Handyman Guide > Building Materials: Choosing Lumber
Just as it is important to select the right tool for a job, so is it equally important to use the right kind of materials. A simple illustration of the wrong selection of material is the use of a nail rather than a screw to fasten a door hinge. The nail can be driven in quicker, but it will soon become loose and the entire job will have to be done over again and the damage repaired.
If you are not sure of what materials to use, go to your hardware or paint store, or to a lumber yard. Here you will generally get sound and valuable advice, for any business interested in preserving its good name will recommend only the best. This advice should always be sought when planning a major project, such as building a garage, where the cost of the materials required is considerable. Far too many home-construction jobs have failed because the wrong size of lumber was used or the nails were too short.
It is wise to be skeptical of any "cure-all" products unless recommended by a reliable person who has reason to know their value. There are a great many products on the market which are far superior to the older types, but there are just as many worthless ones which cost the home mechanic much in time and money. The old way is not always the quickest, but very often it is the best.
Do not cheat yourself by buying poor quality materials. If you are going to do the job yourself, you will save considerable money in labor cost, and a portion of this saving should be used in buying the best materials.
LUMBER
Lumber yards stock wood in two forms, rough and surfaced. Rough lumber is in the form in which it comes from the sawmill. The edges may not be square, and the surface is rough and shows saw marks. Surfaced lumber is planed on two or more sides and has square edges. Lumber is measured in the rough state, and surfaced lumber, therefore, will measure slightly less, due to the planing. In most cases, the surfaced lumber will be about one quarter of an inch under the rough. Thus, a piece of 2 x 4 inch stock will be about 1 5/8 by 3 5/8 inches :when surfaced on all sides.
The home mechanic will find surfaced lumber best for practically every purpose. It is much easier to work with, particularly when all sides are square. The planing required to make surfaced lumber out of rough takes only a short time with the machine used in a lumber yard, but it would entail hours of hard work with a hand plane, with results always imperfect. The diffcrence in cost between rough and surfaced lumber is not enough to warrant the extra work.
