Wearing a polishing plate - GIF

Those were my thoughts exactly Marv, why show students something they are better of not knowing about.

That video makes me uneasy. Getting tired in a plant happens a lot when you're doing repetitive jobs. All that operator needs to do to get hurt is miss placing the workpiece between the bearings and push against the spinning grinding stone. With it spinning down, it will grab the steel plate and pull down sending his head towards the wheel. Notice that he is pressing the bearing off-center. It wouldn't take much to cause a serious injury especially if you are doing repetitive tasks.

A safer alternative would be to mount a bar hinged to the floor with the bar holding the bearings. That would give him greater separation from the wheel.

OSHA approved right??? HA HA To me it's an unsafe way of doing something... If some how the plate got hooked up with a downward force the bottom brace on the belly gadget could remove your jewel sack for you... With out to much work one could build a spring loaded moveable arm coming off the base of the polish motor to do what he doing with his belly...

No gloves, breakaway single thread apron neck loop, cleaner knot end. Still not sure exactly how that plate is pressed against his, ahem, lower abdomen region. Is it really just those two metal strip ends on both sides? Is there a horizontal metal strip connecting them that we can't see? Maybe eliminate the neck loop completely for a better body mounted harness-like device.

Agreed that safety concerns are a perfectly essential final step, but they can be an impediment to early stage brainstorming.

Да, конечно безопасность прежде всего.
Но!! Оцените саму идею обработки. Ведь задумка отличная, а вот исполнение плохое.

I see he has a fixed steady rest just as I do, works great when I'm looking at something closer for my failing eye's!

I think the gloves are present to allow the rod to turn freely in his hands as it spins. If the gloves are removed, he will still need something more slippery than human skin to allow free rotation. Hand-held rollers might work but then we're into building complex jigs to do what much of the world would regard as a hand task.

This made me wonder if he can put strips of tape on his hands/fingers.

Maybe something as simple as a bit of manly hand creme (Goldbond?) would do the trick and be less finicky.

It doesn't really look dangerous to me. The only thing I would do different is to use cotton twine for the hanger loop instead of rope so that it would easily break away if somehow it got pulled by that leather surfaced stropping wheel. It looks less dangerous to me than the common operation of using a file to break edges on a part spinning in a lathe (never hold the file by the tang and don't stand in line with it).
