Polishing nonwoven wheel for buffers
Ignoramus25445
in its ability to polish metal objects. It is some sort of a nonwoven,
maybe nylon wheel. It is almost completely worn, however, and has no
markings left. Does anyone know what sorts of wheels can be purchased
as a replacement? Maybe 3M EXL wheels, as it seems to be.

Yes, I think that they should be grey scotchbrite wheels, too.

Scotchbrite 7S Fine Light Deburring wheel is good for general purpose
polishing. 8S and 9S are OK, too, just a bit harder.
McMaster p/n 46575A73 is probably a 7S, which would make the next two
in the catalog 8S and 9S.

I think you want a "Hard Felt Wheel", a jewelry supply or about $20 on EBay.

What I want, is the exact same wheel I have now, except new and not
completely worn like mine. The wheel works almost like a miracle.

I use them. There great
there usually 6in dia 1in thick with a 1in hole .
then an arbour adapter to fit your grinder spindle.
there made of compressed scotchbrite by 3M which is a 3M product.
there are several grades of hardness , the medium soft works better,
also the grit size will be different as well as the grit type.
The cheaper types use aluminium oxide the best cutting is the silicon
carbide fine.
you need to get in touch with or look up 3m products to get vthe right
one thats the same as you have.
good luck.

There must be some mistake - that item is $67.73. Surely, an 8" x 1"
polishing wheel CAN'T be that much?
And what's with the 3" arbor hole that it has? How do you mount a wheel
with a 3" hole? OK, OK, I know ... you make an adapter. But why should
you have to, why doesn't it come with some reasonably sized hole?

Bob, you need to try a wheel like this. Then you will realize that
$67.73 is a bargain price for what you get. It does an incredible job
at polishing.

That's what they cost. But if you're careful about how you present
sharp edges to the wheel they last a very long time. When I was in the
marine hardware fab business I ran 12" x 3" wide wheels on a large
polishing stand. Even with heavy use I don't think we used more than a
couple or three wheels a year.

3M makes die cast adapters, they're below the wheels on the McMaster
page, and it wouldn't be difficult to make them yourself. That last 3"
of diameter isn't very useful on an 8" buffer, and as you note, the
wheels are expensive.

got one I paid maybe $35.- from sbbolts.com
--One trick I learned early on that makes 'em last a little longer:
if you're deburring a corner on a plate don't present the edge to the wheel
horizontally; do it closer to vertical; dunno why but it works. You may
groove the wheel but at least you'll still have most of the larger diameter
left behind, so to speak.

A typical Scotchbright wheel costs $45

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.
This is despite the thread you are in having not mentioned
race or sexual preference in any way that is relevant to
the subject." Grey Ghost

I actually bought that wheel from McMaster. It turned out to be Norton
Bear-Tex wheel, not 3M. It has the same exact feel as the old wheel
(which, IIRC, was not marked as 3M either) and it works amazingly well
at polishing things, being a bigger diameter. I just polished a 3/4"
by 3" cylinder in about 1-2 minutes, just to try it. I am very happy
with this wheel.
On my 3/4 HP Baldor grinder, now, I have this Bear-Tex wheel for
polishing, and a 3M DBX wheel for deburring.
I am sure that I will make my money back many times over, by polishing
things before putting them on ebay.
