Back when I was an apprentice I noticed that prolly 50% of the journeymen were missing a digit or 2 (or more), As time went on I found a mentor......he had all his digits. We were running 18 X 18 X 48 inch blocks thur a band saw about the size
of a truck on end........the sweat was running down the crack of my ass.
The sum***** sounded like a locomotive on highball.
Part way thru a cut he reached up and shut the thing down......he was pushing & I was catching. I gave him a WTF (respectfully). He said the blade was cracked, did ya notice the blade was jumping just a bit?......well ......yeah.
He says when it snaps this blade (about 4 inches wide & 30ish feet long) will come
out of there big chunks at about eyeball level. Sure enough the blade was cracked about 1/4 of the way thru. Iza't why so many of your buddies are missing fingers I sez. No this thing will take off an arm....or your head. Thus began my education on running power equipment. My digits have some scars but they still are all there.
BTW, I would no more use a push block like the one the guy used in the vid than I would sit on that blade. Mine are all about 15 inches long and made from wood.
I've never had a kickback (knock wood
) but my push sticks get remade regular like. Like my mentor Lloyd said :"Them guys were stupid."
