clamp block from the bottom of the steady
rest.
2. Clean away any debris or grime from the
bedways, the steady rest ways, and the
clamp block.
3. position the steady rest on the bedway so the
triangular notch fits over the rear angled rail
of the bedway, as shown in
figure 42, then
re-install and tighten the clamp block.
4. loosen the lock knob, swing it out of the way,
then open the steady rest to fit the workpiece
