Default coffee grounds?

I passed by the other day and caught mention of coffee grounds as a
filler..Someone pls explain the uses application methods..I'm intrigued by
this as I am about every innovation I see, along with the ingenius thought
processes wood turners use in solving a myriad of problems..Here to

Grind coffee beans very fine in a grinder. Mix in to clear epoxy (I use
the 5 minute variety). If you are using the coffee to color the epoxy,
only a little is required. I have also heard that if you incease the
coffee to epoxy ratio you can use it to fill in bark exclusions
although I haven't tried that yet.

The primary use of coffee is to make a good cuppa-coffee! Do that FIRST.
Then dry the coffee grounds and mix with some 5 minute epoxy. Ratios have
not proven to be critical in my experience. Fill hole. wait 6 minutes. In
Canada we add one minute to 5 minute epoxy because we are a metric
nation..... Turn as per normal.

I'd go to the hobby shop and find the micro glass balls used in airplane and
boat building. They won't decay or smell of coffee at the wrong time.

Hi Rick

I use coffee grounds occasionally, like in a case of a knot that is
darker than the surrounding wood , or with some bark inclusion that has
gaps, the color of the coffee ground chunks and bark are very similar
usually, doing that with paint or coloring dye is very hard, and saw
dust is not the same very often, though I do use that also if I can.

I use coffee ground that has been used, I dry it in the microwave oven,
the reason for using used coffee is that coffee has an oil in it and
when used most of that is gone ( OK and I'm a Dutchman ).

I have tried epoxy mixed, but don't like the outcome, (the color and
texture), so now I use the coffee ground with CA glue only, I pack the
coffee ground tightly by pressing it in the cavity and then slowly flood
the CA glue in, I use thin CA mostly, if the hole is big than I will get
a chunk of wood that almost fills the hole and then fill the remaining
gaps with the coffee ground and then use the CA.

I also use the CA glue with brass or copper filings or dust, the color
is a lot more real than when mixed with epoxy, for the simple reason
that the filled hole is all metal with only the openings between the
metal parts being glue, plus I don't have to wait till tomorrow for the
glue to cure.

Have fun and take care

Like Leo, I use coffee grounds with CA glue. Have filled really big
voids--one about 2.5" by 1" and it looked great. It became the main
feature of the vase. I put a piece of tape on the back side of the
hole, and just alternated grounds, CA, and accelerator until I filled
the void. I've used both used grounds and new--doesn't seem to make a
difference.

Group:

Just a quick warning, take it for what it is worth. Note that the
ingredients of CA contain (prominently!) cyanoacrylate.

We have a bona fide research chemist in our group, and he has warned us
about using key filings or any other kind of non ferrous metals with
CA. According to him, the smoke that come off the metal in reaction to
being mixed/exposed to the glue is actually the molecules of cyanide
being released, and therefore you have a mild form of cyanide gas!

Just a heads up... I know there are those here that will intentionally
huff the smoke/fumes to be contrary and will come back here to announce
they are not dead.

But remember you basic chemistry classes... it makes sense! Even if it
doesn't, WTF is that smoke anyway? Why take a chance?

Just last year I went to a demo by a well known turner that claims that
one of the folks in his club can no longer turn as he was a fan of
using CA as finish (flood the surface, sand off and polish). After
about a month in the hospital they finally found out two things:

- Permanent nerve damage (tremors)
- Condition was consistent with cyanide poisoning

The conclusion was that as an avid turner, he finally hit his toxicity
point after about three years of that particular finish. He can no
longer turn.

I used to use a Dustfoe 88 mask in the shop. A fairly good amount of dust
got through, but I thought anything more would be too hard to breathe
through. I got a headache when doing some extended finishing in the
finishing room in a different building, so I bought a respirator mask for
$20 rated for paints & varnishes. Amazingly, you can't smell the finish at
all through the mask and it is not that hard for me to breathe through. I
decided to try the same mask in my shop for sanding and when applying CA and
it works great. One advantage of the twin cartridge respirator is that I
actually have better field of vision down and ahead than with the other
mask. When you sand the CA you should use a fan to clear the immediate air.
If you are too close and sand too hard you can feel the sting of CA in your
eyes.

But some people are tough enough that they don't need to use safety
equipment with toxic substances (until their liver can handle no more and
they get cancer, etc).

Hi Robert

Bob did you actually see any mentioning of cyanide gas in any of those
research papers, all I see is possible dermatitis etc., and gluing skin
together, but nowhere is there any mentioning of cyanide gas mild or
otherwise.

Rick.

