Скачать или смотреть Lesson 8, Scroll Saw Relief Cut, Importance of Angle and Direction

This video demonstrates the process of cutting a relief piece on the scroll saw.

Three factors determines the amount of raised or recessed relief, the angle, the direction of the cut and the size of the blade.

The smaller the angle, such as 3 degrees compared to 8 degrees, the larger the relief. A 3 degree angle will make a cut lift higher out of the original than 8 degrees will.

The direction of the cut will determine if it is a raised or recessed relief.
On a saw that tilts the work surface to the left a clockwise direction of cut will cause the cut piece to recess into the original surface. On the same saw a counter clockwise direction of cut will cause the piece to raise higher in relief in comparison to the original surface. If the saw tilts the opposite direction then the outcome is reversed.

The larger the blade then the wider the kerf (the width of the cut caused by removal of material by the blade) and therefore the higher or lower the cut piece will move.
