?? Are you asking what 6/4 etc. means or why a 2x4 isn't 2" x 4"?
6/4 etc. is a measurement for rough lumber. The 2x4 isn't 2" x 4"
because it has been milled from a piece of 8/4.

Theoretically, you could ask how thick the wood is before you buy it.
Or you could even measure it. What's your question? And does it need
to be asked?

True in theory, but practice is somewhat different. With the accepted
size of that 2 X dimension at 1.5", it is cut to the smallest possible
thickness that will enable planing to the 1.5". 2 X used to be 1-5/8"
planed, and before that it was 1-3/4" planed (and dry). Certainly you
don't think the mills have gotten LESS efficient in their planing over
the last 80 years?
I can't quote you any numbers, and they would vary from mill to mill,
but I'd bet that for the best band saw mills today the sawed thickness
plus the saw kerf is under 2" today for 2 X lumber.

I am still confused why the category pertaining to quality is linked to a
minimum dimension quantity. Why do you need x inches to get a board of *#+*
quality?
o/w the a/b is a single dimension for hardwood. It is understood hardwood,
and can use the chart for sizes.
Firsts 6 inches
Seconds 6 inches
Selects 4 inches
No. 1, 2, 3A, 3B Common 3 inches
then there is s1s, s2s
or, are these designations qualities' interchangable? I guess, eh. Firsts
6 inches
Seconds 6 inches
Selects 4 inches
No. 1, 2, 3A, 3B Common

Welllll, not exactly. Hardwood boards are graded on the minimum size of
clear cutting that can be derived from them, not on the size of the
board. There are certain minimums a board must reach for each grade.
Your mention of knots is one defect that can lower the clear cutting
size, but so can splits, waney edges, and probably more things I don't
remember.
And, AFAIK, select is a term that means the board meets FAS standards on
one face, but not the other.

The quality - FAS, select, #1 common, etc is determined by yield...how
much clear wood can be cut from a given piece. Each grade also has
certain minimum board dimensions. Here is a link detailing it...
http://www.morlanwoodgifts.com/MM011.ASP?pageno=110
> then there is s1s, s2s
Those have nothing to do with quality or sizes...they indicate surfaced
1 side, surfaced 2 sides.

My lack of a workshop (daughter and her fiance have if full of their
furniture) had been getting to me. I've got 650 bd ft of 4/4 and 8/4
red maple and another 150 bd ft of 8/4 white oak that's been air drying
in another shed for a year that I'm just dieing to make something with.
Think I'll just go for another ride on the motorcycle and clear my head.

It depends... When mills are buying logs they like to consider burls,

Is it necessary to take such a tone with folks here? Would you speak to them
this way were you talking to them in their shop? In yours?
I'm not at all sure, but suspect many - if not most of us are participating
here to learn from one another. And, when we offer a comment, do so with the
honest intent to share what we have learned here or elsewhere upon the
assumption that it is correct. That is, we do not contribute items we know
to be false or incorrect.
The comments are not to an individual (although one does have that option)
but to the group as a whole. Therefore, the ad hominid attacks on folks
doing their best (which may not be up to the standards of the highest
achievers reading) are inappropriate.
Better to contribute the URL of an authoritative source and offer the reader
an opportunity to revisit the subject than to attack his or her
intelligence.
I may be the only one on the list that finds this sort of arrogance
annoying, but I suspect it is less than pleasant for many more.

No one seems to know, so ...
Board thicknesses are basically measured in quarters of an inch.
Thus, rough cut lumber is given as, say, 5/4 meaning 1 1/4"
thick. 6/4 is 1 1/2, and so on.
So if you ask for 5/4 lumber, you're asking for rough cut,
unplaned lumber. Once it's planed, then you get the 2 x 4 that's
actually closer to 1 1/2 x 3 1/2 (take 1/32, depending on humity,
the yard, machines etc etc etc.).
Sfunny none of you geniuses could bother to come up with at least
that much; it's rather elemental, really, although there's really
a tad more to it.
You're still a bunch of ignoramusses for the thread activity,
90% of which was OT from the poster's question. The OP is long

An excellent argument can be made that only someone both ignorant of the
subject, AND unable to read the replies in the thread, could proffer the
above.

