Drilling metal is not a very difficult task, but in order to do it accurately, correct marking is needed. Conventional punches are very convenient to work with, but sometimes a hammer blow occurs with an offset, so that the mark is also shifted. A repeated kick can correct the mark, but the drill still has to go to the side.
In order to eliminate the error in the marking and notching there is a very simple method. I bring to your attention a spring center punch, for which you do not need a hammer. Notching is done by stretching and releasing the spring. Since the spring always moves in a straight line, the impact is always exactly along the axis. This master class shows how turning work is done without a lathe. For this purpose, an electric drill and a engraver drill are used. The main materials are bronze, brass or steel. Also we need a tightly wound spring with a length of 60-100mm. As a striker, a special nail is used. Metalworking is only at first glance difficult. In fact, everything is done very simply.
