the interesting part is if you took that same table saw and slowed the blade down say 1/3 to 1/5 the speed you would not have the danger amount.
I appreciate the effort, however misdirected it may have been, he took to show us just how quick and dangerous kickback always is. Yes, all tools have the potential to hurt or damage the user, it is just the power assisted ones will do more and much quicker.

Lets put things into perspective shall we?
A 10" table saw blade spinning at 3650 RPM. The blade is traveling at 108.58 MPH.
A 1" pen blank spinning on your lathe at 3650 RPM. The blank is traveling 10.8 MPH.
A 1" pen blank spinning on your lathe at 1,500 RPM. The blank is traveling 4.46 MPH.
A 1" pen blank spinning on your lathe at 800 RPM. The blank is traveling 2.37 MPH.
A 3/8" brad point drill bit recommended speed on a drill press is 1800 rpm in soft wood and 750 rpm in hardwood.
In softwood that is 2.00 MPH
In hardwood that is 0.836 MPH
See the difference?
