How long should live edge slabs dry before kiln drying?
As a general rule of thumb, you should let your live edge slabs air dry for 1 year per every inch thick they are. Then, they should be kiln dried.
How long does it take for live edge wood to dry?
Obviously, a thinner slab will dry much faster than one that's cut a few inches thick. A 2" slab dries in about 6 months, whereas a 3"+ thick slab will take much longer. After your live edge wood slabs are air-dried, you'll want to put them in a kiln for about 1-3 months. Assuming you don't have a kiln, you'll want to find a local shop that does.

Can you dry wood with a dehumidifier?
You can dry any hardwood or softwood in your dehumidifier kiln, but hardwoods need to dry slower to help reduce cracking and checking and require closer monitoring. ALL WOOD that goes into your drier needs to be end-sealed, and it should be end-sealed with a recommended product.
How can I dry wood fast without cracking it?
Lean the slice against a wall or prop it up on its side in a warm, well-ventilated location such as a garage, basement, or shed. Let it dry for up to a week so the solution can evaporate and the wood can dry without cracking.
Do you have to let wood dry before using?
The answer is dimensional stability and it is one of the main reasons wood must be dried. Wood begins to shrink in width, and thickness when the moisture content starts to get below 30%. The amount of shrinkage varies by species.
How long should wood dry before using?
Drying Wood Air drying of wood takes time, lumber stacked and separated so that all sides of lumber are exposed. As a general rule of thumb, it requires 1 year for each inch of lumber thickness for wood to dry sufficiently to be worked. As we know, time is money, and that's a big investment.
Can you build with fresh cut lumber?
Building with green lumber for timber frame construction can save time, money and energy. With green timber, you can begin building right away without having to wait for the wood to dry, or having the added cost for kiln drying, which uses environmentally damaging fossil fuels during the drying process.
How do you get moisture out of wood?
Place a dehumidifier in the center of the room once all of the standing water is removed. Set it to the highest extraction setting possible. Turn it on and leave it running for at least 24 hours to pull moisture from the boards. Place fans blowing across the surface to further aid in drying the wood out.
How do you dry wood without a kiln?
Kiln Dried Wood Without a kiln, you should try to achieve an air-dry moisture content of 15-20 percent. Further moisture reduction occurs when you move the boards indoors where they'll eventually reach their equilibrium moisture content (EMC).
How long should lumber dry before building?
The traditional rule of thumb is to let the lumber air-dry for one year for each inch of thickness, but this is only a general rule and close monitoring of the lumber, especially with the help of a moisture meter, provides more flexibility.
What is the fastest way to dry wood for woodworking?
All you need to do is set up a decent dehumidifier beside the stack of wood to be dried, let it run, and it will suck the moisture right out of the wood. This can speed up the drying time from months or weeks to just a few days. Even better is if you add an air fan into the mix to produce some extra airflow.
Do you have to dry wood before building with it?
The answer is dimensional stability and it is one of the main reasons wood must be dried. Wood begins to shrink in width, and thickness when the moisture content starts to get below 30%. The amount of shrinkage varies by species.

