The snowmobile’s reliability and low maintenance match the very highest requirements imposed on a vehicle intended for autonomous runs across Read more…
One day I came across an article “Vitamin jack” (“M-K” No. 7 for 1985), where the author writes that when preparing juices he crushes apples with a wooden mallet in a small barrel.

The city of Arsenyev in Primorsky Krai is not that close to the sea. However, the now widely spread passion for sailing on sailboards — windsurfers — led to the appearance of a section here in 1976. There are now about thirty people in it. They started, as they say, from scratch. They read specialized Read more…
It is generally accepted that the drill is the main tool of home handymen, hobbyists who like to build things with their own hands for the home and family, and also the primary means of mechanizing labor-intensive processes when building homemade machinery.
