What happened to the good old High School Shop Classes??
Please be careful !!
Some Good Rules of the "uncut" Thumbs
1. Always keep the good section between the fence and the saw.
2. Never push the tail of a cut-off (scrap) section.
3. Always only push the piece between the fence and the saw.
4. Always use a Push Block that covers the material and that has a small
hook to laps over the near side of the material, the hook should be shorter
than the thickness of the material being cut.
5. Hold down and push the Push Block along and against the fence.
6. Never reach over, behind, or near the blade to retrieve scraps, stop the
saw.
7. Never use a fence to do a cross cut, use a miter slide, a cross cut is
where the resulting cut is on the shortest side of the resulting scrap.
Please be careful !!

^--------- Note: the hook on this end, which is used to push PCB material,
the PUSH BLOCK should be taller then fingers are long (maybe 4 to 5 inches),
length typically 8 inches long, width typically 3/4 inch.
A good Push Block has a hump on the top that fits in the palm of your hand.
To align the first cut with the PCB art work, clamp the PCB between to
straight boards, align the art work with the scrap edge sticking out between
the boards, use at least 4 screws from below for clamping. The boards should
cover and be wider then the non-scrap side of the PCB material. Use the
fence and Push Block to make a straight cut.
Please Be Careful !!!
