STATIONERY IN… DRILLS

STATIONERY IN DRILLS...It would seem that can be the total electric drill hole puncher, washing rubber (eraser) and a paper clip? But O. Lavrov, who considers himself a graduate of our magazine, was able not only to see it shared, but make stationery to work successfully in a number of original technical solutions. As a result of normal (and battered) drill inquiring of homebrew has expanded its typical “drill-tocil-wide” function. Now she can, if necessary, and tighten screws to Unscrew, and if you really itch — even a jigsaw or hacksaw would work tolerably well. All you need is the right tooling (this material is not considered).

Confirmation of steady growth in popularity, as well as the immensity of the topic of technical solutions for the production and practical use of “valuable gaseous product vyrobni (i.e., occurring without oxygen) fermentation (re-Pravaya) of the organic substances, previously falling under the category of worthless garbage”, and it is this article.

TRACER-CERTIFICALE

TRACER-CERTIFICALEThe second bread is often referred to as potatoes, thereby emphasizing the critical importance of this culture. But the complexity of cultivation, especially in individual sites, it is far not on last place. Especially if all the work done here the old fashioned way, without any mechanization. To make the gardener’s life is designed by me designed the device, which simultaneously performs two functions: tracer and planters. Seeing the art project at work, neighbors one and all, longed to have the same (boost, by the way, almost three times the productivity in the trace-landing) or equivalent for personal use. Only here to satisfy that request is not possible: no now I have neither the time nor the appropriate materials. But there are sketches in which (see Fig.) anyone can personally to make this accurate (and the main thing — quite efficient) a copy of any “mechanical wizard”.

ASSISTANT WELDING

WELDING ASSISTANTThank you so much, friend magazine, for the development of welding transformers. Inspired by the publications took a chance and made themselves compact, but quite powerful “svarochnik” based on “on the margins” of the burnt stator from a induction motor. Now that dream is about as good design of the rectifier… help me out, dear journal. On you one hope!
