dry kiln wood

kiln dry lumber at home : 6 steps (with pictures) - instructables

Kiln drying your own wood at home can be a great way to sustainably harvest the materials around you, and dry it fast enough to build furniture with. If furniture is made with wood that is too wet, it will continue to dry and crack, possibly ruining the piece. This instructable takes you through the process of raw wood in the spring, to dry lumber in the fall. You can do this with any kind of wood.

Finding rough timber and logs to mill is a lot easier than you may think. There's always someone around that's trying to get rid of a fallen tree or wants to take down a dead tree. Calling around to local tree trimmers and arborists can lead to some great opportunities. These people make a living with trees, and if you can offer them a fair price for a log, they'll often choose to sell it because it saves them the work of disposal, or processing it into firewood. Put an add in the paper, call your local city or municipality and ask about who deals with downed trees. The list goes on and on, but you can definitely find something. The term "windfall" comes from just that, wind storms can mean lots of wood. Once you've gotten the wood, local sawyers are plentiful in most areas, and many will bring their portable sawmill to you for a very reasonable rate. I pay $100 an hour here, and a good sawyer can do a lot in an hour. Worth their weight in gold, these hardworking folks are a woodworkers dream come true, and they often have a stock of amazing, local woods for sale.You can also choose to mill it yourself with a chainsaw, which I partially do sometimes depending on the log. If you choose to do this, read up, and follow all the safety precautions of those tools. And like anything in woodworking, protect your eyes, ears and lungs.

If you don't seal the end grain of your logs and timbers, they will crack and split as moisture is perspired. The end grain needs to be sealed up with a material that will close up the open pores of the wood. I often mix 50/50 wood glue and water then saturate the ends several times. You can also use paint or wax. These logs all started off at a pretty normal 32 percent moisture content.

Start off by air drying your wood for a few months to shed the first bit of water naturally, maybe a loss of eight to ten percent. Stack the wood up with plenty of spacers, or stickers, to allow for good airflow, and I like to put a piece of plastic on the ground under the wood to keep the humidity from the ground from effecting the lumber. I bind the wood with tie downs to minimize cracking and twisting, and I build a temporary plastic roof to keep off the rain. Place it in a location with good prevailing winds, it makes a big difference.

After a few months, bring the wood indoors and finish the drying. To build the kiln lay poly (clear plastic roll) on the ground and then build a frame with 2x4 studs on top of it for the lumber to rest on. Leave enough space to have a standard household dehumidifier at one end, and a small fan at the other. The fan circulates the air to even out the drying. I designed mine to pull air from below, then blow the air down a plastic tube to the other end. This way I know there's no stagnant air or dampness trapped in the kiln. This one is 20 feet, or 6 meters, long. The dehumidifier is also trapped inside the kiln and is set to maximum. This model has a hose that runs out of the kiln and fills a bucket. The kiln is built around the stacked and bound lumber over a light wooden frame that carries the plastic. All seams need to be sealed with vapour barrier tape to hold the moisture in. I cut a few small access holes to control the dehumidifier and to test the woods moisture content in various places. Tape up these holes after you use them. The wood remained in the kiln for about 4 months and reached an average of 8 percent. This is mostly 2" thick arbutus, also called madrone.

Using this unique wood often presents the opportunity to really showcase a unique piece of wood that you can be proud of harvesting in a sustainable manner. Thanks for taking the time to read through this instructable, now get out there and save some logs!

Im not sure how to ask this but I hope it make sense. What would be the best way to slice the log into slabs to prevent splitting and twisting? Is there a rule of thumb to follow? Im getting ready to process a winged elm. Thanks in advance.

The drawback of this method is the power consumption. Four months with a fan (say 35W) and dehumidifier (about 240W) is about 800 kWh, which would be a substantial addition to a power bill.Out of interest what was the ambient temperature? At low temperatures the rate of drying would be slow, while these dehumidifiers are usually designed to cut out at 32 C.

If I air-dry pine (Southern yellow pine) for 6 weeks with end coating and Borax and high strength termiticide and then 6 weeks with electric fan, will I get twisting in vertical beams sawn to 12" by 12" and 20 feet long? Could I use sooner than 12 weeks and put beam under light compression (vertical members) load? Tak

Hi, Would you mind giving me a little more of a "recipe" I suppose to your drying techniques? Im very new to this hobby and I want to make a table out of fresh cut hardwood. I also want it to be an outdoor table. Thanks for your time anyway.

not all sawyers know what they are doing. I asked for some quarter sawn oak and he started cutting parallel with the grain instead of perpendicular. He did not understand. I tried to correct him but the best part of the wood was ruined for quarter sawn. So have the confidence to double check and confirm that you are getting what you wanted. That means draw a picture on the log if that is what it takes.

