The cache is very simple and very secretive. You do not need scarce parts and a lot of time to repeat it.
All you need to find is a cigar case. It is made of thin aluminum. And a feather drill. You can borrow this drill - you won’t need it for the whole time.

What can be stored in such a cache?


In a cache you can store money for a rainy day, jewelry, a USB flash drive with valuable data, etc.

How to make a cache?


First you need to attach a washer to the cover of the case, which will be larger in diameter than the fuller itself. It can be found or cut out with scissors for metal from a can. For fastening we use a bolt with a flat hat. In the case, pre-drill a hole.

Where will the cache be located?


The cache will be located at the end of the door from the top, so it is very reliable and it is unlikely that anyone will be looking for valuable things there.
We measure the diameter of the case from the cigar. And we take a pen drill slightly larger in diameter than the case. We insert into a screwdriver or drill and drill a hole. The depth of the hole should be greater than the length of the case.
Now you can try to insert the case into the hole - it should fall through. But the puck should stick out. To the puck also plunged into the tree - you need to make a small groove along the edge of the hole. This can be done manually by digging a screwdriver. Or take a larger drill bit and drill a little bit.

Then we take our container and lower it into the hole. He should lie flat and should not be visible. When closing the door, he also should not shuffle and do not rest anywhere.

How now to get our capsule out of the hole?


And we will get this capsule with values ​​with an ordinary magnet. We bring a magnet - the hat is magnetized. We lift and the capsule rises with a magnet.

That's it, now you don’t have to worry about values. Good luck
