5. If you already know the degree of notch, use the pointer on the scale to set the angle.
If you used the sliding “T” bevel method from step 3 record the degree for future
notches.
6. Clamp your tubing in the vise. Stick just enough tubing out the cutter side of the vise
to complete the cut.
Be sure that there is enough tubing sticking out to avoid the
cutter contacting the vise before notch is complete. This will minimize deflection
and give the best cut. Tighten the vise handle by hand. Over tightening will cause vise
damage and may deform your tubing.
7. If you have the ADJUSTABLE HEIGHT vise, and need to make an OFFSET notch,
you need to set the jaw height. This height is set by turning the adjustment screw in or
out to get the correct position of the tube in relation to the cutter. The vise must have
light pressure on the tube when making adjustments, just snug enough to center the
tube in the jaws. Be sure to lock the adjustable jaws once the height is set, using the
indicated screws. Once the height is set tighten the vise as usual.
