I've not done this yet with horn, but I have with many other materials.
Polishing is simply the art of taking big scratches and making them
into smaller scratches. Then make those smaller, and so on.
For this, I would sand smooth. Very smooth - at least 600 grit
sandpaper. Then, if you have a bench grinder or other motor that will
take a buffing wheel, start with triple-E polishing grit and move up
to white diamond. Alternately, you could probably use a car polish
(I tend to like Maguires), first heave cut and then fine. Only then
would it be suitable to finish up with a wax, probably carnauba.
Hope that helps.

Get a buffer wheel. Either on a bench grinder or on a drill. Use a cloth one.
Even Drimmel Tools have them.
Also go to hobby shops that specialize in rock polishing. The techniques are
similar.
BTW folks, don't any of you have hobbies like RC planes or rock
collecting/polishing or such? Or even wood working?
Get a hobby and learn some life skills....
Others here have provided suggestions for polishing. Knowing nothing of
this art myself, I have nothing to add or subtract in that department.
But might I inquire what your purpose is here? You can purchase a ready
made and polished shofar for far less than the cost and bother of doing
it yourself. But I imagine your desire is to have a self made product
rather than a commercial one. If so, why would you wish to polish it so
that it will look just like the commerical ones? I would think it
prefferable to retain it in its natural finish so that your efforts are
recognisable, not camoflaged.
Is this shofar prepared for decorative purposes or for ritual purposes?
If the latter, then before going to further trouble and expense, one of
our authorities on rabbinic zoology might enlighten us regarding the
anatomy of the kudu horn, and whether such horn meets the requirements
for shofar. Not all mammalian horns do, and in fact many do not.

eagerly awaiting the sounding of the shofar that heralds Mashiah, as
well as the lifting of the non-shofar horn of King David (wuqarno tarum
biyeshuathekha, wayarem qeren meshiho). Good writing and sealing to all.
FWIW, it's Dremel... And a Dremel tool would be a bit undersized for a
42" shofar, nu?

Lapidary equipment would be singularly unsuited for polishing organic

Get a hobby and learn some life skills??? All I can say is that you
know very little about me. I asked about polishing the shofar because
I haven't done one before and don't want to screw it up out of
ignorance. Meanwhile, do I have hobbies? Let me see... I've collected
and restored literally hundreds of antique Kodak cameras. I do
woodworking and have made both furniture and kitchen cabinets in my own
house, as well as numerous smaller gift items. I used to build model
cars and airplanes. I repair and restore antique bicycles, as well as
maintaining my road, track and mountain bicycles and my Kawasaki
Drifter motorcycle. I've restored three 1958 Chevys and two classic
boats over the years. I have a library that's busting out at the seams.
I built my own computers and wired the house for a home network, as
well as redoing much of the other wiring and plumbing. I designed and
built the patio deck and furniture for the local shul president. More
recently, I installed a hardwood parquet floor in the kitchen and built
new steps for the patio door, rebuilt the fencing and gates when we got
a new dog, and maintain a garden full of blooming rose bushes. Two
years ago, I rebuilt and refinished my piano, including installing new
pedals and bridal straps and retopped the keys. I play several
woodwinds as well, and sing with the local choral society. I could go
on and on, but I think I've made my point. Asking for advice on a
particular project isn't an admission of total ineptness. It's a
recognition from experience that the materials which work well with one
thing don't automatically carry over to another. It's the same reason
that I don't use the same jeweler's rouge for polishing stainless steel
as I used when I refinished the Torah finials for my shul. Using the
wrong stuff can screw things up royally. Any more questions?
Eliyahu
Update: I have made inquiry myself. Yes, the kudu antelope has horns
that do meet the requirements for a shofar, and in fact these horns are
prefferred in many Yemenite communities.
I still stand by my recommendation that you leave the shofar with its
natural finish. Why would you want to give it a high gloss finish that
makes it look cheap and commercial? Papa was a shohet for many years,
and he prepared a good many shofroth, several of which are still in my
possession. All are from rams or ewes, non from kudus. None is polished
glossy.

There are grits that are more course. And the basic polishing wheel would work
well.

Then why ask us? You have the skills and the knowledge already (of which most
American Jews seem to lack). You would be far better then to ask those who are
experienced in this material which I doubt that you would find here.
Frankly I would use wood working or rock polishing tools myself. I would adapt
them to the job at hand. It is finding the right level of coarseness in the
polishing material.
From his reply (sometimes it works to insult people in order to get them tell
more) to me, he has the skills and likes to work with his hands.

If he knows how to polish wood, why would anyone assume the same
techniques would necessarily work with animal horn? There's a lot of
ranged experience in this group, someone may have had a better technique.
Unfortunately, it appears not, but that doesn't make it wrong for him
to have asked.

