Default Is this *real* mahogany

I have what was sold as Honduran mahogany and it looks like it
to me. What is bothersome is that parts of my boards refuse to be
smooth..... I can sand (to 220, which is what I read is the max
useful for mahogany) or scrape as much as I want and still there are
these parts, typically an inch wide and between 6-12 inches long, that
remain fuzzy. They don't "tear out" so much as just look fuzzy. A few
months after finishing them with oil and shellac, those parts look as
if they have sucked up all the finish and some are beginning to
lighten up - a blond streak in brown hair, so to speak.

So, it this the behavior of some wood other than HM? Or is it
sapwood? Or is it my bad finishing technique? ?? ??

Thanx

I have used mahogany for many years and have experienced what you describe
very seldom and never is what is classified as "honduras"mahogany . For that
reason I never use anything but Honduras , that is the only way I can
guarantee quality . Seems to me you have been sold some inferior quality
stuff for honduras prices . You might ask the wood merchant top see his
purchase order, if it was offered to him as honduras then he needs to check
his sources ....mjh

Actually what you have is African Mahogany and it is usually passed off as
Genuine Mahagony
It is a good wood but can be a bear to work with. You will also note it is
darker and can have some black streaks going through it.

Right now due to the Politcal Climate the supply of Honduras is going to Dry
up and Prices are about to sky
rocket if they haven't yet.

Phillipine Mahagony closer color to Honduras, it is a lot softer and is
generally known as cheap ****.

Good Luck,
George

True Honduran Mahogany gets as smooth as buttered silk, like slipping
into the best girlfriend that you ever had.

What you describe is more akin to what goes under the tradename
Philippine Mahogany, which is crankier than the worst wife that you
could ever imagine, twice as hairy, and not really a mahogany at all.

As per the analogy, they come from different places and have different
temperaments.

There is a wood condition, I have forgotten the obvious name. Anyway,
there is nothing you can do, it will not go away, you can't sand,
scrape or plane it out.

I found this reference in Brazilian Mahogany:
http://www.timpan.co.nz/timbers/mahogany_swietenia.html

"Fairly easy to work. The presence of tension wood gives rise to
fuzzy surfaces and deeply interlocked grain causes some grain tearing
in quarter sawn surfaces."

Phillipine Mahagony will not do what he described and African Mahagony is
notorious for just that.
I'm sitting on a few hundred feet of 8/4 African I bought about 5 years ago
and do not want to use it
for the exact same trouble he had with it, as I said it is a beautful
hardwood but a bear to work.

Anytime I call in for Mahogany and they say Genuine, I always ask, Hondourus
or African, It usually will be African, If it is Hondorus they will sate so
and it will always reflect in the Price also.

I can't say.
- as to if this is mahogany, who can tell from just a few words?
- there is a phenomenon called reaction wood, which will do weird things,
but I cannot say I ever heard this being a problem in mahogany. Crotch
pieces should have plenty of reaction wood and these obviously can be
finished just fine.
- it is not sapwood, since this would have a different color
- it should not be interlocked grain, since although this will cause tearout
it can sanded quite smooth (may take a long time in bad cases). Note that
scraping would not do it, since the streak would have to be scraped in the
opposite direction from the surrounding wood). If is interlocked grain then
sanding thoroughly and refinishing (or just refinishing) should solve it.

My guess would be badly interlocked grain, since this will locally behave
like end grain, but it is a guess only.

Well I'm not feeling to good now....

I just bought a bunch of African Mahogany fairly cheap. Most of it has
been planned and was real smooth so I thought I would chance it. Pay
your money, take your chances. I was aware of it's reputation however.
But you know how it is, I thought my experience would be different. Hope
springs eternal.

No doubt to the embargo on Honduras Mahogany . I read the other day that
trees are being cut in the Amazon basin at a greater rate than ever before .
Now when they clear land [generally worthless for grazing cattle and the
reason it is clearcut] instead of bringing the Mahogany to market [ because
of the embargo ] they will just burn it with the rest of the cut timber. The
only people who are happy no doubt are primarily the American treehuggersand
their lobby.

Home Depot was selling some crap wood under the name "Aspen" that does this
same thing. You can sand the hell out of it, and it stays fuzzy. I took a
load of it back for a refund - after I'd cut it to size and started sanding.
Told then it was unusable, even painted. They took it back.

I've been buying "genuine mahogany" from a company that claims it comes from
managed forests in South America. It's great wood, works easy, finishes
great and it's cheaper than poplar or oak, if you're willing to buy it by
the bundle.

Thanks to all who replied - I think George has the best
description of what I have. I did get a lot of tear-out while planing
but put it up to my technique. I didn't say the 'fuzzy' sections were
darker (black streaks?), but they are. The weird part is that now one
of my pieces has been around for a few months, those parts are still
darker *except* for small areas where they are turning very light -
even gray - as though they had slurped up the finish and were drying
out. The only remaining questions is - does African Mahogany have the
same kind of wormholes in it that I read about for the real stuff?
FWW's recent article on Finishing Mahogany showed worm holes just like
the ones in my suspect wood.
I bought this wood by mail from a dealer recommended by
several on the wreck. Not all the wood has this problem. The 8/4 HM I
bought locally has had no problems - but it cost me three times the
mail order price. Looks like I got half lucky with mail order.

Hey Charles,
If you got African I can buy that all day at about 3.50 per Bd Ft,
Whereas Honduras is about 5.50 and if it 8/4 It will cost more.

Mahogany is a lot like cherry in so much It will darken with age and it does
not take to long,
I use what is called a water white acrylic lacquer that has absolutely no
color to it when i open a 5 gallon can I can see the bottom of the can and
see whatever color the can actually is.
I have been doing work for a mens Clothing store for several years now and
it has been all Mahogany and Birdseye Maple with a Clear topcoat.
Everytime I bring them something new they ask me why I didn't stain it the
same color, It is not much but noticable and I generally tell them to wait a
while.

I have a hunch the extra */4 I have in the shop is going to end-up either in
a paint job or being as how it is 8/4 it will make for a nice workbench, Nah
to much work two saw horses and a sheet of ply work just fine.

Send Me a viable e-mail address and I'll send a few pics
Good Luck, George

I would have to disagree. I have worked with most of the woods that
are tradenamed as mahogany, including Red Lauan (Shorea negrosensis)
and White Lauan (Pentacme "various") which are often sold to the
unsuspecting as Honduran Mahogany (Swietenia "various").

These two, in particular, will do exactly as described, depending on
the cut.

Worms, with the exception of the south american variety [about the size of
your finger and which I ma told the natives like to eat alive] for the most
part do not like Mahogany . As a matter of fact the discovery of Mahogany by
the west almost eliminated the use of walnut for that very reason, it's
resistance to woodworm infestations .

I have seen mahogany veneered pine absolutely riddled with wood worm on pine
side with just a few holes showing in the veneered side .

Lots of reasons why not.

Lots of different kinds of wormholes. Big ones, small ones, straight ones,
crooked ones, in what pattern?

Mine and theirs are about 1/4 inch across and occur (to my

holes.

It was an article by Jeff Jewitt, "Finishing Mahogany" in the

find large worm holes near the edge."
I like the natural look so I don't fill them. Jeff uses - gasp

Well now, you have steered the ID of this wood back to the
South American (S. macrophylla) kind. If it were African, I hear you
saying it would not be likely to have worm holes.

OK, that sounds like something that may happen even in mahogany.
