people who need to take medication on a regular basis. But this interesting little thing can be purchased not only for pills and tablets. There are a huge number of such containers, of a wide variety of types, sizes and purposes, which can be adapted for a variety of purposes.

They are especially good for hikers, fishermen and other outdoor enthusiasts. You can hold in them, without the risk of loss or getting wet, such things as matches (both simple and hunting), kindling for flint, thread with needles, flash drives, micro CD cards... whatever! There are even metal sealed cigarette flasks for that matter! One thing is bad; I have never seen them on open sale. At least here where I live. Only in online stores. But even here there is a risk that the goods will not reach the recipient - out of eleven different containers I ordered, only six arrived.

Making such a container yourself will not be difficult. I have already made such threaded containers before, only very miniature ones. Tiny.

And making a container with a larger thread on the thread is quite easy. If someone doesn’t want to order online (for example, they don’t want to wait for a long delivery), but need such a thing, this master class can be a good help. Once, in one of the master classes, I already described how to assemble a metal shell-flask for flint. Today, we will talk about its addition – a container for kindling.

Will need

A pair of brass shells (of any caliber you like).
A thin brass tube (from an antenna, for example).
Brass or copper threads (external and internal), suitable for the diameter of the sleeve.
A rubber sealing ring that fits onto the external thread.

Tools and consumables for work:

A bur machine or engraver with cutting, grinding and felt discs, as well as a 3 mm drill and a steel brush.
File or needle file.
Sandpaper.
Clamp.
Scissors.
Thin, flexible wire.
Soldering iron, tin and flux.
Paste GOI.

Making an airtight container

The first step is to determine the size of the container. We selected its width when choosing the sleeve we liked. If you need a longer container, then you can solder the hole for the primer at the sleeve with tin, thereby obtaining not only the maximum length, but also the bottom of the container. But this is too much for me, so I sawed the sleeve in half. I left the part with the bottom for the top of the tent pegs, and from the remaining tube I will make a container. I also had another piece from the top of the sleeve, from which I will make the bottom and lid. So, first you need to solder the bottom.The work ahead will not be long, easy, and quite interesting. We cut a short piece of brass tube lengthwise and align it to form a plate.

We cut this plate into squares that will cover both ends of the future container in size.

We coat one of the squares and the end of the brass tube with flux.

We press them together with a clamp or tie them together with wire. Throw a piece of tin inside and heat it with a soldering iron until the tin melts and spreads around the entire perimeter of the bottom.

We wait until it cools down. It's cooled down. We cut off the protruding corners with scissors and finish the edges with a file or engraver.

Next you should solder the internal threads. The principle is almost the same; We coat the edges to be joined with flux, heat it with a soldering iron and tin it with tin.

Now we apply the thread to the body, fix it with wire, and heat it with a soldering iron until the tin spreads.

You can put the container (or rather, only its blank for now) aside and work on the lid. To do this, take a second square of brass, coat it with flux, attach an external thread to it, put tin inside, clamp it, and heat it with a soldering iron.

Next, after it has cooled, screw the lid onto the container blank, and also cut off the protruding edges and corners with scissors. We smooth the edges with a file. All that remains is to solder the ring holder to the lid. I used a brass antenna tube for this. We drill a through hole in the tube, about three millimeters below the edge, and saw off the tip with a hole, about a centimeter long.

And in the same way as described above, solder the tube to the lid. Also, use a file to remove the tin that protrudes after soldering.Now we carefully and thoroughly go over the entire surface of the container body with sandpaper (or a metal brush) to remove carbon deposits and dirt remaining after soldering.

Sand with felt and goi paste. We put the rubber seal on the thread of the lid (unfortunately, I tore mine, so the sample shows it without it). There you go. Fill the container with kindling. The best kindling, in my opinion, is magnesium shavings - you can set it on fire even in the rain.

But shavings from resinous wood (preferably from the root of a coniferous tree) will do just fine; they also quickly ignite from a spark. We attach it to the flint and use it with pleasure.
