Osnova difficulty in creating a homemade drilling machines — making mechanism of vertical movement of the working body. What if you make a machine entirely without the mechanism to serve Chuck with a drill bit, and the item itself? In this case the structure is greatly simplified. No claim to originality for his decision, but it is this idea that allowed me to design and manufacture the machine, the device which is shown in the figure.
Novice hams are often hesitant to begin the Assembly of electronic devices just because in the description is missing the picture of the PCB, and to develop its own not everyone can. Indeed, without sufficient experience to make it easy: it is necessary to know how to choose the best dimensions to correctly place items in a timely manner to detect and correct errors. Therefore, we recommend you to master the design of printed circuit boards with the simplest.
This simple device can be useful to the house master in the manufacture of various frames, boxes, lampshades and other articles made from organic glass sheet, thermoplastic plastic or foam.
Handle to a file? What could be easier! Bought, planted a file, and you’re done! Well, if the file is too large size and its shank when the head is just going to break a normal pen? It turns out that the handle for the larger, so-called dracopoli file not so simple.
Even in a small room it is possible to allocate a place under a sports area, as required for the normal development of the child. “Club Home of the Masters” already familiar with similar structures; today, we offer another option, made entirely of wooden parts.
Remember: it was not cold in your house last winter? Do not rush to blame the heating system, even if it furnace: victoriat room can and Windows. Check to see if the putty on the frames and I wanna see if she cracks through the thin slit between the glass and the wood heat is rapidly going out of the house and cold air is not less noticeable comes inside. The measurements indicate, through window and door openings can dissipate up to 2/3 of the generated heat-generating appliances heat. That’s why remaining before the real cold days are useful to restore the integrity of window glazing. As describe in detail. Our tips will be useful for individual developers, and those who want to make a greenhouse or glasshouse.
Existing jigsaw has a number of disadvantages. Minor fluctuations in the amplitude of the nail (5 mm) does not allow to increase the speed of cutting both thin and thick plywood. Machine heats up quickly and breaks down. How to increase the amplitude of its oscillations? Indeed, in this case, the cutting speed is the magnitude of the advancing nail the plywood in one pass. The exit is found.
For individual construction is often necessary to make processing of logs for construction of wood with different cross-sections (beams, plates, boards). Due to the large weight of logs and the lack of a reference plane such processing conventional saw and planer (without additional equipment) almost impossible to do. This task I chose the following way.
I work in the locomotive depot of the station Yerofey Pavlovich, produce visual AIDS for teaching assistants machinists of electric locomotives. During the work on the stand pneumatic circuits I have not found a suitable tool for sampling grooves complex profile and decided to make a cutting tool that brings together in its construction, some carpentry. Thus was born the plane-“harvester”.
