DUplICAtINg FlAt KEYs
Each graduation mark on the cylinder as shown at I-6 represents twenty-five thousandths of an inch (.025").
Now, with your micrometer setting on 0, turn it with your right hand to your RIGHT, one full turn. This repre-
sents .025" on the barrel markings. Notice that the barrel lines up with the second mark on the cylinder. Turn
it two more full turns and it now reads .075". If you turn the barrel five more points to the right, the reading
would be .080". Now, turn the micrometer back to 0 and we will reset the machine to cut flat steel keys.

It will be necessary to use a special guide to cut the steel keys since they have narrow slots and the guide used
for cylinder keys cannot be used. The guide must always have the same shape as the cutter. First, we'll remove
the file cutter by first removing the nut and outside collar. Install the slotting cutter for the steel keys on the
arbor. This cutter is packed in the parts bag. Be sure the teeth are pointing down toward you. Install the collar
and tighten the nut.