I't like to say thanks for raising the issue. I'd never heard of that. I
just tried it last night on my third bowl. I reground some spent grinds (to
reduce them to powder) and mixed them up with some epoxy.

The result was a consistent dark chocolate filler with a little more body
than straight epoxy.

Turning off the excess smelled faintly of coffee too :-)

Cheers

Steve

together, but nowhere is there any mentioning of cyanide gas mild or

Yes, I actually saw in the paper that it was mentioned as HCN. It has
been proven that the cured monomers still give off gases that are of
concern:

http://www.niih.go.jp/en/indu_hel/2004/pdf/42-2-14.pdf

However, this is not the the issue that is of greatest concern. I am
still thinking that the best reason to beware is the fact it is being
sanded/ground into microparticles and inhaled. If you breathe in the
particulates around your dust mask, this material will be IN your
lungs, leaching out small amounts of toxins over a period of time.
Please read the "conclusions" at the of the paper.

And, if as some have pointed out, the "smoke" is nothing more than
vaporized super glue which is easily inhaled, in particle size small to
get into your bloodstream. Good luck with that... I have seen no
research on how that is removed.

You can see more opinions on this topic in a newer thread where someone
asked about using CA for a finish. Also, a ton of info was available
in a Google search in less than five minutes.

I think it is most important to realize that ALL of the research
performed is on using CA as, well, an adhesive for which we all use
it from time to time. These are tests that are studying the free
gasses given off by the CA while it is hardening. They are not studies
of what happens if you sand it, mix it with other chemicals (say as in
the solvents found in your buffing wheels) or any other conditions that
exist when we as turnners use it.

My post was meant as a caution. That's all. If it helps one person be
more thoughtful or careful when using any of the stuff we take for
granted on a day to day basis, mission accomplished. And really, in my
mind, I see no reason to take a chance at any of these things,
especially if some have taken the time, money and effort to put into
quality research that raises concerns.

On the other thread, I am thinking one of the participants is going to
drink some CA to show how unafraid he is of the stuff...

One can only hope...

My earlier didn't make it through my ISP, but putting some bark through a
burr mill makes a great filler that looks absolutely natural in a bark
pocket. You can grind coarse or fine, and filling below the line and
sprinkling the rest on top of accelerated CA gives you something that takes
a finish almost like the real stuff. With epoxy or CA solid, you have to
"tooth" it to get a varnish to stick and equalize the appearance.

Big cracks are stuffed with bigger unground chunks, and look pretty good as
well.

So will WOOD. Maybe we should all stop turning dangerous substances such as
wood and instead start turning ice or something else known to be chemically
inert in the human body just in case we accidentally inhale a little bit of
dust.

Hi George

Yes that works real well also, I don't have a burr mill, and use the end
of a stanley knife blade on a dremel arbor, load some small chunks in a
glass jar end shake the dremel/jar combo until I have enough small, fine
and coarse pieces, I think your burr mill would do a nicer job but this
works also.
As the question was about the coffee ground, I didn't include this way
of improving things, and yes I think in some cases this (bark) does a
much nicer job.

I'm not sure, but a Burr Mill might be a coffee grinder?
Bought one for the RV last week for about $15...
It seems like it would work well, except that your only control of course/fine
is how long you run the grinder..

Could be. Could also be a Peppermill. The space between the burred cone
and the burred taper determines the size of the final pieces.

That's a blade grinder. You can also get coffee grinders that use a burr.
With those you adjust the grind by the position of the burr. They're
harder to find and more expensive.

Point of fact, Solid glass micro-spheres are a b*tch to sand. However,
hollow glass micro-balloons sand extremely well. They are the resin filler
in the 'light' autobody fillers.

Other good epoxy fillers are talc (easy to sand, filler used in most
autobody fillers), phenolic micro-balloons (purplish-brown in color),
mini-fibers (white polyester), Cab-O-Sil (fumed silica thickener). I've
also used ground walnut shells, and calcium carbonate (ground marble).

What you are describing sounds like a 'whirly blade' grinder. A burr
grinder has a cutter that looks just like the burrs for a Dremel, or air
grinder. Want more info? visit alt.coffee Dan

The easy tactic is to buy a pound of el cheapo coffee beans at the grocery
store and use their grinder set to 'espresso' for extra fine grounds.

In plastic resin systems, a filler is anything that replaces the resin.
Usually done to alter the physical qualities of the resulting composite, or
to reduce cost. They are usually in the form of small particles, i.e.
ground coffee.

A reinforcement is something added to increase tensile strength or flex
modulus. Most of these are fibrous, as in wood fiber, glass fiber, carbon
fiber, etc.