I read that one of the important parts of kiln dried lumber is that it is heated to kill bugs. Should be heat the wood using a solar wall or something like that or would it dry out the wood to fast. I need to process red oak.

We made a large kiln for a Boy Scout camp using the body from an old dairy delivery truck. We air dry for about one month, then rack the wood in the kiln and use a dehumidifier and small fan. With the insulation, we can use the kiln in the winter (in Ohio) as the returned heat from the de-humidifier and the fan motor are sufficient, or we can add a small heater. The kiln is nearly air-tight and the de-humidifier drains through the floor. An alternative to a de-humidifier is a simple recycled window air conditioner where the cooled (dried) air is directed back through the compression coils and then out to the racked wood instead of exhausting the heated air outdoors. This arrangement should have a higher capacity than most de-humidifiers.

the fan is inside the plastic "room"( if you look close you can see the base of it in the pic) basically it just circulates the air inside the kiln, the plastic tube directs the damp air towards the dehumidifier without blowing over the lumber again. Be warned home dehumidifier are not designed for wood drying. The coils will slowly deteriorate from the acid in the wood. Coils in wood kilns are coated for protection. Coated with what?....I have yet to find out.

Just a thought but the coils might be helped by lightly spraying them with a rattle can of outside grade clearcoat. On the other hand you don't need to collect that acidic stuff. More humid air tends to rise so you could just blow the heated and dried air in from the bottom of the kiln and then top vent the acidic vapor straight out the nearest window.

Mark Twain (Samuel Clemens) once said, 'It took me 7 days to get over the worst cold I ever had, but with proper medicine and rest, I was able to get over the next one in only 1 week'. The humor being, it took about the same time either way. In the U.S. Southeast (summer temps around 100F in the day, always near saturation at 100-percent relative humidity), a couple of my friends and I built a simple three-walled 'pavilion' structure to put poplar 1-inch planks in to 'air-dry'. We cut, run 1/8-inch strippers between layers, thousands of board feet, and in about 5-6 months, we could take 35-40 percent green poplar down to 10-12 percent wood water by simply running a barn fan (42-inch diameter 1 hp motor) at the end of the pavilion, blowing through the planks. I'm still not sure of the exact mechanics of how this worked due to the high relative humidity, but with no monetary investment beyond building the pavilion and the electricity to run the fan (pennies a day per thousand board-ft), I can't look a 'gift-kiln' in the mouth.

You can build a re-saw for cheap to cut your logs into boards or planks. All you do is mount 2 tires on a frame. One stationary with a motor and the other needs to have an adjustment from side to side for the tracking. The only part that might cost is a 4 inch band saw blade. The whole set up works just like a belt sander.

how to kiln dry wood | cut the wood

You need to dry wood to perfection to improve its strength and to prevent mold attacks due to trapped moisture inside the wood grain. And when it comes to drying or seasoning wood, there are two ways to do it.

