The term “hygroscopic” might seem hard to understand, yet, it simply means anything that absorbs and gives off moisture to reach equilibrium. Woodwork created from improperly dried wood may have compromised strength and these details durability. It can lead to warping, bulging, shrinking, and cracking, ruining the integrity and aesthetics of the finished product. In extreme cases, fungal growth and decay might occur, leading to structural failure.
When you have bought wood or if you have saw a log yourself into planks, you first need to know how much moisture is present in the wood. Only that way, you will know how long the wood will have to dry before you can use it as an essential part of your project. The two factors that dictate how much you need to wait for the wood learn here to dry are the atmospheric heat and the cause of wetness. Rain drenches wood, which increases the moisture content throughout the wood, even reaching its core. In contrast, a smaller water spill would just soak the surface and would require a shorter waiting period. Once the wood is dry, you need to remove it from the garage.
The goal of drying wood is to provide it with high strength. Low dryer temperatures and humidity can help increase strength. Besides, remember that fungal, bacterial, and other factors can lower strength, and they may be beyond your control.
Using a moisture meter to accurately measure the moisture content of the wood is also crucial, as improper moisture levels can lead to problems down the line. Kiln drying can dry lumber with a thickness of 25 mm in about 10 hours to a moisture content of 18%. However, if you want to achieve a moisture level of 8%, it may take up to 28 days. So, understanding the drying process and selecting the right method is crucial for successful woodworking projects. The fastest way to dry wood for woodworking is by using a kiln with high temperature and high airspeed. This can dry lumber with a thickness of 25 mm in about 10 hours to a moisture content of 18%.
That is why it is very important to pay special attention on how to dry wood. It will be good to note likewise that solar kilns do not necessitate stress relief because the high humidity of the night can relieve the lumber from casehardening. As a rule, the final MC of the wood in the kiln must be within 2% MC relative to the expected EMC of wood in use. Follow this rule to prevent manufacturing losses and loss of customers and sales.
Since a flat sheet goes over each layer of spaced logs, the next layer of logs on top sell can be off by one log, so there is empty space beneath and above each log or beam.
