Wood Planing  

Timber and lumber seasoning is the process of drying out lumber or timbers and is essential for all types of wood. Seasoning refers to the process of drying the wood slowly to keep it from warping and cracking. The two main methods of seasoning lumber and timbers are to air-dry them or to dry them in a kiln. It is important for wood to be dried as the sap it contains is food for various types of parasites and fungi. Drying is therefore an essential part of making sure that it lasts for a long time.

Lumber Seasoning

The air drying method of seasoning involves stacking the wood in a covered area outdoors. The wood that is being seasoned is stacked with the use of spacers that allow air to pass between the timbers, thus speeding the drying process. Lumber that is being kiln dried is stacked within a controlled environment where the air is circulated around and between the timber pieces by artificial means such as fans. The air in the kiln is heated and the temperature is controlled. In some cases, the humidity may also be controlled with the use of steam jets. There are different methods of finishing lumber after seasoning; in some cases it will be sold in its rough form, in others it will be planed smooth before being sold. Finally, it will be bundled with other pieces of the same grade of timber to be taken to a lumberyard and from there it will be sold to consumers. 

  Wood Veneer
  The process of paneling allows the lumber industry to make use of otherwise unusable scraps and leftover pieces of wood. The paneling process produces such materials as veneer, plywood and particle board. To create veneer, a log is spun using a lathe while a knife shaves it into a thin sheet. Plywood is produced by taking several veneer sheets and sticking them together with adhesive. Particle board is made by combining smaller fragments of wood with resin and wax and compressing the mixture as it dries to form a sheet of material. This material is widely used in making furniture.
