Some of you will have seen this and some not, its scary I couldn't even watch it he was lucky.
Be safe..
a 10in (250mm) saw blade has a peripheral speed of over 100mph
Great! Another genius using a saw without a riving knife, or a crown guard, and with a rip fence that's too long - at least he's using proper push sticks (even though they are a tad on the short side)! Sorting out that "misalignment" still won't save you from having a kickback, though, a "short" rip fence will get you a lot further. Worst kickback I ever had was ripping some 10 x 2in kilned black American walnut a number of years back: the stuff was so full of stresses that it twisted in around the back of the blade and even with the riving knife and crown guard I found a 12 foot length of walnut being propelled backwards past me at a rate of knots. Fortunately I was standing in the right place, to one side, rather than directly behind the stock so the min damage was to my pride. That was a 16in rip saw with a 7HP motor, so it imparted a fair amount of energy back into the timber - enough to fire it about 20 feet across the shop. I have to say that it was a rare incident, but it's not the only kickback I've had over the years - but I don't have many.And then some! A 250mm blade at 2950rpm comes to 173mph!
You might like this, too...
IIRC there is a yank brand of saw that will cut out as soon as it detects flesh on the blade.
your finger will be very badly damaged even with that system
where as a finger will not
