Application

Application of these physical properties illustrate how these various principles and elements come together and work in harmony.
It is of great
importance that you are aware of the orientation of the teeth:
it will determine whether the pushing or pulling of the saw is the cutting
stroke. If the teeth are
pointing towards the handle (Fig. 9) the cutting action
occurs as the saw is being pulled towards you. On the
"cutting stroke" a slight downward pressure would assist in helping the teeth
bite deeper into the die stone and more rapidly advance the cut. Also
see illustration (Fig. 5).
As the
saw cut proceeds, observe how the gullets help carry the stone dust out of the
cut and how the set of the teeth create a wider curf preventing binding of
the blade and providing necessary clearance if you
want the cut to curve to the right or left .
As you push the saw away from you little or no cutting occurs. One
could consider the pushing (return) stroke an opportunity to relax your grip
on the saw and conserve energy . The process can be described as a
cycle, consisting of the cutting stroke and the return stroke.

I would strongly recommend that the model be
held in place with a model clamping device. The instrument in (Fig. 10)
is called "The-Model-Ease".
In addition to the benefits of rigidly securing the model it may also relieve tension in the
hand that would normally be used to stabilize the model .
