How timber is processed?
Trees are cut down in the forest and then transported by truck to a timber saw mill where the trees are debarked (bark stripped off) and cut up into smaller pieces. Sometimes this is all done in the forest or plantation.
Should you let logs dry before milling?
Summary: Logs should be milled for drying as soon as possible, and the ends should be sealed as soon as they are felled. A bandsaw mill will create less waste than a chainsaw mill. Logs can be sawn for grade, quarter sawn, or flitch cut.
How does a sawmill work and what does it do?
A sawmill’s basic operation is much like those of hundreds of years ago; a log enters on one end and dimensional lumber exits on the other end. After trees are selected for harvest, the next step in logging is felling the trees, and bucking them to length. Branches are cut off the trunk.
How are trees cut down for a sawmill?
Trees are cut down using chainsaws during the logging process. This step is known as felling. Felling is essentially cutting down the tree and cutting it to length. Then, the log is delimbed and loaded on a truck for transportation to the mill.

Where was the first sawmill in the world?
The first known sawmill dates back 400,000 years to Nice, France, where archaeologists discovered a wooden hut built with processed logs. By 500 B.C., men used bronze axes, saws and chisels to mill rough lumber for wood homes and forts.
