I'm used to Naval Jelly and wire brushes / drill attachments for small rust
issues, but how does one deal with bigger areas?
I've never owned a bench grinder, and recently got an older used unit complete
with pedestal stand. The motor runs smoothly and I'm pleased at having spent
a whopping forty bucks for a tool that will be of some use to me.
But the pedestal base is quite rusty, with the underside of the base
especially bad. I'd say this would be described as severely rusty.
Are there any established techniques for dealing with something that is
realistically too big to handle with normal techniques? I know I could say
that it's in a dry environment now and probably will outlast me with doing
nothing, but I'd still like to get it reasonably cleaned up.
All of this media-blasting and angle-grinding seems a bit over-the-top for
a grinder stand that will be used in a dry environment.
If it were me, I'd just use 50-grit emery cloth (NOT sandpaper!) to smooth
out the rust by hand, then I'd rattle-can the stand with Tremclad or other
rust paint. Done.
The admonition to use eye-protection is a wise one.
A guy I knew years ago was using a chisel without wearing goggles. He ended
up with a chip in his eye and had to go to emergency.
When removing the chip, the guy had to be AWAKE, EYES OPEN. The doctor
said, "Whatever you do, don't move your eyes or blink". So my friend was
forced to watch as the doctor dug around in the white of his eye to remove
Can you imagine? Can you?

I had a friend who used a framing hammer on cut masonry nails, sans eye
protection. After which, he had ten similar operations over the next ten days
to put his eye back together. The doctor was among the best and he didn't
lose the eye but it was a close one.
The only thing that has kept me from losing an eye is the fact that I've
been wearing eyeglasses since I was six years old. When I first
had the eyeglasses put on me, I looked around and exclaimed, "Wow,
that's where all that noise is coming from!" ^_^
I'm actually inclined to believe that in the long run, people who need
glasses will prevail in the gene pool because it's an adaptation that
confers a certain level of eye protection. I've hear things "ding" off my
glasses that otherwise might have taken out an eye.
I have the worst vision among me and my eight siblings, we're all myopic
and I believe mine is because I was a drug(nicotine) baby
back when people didn't know any better than to expose a fetus or
infant to that horrid alkaloidal insecticide. I smoked for 9 months
then I was born and because of my immersion in that amnio-toxin, I'm
deathly allergic to tobacco smoke. It's like tear gas to me. o_O
Yeah, I had it happen to me with a small piece of debris when using an
angle grinder last year - I had safety glasses on, but somehow whatever-
is-was still managed to get around them and into my eye.
At the hospital I was expecting some sort of high-tech solution, but they
wheeled out this ancient light / magnifying device, put some numbing
drops in my eye, and then used a broken piece of wooden stick to dig the
Apparently eyes heal really fast. I had some antibiotics for a couple of
days, and it was all back to normal within four or five.
Luckily it was a stone or a piece of paint or something of that nature -
apparently metal's worse because it can rust prior to removal and cause
all sorts of problems.
I can concur that safety glasses are only a partial solution when using an
abrasive or wire-wound tool (unless you are using chem-lab style glasses).
The solution I use is to wear my normal safety glasses underneath a
full-face polycarbonate shield. After having a few close calls wearing only
safety glasses, this is the only way I fly.
Wise choice. Grinders (and most power tools :o)scare me, having nursed
a whole lot of different kinds of injuries. Read about a guy in Florida
a couple of years ago using a grinding wheel; wheel broke, fragment flew
up and hit him in the neck...he bled to death. Freakish.
I was at my doctor's clinic, waiting my turn. In comes this very tall big
man with more bleeding bandages on than I have seen any human being have.
The nurse asked him what happened. "Tangled with a grinder" was all he
said. In about five minutes, the nurse came out and said it would be a good
while before they could see me, and maybe I should come back the next day.
Hand grinders are the nastiest tool in the box, IMHO, after working with
them for 38 years now.
Often use stain that shows up under UV light to spot corneal abrasions.
The "broken stick" was probably a cotton-tip applicator, the cotton
being the business end.
An abrasion can start "healing" to the lining of the eyelid. Ouch!
Rust can cause staining of the cornea, so needs prompt attention.
I took care of a guy who turned on his lathe with allen wrench in
place...the lathe turned, hung up, and then let the allen wrench fly.
Busted the guy's safety glasses....there was blood coming from under his
lid when he got to my office, so shipped him out pronto to the ER. He
had glass in his eye, small abrasion to the inside of his lid and no
injury to the eye itself. Lucky as heck!
Any foreign body needs prompt attention. If it can't be rinsed out
quickly, the eye should be covered until one gets to the doctor; patch
keeps the eye from moving and causing further abrasion.
