Hi porch dwellers- Can anybody help with the approximate weight of hard maple (the type that an old butcher block would have been made of) per cubic foot? Thanks, Joe in NH |

The "Wood Handbook" of U.S. Forest Products Lab lists an average dry .63 specific gravity for the heaviest Maple (Sugar Maple). That equates to 39.3 pounds per cubic foot!.--ErvSaws On Wed, 6 Aug 1997 19:25:29 -0400 "J.

My copy of "A Natural History of Trees of Eastern and Central North America" by Donald Culross Peattie lists sugar maple at 44 lbs per cubic foot, dry weight. BTW this is a wonderful book and is full of not only the natural history of the tree species but also descriptions of uses for the various woods. Part of his description of sugar maple: "As a street tree, Sugar Maple is surpassed in form adapted to traffic only by White Elm; and it is far less demanding of water, less injured by disturbance to its roots when pipes and drains are laid. But it suffers from city smoke and industrial gases; that is what keeps it a village tree, a tree of old colonial towns. On the lawn it develops, from its egg shape in youth, a benignant length of the lower limbs which is ideal for the play of children. The fine tracery of the tree in winter stands revealed in all its mingled strength and elegance. In spring the greenish-yellow flowers appear at the same time that the leaves begin to open like a baby's hand. The full spread of its foliage in summer gives what is perhaps the deepest, coolest shade granted by any of our northern trees...Under forest conditions, Sugar Maple may grow to 120 feet, with a 3- or 4-foot trunk clear of branches half the way - a cylinder of knot-free wood almost unrivaled among our hardwoods. It is immensely strong and durable, especially the whitish sapwood called by the lumberman Hard Maple; a marble floor in a Philadelphia store wore out before a Hard Maple flooring laid there at the same time. Few are the standard commercial uses for lumber where Hard Maple does not figure, either at the top of the list or high on it. Tough and resistant to shock, it becomes smoother, not rougher, with much usage - as you will notice if you look at an old-fashioned rolling pin." **************** TomPrice@a... Will Work For Tools |

Oops! I didn't reply to your last question re the availability of the Wood Handbook. It was written largely for use by wood technologists and engineers. Real title is "Wood Handbook--Wood as an Engineering Material", and is Agricultural Handbook #72 of the U.S. Department of Agriculture's Forest Service. As a result it has extensive discussion of wood types, behavior, drying,fastening, cutting qualities, physical properties of all kinds, and problems in use and their resolution. I still believe it is available from the Superintendent of Documents in Washington, D.C. for a nominal fee. I'll have to get the address for you. It is available both Hard and Soft bound. Is 466 pages! I was in on several revisions of it over some 30 years. --ErvSaws On Wed, 6 Aug 1997 18:24:02 -0700 elschaffer@j... writes: >The "specific gravity" of materials is their weight divided by the >weight of 1 cubic foot of water (which weighs 62.4 lbs/cubic foot). >Voila (that's "wallah")!, so 0.63 X 62.4 = 39.3. >--ErvSaws >On Wed, 06 Aug 1997 17:38:39 -0700 David Hunkins drhunk@c... >writes: >>At 05:06 PM 8/6/97 -0700, you wrote: >>>The "Wood Handbook" of U.S. Forest Products Lab lists an average dry > >>.63 >>>specific gravity for the heaviest Maple (Sugar Maple).

Joe, According to "General Engineering Handbook" published by McGraw-Hill 1932, the average weight of Hard Maple is 42 lbs/cuft. It does not indicate the moisture content of the wood at that density. I hope this helps. This is a great galoot book. Examples of galoot info: - barrels of butter, lard, etc. weigh 32 lbs/cuft, - wax at 60 lbs/cuft - charts for the strength of various timbers oblique to the grain - comparison of various glues: animal, casein, vegatable, blood, liquid Great galoot stuff ! > Hi porch dwellers- > Can anybody help with the approximate weight of hard maple (the type > that > an old butcher block would have been made of) per cubic foot? > > Thanks, Joe in NH > |

When I said the dry weight of Sugar Maple was 39.3 lbs/cu ft, I was citing "dry" weight---that is with negligible (less than 1.5%) moisture in the wood. Usually the moisture content of wood in furniture in the Northern U.S. is about 12% by weight. Sooo, the weight becomes 44 lbs/cu ft at this moisture content. --ErvSaws On Thu, 7 Aug 1997 10:27:34 -0500 "GACHASSIN, KRIS" GachassinK@b... writes: >Joe, > >According to "General Engineering Handbook" published by McGraw-Hill >1932, the average weight of Hard Maple is 42 lbs/cuft.

Many thanks to Bill & Erv & all the other Galoots that have helped me with the weight of one cubic foot of hard maple. Now I'll tell why I needed to know: My SWMBO is looking at an antique butcher block. The solid top section is 24 x 36 x 18, which translates into about 9 cubic feet of solid maple! According to all your calculations, this thing probably weighs over 400 pounds. After checking the construction of the floor joists, with a little reinforcing, I could just end up with the "ultimate workbench", and in the kitchen, no less! Eh, Eh, Eh...(I'm not has dumb as I look!) Now I just have to figure out how she is going to carry it up the steps and into the house. Thanks! Joe in NH |

According to Bootle's "Wood in Australia", air dried maple from Canada weighs in at 740kg/cubic metre, and from USA at 730kg/cubic metre. "What kind of units are they!!??" I hear you saying. Shuffle the decimal point a few places to the left, and we have specific gravity. Easy, huh? More'n one, and it sinks in water. You *could* calculate it out to around 46lb/ft3, but why bother?

Hang on a tick - this stuff is saturated with dried bloo.... glue, fat, bone, and all sorts of "other" matter. All the previous data was for "clean" wood - better ask the question again.

Ernie: I certainly concur with your view that the wood won't be saturated with blood and other "gunk". Maple is not very permeable, so unless nearly perpetually soaked in water, it just won't pick up enough with daily use and wiping off.
