What you will need:

used oil filter, thread locker, can of paint, six round head screws, coin, fire source.

The first step is to calcine the oil filter in a stove or over a fire. This is necessary so that all remaining oil and paint burn out. As soon as the object has cooled, we arm ourselves with a grinder and cut off the steel ring from it. We remove from the internal space the remains of the filter element (they will be charred), the spring, the safety valve and other removable elements.

For further work we only need a metal case and a ring. In the upper part of the former filter, using a drill, we make holes in the upper part of the housing on each of the faces. Next, using a drill, we drill out the spot welding spots in the bottom. Using a tap, we make metal threads in the holes made.

We screw one screw with a round head into them through one hole. After tightening them, we cut off the hardware from the reverse side. All parts can be coated with heat-resistant paint during operation. The filter element cover must be pressed into the base, and a coin or a suitable steel disk into its central hole.

Now you can grind the outer sides of the case, after which the heater base is installed with three screws. The heater is ready. It is best to use tea candles as fuel. Detailed assembly process in the video below.

Drill attachment

Using an oil filter, you can make a cutter that will allow you to drill through various materials, such as wood, plastic, and drywall.

In this case, we also work with the lower part of the filter, forming teeth at the end.

Then we make a hole and fasten the bolt - our nozzle is ready.


An oil filter cutter is perfect for creating holes when installing sockets and laying wiring

Tent heater

Sometimes it is so necessary to slightly warm up the interior of a fishing tent in winter, or a tent for relaxation in the damp autumn or spring. But doing this for a number of reasons is not always easy, and therefore the topic of heating is present on every fishing forum. In winter and summer there is a discussion of various types of fireboxes and burners. For myself, I chose probably the simplest version of the stove from a car oil filter.

I didn’t bother with used filters and bought a new one for 190 rubles.

The appearance of the heater turned out to be quite cultural. I will indicate operating time, efficiency and various shortcomings after testing in real conditions.

I won't calm down. It will be +5 or less outside and rain. And what do you want me to do? Okay, as a last resort we will heat ourselves the old fashioned way, but it will be far from comfortable...

Why do you need a heater in a tent? Mainly to keep warm while sleeping. It may be enough to provide warmth inside the sleeping bag - an ELECTRIC HEATING HATTER will do! There are different types of them: electric sheets (size 50-80x150 cm, square heating pads 40-50 cm in size, and “capes” for a car seat. All this is available for 220 and 12 volts. I’ve been using electric sheets at the dacha for many years. Very good !

Not “tents”, but tents. Sit warm in the evening. Things so that they don’t get damp... Or is it old age 8)

Mobiba camping baths (tent + stove) to help you!

Can anyone tell me where to buy a wood stove to heat a tent? Or a design that can be made without major engineering problems?

Andrey, you most likely cannot do without engineering problems - cutting, welding pieces of metal. The result will be at least the same stove as shown in the report on the last exhibition. Although there are some ideas. I just have a couple of pieces of (stove) stainless steel pipe with a diameter of 120 mm. You can build something based on the principle of a samovar.

Yesterday I tested the device in the field. The temperature outside was from 7 to 12 degrees. There are no exact data on temperature changes in the “room”. I found out: the candle burns until it is fully used for 2-2.5 hours; if the heater is placed under a camping chair, the effect is more expressive; If you hold your hand just above the candle at a height of 12-15 cm, then almost no heat is felt, while the stove lid is very hot. https://photo.qip.ru/photo/river-nightmare/200961426/xlarge/109748738.jpg In weather like yesterday, the heating of the tent came mainly from the peeping sun. But in winter or at night the benefits of such a stove will be more noticeable.

The need for gentle heating became clear after an overnight stay in Yashkin's backwater from January 18 to 19 of one year, when the worms froze in a sleeping bag and a very recent epic on Kalmynka https://fishing.ahtubinsk.ru/2015/04/11/neobitaemye-ostrova -dikie-ozera-i-zlye-shhuki/ . A gas stove raises the temperature very effectively, but burns all the oxygen and then your head hurts like after an alcohol extinguisher and you don’t want to sleep with gas at all. I want to see the next sunrise. Dry fuel burns well, but it has a smell and some residues fall out from it. Candles of various designs have been used for heating for a long time. There are also all sorts of wood chip stoves, but they smoke and they need a chimney, and this is a problem that can be solved in a tent. I had a tourist primus “Bumblebee” from the USSR, but because of old age, the gas in that one went the wrong way and it looked very scary. Now it lies in the garage. I will continue to experiment with heating

Unusual glass

If you want to surprise the car owner, then present him with a glass of rum or coffee made from an oil filter.

