Often, while working on a model of a ship, I have to drill holes with a diameter less than one millimeter. To this end I have produced a handy drill machine. Maybe someone wants to make one for myself. To collect it is very simple, since it consists of the motor and of the two parts: collets & nuts collets. The collet and nut are taken already ready from of a compass. It only remains to drill at the end of the collet hole diameter of the motor shaft, push it on the shaft and solder. The battery and electric motor from any child’s electrohouse. O. MOROZOV, Bryansk
