good way to lose some digits but it looks like he had done this before
I don't think he's done it before.
Why do I think that?
Because he has all his fingers!
looks like he sets the belts up in the palm of his hand, then presents his palm to the pulley, keeping his fingers lower than the palm - similar to how you feed apples to a horse. - it looks dangerous (and yes I'd use a chicken stick or switch everything off), but I suspect some thought has gone into doing this "safely"
He probably would change a lawnmower blade with it running :smash: just plain stupid, this is a good video for OSHA. Mr Mikey.
I've seen similar videos of guys changing belts on VW Beetles. but they usually use a screwdriver instead of their fingers. Yikes
I had a sloppy drive belt on my bandsaw. I gave it a heel swipe with my hand, hand outside but my fingers must have been dangling a might. It grabbed me by my index and middle fingers. It was a touch bloody. I'm fortunate. My nails will be fully grown back in a 2-3 weeks now. It only stung for a moment. Old can act stupidly, too.
We had an older gentleman working in the blacksmith shop where I worked as a kid. The only way to change the speed of the drill press or stop it was while it was running. just take a stick and nudge the flat belt off the pulley then move it to the one you wanted then nudge it back on with the stick or the palm of your hand. Simple I did it sometimes a dozen or more times a day. Anyway MR Chanie needed to drill something, as he reached for the belt with his hand I yelled for him to take his glove off since that was how I was taught. He says to me boy I've worked in this shop longer than you have lived on this earth. It was a 30 mile drive to the DR. 2 hours later he came back and said next time I'll let you start that ***)(*)&)*&)*&)&*&)&)*&)*&)* machine My boss just laughed
I'm missing my two middle fingers on my right hand at the second joint from an accident with a table saw (almost lost my index and pinky too but I talked the plastic surgeon out of amputating...and I was right, it took me six years but they are working fine now, pulling a trigger and zipping a fly!) ....having said that...I don't see what the guy on the video was doing as nearly as dangerous as having a one second lapse on a table saw. :D:D
IMO table saws and angle grinders are more dangerous than a chain saw missing its chain breakQuote:

AND I've still got all 10...but seriously, very sharp blades and the knowledge of what's being cut and how to feed it and the sound of the cut will keep you on the 'right' side of safe...and I paint the table insert red so the brain automatically knows it's the danger zone. Now those pesky angle grinders, can't live with them or without them! I've seen WAY to many homemade 'attachments' for them that are flat out dangerous, particularly putting saw blades rated up to 6000 rpm, when the grinder goes to 11,000! On a recent stay in the ED at hospital, I asked an ambo about tradie accidents and he said, far and away the most common, was hand held circular saw cuts to arms and legs. Stay safe, even just for Mrs Frank! Cheers

That is extremely dangerous
In my early teens I worked at a local brickworks which had 6inch flat belt fast and loose pulleys below floor level. There was a one armed man who worked in a shed making hand made bricks (no pun intended) who I leaned had tried to remount a belt with the pulleys running, it tore his arm of at the shoulder. I tried make conversation with him to no avail as it affected him badly. At least the company kept him in employment.
That was common in machine shops, farming and pretty much any industry that had belts running everywhere. My mom worked in Greenfield Village here in Dearborn Mi., It was created by Henry Ford. He had restored buildings and showed how early America was built. Thomas Edison and many more are displayed here. It had a running machine shop with a steam engine that ran all the equipment with belts that ran from the ceiling pulleys and shafts to the machines. A worker giving a demonstration got caught in the belt. Sadly, he did not make it. Mr Mikey.
This guy's lucky he didn't knock himself out when his hand hit his face coming off of that belt!
