He states plainly in the video that he removed the stock riving knife/anti kickback, dust hood, because the part was too tall to fit beneath the hood/pawls. Its a modern saw, and has a riving knife. Im sure he is well aware of what he did wrong, its kind of admirable that he's willing to post what most of us would hope never see's the light of day.
Not defending the saw or his actions, I would never own a Sawstop for myself either but if I had a bunch of guys running saws, regardless of their espoused expertise and experience, I would most definitely have them on the shop floor.
I would venture to guess, if they havent already, insurance companies will painfully nudge you in that direction anyway.
Not long ago a picked up a machine purchased from a shop and in a conversation about spray booths with the shop forman (a young man) where OSHA came up he held up his right hand with freshly removed stitches of index, ring, and middle finger severed off at the hand. He was left with a thumb and a pinky. They had re-attached and they didnt take. Scenario was the typical late in the day, knocking out a few parts that they cut routinely, and poof. Im sure my face literally turned white seeing the hand not for the thought of losing my fingers but being the shop owner and having to live with that happening to someone.
We've all read the endless sawstop diatribes. With the average level of individual I have in the shop, there should be one out there but with a slider and being lucky that I am in the shop, and with CNC, I am able to do 95% of the cutting and anything they cut on the slider hands are feet away from the blade.
