jamison - I think your missing the point of the podcast. They are showing what can happen if the board goes sideways, and believe me if it did that - you could not hold onto the board. The whole thing was a demo - that is why they had the plywood set up where they did. As you probably noticed all safety guards were removed from the saw.
he was purposley doing this to show the reuslts. he willing operated the saw incorrectly.Had he been operating the saw correctly I don't think that would happen.