Turn it on and leave it running for at least 24 hours to pull moisture from the boards. Place fans blowing across the surface to further aid in drying the wood out.
How long does it take for wood to dry in a kiln?
For this one inch lumber, green-to-dry kiln time is typically 5-6 weeks, or 35-45 days. So based on the prior paragraph a theoretical drying time for 2 inch thick wood should be closer to 140-180 days, or close to half a year. Both research and the experience of many operators will tell you this can be pushed closer to perhaps 90-100 days as a practical minimum for most species. And the 3” slab? Let’s just say the world experts in wood drying don’t even address this for oak, on the assumption that (with the exception of live edge artisans) no one in their right mind would take the time needed.
What is drying rate?
For the scientists and engineers in the audience, drying rate is a squared function of wood thickness. In other words, if you double the thickness of a board, your theoretical drying time is four times longer. This can be adjusted or “cheated” to some degree, but cheating too far cheats the user of the wood, and that user may not know or see the consequences until they are working the wood, or even worse, after their work is completed.
What happens if you block airflow to one side of a wood slab?
If you block airflow to one side of your slab but not the other, then moisture will only contact one side of your slab and your wood will move — even in an air-conditioned space. To allow proper airflow, place “stickers” under your wood (1″x1″ sticks) to make sure airflow can hit both the top and bottom of your slab.
What is the dry percentage of wood?
The Drying Equation. First, you want to confirm with the mill or woodshop that your piece of wood has been properly dried to a moisture content of under 12%. Depending on the species, between 8% – 10% is preferable, but the important number is 12%. Wood can either be “air-dried” or “kiln-dried, the differences between the different type ...
Why seal and finish solid wood?
It is always best to seal and finish solid wood slabs to avoid cupping and abnormalities from temperature and humidity conditions. That means it’s best to purchase your untreated wood at a time when you will be able to use it. Do your best to get your project moving quickly to minimize the risk of cupping.
Why do you wrap wood slabs with plastic wrap?
Plastic wrap makes slabs airtight when you can’t maintain your conditions. Wood conditions stay consistent when no moisture can get to the slab, so wrapping yours tightly with plastic wrap until you can continue your project will go a long way in making sure the process stays on track.
How to dry wood in a kiln?

How long have Oregon slabs been drying?
Turns out that rule can be true, but more often that not, it isn’t a good rule to follow. Those eastern Oregon slabs have now been drying for six years and still have areas of moisture of over 30%. View fullsize. Pinless meter on bottom reading much more accurately than the pin meter on top.
What is dry wood?
Also referred to as green wood. The wood will warp and twist as it dries, so you need the wood to be at equilibrium before you start working on it. The definition of dry wood varies by the part of your country you are in. Dry is actually not the most accurate term. A more accurate term would be “has it reached equilibrium moisture content (EMC)?” However you should know, nobody says that, and “dry” is still the expression we have. All that EMC means is the percentage of water left in a piece of wood when it reaches equilibrium. Either through air drying or kiln drying. Meaning, all wood will have some moisture left in it. No matter how long it sits. EMC varies by region, Oregon is around 9%, Arizona is around 6%, and a humid area like Florida is around 12%. For comparison, a fresh cut walnut tree might have moisture content (MC) of 60%. A slab sitting for a year or two might still have a MC of 30% or more.
Why do wood slabs curl?
This is more than a coincidence. The highly figured woods with quilt or curl pattern are caused by stresses in the tree when it is alive. So the highly figured woods are very prone to twisting/cupping/bowing due to this internal stress.
Who invented the live edge?
Live edge is a seemingly modern trend that has actually been around for a long time. Most attribute the live edge movement to George Nakashima. Nakashima was a Japanese-American architect and woodworker who made gorgeous live edge tables back at least as far as the early 60’s. While Nakashima brought popularity to the natural edge movement, it would be hard to say he was actually the first in human history to fashion a table with two natural edges. And as far as I know, Nakashima never made that claim.
Do resin tables stay flat?
The very curvy slabs that make the best resin tables run into the same issues as figured woods. They tend to not stay perfectly flat when drying. They are also likely to have knot holes and other imperfections that will need addressing.
Can you work with wet wood?
You DO NOT want to work with wet wood. Also referred to as green wood. The wood will warp and twist as it dries, so you need the wood to be at equilibrium before you start working on it. The definition of dry wood varies by the part of your country you are in. Dry is actually not the most accurate term.
Does Goby sell rotten wood?
It is worth mentioning that reputable suppliers will still sell wood slabs with rotten spots, cups, and twists. Goby will almost always point out areas of significance like cracks and soft spots. Situationally, they won’t even charge for those areas.

How to bring a wood slab to a consistent thickness?
Bringing a wood slab to a consistent thickness by flattening the other side of an already jointed wood slab. Planing and jointing work hand in hand.
Why is it important to weigh wood slabs?
Weighing the slab of wood down helps to prevent warping or distortion, which is especially important during the initial drying stage when passing through green to an ambient equilibrium moisture content (EMC).
Why is my wood slab cupping?
Cupping is a situation that involves the curvature of the wood slab. Cupping is caused by uneven drying; one side dries faster than the other, shrinks, and pulls the outer perimeter upward.
How to keep wood from cracking when drying?
Using salt is a simple way to help prevent cracks from forming as the wood slabs dry without using harsh or pungent chemicals . You must mix three pounds (1.4 kg) of table salt with one gallon (3.8 L) of water.
What is a wood slab used for?

