![]() The resaw uses multiple bandsaw or gang saw blades to cut the log into the boards that were merchandised in step 5. Step 7 - Resawing - Cants that enter the resawing stage are usually being milled into rough cut lumber. Pallet manufacturers often do this since the pallet sizes are built custom based on the dimensions of the product it's being used for. If the size of the lumber needed is unknown, the business will likely buy cants and cut them to size. The logs can be sold as cants with only one size milled, but this isn't normally the case. Step 6 - Canting the Logs - The head rig cuts the log into cants, which are essentially logs that are flat on at least one side. Logs enter the head rig saw by getting clamped on a conveyor belt where the head rig blades move through the log. Step 6 - Head Rig Sawing - When you think of a sawmill, you likely picture the head rig. Over the course of days and weeks, this can make mill more profitable by eliminating unnecessary waste on every log that's cut into lumber. Lasers can be used to estimate the log so the mill can maximize the lumber it gets from each and every log. Step 5 - Merchandising the Log - Merchandising in the modern age has made sawmills much more efficient. For the logs that have metal in them, the metal will either be removed or the log will be cut into smaller sections so as much as possible can be salvaged. Often you will find nails, wire fencing, or other metals in the logs which can ruin your sawmill blades if they're not caught beforehand. Since trees can live for hundreds of years, there's no saying what could be found in them. Step 4 - Metal Detection - Each log will go through a large metal detector before being cut. The bark is then saved as it can be sold as mulch or used to fuel certain kilns at a sawmill. A debarking machine is used to strip the log of its bark. Step 3 - Debarking The Log - Once the log gets to the front of the conveyor belt, it will enter the mill to be debarked. Step 2 - The Log Enters The Sawmill - Next, the log is moved using piece of heavy machinery and put on a belt where it awaits its turn to be cut. Once at the mill, the logs are unloaded and stacked into piles where they wait to be cut. Then, the log is delimbed and loaded on a truck for transportation to the mill. Felling is essentially cutting down the tree and cutting it to length. Trees are cut down using chainsaws during the logging process. Step 1 - Logging & Transportation - Timber harvesting, or logging, is the first step to getting a log to the sawmill. The process of lumber milling actually starts long before the log ever reaches the mill. I hope you guys enjoyed that and stay tuned for more videos. (3:58-4:08) Well, that about sums up how a log is turned into lumber. (3:50-3:58) After the boards have been graded, they are sorted and stacked and ready to go to our customers. Then the boards are taken to the next step to be graded and finally sorted into the stacks. He's using a laser to make sure they're the right width. (2:49-3:50) ow that the log has been squared off, you'll see another operator finally cutting it into boards. He's squaring off the logs so they can then be cut into boards. We'll fast forward a little bit, but you get the idea. As you can see the operator is squaring off the logs. (1:51-2:48) Here is a ground view of what you were just watching. (1:06-1:50) Here you'll see a log enter the debarker and it comes out the other side with the bark removed and ready for the next step. (0:41-1:05) Next, logs are loaded into the debarker so the bark can be removed and turned into mulch. (0:29-0:40) Each log is then scaled and sorted by species. (0:19-0:28) After the logs have been unloaded from the trucks, they are cut to the desired lengths. We buy both standing timber as well as Gatewood which other people bring to our sawmill. (0:09-0:18) The first step is for logs to be delivered to the mill. ![]() (0:00-0:08) This is a video from Beiler's Sawmill and today we will be discussing how a log is turned into lumber.
