BUYING TIMBER

Inexperienced timber buyers often purchase incorrect quantities because of confusion about the measurements. When buying a piece if dressed timber, you’ll find that its actual dimensions are a bit smaller than those specified. That’s because timber is sold by “nominal size”—the size it is when it’s cut at the sawmill. After planing and shrinkage, the actual size is a bit smaller. Make a chart of the following comparative dimensions and keep it tacked to your workshop wall.

By the length

Timber is usually sold in standard length, which range from 0.9m to 6m, in increments of 300mm. When large quantities are ordered, it is generally supplied in random lengths that add up to the total number of meters ordered. Timber can be bought cut to length, but you will be charged for the piece it was cut from—a piece measuring 2145mm will cost the same as the standard 2400mm length. Price is usually quoted in lineal meters, according to dimensions. Timber is also sold in cubic meters, but it is unlikely that any domestic job will call for such a large quantity.

 

IS IT STRAIGHT?

As timber dries, the outside part of the original log tends to dry faster, and the timber will cup. To detect any warping, sight along the length of the plank. Some slight cupping is common, but reject any plank with pronounced warping. Also check timber for cracks, stains and other damage.
