How NOT to mount a wire wheel (or grinding wheel...)

[Outlawmws]

So I was dismounting a combined/stacked wire wheel and grinding stone off a small grinder I picked up free on Saturday.

I hadn't really paid a lot of attention to it, until I went to unscrew the "nut" and discovered it was more than a nut...

It was the remnant of a ****** screw on wire wheel for portable grinder!

I was also wondering why stack a 6" wire wheel on a 6" stone?

Then I realized the 6" wire wheel had NOTHING keeping it centered!

The stone thank goodness WAS centered...

But the "backing plate" for the stone was a std 1/2" cut washer!

PO = Darwin award candidate!

Did you go back and try to get your money back??

so was this on a bench grinder i'm assuming or a hand grinder and really a Darwin award winner?

That had to be a teeth-chattering experience when that grinder was turned on.

 

[Outlawmws]

Bench grinder DIF, and Hmm... how to get the money I didn't spend back for it...

You know, I gave it a quick test spin up to make sure the motor worked and it wasn't that far out of balance! I was doubly surprised the wire wheel was just eyeballed!

Holy hell. That's Mickey duck right there.

i knew you got it for Free, but my o my the creativeness of some people's kids.

on your side you have a working grinder and 2 good wheels and another one that looks like it might skip on a pond nicely.

glad you got that instead of a young guy that didn't know what he had that might have used it.

 

[Outlawmws]

Well, so much for using the motor for anything; after using SG to get some of the gunked paint of the label: Made in China... (I was hoping for at least Taiwan)

After being so poorly mounted, if I owned that stone, it would have a date with a large hammer, then the trash can.

Holy craptastic!! I'm sure Outlaw won't be throwing it away, just not using it personally.

I guess that's why these are important safety instructions----

It is amazing what dangerous things people do and get away with.

I read threads that warn/caution people of potentialy dangerous shop pratices and quite often there's 1 or more posters who 'poo poo' the advice and say something like "I've been doing it one way or another for x number of years and never had a problem."

I look at it this way - yes, you can close your eyes and run across the street at rush hour and not get hit, but how many times will you be so lucky?

Thanks for posting. We all need to be safe.

I'd bet the guy didn't give a second thought to it being a dangerous setup (Darwin Award then as Outlaw mentioned).

RPM's have a way of making bad ideas worse.

Sure, it's a hokey way to mount the wheel but I'd bet a paycheck it wasn't coming off without a fight. It's really just an ugly hex hat nut. They actually sell similar nuts, albeit smaller and without crimped wires.

What's really hack-ish and dangerous is that it wasn't mounted with something to keep it centered. That allows the work-piece to be pulled or bitten unlike a centered/balanced wheel. However, Outlaw even said this one didn't vibrate badly... so really, we're just looking at a lucky hack.

The user may have a nice scar to show for it but I don't think this set-up was killing anyone. Now, that doesn't say much for the person that set this up... what other contraptions has this person worked on?

I know a guy that thinks stuff like this is perfectly acceptable. I worked with him. He was notorious for cutting access panels in the bodies of BRAND NEW 15-20 thousand dollar commercial washers because it was too hard for him to change valves in the future. This very well could be a grinder from his shop. Actually, I'm not sure, since it was had for free, this guy thinks his "inventions" are priceless.

I've seen too many hack jobs, Most likely done a few my self, Now if I can't do it right I just don't do it...

 

[Outlawmws]

Brent, it actually came off quite easily.

The other part of the hack job was the cut washer for a backing plate... WAY to small and likely to fracture the stone

 

[bczygan]

OMG!

I'll be right back..........gotta go change some things on my grinders......

With all of those warnings, I wonder why they didn't state the max speed.

 

[Outlawmws]

It's probably on the other side.

Wire wheels, my 5 hp table saw and my 8" joiner is the most respected machines in my shop, I have been bitten by all of them. I buy nothing but the best wire wheel, saw blade and align my joiner blades as best as I can.

 

[Outlawmws]

So KM; how high can you count?

I do not understand, my grand kids count to me all the time. i guess maybe a 100.

 

[Fretters]

On the fingers I'm guessing?

A novel way of mounting a wheel was that

 

[Outlawmws]

So the grinder motor ain't staying.

I did get some more paint off the label (and the label off the motor) It's a sears, (possibly craftsman) grinder motor. It's small, 5" dia case, 8-1/2" end to end on the case, shafts stick out from there, Probably 1725 RPM. I thought it might fit in a Med Flat rate box, but it won't. Large FR it will.

So if anyone wants the thing, they can have it for the cost of shipping (FR; probably $16)