A thin slab of wood can be used as a regular vegetable cutting board which can be displayed in your kitchen by hanging it along the walls to give your kitchen a beautiful look. A wood slab fixed vertically along the wall of your bar can be a beautiful wine rack to organize your bottles and keep them handy.
How long do you air dry a slab?
The kiln dried slabs are typically air dried for around two years, then put in the kiln. We recommend only using kiln dried slabs because this will keep the slabs from warping as they naturally dry if you build something out of them when they're green.

How long does it take to dry wood?
The traditional rule-of-thumb for air-drying lumber is to allow one year of drying time per inch of wood thickness; this adage obviously only takes a few of the aforementioned variables into account, but it’s at least a rough starting point in understanding the time investment required in order to properly air-dry lumber. In situations where green wood is to be processed into usable boards, (especially in the case of thicker lumber), a kiln is frequently used to control the drying process. While there are various types of kilns used to dry lumber, the basic premise is usually the same: a large insulated chamber or room is used to balance and control humidity, temperature, and airflow to safely and efficiently bring wood down to an acceptable moisture content. The main advantage of a kiln is that with the increased temperature and airflow—all while carefully maintaining and controlling the ambient humidity—the wood can be dried much more evenly, minimizing any sort of moisture gradient between the outer shell (which dries very quickly) and the inner core (which slowly equalizes moisture with the shell). Thus, a kiln is able to dry wood much more evenly, and it’s this uniformity in drying that allows it to also dry the wood quickly—simultaneously avoiding the drying defects usually associated with rapid, uneven drying.
What happens when wood is kiln dried?
But kiln drying may also introduce internal stresses into the wood—particularly if an improper kiln schedule is used, or if corrective measures are not employed—resulting in a condition known as case-hardening. This defect is caused when the outer shell begins to dry faster than the core: the shell tries to shrink, but is inhibited by the still-wet core. If the moisture difference between the core and the shell is too great, the shell can dry in a stretched condition. Later, as the core eventually begins to dry and shrink, the condition is reversed, and the stretched shell prohibits the core from completely shrinking. In extreme instances of case-hardening, the core can split and check in an irreversible condition called honeycombing .
Why seal endgrain?
Sealing the endgrain forces the moisture to exit in a slower, more uniform manner. If this is neglected, the ends will tend to shrink faster than the rest of the wood, creating tremendous stresses on the piece that’s ultimately only relieved with endgrain checks—a very common drying defect.
What is a drying cabinet?
A drying cabinet can be nothing more than a simple wood cabinet with an incandescent lightbulb on a dimmer to finely control the light output —which in turn dictates both internal temperature and consequently relative humidity. Many thermometers (both traditional and digital) sold by big-box retailers also feature a hygrometer with a somewhat accurate readout of the relative humidity; the ability to know the RH of both the drying cabinet and the wood shop proves to be a helpful and prudent investment.
How to prevent warps in lumber?
Use proper stacking techniques. As mentioned previously, by far the most important deterrent to warp is the adequate stacking, stickering, and weigh ing of a lumber stack. Avoid juvenile wood. Juvenile wood is wood that is formed during a tree’s early years of growth, and can be thought of as an extension of the pith.
What are the defects in wood?
This can result in defects such as: bow, crook, twist, or a combination of two or more defects simultaneously.
What happens when wood shrinks?
When a wood species has a high T/R ratio, it will tend to shrink in one dimension more than another while drying, causing distortion or warp. A good way to visualize the tendencies of wood during drying and shrinking is to picture the arc of the growth rings trying to flatten themselves out. (This of course is not actually the cause of the shrinkage, but it serves as a good memory tool to help visualize dimensional changes.)
