I’m probably not mistaken saying that the majority of home handymen’s dream is to have a universal bormashenko. How many opportunities it opens! Engraving, abrasive machining of parts of complex configuration, the manufacture of dies and molds, drilling and countersinking holes located in hard to drill places, jewelry work — this is not a complete list of operations to perform which allows this mechanism. It is not surprising that bormashenko, due to its large SROs, it is not easy to get.
However, this mechanism can do it yourself. Offer made relatively simple design bormashenko on the basis of the electric drill.
First of all, you will need a floppy drive. I recommend to use for this purpose, the cable of the speedometer — it will not be difficult to buy in any store of spare parts for cars and motorcycles. I used a flexible shaft of the speedometer of the motorcycle “IZH”, type GW 119A-01, under which all shown dimensions. This detail operational requirements answered in full, and improvements almost never required, only had to cut the threads of M16 on the surface of one of the lugs of the shell (Fig.1). With equal success it is possible to use cables speedometers and other types.
