board feet and quarters
A board foot is defined as a 1' x 1' x 1" or combinations to get 144 cu inch of material. When I go to the lumber store a 1" thick board is actually 3/4". When I see lumber listed as 4/4, 5/4, 6/4, 8/4, etc, what should I actually be able measue it out as? If I have wood that measures as 2" thick with my tapemeasure, how would I express that in quarters? This likely has come up before, but I just got into discussion with a 50%er engineer who just absolutely "knows" because the degree in his pocket says so. Pete |

If I have wood that measures as 2" thick with my tapemeasure, *how
would I express that in quarters? Expressed as: Your tape measure is worth 8 quarters (or $2.00). Comparable to a $2 watch. From your lumber yard, you will likely not find finished lumber that measures a full 2", but slightly less than exactly 2". This finished lumber measure would be expressed as 8/4, as the original rough cut stock, it came from, was originally a full 2" measure. Only rough cut lumber will be a full 2" measure, unless it is a special cut of particular lumber. You won't find $2 watches at the lumber yard, either. .... I don't think! ..... maybe? Sonny |

Sonny, tell your idiot engineer to stick to his line of expertise.
There is a ton of information on this phenomenon that started as soon as sawmills began to sell planed wood. So maybe a couple of hundred years ago.... To overly simplify, a board foot is the size of the board BEFORE it was planed or smoothed. So a 1X6 was a board that began as 1" thick, and 6" wide. However, to make it convenient, you began to be able to buy planed boards from the mill. Planing decreased the thickness on each side and the edges, so the sizes you see now reflect the fact that the wood has been processed to a consistent size, or its finished size. However, the mill still cut it 1"X6" so they would have enough material on the board to smooth it. You didn't think you would get that extra material free, right? So you are charged for the board itself when rough, as well as the convenience of smoothed faces. To drive that home, go to a real hardwood lumber store (NOT HD) and ask for a 1X6. They should ask you "nominal (unplaned) or smooth?". If rough, you can take the board home and plane it yourself. Make to your own smooth boards to your dimensions using nominally sized lumber. As far as quarters go... think about it. Maybe since it's Thanksgiving, think of an pie as an inch to visualize it. With that in mind, think of one quarter of a pie as "a quarter of a pie". So to extrapolate, if you have one quarter of an inch, then you have..... wait for it..... here it comes..... one quarter of an inch! So 4 quarters would be..... one inch! Five quarters would be..... an inch and a quarter. Eight quarters would be two inches, etc. Just count the quarters on your tape and you will have it. IME, the quarter system of describing wood sizes is used only to describe thickness of rough (nominal) lumber. It is not used to determine width. You won't find an lumber man that asks you if you want 4/4 (four quarters) by 24/4 (24 quarters) by 400/4. You should also know that unless it is in a specific purpose lumber, nominal sizes almost always refer to hardwoods, not softwoods. Some engineers are pretty bright fellows, but this one sounds brand new. Show him this to help educate him as to how BF is calculated, and after that DAGS the key words. http://preview.tinyurl.com/c7nlgl Check out the highlighted words in this book, page 216. "Understanding Wood" (to me) is the absolutely undisputed king of reference books on all things wood. http://preview.tinyurl.com/2fs4d32 Robert |

Like lumber where sizes are determined in the rough unfinished state, paper is determined in the mill sizes that the paper mill standardizes. Copy paper, known as Bond paper because it is used for business letterhead and forms, and now used for copiers is based on a ream, which is 500 sheets, of standard sized paper. Bond paper is produced in the standard size of 17" x 22", and 500 sheets will weight 20 pounds or 24 pounds respectively. Other sizes are produced but the weight is based on the standard size. |

12/4 = 3"
8/4 = 2" 4/4 = 1" The store bought stuff usually is listed as a nominal sizes. IE: a 2 x 4 x 10 was 2" x 4, but has been planned / dried a bit to 1 1/2" x 3 1/2" On 11/24/2010 12:10 PM, wrote: A board foot is defined as a 1' x 1' x 1" or combinations to get 144 cu inch of material.

BTW, when buying rough lumber, you measure a board at it's widest point to calculate board feet. Thus a 4/4 board that is 8 ft long and varies from 9" wide at one end to 12" wide at the other is considered to be an 8 board foot board. (It is assumed to be 12" for the full length for BF calculation purposes.) It's a little gotcha that gets passed on. Not at the hardwood supply place where I do business (Fine Lumber here in Austin TX). If there is any significant variance in width they will take several measurements and compute the average width and charge accordingly.

The hardwood wholesalers around here sometimes average, and sometimes calculate by the narrowest useable part. Depends a bit what you go asking for, and how it fits your cut-list. If you will be able to use most of the wood, they average it. If there will be significant waste because the board is non-standard - and they have nothing else, they often "eat" the waste. |

And have used an honest- to-goodness Lin-o-type machine. 0grin I've also written computer software to calculate postage costs for mailings, given only 'how many pieces' of 'what kind of paper' went into the envelope. {This program had enough 'smarts' in it that it would tell you if eliminating _one_ (or sometimes two) sheets from the run would save on postage. Over time, made for about a 10% reduction in postage costs for the mailings.} One of the _few_ times my print-shop *didn't* have an 'instant answer' for me was the day I called up and asked "the {mumble} paper stock we use, what's the _basis_size_ for it?" He'd _never_ had a customer ask *that* question before. grin |

Actually, there -is- a 'standard' size for every type of paper -- the so- called "basis size" for that type of stock. The size is just different, depending on the type of stock. involved. The 'full sheet' sizes for the various types of paper are 'de facto' standardized across manufacturers, simply because they have to be fed to the same presses. grin |
