SING THE PINS
For keys with narrow or thin stems one pin must be used (fig. 18-1 fig. 18-2).
For keys with narrow, thin stems, two pins must be used (fig. 18-3), the second one to give a secure
grip on the key.
ATTENTION: the diameter of the pin used for the original key must be the same as that used for the key blank,
so that the two keys are secured in identical positions in the jaws.
ATTENTION: never exchange the clamps.

Cutting pin keys

Almost all pin keys (with the exception of Y and T shapes) can be cut with ordinary or four-sided clamps
(fig. 6, page 8).
Positioning pin keys:
1) Leave the gauges in the idle position.
2) Insert the bars with neck into the slot in the clamps.
3) Rest the key stop against the bar in one of the three positions (fig.19).
4) Secure the original key in the clamp.
5) Remove the bar from the slot so that it is not touched by the tracer point or cutting tool.
6) Repeat the same procedure with the key blank on the other clamp, using the same position.
7) Cut the first blade.
8) Repeat the operation, turning the keys in the same direction for the other positions.
