“From work saw burn until white!” — wrote Vladimir Mayakovsky in his poem “Whom to be?” Meanwhile, heat the cutting tool in the first place means that he is dull. In this case, the joiner, as of old, takes padpilot (triangular file — in modern terminology) and manually sharpening the teeth of a handsaw. Much hard work and unproductive work! But maybe, and this operation can be mechanized? There are also sharpening machines for milling cutters, disks of circular saws… However, here’s a review on the machine, developed by ninth-graders of high school № 28 of Ust-Kamenogorsk city under the leadership of teacher A. A. Boytsov: “bench grinder will find wide application not only in school workshops, but in the joiner shops of the construction companies and carpentry teams on any construction site.

I want to share my experience in the construction of the winter water supply for periodically heated garden (suburban) home. Operation of my water supply in winter 2012/13, when the temperature dropped to minus 35°C, showed its high reliability. Diagram of water is shown in Fig. 2. Water pipes laid at a depth of 30 – 40 cm, but do not require heating. The level of penetration is determined by considerations of labor costs and create minimal bias (of about 2 cm to one meter of pipe) in the direction from the house to the well.
The lamp has only three pipe parts: the bracket, the clip and the visor. The first two (see picture) made of steel sheet with a thickness of 1-1,5 mm (dotted line marked bend line). The visor is cut from galvanized roofing iron.
