What is he grinding and why?

(Yes, I know half of you already know. I can't keep my mouth shut.)

[Jack Jones]

Because he could?

[Arefin Bari]

He is grinding something down because that part needs to be grinded?

He does have a safety goggles on. But he isn't safe. He is sitting comfortably on the table and trying to hold a small piece that he is grinding down. Do you know that a small mistake can make him lose a finger? I would like to encourage every single person to be safe when they are using a machine in the shop (everyone who reads this). Thanks.

Yes, sitting down with any type of powered tool is bad. Also, the grinder does not appear to be mounted to the bench, and it is surrounded by excess "stuff." I don't want to be the "downer" on this picture discussion but I'm seeing some things that are generally not good/safe shop practice.

Ya, actually my mom was from Thailand and when she was in college, this one guy, a really stupid senior, was using the grinder and something got stuck inside of it, so he stuck his hand inside of the grinder :ahh: , *with the cord still plugged into the wall :ahh: * and took the thing out that was inside jamming it, and so it started to spin again...And well...finger stuck inside grinder...i think you know what would happen...3 fingers :ahh: ...so ya...just a warning. But always try to be safe when working with power tools. No one on our team has lost a finger or done anything like that, but I'm still precautious around power tools because of that story my mom told me.

The dust dremels kick up is nasty. I was dremelling about two days ago and I still have bits of aluminum and bits of dremel bits stuck in the back of my throat... It is not a fun experience. I recommend wearing a dust mask or a resperator (like the kind one would use for painting). It just makes life... better.

Not exactly the same, Andrew Rudolph... We are going for a bit more of a significant change.

Using the grinder would suggest that they are modifying the metal part of the wheels, not the rubber/plastic(?) rollers.
