Default Noisy T&C grinder head

I have a particular tool and cutter grinder. Its head is noisy, in
fact, its noise resembles the sound of a rotary siren (though not as
loud). Would you say that the most likely cause of it is bad bearings?

As per usual iggy leaves out the name of the tool and cutter grinder he's talking about.

Has iggy made any effort to use a dial indicator to check it for run out?

Has iggy made any effort to spin it and feel for flat or hard spots?

Does anyone else besides myself get sick and tired of this cocksucker not providing enough information over and over for years on end leading many of us on wild goose chases.

Lets all keep jumping to provide help to this lazy, non-mechanical, inconsiderate, **** bag who can't be bothered to provide basic information or make any effort to figure out anything for himself.

Jon, one cannot be led on a wild goose chase unless one is _willing_ to
be led.

Ig may not ask the questions you approve of, but he also isn't demanding
that you, personally, spend your time to answer them. You _could_ just
ignore them... no?

You put more energy into complaining about them than many legitimate
answerers put into their answers!

That last question was one of those "well... DUH!" ones to me, too. But
at least when someone gives Ig an answer, he considers it, might use it,
tries to understand it. (FWIW, he GIVES answers to folks, too... about
higher math. No... polar trigonometry is not higher math. I mean
h.i.g.h.e.r. math...)

Ig's not like that dope who keeps coming back around asking things like
how to wire a welding circuit using steel wool for wiring, or why, just
because a drill bit is right-handed, couldn't he go ahead and use it in a
left-hand direction anyway!

So... Jon (seriously), if you don't like his questions, why burn so many
calories on telling him and us why you won't answer them? Just ignore
him!

I have spent over 20 years working in CNC machine shops. Mark Wieber has provided nothing but lies and lame excuses about why he never has worked as a machinist.

The **** hole Mark Wieber lives in, his inability to keep medical insurance, his constant excuses for not paying his bills, his reliance on drinking brominated vegetable oil 24/7 - 365, the number of dogs that have died from his neglect, his many phony death treats including his claim that he had something to do with Cliff Huprich's death, etc. show exactly who and what Mark Wieber truly is.

What I object to is the tone that Mark Wieber's clique of idiots now set in this newsgroup. It wasn't always this way until Wieber destroyed this newsgroup with his crossposting.

The focus of this newsgroup has shifted away from learning to be mechanical and learning how to think on your own to who can do the best job of getting on their knees and sucking Wieber's cock.

If the motor is tied directly to the spindle..remove the motor and
run. If you still hear the squealing..check the sheetmetal around the
fan and see if it got dented. If it still squeals...hold a long screw
driver to the bearing areas on each end and put the screw driver
handle in your ear for a stethescope.

If it comes from the spindle...pull the bearings AND MAKE A DRAWING of
it being disassembled (or take photos as you remove each part) and
order and install new bearings

Um... why not just use the _almost_new_ Snap-On Mechanic's Stethoscope he
bought for $2.00?

Seriously... It must've been over 40 years ago that I learned the value
of having an _actual_ professional stethoscope with interchangable probe
tips in the kit.

Especially for machines with big tin bodies around them, they're
invaluable for finding where the real noise is coming from.

Further, unless you stick it into a running fan, or light it on fire, a
good stethoscope is a one-time purchase.

There are inexpensive electronic versions with contact microphones, too.
I dunno if they'd last forever like mechanical ones do, but if you keep
the batteries stored separate from the tool, one should last many
decades.

Good point.

I bought a stethescope a few years ago for just this need..and found
out it works very well...but a screw driver works Almost as well and
doesnt need any special care in my tool box.

As an old man who grew up in the shadow of The Great
Depression, I'd use solvent of some kind, and clean
out the old bearings. Regrease them, and see if that
helped. I do think the drawings and photos are
excellent idea.

Stormy, grease (ner oil) never helps a screaming bearing. It might help
deaden the noise for a few minutes, but doesn't aid in the underlying
cause, at all.

True indeed. However...if it was surplus machinery..it probably had a
hard life..and more than likely cleaning and greasing old bearings
will increase the lifespan a small amount..but not really "fix" the
propblem. Shrug...When I fix a clients machine...I avoid putting
bandaids on them..I fix them properly so it has a much much longer
life span.

For a hobby shop..your method will probably be viable.

Is it possible to detach the two, scrape the

Is the tool big enough for zerks, or is it

I tried turning the spindle by hand, and I did feel some un-evenness

So what does that tell you, numb nuts?

The reason you left this information out of your original post is?

Don't bother to answer because I had it right form the get go.

Suggest you get back on your knees iggy where you belong and keep sucking Weiber's cock. Sucking Weiber's cock is what losers like you and Larry Jackass do best.

That's one theory. Second thought, is that
Gunner might have caught a couple volunteer
firemen looking around his back lot, and stuffed
them head first into the grease cap.

Depends on the construction. If a standard 60 Hz motor with belts,
then definitely has to be bearings. If a universal motor or other
direct-drive high speed motor, then it may actually be designed that
way (although annoying). I have an air bearing PCB drill spindle
that can run up to 80K RPM or so. It has a "spurt" hole when the spindle
lines up with a hole in the housing that lets a burst of air out of
the bearings. It definitely sounds like a siren, and also uses a lot of
air.

Depends on the construction. If a standard 60 Hz motor with belts,
then definitely has to be bearings. If a universal motor or other
direct-drive high speed motor, then it may actually be designed that
way (although annoying). I have an air bearing PCB drill spindle
that can run up to 80K RPM or so. It has a "spurt" hole when the spindle
lines up with a hole in the housing that lets a burst of air out of
the bearings. It definitely sounds like a siren, and also uses a lot of
air.

It is a motor plus belt plus spindle.
