Wood dry out curve

Sep 23, 2019 Because wood comes from living trees, it changes shape along with its moisture content. When it dries, it contracts, and researchers want to use that contraction to create curved structures

    by Eric Meier Allowing lumber to passively sit at a given humidity level in order to obtain a desired EMC (air-drying) may be the simplest and least expensive method of seasoning wood, but it is also the very slowest. Drying times can vary significantly depending upon wood species, initial moisture level, lumber thickness, density, ambient conditions, and processing techniques

    Nov 29, 2002 Drying rates also provide a method of estimating drying times. For example, if an operation is drying 4/4 upland red oak at a rate of 3 percent moisture loss per day and it is drying a load from 30 percent MC down to 7 percent, it would take almost eight days plus equalizing and conditioning to dry the load. Conversely, if it takes 23 days to

    As green wood dries, most of the water is removed. The moisture remaining in the wood tends to come to equilibri-um with the relative humidity of the surrounding air. Correct drying, handling, and storage of wood will minimize mois-ture content changes that might occur after drying when the wood is in service. If moisture content is controlled

    May 24, 2018 Using steam to heat timber is perfect, as it takes it to exactly the right temperature while preventing the timber from drying out at all. After reaching 99–100 and immediately upon removing timber from a steam box, the timber is flexible enough to pull around curved jigs with the aid of specially designed compression strap clamps

    The kerf cutting method is another way to bend wood and is also known to be very effective. This uses almost the same technique as wood lamination but with a few minor differences. Cut notches 2/3 of the thickness of the wood. The kerfs should be located on the inside of the curve you want to bend

    The main idea is to add moisture back to the wood and then clamp it into shape. That way as the lumber dries it is forced to a specific shape. Below we listed a few different forms. Basic – Spray down the lumber and let the wood absorb the water. Once it has done so, clamp the board into position and allow to dry

    Thicker members like 6x6 posts tend to dry out unevenly and are especially susceptible to extreme checking. Wood reacts differently in the various climates across the U.S., and different species and grades also have differing appearances. Straight from the lumberyard, lumber components likely already have some cracking and checking present

    Free water on or in wood dries quickly but bound water within wood cells takes much longer to dry or requires kiln drying or other measures for its removal. [2] The fiber saturation point of wood or wood's FSP is defined as the moisture content of that wood when all of the free water has been removed

    Compressed wood is a type of wood that is not meant for gentle bends unless you have full support during drying. The wood is eager to bend therefore if you want a gentle bend then it is very hard to keep it from moving when you are in the drying stage

    Jul 21, 2017 That's pretty much true -- it can take nine months to a year for some firewood to properly dry or cure. Drying time varies with the cut; 2-foot pieces (a standard firewood length) will dry in about six months, while 4-footers may take a year. Split wood dries faster because it has more area exposed to the air than full logs with bark

    We borrowed this idea to make a template for drawing the curves on the leaves of the drop-leaf table in WOOD magazine issue 181 (December/January 2007/2008). In this case, a drawing like the one at insert directional shows the beginning and end points of the curve, plus several intermediate points
