At first, like most beginner radio amateurs, I drilled the mounting holes in printed circuit boards with a universal tool — an electric hand drill. However, it turned out that for making small holes (less than 3 mm in diameter) and with high accuracy, a hand drill is a poor assistant. After breaking quite a Read more…
In the household there is occasionally a need for longitudinal sawing of long boards into beams or battens, trimming chipboard (particle board) to size, or performing similar operations with other comparable building or furniture materials. Anyone who has done such work with a hand saw knows how tedious and laborious it is, especially when several Read more…
A jigsaw is a common tool. However, when working with it, one often runs into certain difficulties: the blade breaks, slips out of the clamps, and when cutting along a curved contour it often twists, which makes it hard to keep the desired direction. It is much more convenient to use an electrothermal (hot-wire) jigsaw, Read more…
Wood burning is very often used for finishing wooden items. Even when this operation is done with a special tool—a pyrograph—it is very labor-intensive, especially when applying various complex ornaments. I would like to suggest a successfully tried mechanized method of burning complex patterns and various appliqués. It is much more productive than the traditional Read more…
This machine, operating from a single-phase AC network at 220 V, was manufactured in a technical creativity club at a lyceum. It turned out to be compact and convenient, meeting safety requirements. In addition to drilling holes and countersinking, the machine can also perform simple grinding and milling work using various attachments. The machine has Read more…
Every DIY enthusiast regularly faces cutting sheet metal and non-metallic materials. Using hand shears is inefficient (especially for large sheets): with high labor costs, the cutting quality leaves much to be desired. At one time, I used factory-made lever shears for metal. However, unfortunately, they had a not very reliable design, and when trying to Read more…
This machine will become your assistant if you are engaged in modeling or simply love to tinker. Even at home, there is often a need to cut a rail and plane it or sharpen a tool — all these operations are “within the power” of the machine I made. It is small — dimensions 80Х180X360 Read more…
A circular electric saw is a very useful thing in any household. In terms of usefulness, it is probably in second place after an electric drill. About the design of the electric saw: it couldn’t be simpler. Its basis is a DAO-A type electric motor from a washing machine. The electric motor doesn’t have to Read more…
My fifth-grade grandson recently came to me with a request: he needed to come up with a project for 3D printing, the kids from the internet would download toy soldiers, but he wanted to make something useful – could I help? A tin can caught my eye. – Try to find the center of a Read more…
It happens that a stud or tap gets cut off or broken, remaining in the hole. An unpleasant situation, but not hopeless. A proven technique will help: the hole needs to be drilled out to a larger diameter that allows extracting the fragment, cutting a thread in it, and screwing in a bushing for a Read more…
