Tractor with Car-Like Comfort

Homemade D-144 tractor: frame, axles, clutch

I have long been a fan of the magazine “Modelist-Konstruktor”. Back in my school years I was into aircraft and rocket modeling and made kites. Small-scale mechanization also attracted me. I dreamed of some kind of tractor, especially when I had to dig the garden by the house by hand. After graduating from the institute, Read more…

The Diesel Legend “Indy”

Cummins Diesel Special slot-car model build guide

The prototype of this slot-car model (for how to build a simple home or school track for model-car racing, see “M-K” No. 3, 2025.) was the Cummins Diesel Special racing car, a participant in the 500-mile race of 1952 on the track in Indianapolis (Indiana, USA).

The Golden Collection

Soviet homemade Gran Turismo: KD, Gepard, GTSh, YUNA

According to the “table of ranks,” the Gran Turismo class covers comfortable, high-speed cars in a sporting style, intended for long-distance travel on motorways.

Silent Rumble

DIY electric vibrating screen for bulk materials

When building country cottages or garages on a homestead, you often need to screen bulk construction materials, soil, or garden earth. For this, a special fixture is used — a so-called vibrating screen (grizzly). Its classic version — a frame with a mesh set on trestles — is very bulky and low-productivity. I tried to Read more…

Bottle Flotilla — 3

Catamaran with rotor wind drive from PET bottles

We have already described the construction of a sailboat and a vessel powered by a rubber motor, using PET soda bottles (see “M-K” No. 5 and 8 for 2024). We suggest adding to the “bottle fleet” a catamaran model with a rotor wind drive. It has long been observed that if a rotating cylinder is Read more…

For Furrows and Pits

DIY electric tiller-cultivator and hole digger

Soil cultivation with electric tillers is nothing new. Especially for owners of summer cottages, gardens and vegetable plots (see, for example, “M-K” 3’83, 11’90). And when prices keep rising, when using walk-behind tractors (not to mention scarce mini-tractors) sometimes becomes economically impractical, electric helpers on small land plots are, so to speak, beyond competition. Convenient Read more…

A PUMP CONNECTED TO THE SUN

Rice. 1. Scheme of the water lift by P. Radchenko.

No one in the small gardening cooperative near Bryansk suspected anything miraculous. The gardeners had only one thing on their minds: extracting water from wells. In hot weather, every able-bodied resident was tied to the heavy handles of cast-iron pumps. They had to pump bucket after bucket to water the thirsty seedlings. One of the Read more…