You can use the air-drying technique that lets wood pieces dry with the aid of sunshine and air. Wood is stacked and left to the elements and this can take months to completely dry. But for faster wood drying, most woodworkers rely on kilns.Kilns are similar to conventional ovens. These dry wood using hot air. Most kilns are wood-fired and are so effective that it can season wood to perfection in just a few weeks.Kiln drying basicsYou may either have a kiln at home or you can have your wood dried from a local sawmill with a kiln. But if you plan to start drying more wood to be used as construction material or for firewood soon then it would be a good idea to construct your own kiln at your property.Things you will needWood to be driedMoisture meterStickersTarpKilnInstructions1) Use a moisture meter to find out the moisture content of your woodSource: https://www.indiamart.com/proddetail/moisture-meter- .htmlThis will help establish a baseline value. A moisture meter is the most accurate test for determining a woods moisture content. It is a small handheld tool with two metal probes that are applied to wood. These probes read the moisture content of the surface as well as the internal part of the wood. The reading is expressed as the percentage of moisture according to the woods volume or weight.Use the moisture meter according to the manufacturers directions. The normal moisture content for wood used in woodworking projects is 6 or 7 percent. If you get a higher reading, it means that the wood needs to be dried and it is not ready to be used.2) Use stickers to dry the woodSource: https://homedesignersuite.co/quick-overview-of-home-designer-architectural-best-diy-home-design-software/Stickers are simply 1 x 2 (25 x 50 mm) pieces of lumber that are used to provide airflow between the boards you are drying. Lay each sticker about 16 inches (40 cm) apart and line them up parallel to each other. Youll need enough stickers to support the entire length of the boards you are drying.Stack the first layer of boards. Carefully set the first layer of wooden boards on top of the stickers, running them perpendicular to the stickers. Leave an inch or so of space between each board to allow for increased airflow.3) Preparing the kilnSource: https://www.pinterest.com/pin/42967 68/?lp=trueAllow the kiln to reach the ideal maximum temperature to dry wood. Close the kiln door to keep the temperature inside the chamber. Use a thermometer to find out the temperature inside the chamber.Once the kiln has reached the ideal temperature, place the wood one by one inside the kiln. If you have metal grates inside the kiln then you can arrange wood in such a way that no part of each wood touches the other pieces. This will greatly improve drying and will ensure that all the surfaces of the wood pieces are exposed to the hot air.Take care that your kiln does not run out of fuel so that it can maintain the temperature inside the chamber. Most kilns are wood-fired so be ready with a large stack of wood nearby just in case you need to refuel.4) Test the moisture level of your woodSource: https://wonderfulengineering.com/10-best-wood-moisture-meters/ Take two pieces of wood from the kiln and test it. If the results show high moisture levels, return the pieces inside the kiln and dry some more.5) Post kiln careSource: https://napoleonfireplaces.com/the-spectacular-science-of-stacking-firewood/ Once the wood is ready, remove it from the kiln and stack these in a neat pile. Use stickers (small pieces of wood) when you stack your newly dried wood. Place a row of stickers on top of the boards, lining these directly with the previous set of stickers.Continue alternating stickers and boards until youve stacked every piece of wood. You may store the wood inside your garage or tool shed but if you must let these remain outdoors, cover the drying wood with a tarp or other overhanging fabric.ConclusionKiln drying will be able to dry wood fast and in a more efficient manner. It can reduce drying times and can make wood ready for use in just weeks compared to months when you air dry. It would also be good to have a moisture meter whether you are air drying or kiln drying wood.

Freshly milled lumber requires about a year to dry and cure before you can use it in construction. Even firewood takes at least six months before its ready to burn. If your lumber needs are more consistent, a home firewood kiln can cut this wait time down to a week or less.[1] X Research source Solar kilns or smaller boiler-based models will be the most accessible for home users. Commercial kilns are very large and can cost thousands of dollars.

kiln dry wood at home: step-by-step method | garden tool expert

Kiln drying is an important practice that is required for wood production which serves to efficiently lower the moisture levels of green lumber to a workable-range moisture level that will not end up causing problems often associated with the presence of excess moisture in wood. Some of these include warping and cracking, binding, or kicking during machining, crowning, and other adhesive failures in the finished products. These moisture-related damages can cost millions of dollars in damages every year. The first step that would help bring wood products to moisture content levels that would be subjected to minimal moisture-related damage is kiln drying.

Now kiln drying your own wood at home can be very cost-effective, and youll be able to dry the wood to a moisture level that you prefer. It is also a sustainable way to harvest the materials around you, drying it fast enough for you to build woodwork with. If you make a piece of furniture with wood that is still wet, the finished product will continue to dry and eventually crack, and it may end up ruining the piece. Do you want to know how to kiln dry your own wood at home? This article will walk you through the step by step process of drying your lumber at home. Sit tight!

There are different resources available that offer plans for building a home-based kiln, and also provide greater details about the kiln operation as well as kiln-dried wood. In kiln drying, the lumber is usually stacked in a closed chamber where warm air is mechanically circulated. Here, the air circulation, temperature, and humidity is relatively controlled so that the moisture content is brought to a level where drying defects can be avoided. The moisture emitted during drying is drawn away, and this causes the process to speed up significantly. Kiln drying reduces the drying rate to about one week per 25mm which results in moisture content of just 8% 10%. However, this process should be carefully controlled to avoid placing undue stress on the substructure of the wood as it dries rapidly. If this occurs, the core of the timber can become very weak and it will not even be externally visible. That being said, here are the step-by-step methods of kiln drying wood at home:

The first step here is to mill your wood. Cut down the tree logs using professional chainsaws just like those used in sawmills, together with other necessary equipment in order to have wood of required size and shape. Also, proper sizing of the logs is a very important step in getting the woods to dry perfectly. The perfect time to cut the wood would be before winter to avoid humidity, and I would recommend that you do so in early summer or spring months. Depending on the log, you can even decide to mill it yourself using a chainsaw. However, if youll be doing this, ensure you follow the safety instructions highlighted in the users manual.

