Pump drill

The pump drill,
It is the ancestor of the power drill.
It consists of a rotating shaft fitted with a bit at its end. A flywheel (a heavy piece at its base) is attached to it, together with a sliding crossbar with cords that wind around the shaft.
By moving the horizontal bar up and down, the shaft and bit are turned alternately in one direction and the other. This is the jeweller's drill.
Depending on the bit, it can drill wood or stone, cut ring-and-dot motifs, etc.
The history of the pump drill can be traced back to ancient Egypt, and it has remained in use to this day.
The drills I make are therefore jeweller's drills, with a marble flywheel (white or black) and a bit for cutting ring-and-dot motifs (hardened steel). The cord is linen fibre and the bit is set in resin, so it can easily be changed by gently heating it to melt the resin.