Simply saw off the bottom of the filter and give it a neat look.

Don't forget to wash the filter well and warm it thoroughly to make the surface as clean as possible.

Now strip off the old paint and polish the surface. A stylish and creative glass made from a car filter is ready.

You shouldn’t throw away old things that at first glance seem completely unnecessary. Sometimes you can make quite interesting, original, original crafts from what’s lying around in the garage. It can be anything - the main thing is to show your imagination and make a little effort. Often you can get not only beautiful, but also useful devices that can be an excellent gift with or without an occasion.

For example, hikers will appreciate a portable heater or mini camp stove made from an oil filter. All that is needed to create such useful things is a used part, which many simply throw away after replacement.

How to Make a Tent Heater from an Oil Filter in Four Steps

When going on a camping trip or overnight fishing trip, you must provide for the possibility of heating at night. After all, even in summer the nights can be very cool, sleeping at low temperatures is uncomfortable and even dangerous, as you can catch a cold. It is impossible to make a fire directly in a tent for safety reasons, but making a simple heater is quite possible and inexpensive.

For it you will need:

  • Oil filter from any car;
  • Drill and drill bits;
  • M6 screws with nuts – 4 pieces;
  • Metal corners – 4 pieces;
  • A piece of galvanized steel;
  • Kern;
  • Pliers;
  • Scissors for cutting metal;
  • Dry fuel;
  • Grinder.

Assembly consists of four stages

Oil filters for cars come in long and short versions. It is preferable to choose a large filter so that more dry alcohol can be placed in it. This will increase the heating effect.

All internal parts are removed from the filter. To do this, you will have to disassemble it by grinding off the curved edge on a sharpening machine. Work should be carried out using personal protective equipment and observing safety measures, as sparks and metal will fly in all directions. It is better to wear glasses and a respirator.

When all the parts are disconnected, the filter is washed from oil and a heater body is made from the bottom and lid. There is no need to invent anything here: the bottom already exists. There are two holes in the filter that will serve as air intakes, with their help the fire will be maintained. But you need to drill four more holes for the leg screws.

Before drilling, the hole points should be punched and machine oil should be dripped onto the drill. It is important not to pierce the filter, for which purpose a piece of thick board is placed under the workbench.

Holes are also made in the lid for proper air convection inside the device.

The heater needs a lid to avoid leaving an open fire. It is made from a piece of galvanized sheet. A circle with a margin is cut out with scissors, the edges are bent with pliers, and tightly attached to the filter mesh.

The filter has a second bottom without holes. They need to be drilled, as in the first bottom. Four metal corners, which will serve as legs, are attached to the bottom with M6 screws and nuts.

The homemade heater is turned over and placed on its legs, and a second bottom with dry alcohol is installed on it. You can also use a thick paraffin candle, but the heat will be less. The fuel is set on fire, covered with a mesh with a lid, and another large lid is placed on top. The fire in the heater burns due to the flow of oxygen into the openings of the lid and bottom.

Such a mini-heater will be a useful thing for lovers of night hikes and summer outdoor recreation. Not only will it help you stay warm on cold nights, but it will also repel pesky mosquitoes. You just need to use a homemade device, observing all fire safety rules.

DIY portable tent heater!

I can imagine that the fishermen are all clutching their stomachs with laughter))))))). I use this thing for winter fishing, I bought it for 350 rubles at the market. It heats up and you can fry freshly caught fish.

a large gas cylinder for burners costs 250 rubles. on a small fire like a candle should be enough for a couple of nights, or even more.

Just for cooking three times a day, such a cylinder is enough for 4-5 days.

There are easier ways. For example, here pots are used to increase the heating area. But the issue with carbon monoxide has not been resolved (there is no outlet). A hose (corrugated hose) twisted into a spiral and placed outside would be more effective. You can also talk about the African refrigerator - the same two pots inserted into each other, the space between the walls of which is filled with sand or earth and filled with water, then the temperature in the inner pot will be 10-15 degrees lower than the surrounding one.

Making an oil filter puller

Having shortened the candlestick a little, we cut grooves with a depth equal to the width of the belt and a width equal to the thickness of the belt folded in half. I also found a washer with a collar that fit perfectly with the diameter of the candlestick.

The belt puller is ready. It is easy to turn with a head with a suitable size knob.

For a chain puller, we disassemble the chain. You can file the pin and knock it out, but I used a chain squeezer, which I also made myself.

Having taken out the insides of the ratchet, we cut its ring approximately in the middle. We sharpen one side and weld two jaws from the chain to the other.
