The objective of selecting your wood is really you finish up with a decent final product. While all wood typically has flaws, you need to select wood that’s reasonably fault free.

Problems and Flaws to prevent include:

1) Twist – Don’t use twisted lumber. It’ll always create a twisted final piece. Look for twist by lounging the wood on an amount (horizontal) surface. Make use of a short level (frequently known as a torpedo level) to find out twist. Check both sides from the board when the level reads exactly the same on ends, the piece isn’t twisted. When the piece is extremely twisted, you can observe this by searching along the size of the board.

2) Moisture – All wood contains moisture, despite being “dried”. Make sure your wood includes a stable moisture content. Standard grade lumber is usually full of moisture along with other flaws. You are able to dry your wood by stacking it with air spaces between all surfaces. Laths can be used for this purpose. Make sure that air can arrive at the bottom from the stack. Typically, I stack my bunk of wood on 4″x4″‘s, after which use lath between every layer, also departing 1/2″ open space between boards.

Stack your wood inside a dry area, from the sun, and provide it sufficient time to dry. You can purchase a moisture meter to see the moisture content (not essential) 5% to 10% is dry. 1″ Thick wood will dry in one to three several weeks, while 2″ thick wood takes 2 to six several weeks. If you purchase reasonably limited grade wood, it will likely be a minimum of partly dry. Have your supplier look into the moisture content.

As wood dries, wood problems appear, so a board that appears good may completely become useless because it dries.

Crown: Crown is really a fault that may be easily seen by searching lower the advantage from the board or by lounging an upright edge or string line across the board. This fault can be taken off by planeing or saw the crown out, however, you loose part of the board. When working hardwoods, removing crown is simply area of the process.

Bow: Bow is really a fault that’s easily seen. Lay the board on the flat working surface if bowed, it’ll rock. Bow is generally removed with little difficulty for those who have points of attachment however avoid boards which are clearly bowed.

Cup: Cup is really a fault in which the edges from the board relax. Mildly cupped boards will often pull lower when moored to a different wood. Push lower around the outer edges from the board. If you’re able to easily push the board flat (right into a plane), you should use the board. If you are using a board which has an excessive amount of cup, it’ll split in the centre while you pull the cup out.

Shake: Shake is really a fault occurring within the wood because the tree grows. It signifies the tree keeps growing under stress and frequently the center area splits open. Shake usually leads to twist and really should be prevented.

Rot: Rotten wood is discolored and soft. You can utilize the great part of a rotten board, otherwise avoid rot.