It is important to know that there is no accurate visual test for determining the moisture content of wood. However, to make sure your wood is at the perfect moisture level for woodworking, youll need a small tool called a moisture meter, which would help you determine the accurate moisture content of the wood. This tool usually features two metal probes that must be placed against the wood, and after a short time, it will display the actual moisture content of the wood. Typically, for most woodworking projects, the maximum acceptable moisture content is 7%. If the moisture content of the wood is higher than that, then it must be dried again to attain this level. To make things easier, you can seal up the end grains of the wood so as to close the open pores. You can also decide to wax or paint the pores in order to close them. If this isnt done to the end grain of your timbers, they will eventually crack and split up as moisture leaves the wood.

Once your lumber has reached the correct moisture content that is acceptable, the next thing is to equalize and condition it. Equalizing and conditioning (also known as stress relief) are two quality-control measures that are carried out to complete the drying process of high-quality hardwoods. Once they pass these measures, the woods are good to go.

Air drying simply means exposing your woods to natural air and sunlight to achieve drying. You can start by doing this for a few months in order to naturally get rid of the first bit of water (a loss of about eight to ten percent). This process is usually important and produces better results. There are some key factors to pay attention to when air drying. Ensure that you stack up the woods with lots of stickers or spacers under the natural air and sunlight, to allow for a good flow of air. The woods should never be used as a sitting place while theyre drying. The ground on which the woods are placed should not be humid to avoid negative effects on the lumber. The timbers should also be placed in a location with prevailing winds, as this would go a long way. You can also place some already dried wood such as some old 2 x 4s, and lay them out evenly with about 16 inches of space in between each of the stickers. These woods act as an elevated base, hence air can easily get to the wood from the ground, and the moisture from the ground does not make the wood even wetter.

After a few months of air-drying the woods, you can now bring them indoors to complete the drying. In order to do this, you will need to build the kiln. You will also need to construct the insulated kiln box by yourself. Here, two plans are involved; the first one involves using an insulated wooden frame, while the other involves using structural floor insulating panels. Building a kiln yourself not only reduces investment cost but also allows you to save enough when compared to other drying methods. To build the kiln, lay the clear plastic roll on the ground and build a wooden frame with 24 studs on top of it for the lumber to rest on. Remember to make space for a standard household dehumidifier at one end, and a small fan at the other for artificial airflow. This will help to dry the woods faster and better before the expected time.

The kiln is usually built around stacked and bound lumber, and over a light wooden frame that carries the clear plastic. All the seams must be sealed using a vapor barrier tape in order to effectively hold the moisture in. You may also decide to cut a few small access holes to control the dehumidifier and for testing the moisture content of the woods in various places. Always remember to tape up these holes after you use them to avoid exposure. The woods can remain in the kiln for as long as 4 months and would have reached an average moisture level of 8 percent.

Building your own kiln at home is very effective, and you can even make the arrangements on your own by using the dried woods in your woodworks. Finally, the kiln performance can be effectively monitored by taking kiln samples which should be selected from the kiln during stacking. The number of samples selected usually depends on the condition of the wood being dried as well as the drying characteristics. The type of kiln used is also taken into consideration.

By following these procedures, your wood should be ready for making the furniture that you desire. Using this unique wood often presents you with the opportunity to actually showcase that unique woodwork that you can be proud of harvesting in a sustainable manner.

Always remember that whatever you choose to do, ensure that the wood has a moisture content of less than 8% in it. In addition, it is important to always have a moisture meter to help determine the exact or correct moisture content. From when you mill the wood to the final finish, the woods moisture content must be accurately measured, not just in the kiln but also at each step on the way to its final use.

how to kiln dry wood - xinan wood drying kiln

Drying wood in large,Kiln drying removes more of the moisture than air-drying, thereby helping to reduce the chances of the wood splintering and warping. In addition, it ensures that there are no insects or mold existing inside of the wood. Kiln drying can be a costly process, and as a result, it is used most commonly to dry wood that will be used in building projects, although it is sometimes used to make firewood.

Collect the wood to be dried and check to ensure that it is all a uniform size. Woods in varying sizes will dry at different lengths, causing some to remain too moist and others to burn. In addition, check to see that the wood is not to long to fit inside of the kiln without making contact with the inside of the kiln. Cut the wood if necessary.

Lay small boards, known as stickers, overtop of the first layer of wood in order to allow air to flow over the exterior of the wood. The stickers should be placed flush with the end of each board in order to prevent warping.