Calling everyone who replied "ignoramusses" (sic) is, however, acceptable?

Hmmm ... and just what have you added to the woodworking knowledge of this

There is always the NEXT key at your complete disposal, Gooey ... learn to
wield it and you will be guaranteed to be less annoyed, but, unfortunately,
none the wiser.
... and if you must top post, please learn to trim the extraneous message
header crap out of your replies.
Thanks ...

No, the select will have fewer to no knots. It will be a better quality
board.
A board is graded on both sides, and the worse side determines the final
grade.
The best grade is called FAS. This stands for Firsts and Seconds. These
grades are the best you can get.
Firsts required 91 2/3 % clear area and Seconds required 81 2/3 %
FAS, which is both Firsts and Seconds combined, requires 83 1/3 % clear
area.
The second best grade is called F1F, or FAS1F, (FAS 1 Face).
F1F is a bit better than Select and graded the same, except the minimum
board size is 6" wide and 8' long.
The next grade is Select, or SEL.
This is a combination of FAS on one face and #1 on the other face.
Select boards must be 4" wide and 6' long or bigger.
The better face still needs to grade 83 1/3 % clear for the given area of
the board,
but it does not have to be as large as FAS graded lumber
The next grade is #1 Common. This grade requires 66 2/3 % clear area on the
worse face.
Then you have 2A, and 2B at 50 percent, and 3A, and 3B at 33 1/3 %
Basically, the required clear area drops as you get down to a 3A board.

Close, but still flawed by a basic lack of understanding ... go back and
read the link in the first reply to the OP and take the first step in
educating yourself.
Then on to the following and you'll see how incomplete and far off you
really are:

LOL ... I think the "humity" got to Pop's.

Okay, next time you tell everyone they're wrong... we'll know not to be
irritated.

Who's ad hominid (sic)? I think Odinn said his contribution lacked what
he was accusing everyone elses of lacking. That's not an ad hominem.
Don't identify too closely with your ideas.

Um, are you responding to the wrong person? One person attacked
someone's intelligence. One person did not.

I read it as annoyance and irritation. Arrogance is a different animal,
and you probably won't find it in a setting as anarchic as Usenet (well,
'cept for Tholenbots). The guy just called everyone an
ignoramus--whaddaya expect.
And the question (in the various ways it can be conceived) was answered
correctly in the thread, contrary to the complaint, so irritation was
warranted.

so bird's eye maple is probably rated as 9B, as it has almost only
knots, and burl wood which has no clear area goes ans infinity Z?

Careful: Your comment about the ride brings back an old memory
from when we lived in Coronado, Ca back in '68. My "shop"
consisted of whatever I could squirrel away in the apartment, it
was hot, and dinner was about a half hour away; not time enough
to do anything.
So I jumped on my bike and went for a ride along the Strand to
National City and back; refreshing, felt good, did me lots of
good.
We needed bread, said the wife. So off to the local Safeway I
went, walking, since it was onlyh a couple blocks away. Long
story short: Do NOT stare at guys in suits in alleyways, picking
through the garbage cans! D NOT look at them like they are total
nut jobs and look away when they look back at you!
They called to me three times to stop, and I just kept
walking, hastening my step since I was almost to the busy main
street. Then I heard "HALT! Or I'll fire!" When I turned to
look, he was standing there pointing a pistol directly in my
direction but aimed high.
Keeping the story short: It was the FBI! The local bank had
been robbed. Not really an intelligent thing to do since
Coronado is an island! I met the physical description of one of
the men. My shirt was as described in their description. I had
been alone, on my bike, for the last 45 minutes, and had no one
to vouch for my whereabouts. One really does stand nose to nose
to question you and the other one back a ways, pistol at the
ready. They ask questions like they're firing a shotgun. Back
at the bank, the teller said "NO", I wasn't one of them. I was
late for dinner and had a rather mad wife for the first few
minutes! Woof!
Watch out on those bike rides! ;-)
