Like it or like machine grease and the saying “porridge oil will not spoil” is applicable in the technique not always. Excessive amount of it even at nodes where the friction should be minimal, is not of benefit. But if oil gets on the friction parts of gear, the mechanism may deteriorate. Those who greased intopractice of the tape or the mechanism of EPU, knows what precision is necessary to carry out this operation. Conventional oil can do.CUTTER FOR ADHESIVE TAPE
Sticky tape is recently widely used. PI need to pack anything, connect, restore, attach — we resorted to duct tape. If you make a simple device for cutting the tape, use the roll becomes a lot easier. This will require a chip of the old saw blade and drugstore gum in the tube. Such a Read more…



You have conceived to make their own hammock for the garden, fence for a playpen or cot for baby — in all these cases, can not do without a grid. And to tie it yourself is not so easy: you will need a special device in the form of a hook, and need to know the appropriate technology for the job.
to Build a simple ship models — hobby many guys. With the onset of warm days on the water bodies appear whole flotilla of tiny boats, catamarans, yachts, rafts. But the trouble is that many of them can “walk” independently. Want an easy economical engine.
Built a similar machine I used. But this is considered the most successful. Layout scheme it is similar to a tractor “Belarus”. The engine of the motorcycle “Ural”. Electrical sectiontwo, but modified Instead of the standard ignition circuit breaker has two—one for each cylinder. Ignition coils B-110 also became two.
In mechanical engineering, and especially in the construction of the pipe installation is often associated with the need to weld them to the flanges or rings. To maintain precise perpendicularity them to the tube axis is not less important than to achieve high quality weld.

Readers familiar in № 4’2006 a tractor trailer Muscovite V. Wheels, interested and yourself mini-tractor for this Amateur designer. Today we publish the description of technology of manufacture of this tractor and schematic of its main components.
The Yak-130 is designed for replacement of the main UTS of the Russian air force L-39. First flight on a double Yak-130D (“Demonstrator”) with two engines RD-35 took place on 25 April 1996. In the production of Yak-130 established new engines AI-222-25 with a thrust of 2500 kg and designed and implemented a fully digital “Board”. The Yak-130 is equipped with an integrated digital-wire control system allowing, for training purposes, to change its characteristics of stability and controllability, depending on the type of the simulated aircraft.
