Abstract
A method for use with a power saw having a frame with a first blade rotatably mounted thereon, the first blade having a cutting edge with a maximum first thickness. A light source is mounted on the frame. An opaque barrier has a first slot with a first width. The opaque barrier is positioned in alignment with the light source such that light from the light source passes through the first slot and shines on the first blade so as to produce a shadow of the first blade. The method includes exchanging the first blade with a second blade, the second blade having a maximum second thickness. The opaque barrier is adjusted such that the first slot is replaced with a second slot having a second width, the second width of the second slot being greater than or smaller than the first width of the first slot.

A method for use with a power saw having:
- a frame with a first blade rotatably mounted thereon, the first blade having a cutting edge with a maximum first thickness;
- a light source mounted on the frame;
- and
- an opaque barrier having a first slot with a first width, the opaque barrier being positioned in alignment with the light source such that light from the light source passes through the first slot and shines on the first blade so as to produce a shadow of the first blade;
- the method comprising the acts of:
- exchanging the first blade with a second blade, the second blade having a cutting edge with a maximum second thickness, the second thickness being larger than or smaller than the first thickness of the first blade;
- adjusting the opaque barrier such that the first slot is replaced with a second slot having a second width, the second slot being aligned with the light source such that light from the light source passes through the second slot and shines on the second blade so as to produce a shadow of the second blade, the second width of the second slot being greater than or smaller than the first width of the first slot;
- and
- wherein the first and second slots are selected based on the first thickness or second thickness of the first or second blades such that definition of the shadow is maintained.

- a first opaque barrier having a first slot with a first width, the first opaque barrier being positioned in alignment with the light source such that light from the light source passes through the first slot and shines on the first blade so as to produce a shadow of the first blade;
- the method comprising the acts of:
- exchanging the first blade with a second blade, the second blade having a cutting edge with a maximum second thickness, the second thickness being larger than or smaller than the first thickness;
- replacing the first opaque barrier with a second opaque barrier having a second slot with a second width, the second slot being aligned with the light source such that light from the light source passes through the second slot and shines on the second blade so as to produce a shadow of the second blade, the second width of the second slot being greater than or smaller than the first width of the first slot;
- and
- wherein the first and second slots are selected based on the first thickness or second thickness of the first or second blades such that definition of the shadow is maintained.

- and
- wherein the first barrier and second barrier slots are selected based on the first thickness or second thickness of the first or second blades such that definition of the shadow is maintained.
