Twist - Do not use Twisted lumber. He will always lead to the final piece of Twisted. Checking twist, putting a piece of wood at the same level (horizontal) surface. Use a short level (often called the level of "Torpedo"), to determine the twist. Check both ends of government, if the level of said the same on both ends of the piece is not twisted. If the product is strongly deformed, you can see it, depending on the length of the board.

Humidity - All wood contains moisture, even after the "dried". Make sure that the timber has a stable humidity. Standard Grade lumber, usually in the high humidity and other faults. You can dry wood by placing it with an air gap between all the surfaces. Reiki is used for this purpose. Be sure that air can get to the bottom of the stack. As a rule, I stack wood bed for 4 "x4" 'S, and then use the strips between each layer, as well as leaving 1/2 open space between the boards.

Stack your wood in a dry place, in the sun, and give him enough time to dry. You can buy a hygrometer to read moisture content (not required) 5% to 10% moisture. 1 "thick forest to dry 1 to 3 months, and 2" thick wood takes from 2 to 6 months. If you're buying premium wood, it will be at least partially dry. Your provider checks the moisture content.

As wood dries, the tree fault appears, so council, which looks good, perhaps completely unusable, as dries.

Crown: Crown of wine that can be easily seen by looking down on the edge of the board or laying a straight edge or string line along the side. This error can not be removed or planning saw the head, but, of course, you lose part of the council. When using hardwood furniture removing the crown is just part of this process.

Onions: Onions wine that is easy to see. Put the board on a flat surface, as if bowed, it will rock. Onions are usually removed without much difficulty, if you have the attachment points, however, to avoid fees, which obviously bowed.

Cup: a cup of wine, where the edges curl board. Gently folded card usually pull down, when at anchor in another piece of wood. Push down on the outer edges of the board. If you can easily press council flat (a plane), you can use the advice. If you use a board that too much of a cup, it will be a split in the middle as you pull out of the cup.

Shake: Shake is a fault that occurs in the forest as the tree grows. He points out that the tree grows in conditions of stress and, as a rule of hearts are open splits. Shake usually leads to a rotation and should be avoided. Roth: rotten wood is discolored and soft. You can use a significant portion of rotten boards, otherwise avoid rot.

Loose / Missing site: bunches can be glued back and missing in the node can be filled. I like to use the finite size of the holes and knot transplantation slice in the council. Of course, this process takes time, so judge accordingly.