Why? Is there something wrong with wishing to make an item with one's
own hands, even if that item can be readily purchased from a store? I
don't think he needs to justify himself to anyone at all.
Incidentally, would a nail buffer work? Nails and horns are not too
terribly dissimilar.

their own vegetables. A side benefit to it is that it makes us less
fearful of a breakdown in society or in the distribution system for
consumer goods. Despite the stereotype of American Jews being
mechanically inept, I've always enjoyed building and making things
myself.

It probably would work, but the horn is a bit large for that approach,
being, as I mentioned, 42 inches long. Imagine using the nail buffer to
polish your entire left hand and arm... :-)

I saw a few references on Google to horn polishing, it looks like it has a
wider scope than just shofars.
I had a horn that i tried to turn into a shofar once years ago, didn't
have much success, but I learned that you have to be careful with power
tools because of burning -- definitely a concern at the drilling and
polishing steps. Old-fashioned elbow grease might be your best bet.
I saw on one shofar site that they actually straighten the horns first,
drill them, then re-spiral them using heat to soften them up.

I'm not sure, and now I can't find the site again, but I found it in the
first place by googling "kudu horn." Isn't the tip solid, though? The horn
I had, and also per one of these sites, the first few inches (at the
pointy end) were solid and had to be drilled.

Reminds me of a joke I read many years ago:
Two women neighbors are talking over the fence. One says:
You know, my three apple trees gave so much fruit this year, that I
have enough apples stored away for the whole winter. I've made aplle
jelly and apple fruit compote and applesauce, and I've a freezer full
of apple pies. I've made baked apples and apple fruit salad which I've
put in jars for the winter, and candy apples for Halloween and candied
apple peel. So many apples! If you were me, what would you do next?
Second neighbor: I'd chop down the trees.

Well, true, but you might look for sandpaper/chamois cloth that is
similar to that used in nail buffers - a similar grit size and all
that.
Good luck with it, btw; sounds like a cool project. Will you post a
picture when it's done?

ROTFLOL! Josh, where do you _find_ these things? And who puts them
out? There were _many_ actors in that video.
> Enjoy :-)
I surely did, thanks.
This isn't the best group to ask this question. If I were you I post the
question to a rec.crafts. newsgroup, maybe rec.crafts.jewelry or
rec.crafts.misc.
I guess that I am used to the over educated, don't get your hands dirty, Jewish
community that we have a long the North Shore of Chicago. Frankly I am
surprised to find any Jew who knows how work with his hands.
As to horn vs. other material, I guess I am more adventurous. I would have just
tried a very light grit or fine polishing wheel. But then I tend to adapt
techniques and tools all the time. I like that level of experimentation and
creativity.
I once asked why we no longer have Jewish working class folks in the US. Some
wit here posted that Jews finally figured out that it was better to let the
goyim do all the work.
I guess that I am surprised to find, in this day of everyone with a masters
degree (and an avoidance of getting one's hands dirty), that we have any Jews
interested in craftsmanship and hand work.
That's what makes SCJM nice; there's a broad range of people here.
Personally, I'd do more with my hands if I didn't ruin most of what I
touched. I've made a few clocks that have come out well, though.

We don't know how much he paid for the raw horn to say if he should be
experimenting on it.... :-)

Several of the regulars on news:rec.crafts.jewelry
seem to be very helpful. Jewelers polish many materials,
including horn. It's not the commonest material but
I've seen it.
I'm recalling a little rotating drum a friend had
the would polish toy railroad trim. That would be
much to small, but the principle would seem to apply,
except you would need a big rotating tub with
grit in it. How you would make that I'm not sure.
You've gotta be kidding me (particularly in Chicago). Most of my shul is
contractors, and I know a whole bunch of other frum handymen,
electricians, etc...

Oh? I'm surprised there is such a stereotype. My father remodeled an
entire house on his own - new floors, new moldings, built-in
bookshelves, tile, everything. I've been helping him with carpentry
and home repair projects ever since I was a little child. The first
real estate I ever bought was a "fixer-upper" - and that's a euphemism.
I did all the work on it myself (with a bit of help from friends).
And I've got a master's degree and my father has a Ph.D.
Incidentally, I can also do basic machine-shop metal work - that was
part of the mechanical engineering degree. I got the highest grade in
my machine shop class.
LM
Actually that is very encouraging. I am so used to every not knowing
how to do anything practical. Now that we have all these shows about
remodeling homes and such, I would expect to see more interest.
I have lived around too many college professors who have "Attitudes"
about the working class. I do think that too many in the US have
forgotten the pride of craft work (as in labor trades).
Ken, you once said which House of Prayer you attended. Your
congregation is more downtown, isn't it?
I would agree with you that we would see more Sephardic individuals who
have training in the crafts. Much of that is not present as you go up
the North Shore, however.
And then there are those who have "Attitudes" about college
professors... some of us actually can do basic home improvements and
such, you know...

Nope. It's Rabbi Raccah's shul. You never told me where you are, except
that you go to sephardic shuls. I'd like to meet you sometime if I can.