Once encapsulated by the epoxy the coffee smell will be negligible.

Sounds a little odd to me, too- he can't even turn with a good
respirator? Granted, I don't know all that much about it, but I'd
think that as long as it isn't getting in your nose/lungs, it'd
probably be a non issue. Some stuff will cause dematitus, but all that
needs is some lotion.

Hi Mac

One grinder should do just fine, just borrow the "gourmet" one, you
could even try some new wave coffee/red oak taste or java/walnut, there
might be some money in all that ground bark G

Have fun and take care

I don't think so, Leo.. I might have to drink some of it too...

That's a blade grinder. You can also get coffee grinders that use a burr.
With those you adjust the grind by the position of the burr. They're
harder to find and more expensive.


Thanks, John... the whole grinder thing makes more sense to me now...
I'll have to look into a couple of those (1 for wife, 1 for shop) since my wife
is a coffee "gourmet" and I'm a "red can" sorta guy.. *g*

but the down side of those, if they're the type that my wife bought, is

that
they don't sand well...


Point of fact, Solid glass micro-spheres are a b*tch to sand. However,
hollow glass micro-balloons sand extremely well. They are the resin filler
in the 'light' autobody fillers.

Other good epoxy fillers are talc (easy to sand, filler used in most
autobody fillers), phenolic micro-balloons (purplish-brown in color),
mini-fibers (white polyester), Cab-O-Sil (fumed silica thickener). I've
also used ground walnut shells, and calcium carbonate (ground marble).

the problem that I had with the ones that she bought (probably very inexpensive)
is that they were colored... gold, silver, red, couple of browns, etc.... and
the color was only on the surface..

They looked interesting in the crack until you did a little sanding, then they
were just a dull gray..

The conclusion was that as an avid turner, he finally hit his toxicity

Waitasec, He can no longer turn, or no longer finish with CA? HUGE
difference. Dan


If he can no longer turn then sounds like it was the wood that got him and
not the CA. Wonder what he was turning.

Subject: coffee grounds?

Robert! I resent this. Posting this twice in two different threads,
on the
same day, creating two discussions is not only poor protocol, but falls

under MY definition of 'mother henning.' cluck, cluck,
Robert.

Dan:

If you are going to whine, get it right. I posted similar information
to two threads AND IT WAS NOTED IN THE SECOND THREAD. I didn't mean to
sneak up on you with putting it in writing.

I DID NOT start either discussion. You can find out who started the
thread by looking at the original post, you know, the first one in the
thread. That is not always reliable, but it is a great place to start
before whining.

As far as the CA discourse goes, posting that info here, as well as the
subsequent links was like trying to teach a monkey how to whistle with
a moutful of crackers.

It is the sanded particulates people. They got in his system. Maybe
he wasn't wearing adequate protection, maybe he was allergic to the
solid glue PARTICULATES FROM SANDING HE INHALED.

I never said he had a ****ing skin rash, or had a reaction because he
got it on his hands, fingers, mouth, or that he took it intravenously,
or that he drank some. I use CA every time I turn - no ill effects.
But I do not sand all day on whole projects finished with it, either.

My post was meant as a simple warning. However, I would now invite all
here that are sure they have no risk exposure with this product to
prove to me exactly how wrong I am and drink some, snort some, eat
some, screw some, whatever you want. Just get the particles in your
bloodstream some way. Don't just get some on you, or sand an ornament
or pen or two and think that will do it.

Please post pictures, though. Like you guys, I now need proof; written
stuff ain't gonna do it. I'm gonna drive up to Austin myself and call
that old sonavabitch out on this since he was obviously lying to his
turning club when he tearfully quit. What a sorry ass. I wish he had
contacted you guys before he went to his neurologists. Think of the
money he could have saved, and then all the great advice....

The Drs. : Well, he INHALED the particles of dried CA. We found them
in our tests... in absence of other debris in the lungs that would
cause neurological problems, we think it is the CA we found. Our
research has shown evidence that leads us to this conclusion. We are
advising that he give up his woodworking because of the damage to his
lungs.

Group: No F'n way. Give him some lotion and send him home. I use
that stuff all the time... it hasn't happened to me yet. And if I
don't know about it, it probably doesn't exist. Haven't you guys ever
seen CSI? Hell, they use it all the time on three different shows and
they are all back next season!! What are they trying to pull here?
And give up woodworking as a safety precaution? What kind of left wing
bull**** is that?

++++++++++++++++++

Hey guys... maybe with some work you can pull in a good conspiracy,
too!

And Dan, back to your barnyard. Cluck my ass.

Robert
