That's why there are a few rules to follow.<\/p>\n
- \n
- The trunk should be made into planks as soon as possible after the tree has been felled. The thickness of the plank is variable and depends on what is to be obtained from it.<\/li>\n
- Keep in mind that as the board dries, the size of the plank decreases. Cut the planks slightly larger than the size you need.<\/li>\n<\/ul>\n

- To prevent cracking, the ends of the plank are sealed with paraffin, special oils or diluted primer. This will slow the moisture out of the wood and reduce the risk of cracking.<\/li>\n<\/ul>\n

- Depending on the time of felling, the humidity inside the tree can reach up to 200% (spring). It must be removed slowly to avoid tension inside the wood. It is recommended to cut during the dormant period (November-January) because the amount of water in the tree is the lowest.<\/li>\n
- The bark does not peel off during drying. It acts as an insulator, slowing the outflow of moisture and reducing stresses.<\/li>\n
- If there are insect or mold infested areas, they should be removed so as not to contaminate the rest of the wood.<\/li>\n
- The boards are stacked 30-40 cm from the ground. Wooden slats of 8\/10 or 10\/10 mm are placed between the planks, perpendicular to the plank. These allow air to circulate around each plank. A fairly heavy weight (100-200 kg) is placed on the stack so that the wood does not warp during the drying period.<\/li>\n<\/ul>\n

- It is recommended that stacking is done in a shelter, under a shed or even in a barn. The cellar can also be used, as it has constant temperature and humidity. Ventilation is very important to promote drying. A fan can be used to increase air movement. If there is no possibility of sheltering the stack, it should be covered (with sheeting, Plexiglas or other materials that can protect it).<\/li>\n<\/ul>\n

- Natural drying of the wood takes place slowly and depends on the thickness of the plank. One year is needed for every 1 inch (2.5 cm) of thickness. Some experts say one year for every inch plus one year. That means a 2 inch plank needs 2+1=3 years, a 3 inch plank 3+1=4 years and so on.<\/li>\n
- The natural drying process stops when the wood has reached equilibrium. The equilibrium humidity depends on the ambient humidity. Here, the equilibrium humidity is around 12%. If the humidity is to be lowered below this value, the wood needs to be taken to a heated room.<\/li>\n
- The equilibrium moisture content is determined by measuring the internal moisture content of the lumber. It is reached when several consecutive measurements show the same value.<\/li>\n<\/ul>\n

- To achieve good results in natural drying of hardwoods, do not cut young trees, avoid knots as much as possible, and make sure that the wood has no growth defects.<\/li>\n<\/ul>\n
I am convinced that following these recommendations will result in very good quality timber.<\/p>\n
Of course, there is also the possibility that forced drying<\/a>in special dryers. In this case the drying time is significantly reduced.<\/p>\n
