Had some kickback yesterday (nothing too bad and I never stand directly behind the blade) and it got me thinking. One of my side jobs entails me talking to people about TS and other WW tools. People often state that they can ‘control’ kickback and are quick enough to react. Let’s look at the numbers:
Average blade speed 3450rpm
A little math – and the circumference of the blade is 31.4159 in. (d pi = circ)
More math – that means that one tooth on the blade travels 108,384.855 inches per minute (circ rpm)
That is over 1800 inches per second.
It’s also a hair over 102 miles per hour. For our friends across the pond it’s over 165km/h!
Lets look at a scenario:
I cant wait until I can get a new saw with a true riving knife. On my way to go get a splitter now.
