Preparation of lubricating oil

Various smaller machines require to lubricate its metal elements very pure oil, in addition to this is usually recommended Bone oil. However, not to mention the fact that it is relatively expensive, it does not always easy to get prkticheski. Consequently, we consider it necessary to bring a subsequent unsophisticated means of cooking is very good lube. Take high glass container (jar) is poured into it for 2/3 of good vegetable oils (such as sunflower) and dipped to the same lead plate: the larger the surface of the latter, the better, because it is most expedient to give it a cylindrical shape (pipe section) . Height of the plate must comply with the level of oil, as the oil should come into contact with its entire surface. The vessel was then close the lid tightly put it on 2-3 moon in a room, where he was subjected to shaking: for all the pores of impurities oil partially settle on the surface of the plate, on the bottom part of the vessel. While the plate is carefully removed and poured into the oil vessel is newly used for storing oil. Purified in this way the oil can completely replace expensive Bone oil.

Grease the wheels of machine

Take the 200 elements of rapeseed oil, 1 share of mercuric chloride added water, at the discretion of, boil at a constant cross-linking over an open fire until saponification. The vessel was then transferred to a steam bath water was further added 100 items vaseline oil, 150 parts of bovine fat as 30 elements hoist

Grease for broaching presses

Dissolving 5 kg of soap in 5 liters of water and heated the solution up to 60 "C. Mix in 3 liters of wood oil and 2 liters of glycerol. The resulting jumble added 500 g of strong ammonia also as hot water to a universal container mixture turned 25 liters. Refers in a heated state.

Grease for sealing valves

In order to prepare a sealing composition for cranes, we recommend to take 2 items of fat and 2 pieces of wax and mix. The mixture for the use of glass tubes is prepared by mixing together equal elements of glycerin added paraffin.

The lubricant is used in cutting screws

1) A mixture of rapeseed oil or melted lard with turpentine.

2) A mixture of rapeseed oil or melted lard with a liquid mineral oil.

3) A mixture of rapeseed oil, blubber soap or with a concentrated soda solution, such as boiled oil 1 fraction also mixed with 10 parts of soda solution.

Grease is used at drilling very hard steel

We recommend the following composition: Mix 1 part of camphor alcohol with 4 parts of turpentine, they pour steel and allow some time to stand up.

Oil for sewing machines

Take 1 share of rapeseed oil is heated up to 50 "C and mixed into 3 elements of vaseline oil.

Purification lubricants

If lubricating oil former used contains little slime or metal particles, it does not lose from that its properties can also be used on, after purification by these contaminants for this purpose collected oil in particular tanks, in which the valve is located on the heights 5-10 cm from the bottom because the impurities sink to the bottom. The deposition of metal particles as an attack can be accelerated if the tank in a warm place. The oil discharged from the container still is filtered through 2-3 layers of fabric or flannel, and a layer of fabric each against one another at an interval of 6 cm. The fats of animal origin additionally vegetable oils progorknuvshie result of using either acidic give cause to deteriorate corrosion also at surfaces pins. Therefore it is necessary to destroy the acidity of such oil that is best achieved by washing them in lime water. Refined oil thus floats on the water surface may also had to be used again.

Putty for fastening steel equipment in the stone can be prepared by the following recipe (in weight fractions): Mix the dry ingredients - iron filings (100), gypsum (300), ammonia (5) also bred this mishmash of 9% sodium, the so-called dining , vinegar (40-60) until the desired consistency. The resulting putty used immediately.

Safety-putty prevent accidental unscrewing nuts, replacing the different lock washers. Talc nitroemali kneaded in a ratio of 1: 3 and diluted until the desired consistency or acetone solvent nitrokrasok.
