made from cast iron, so it’s our only choice for attaching
the magnetic base. On larger milling machines, I use the
milling head as they are made from cast iron as well. Make
sure you place the indicator base so the table won’t hit the
test indicator arm or base when it moves (Figure 10).
Position the test indicator probe on the leading left
edge of the rear jaw as shown in Figure 11. I like to set the
probe against the jaw, then move the indicator so that it is
an additional 1/8” towards the jaw. This gives me the play I
need to make adjustments.
Move the jaw to the right end (Figure 12) and back
