Logging Operations

MCWP manages logging crews and contracts through outside logging contractors.  Every logging job is under legal contract with the land owner.  Logs are harvested in tree length from lands we own and manage as well as contracted timber sales. Our logging equipment is maintained to promote safe, efficient, and environmentally friendly working conditions. In the past few years we have made some significant upgrades to our logging equipment. Our newest equipment automates much of the logging process.  The newer technology gives us constant wireless access to the equipment providing us with up to date production and operation details. Our goal is to limit the use of chainsaws in the logging process, keeping our workers in a much safer environment. Feller bunchers and delimbers are used in the woods along with skidders to drag trees to a landing.  At the landing they are loaded with knuckleboom loaders onto log-trucks and delivered to the sawmill site.

Logs coming from the woods to the mill are weighted or hand scaled to estimate the maximum Board Footage. We unload by overhead crane onto the sawmill log yard.  The capacity of the sawmill log yard is 4 million plus board feet.  When weather conditions are favorable additional logs are sent to our overflow yard.  The capacity of this yard is 2 million plus board feet.  This surplus of logs insures that our sawmill will have logs even when logging conditions are not favorable. 

Milling Operation

Logs are loaded by the crane from the sawmill log yard onto a log deck that advances the tree length log, one at a time, to the log merchandising line.  The merchandising line operator and crane operator work together to make sure the correct diameter logs are on the deck for maximum usage during the sawmilling process.  After being merchandised the logs go to either the scragg mill or grade mill.

Smaller diameter logs go to the scragg mill and the larger diameter logs go to the grade mill. Prior to reaching these mills, the cut to length logs go through a ring debarker, removing the bark from the log. The bark goes through a hog and is ground finer to be used and sold as landscape mulch. Excess material is chipped and sold as paper quality chips.  The sawdust is sold into markets that include boiler fuel, wood pellets, and carbonization.  We also use our sawdust to fuel a boiler which supplies heat for our pallet heat treating and drying system.

Cooper Scragg Mill

After the merchandising line the smaller logs are cut to length, on a multi-head trim saw, based on sizes needed to satisfy pallet orders.  The logs then proceed to the sharp chain scragg mill where they are slabbed and squared.  The rounded slabs go through a Cooper slab edger for a 4” width, and proceed through a 2 head West Plains Horizontal band saw for board thickness.  The center squares are then cut at 4” to 8” widths on a Cooper scragg edger and then proceed through a West Plains multiple head band saw to cut to thickness.  Material then proceeds to a chain conveyor where board quality is inspected and recorded.  After inspection the boards are stacked automatically on a AIT board stacker.  This Cooper double scragg mill produces 60 thousand board feet of hardwood daily or up to 100 thousand board feet of pine daily.

Grade Mill

After the merchandising line the larger logs are loaded onto a carriage that feeds our 7 foot band headrig where 3D scanning technology is used to insure maximum grade and yield is obtained.  All lumber is edged and double end trimmed to remove wane and defect.  For maximum production, the centers of the logs are sent to a 6 foot linebar resaw for final breakdown: grade lumber, railroad ties, and cants end up on a sort line.  There they are graded by a National Hardwood Lumber Association certified grader, sorted by grade, species, and length then stacked for shipping or further processing. Our grade mill operation cuts 35 thousand board feet of lumber on a daily basis.

Heat Treating

Heat treating is a process that heats the core of the wood to 133 degrees for 30 minutes. This is done to kill insects and pests that might be in the wood. This process is important for customers requiring pallets or lumber that will be shipped to other countries.  This is a third party audit process that follows ISPM15 standards.

Pallet Drying

When customers require pallets with low moisture content we can dry pallets using a standard air drying process or by drying in our heat chamber allowing the wood to dry to a moisture level at or below 20%.
