A sawmill works by cutting logs into lumber using large bandsaw blades. The same process is repeated over and over, log by log, to produce high-volumes of rough cut lumber. This process will vary slightly from sawmill to sawmill.
How long does the sawmill process take?
As a very rough estimate, a 12″ diameter 8 foot long log will take around 25 minutes; an 18″ diameter 8′ long log will take around 40 minutes to saw; 24″ diameter will be at least 1 hour.
What to expect working at a sawmill?
Sawmill Worker Job Description Example/Template Sort and arrange logs and timber according to sizes and wood type to allow for easy identification. Roll logs from deck onto roller tables to transport to sawing machines for cutting. Guide log position on carriage to ensure cutting is precise and according to standards.
How are sawmill powered?
Decades ago, most sawmills used steam power, so they required a dependable and renewable water source. They also added value by using water as a log transportation tool and stored logs in rivers or lakes to prevent stored wood from drying out. Today, steam power is gone, but land is in high demand.
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 long should logs dry before milling?

How did lumber and grain mills get their power to run?
They dammed streams and rivers to power the mills that were essential to those early, self-sufficient communities. The flowing water sawed their lumber and ground their grain, and, once the land had been cleared for farming, even kept their milk and cheese cool in hot weather.

Storing logs under sprinklers or in a log pond helps prevent end checking and slows deterioration caused by insects, fungal stain, and decay. However, chemical staining can occur under wet conditions.
Can you mill fresh wood?
Re: Using green wood If it is left open, i.e. not being sheathed over both sides so it can dry in place, it will be fine. There are days when I might need a few boards for a shed or whatever outbuilding, I’ll throw a log on the mill and saw them, and then nail them right up.
Is it better to cut wood wet or dry?
Wet Wood Vs Dry Wood But wet wood is actually much easier to cut than dry wood. With dry wood lacking moisture content, more friction is created as the chainsaw chain comes into contact with the wood fibers. This friction results in the chain slowing down.
Can you kiln dry whole logs?
Using a conventional kiln, the logs or timbers are dried to a consistent moisture content all the way through. This process takes about 2-3 times as long as ALS. Having logs and timbers that are fully dried minimizes any future movement of the wood.
