newbie question
I've read and seen timber dimensions that is a little puzzling to me. I know
what a 1x2 is or a 2x4 or a 4x4 but what is a 5/4, 4/4, 8/4 or whatever Y/X is ? tia |

Yes, but we try to be a little more confusing. If I buy rough 4/4 hardwood,
it's about an inch thick. The same item, S2S (sanded two sides) can be from 3/4 inch to nearly 7/8 thick, depending on where you get it, but it's still called 4/4 lumber at yards, while places like Home Depot probably say 3/4 inch.

And to hopefully clarify even a little more for the OP, the 4/4 surfaced hardwood or graded softwood from a mill/supplier is still listed/priced as "4/4" because that's the raw material from which it came and is priced on a bd-ft basis rather than piece-wise or by the linear foot...(retailers, otoh, may price on other bases, typically much more favorable to them ) Construction material is sized on nominal rough mill dimensions from historical sizes although now have standardized on nominal finished dimensions. At one time a "2x" was about 1-5/8" thickness and even earliear was rough-sawn at the nominal 2" thickness... And, just in case he's unaware of the definition a "bd-ft" is a volume measure of 1" thick by 1-ft width by 1-ft length. |

Guess it's best to take the calculator along ...unless, as you say, you have enough past history to know it's where you're going no matter the grief... My previous house was built in 1928; all the framing is rough-sawn *beech* two-bys. Floor joists all beech 2x10s, an honest 2" by 10", on 16" centers. Even after all those years, only a little sag and hardly any bounce in the floors. Ahh, the good old days... While in VA many years ago the local school board took down a ca 1880-90 school building. Went to look at some of the material they were selling thinking primarily of getting the kids a slate blackboard. Looked at the timbers and started to get sorta' excited... Surrepetitious check w/ the knife confirmed my suspicions--went home, got buddy, truck and checkbook(s) and we bought about 4000 bd-ft of walnut beams and studs from 2xX to 5x10-20-ft lumber for $1500! The downside was in running electrical wires in the basement or the attic. The tool kit included a drill, a spade bit, and a ******* file to resharpen it every three or four holes. Been going through renovation/restoration of the old barn (1918) here built of virgin growth southern yellow pine--hard stuff, indeedy! |

Woodies use all dimensions in quarters, 1/4, 2/4, etc. 8/4 = 2" Keep in mind that these measurements are nominal, not actual. Just like a 2x4 isn't actually 2 inches thick or 4 inches wide, 8/4 lumber is not really 2" thick if it has been dressed to a semi-usable state. You typically lose 1/4 inch in thickness to the planer. Thus 4/4 lumber that has been surfaced is really 3/4" thick (just like your typical 1x construction lumber). |

I wish they wouldn't do that. It drives me up the wall. OTOH, the prices are great and so is the wood, so I guess there are compensations. |

Wow, interesting !
Then on a historic note, why the "1/4" inch has been chosen to name lumber ? My first guess would be the thickness of the saw blade used ? "Dave Hall" a écrit dans le message de news: ...

Thanks, Doug and Suane. True on the planing; don't think I've ever seen it
really sanded, but that's what they call it. As for size, I agree that many yards give you a nominal 13/16. However, a few stores call it 4/4 and have dressed it down to 3/4 (stores, not yards). Finally, I just got 100 BF of 4/4 S2S ash, and it measures 15/16. So what can I say? I live in the desert, and it's now raining yet again:-) Hopefully, with your additions, he'll have some idea what he might find. Oh yeah, we forgot S3S which has one straight and square edge, and (though the term isn't often used) S4S which is what Home Depot sells..

Some hardwood dealers surface their stock, usually for a fee. Some skip plane the boards to allow for the person buying the stock to determine what the grain will look like. -- Jack Novak Buffalo, NY - USA (Remove "SPAM" from email address to reply) |

More that rough sawn at mill in quarter-inch increments is sufficiently fine to allow for whatever final thickness an end-user may wish -- of course, w/ modern computer-controlled and band mills one could make anything one desired, but most mills (except for veneer, of course) are still pretty coarse... How thick the blade is isn't really particularly important to how thick a board is sawed off the slab other than it has to be stiff enough to not flex. |

Wood is cut green at the mill and it shrinks when it dries. The sawyers have to make an educated guess when they saw the log for the required yield. I imagine 1/4" is as close as they care to shoot for. -- Jack Novak Buffalo, NY - USA (Remove "SPAM" from email address to reply) |

That'd be Hollingsworth Lumber in Russiaville (pronounced roosh-uh-vill, BTW), about 5 miles or so SW of Kokomo. The board-foot prices for any given species all work out to be the same within a few pennies, regardless of width, so it's not like they're trying to cheat anybody.

mac, as I mentioned, it will vary. I just bought S2S ash from a lumberyard,
and it measures 15/16". From another yard, it was 13/16. Further, S2S says nothing about the width, and this ash varies all over. You're talking about dimensioned lumber.

Don't know of any who do adjust for surfacing (other than, perhaps some of the mail order places who deal in specialty project pieces and I'm not even sure of that for other than thin pieces which aren't normally priced by bd-ft anyway). As I noted previously, it's based on the raw stock size before any surfacing. Any place that will base the bd-ft value on surfaced thickness will adjust the price/bd-ft to reflect the original stock as they will certainly have that as the cost basis in buying the material. And in case I misinterpreted your meaning above, actually, they calculate by thickness, just that in the case of 4/4 stock it's "1" so it numerically is the same. Buy some 6/4 stock and see if they "ignore" it then... And for point three, just in case, the point was to define a bd-ft to OP who I thought as he noted he was new to buying hardwoods might just not actually know... |
