The spacing will not be the same when using the slotting cutter since it is narrower, but we will not have to
change the lateral adjustment. STEEL KEYS CAN BE GAUGED OR MEASURED FROM THE TIP IN-
STEAD OF FROM THE SHOULDER.
Figure L shows how to set up for cutting steel keys. First, clamp the key L-1 in the right hand vise and then line
up the tip of the key with the guide as shown at L-2. The blank L-3 goes in the left hand vise. Line up the tip
with the edge of the cutter, as shown at L-4. Tighten the clamp. Check to be sure that the key is touching the
guide at L-2 and that the blank is touching the cutter at L-4. Now, duplicate the cuts in the key. Make the cuts
straight in. DO NOT put side pressure on this cutter. If the slot must be wider that the cutter, make two cuts.
Make the first cut straight in, all the way to the bottom. After you have all the cuts made, turn the key over and
make any additional cuts on the other side.

Occasionally, you will run into a key that has grooves made in such a manner that it will be difficult to clamp
in the vise. When this occurs, it will be necessary to improvise a small shim in order to squarely clamp the
key. Figure M shows a blank with very little on the bottom side. If this blank were clamped in a vise, it would
have a tendency to tilt down as shown in Figure M. By the addition of a small shim, as shown in Figure N at
Point N-1, this blank could be clamped in the vise straight and square. These shims are usually made of scrap
metal or wire. Figure O shows another type of blank that may cause trouble in clamping. The rib shown at O-1
causes it to tilt either up or down. O-2 shows a small piece of wire inserted between the key and the vise to hold
the blank squarely. Foley-Belsaw sells a Brass Key Shim (5749644) that works well for many applications.
