Hi folks,
This might seem like a stupid question, but I was just wondering what CDX actually stands for?

C=best face veneer
D= worst "" ""
X= outside / eXterior glue

Oh, Round One ... your answer is correct but brief. All plywood has two sides, or faces, and the quality of the face is designated by a letter ... A being the best and D is utility grade. It is rare to find ply with the same quality veneer on both faces, except oak, cherry, and other high dollar hardwood plywood, so you usually have AB, BC, and CD. The D grade is nasty looking, but structurally sound. You wouldn't want to use it for anything that was visible. The A grade would be very nice, with no knots, splits, etc ... in otherwords a face that you could stain and use for bookshelves or similar.

Supposedly there is an "N" grade, but I have never seen it. Anybody know of this?

"N" grade, but I have never seen it
Only in the cabinet trade--it was the only way to get red oak veneer ply with color & grain matching, in bundles, consistent trhough a batch. Or so the purchasing people told us.
At least until they bought the vacuum press & worked out that they could make their own . . . Occupational hazard of my occupation not being around (sorry Bubba)
true..how come I never see ACX?
I figgured he'd get the gist of it..BTW AC is usually sanded on the A face..

If it's X it'll need at the very least a heavy stain to protect it from the elements, so there's no need to have an A quality face.
Should also mention that there are two grades between interior and exterior: Exposure 1 and exposure 2. These are for things like floor sheathing that may be exposed to some weather during construction. I forget which is which, though, or what all the presumed applications are.
And, of course, beyond exterior there are treated and marine grades.
Ranked from highest weather resistance to lowest:
Exterior
Exposure 1
Exposure 2
Interior
CDX is actually exposure 1, not exterior as many believe.
Jon Blakemore
Thanks guys, I guess it's not such a bad question afterall!
And here I thought CDX was a railroad company! :)
CDX is the Canadian Exchange where a lot of Canadian stocks are traded.
Much like the NYSE in the US.
There's actually only about four bad questions for this forum:
1. Can I use sheetrock screws to hang cabinets?
2. What are the black diamonds for ont eh tape measure?
3. How much can I save by GC'ing my own house (part time after work and on weekends)?
4. What's the best cad software that will automatically draw 3d plans for under $100?

But Ed,
If we eliminated #1 and #2, there goes half of our entertainment here.
Jon Blakemore
You forgot one. Don't know where to rate it, but definitely infront of #4.
"I want to take out a 12 ft wall in my house. What size beam do I need?"
You're right ... the beam size question, delivered in two sentences without pictures or anything else ... that's in the top three.

what do i need to do this, this and that to my house. No clue what part of the world they're in or their climate...
How much per square foot...
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming.... WOW!!! What a Ride!
Or the familiar:
"How much does a house cost?"
Jon Blakemore
How much should I charge for this?
I find the subcatergories of your question just as entertaining. "how much for concrete work" or "whats the going rate for hanging and finishing rock"
However none of it gets as old as going over to knots and seeing each week, "what table saw should i buy" or the notorious "should i buy a left or right tilt saw" At least here on BT people can have fun, knotheads are too uptight over there to have fun with dead horse questions
Knots ... I would imagine that two worn out questions over there would be ... should I flatten my work bench again, it's got a 0.0000001" belly in the middle ... and ... how sharp should I hone my chisels?

Ed, can they see the top of their work bench?
I only clear as much space as needed for the job at hand.
The whole thing nikkid at once?

I work in a lumber yard and I get all kinds of fun ones like I need a door, waht size, standard, well what size, front, bathroom, the size on my house, etc arent homeowners and diyers entertaining
5. Trusses ain't so complicated, howcum they costs so much? Occupational hazard of my occupation not being around (sorry Bubba)
And is it ok if I cut out just a couple of the little pieces of wood in the middle?

cut out just a couple of the little pieces of wood in the middle
LoL!
Or all of them, "they's jus' in the way." Ooh, now that is "fixed,"
6. how much to turm my attic into another floor of my house?Occupational hazard of my occupation not being around (sorry Bubba)
Another question which I think should have its very own folder somewhere off in the wilderness is the flat roof/deck one which seems to come up about once every two weeks. On the other hand, there was one two weeks ago that was different and more interesting.

true..how come I never see ACX?
Some of the marine-grade fir is a BC, and it is full Exterior grade, not Exposure I.Occupational hazard of my occupation not being around (sorry Bubba)
I had gotten ( does that sound right?) Okume in 5mm..marine grade A/B it think it was..a 5x10 sheet was 108.00 ten +yrs. ago..whew..it was for my boat..a 16' sharpy skiff..lapstraake weighed in at 75lbs.
Cool boat...was in my shop ( on it actually) when it burnt down..sorely missed.

Sharpies are pretty. Shame to hear one went up in smoke. I've helped build a couple of flat iron skiffs, one of which actually saile worth a darn <g>.
Some of the marine ply out there is very cool. None have ever seemed to be inexpensive. But then compass timber prices can have abit of sticker shock, too . . . Occupational hazard of my occupation not being around (sorry Bubba)
There is B-B-Plyform for formwork
Probably close to 100$ a sheet @ todays prices.
I can't remember but I believe "N" is for natural.
I'm pretty sure N grade veneers have to be "Flat sliced" (not rotary cut) for a solid wood look.
they may even have to be Book-matched.

Crap both sides. Xpensive too.
Doesn't work, I know, but accurate.

Now aren't you really glad you asked that question?
