And I really
don't fault the sawstop inventor. He was turned down by all the companies.

The whirlwind may succeed, since the manufactures missed the boat once.
They won't twice.

Actually the Sawstop inventor had the deck stacked against him,
somewhat by himself.

1. He wanted unreasonable licensing royalties.
2. The cost to re-tool and add the technology to existing
manufacturing process was way to expensive for anyone to go first.
3. The current manufacturers lawyers killed any consideration because
if you add this, you are admitting the thousands of saws you sold
without it are dangerous. And if you offer it on one saw and not
another, even worse when you get sued from someone who bought the one
without it.
