Saw a live demo in Atlanta, he ran that hot dog into the saw blade alot
faster than you would cut any piece of wood. He shoved a sled with the hot
dog on it as fast as he could into the blade, not cutting the sled it was
already cut the same size as the distance the fence was set from the
blade. Hot dog only had a nick like the demo


My question is, would there be adequate protection if all that
happened is the blade dropping (or being pulled) below the table? It
seems to me that you might actually get pretty close to the same level
of protection without a system that destroys your blade and cartridge.


If there is 3 inches of blade exposed it takes .13 seconds for it to drop
below the table assuming it's being dropped by gravity with no friction and
no power assist. At that exposure when your finger touches the blade it
will be 4.6 inches from the centerline. To reach the centerline with .5
inch of blade still exposed your finger would have to reach the centerline
in .11 seconds. That means moving 41 inches per second or 3.48 feet per
second or 2.38 miles per hour. While you might not want to move wood that
fast, that is less than a slow walking pace, so moving your hand into the
blade that fast is _very_ easy to do.
