Smart Log Processing

For more than 30 years, Wood-Mizer has developed a strong reputation as the leading manufacturer of portable sawmills, industrial sawmills and complete log processing systems. Wood-Mizer’s Smart Log Processing Line (SLP) has taken thin-kerf, low waste concepts into an industrial environment and positioned the company as the preferred choice for maximizing higher log yields at lower operating costs from small and medium sized logs.

Wood-Mizer's Smart Log Processing line has been installed in hundreds of locations around the world.

Continuing the success of Wood-Mizer’s patented narrow band technology, the SLP is a flexible series of modular products designed for the profitable conversion of 4” to 16” diameter logs into boards, battens, and pallet wood. Although there are many configurations and setups, a typical layout consists of one or more TVS units (Twin Vertical Saw), SVS units (Single Vertical Saw) or SHS units (Single Horizontal Saw), Horizontal Resaw and an EG300 Multi-Rip Edger. The system can be set up in a conventional, in-line arrangement for maximum efficiency, or it can be setup modularly for convenience. Based on standard cutting units and combinations of chain, belt and roller conveyors, the SLP system can be customized to fit any operation. With hundreds of individual units and systems operating worldwide, the SLP line sets the global standard for processing small and medium logs for profit.

The compact and low cost TVS (twin vertical saw) removes two sides off a
log before it is sent to the SVS (single vertical saw).

One company profiting from Wood-Mizer’s SLP line is S&J Contracts in Northern Ireland.  Led by Stephen Sufferin, the company produces pallets and specialized timber by utilizing Wood-Mizer’s thin-kerf technology. “In 2007 we had difficulty sourcing locally sawn pallet wood, so diversification was in order. We decided to mill our own timber to guarantee supply and cut production costs,” said Stephen. S&J Contracts’ SLP line, similar to a U.S. scrag mill pallet operation, consists of the TVS, SVS, a four-head Horizontal Resaw, material handling for loading and transferring, and a Multi-Rip Edger.

The way the SLP line works is simple: The TVS features two tilted heads and removes the slab from two sides of the log. The SVS shares the same titled head design and splits or removes the third side from the two-sided cant coming from the TVS. From there, the Horizontal Resaw recovers as many boards as possible. Lastly, the Multi-Rip Edger standardizes up to three board sizes for maximum sawn timber recovery. The Wood-Mizer SLP line can be easily reconfigured for maximum flexibility and is well suited for new ventures and diversification of existing mills. New ventures can take advantage of the lower capital required to install and maintain the line while existing mills can reevaluate how to better utilize lower-value logs by increasing yield and capacity to efficiently match market demand.

Stephen acknowledges that adaptability is the key to being successful in the industry. “We have enough timber to go on with our normal jobs without relying on sawn timber suppliers,” said Stephen.  “The mill is flexible. I make my money from the various sizes of timber I am asked to produce.”  Stephen believes that a major factor contributing to the success of S&J Contracts has been the investment in the best quality machinery for the job.

Darryl Floyd, Wood-Mizer’s COO says, “We designed the SLP system as an answer for sawyers who are

looking to maximize their sawing capabilities when it comes to sawing small logs. We recognized the need for scragg mill operations in the marketplace and the SLP system is our solution. Companies all over the world are squeezing every last board out of small logs and profiting in this tough and competitive environment.”

With hundreds of units sold across Europe, Asia and Africa, and with the installation of this equipment in locations across North and South America, Ireland’s S&J Contracts isn’t the only company to benefit from Wood-Mizer’s versatile SLP line. Wood-Mizer has companies in Mexico, Guatemala, and Chile which have recently installed the SLP line and are successfully sawing small and medium sized logs for profit, establishing the system as a proven performer in the global economy.

Growing with Wood-Mizer

After 20 years in the business, Darrell Gruver, owner of D&D Logging and
D&D Hardwood LLC, still enjoys grading logs.

For nearly two decades, Darrell Gruver has built and grown his two businesses, D&D Logging and D&D Hardwood LLC, with a knack for identifying problems as opportunities and a Wood-Mizer sawmill. Over the course of 18 years, Darrell has owned five Wood-Mizer industrial headrigs, three Wood-Mizer portable hydraulic sawmills and is currently installing three Wood-Mizer WM4000 industrial headrigs to become the centerpiece of D&D Hardwood LLC.

Starting out as a logger in the late 1980s, Darrell established the family-owned and operated D&D Logging in Racine, Missouri. He quickly realized that he could do better for both himself and his customers by utilizing extra value from the logs he was handling. He discovered that all it took was a willingness to sort and haul better quality logs to a grade lumber mill rather than to their original destination of being converted into railroad ties or pallet lumber.

After running D&D Logging successfully this way for several years, potential catastrophe became opportunity in the mid-1990s when the owner of the sawmill where Darrell sold most of his grade logs informed him of plans to retire. Faced with the loss of this business, Darrell reasoned that having a mill of his own would decrease transportation costs and provide needed diversity to his operation.

D&D Logging and D&D Hardwood LLC in Racine, MO.

In 1996, Darrell encouraged his father-in-law, C.R. Smith, to purchase a Wood-Mizer LT40 Hydraulic sawmill and enter the milling business. For the next year, C.R. sawed logs into grade lumber in a pole barn near Darrell’s home with the diesel powered thin-kerf LT40 Hydraulic bandsaw. When C.R. decided to move on, Darrell purchased the mill himself and established D&D Hardwood LLC to supplement his growing logging business.

After six years and 9,000 hours on the LT40 Hydraulic, Darrell was pleased with Wood-Mizer’s service, production capacity and durability and decided to upgrade to the LT70 Hydraulic –Wood-Mizer’s most productive thin-kerf sawmill at the time. Shortly after the purchase, Darrell’s son Anthony became interested in the business and focused on running the sawmill, which gave Darrell time to concentrate on improving his logging operation.

Sawn and edged grade lumber.

Less than a year later, Darrell soon found D&D running out of sawmill capacity with the growth he had experienced with his logging business. He decided to expand into a full production sawmill capable of producing several million board feet of grade lumber per year and built an operation centered on a Wood-Mizer LT300 industrial headrig. “I had become a Wood-Mizer fan,” he said.

In 2006, production increased with the addition of two more Wood-Mizer LT300s, one to upgrade the LT70 and the second installed to act as a resaw to increase production. At this point, Darrell estimated that the three LT300 headrigs combined to saw lumber at a rate of 6,000 board feet of grade walnut lumber per hour. With high production rates and an efficient operation, D&D yet again continued to expand and just four years later, Darrell upgraded and installed two WM3500 industrial headrigs. “The machines are very reliable and the service from Wood-Mizer is unsurpassed,” Darrell said. “Choosing Wood-Mizer was an easy decision.”

D&D's WM3500s cut more than 140,000 board feet of walnut weekly.

Darrell says that using thin-kerf bandsaws not only increases the productivity of his business, but reduces the number of trees that need to be harvested. “We try to get the best lumber out of every log,” he said. “Thinner kerfs mean less sawdust and less sawdust means more boards. That’s good for the pocketbook and for the environment.” In the current operation, fitted with a Wood-Mizer LT300 headrig, two WM3500 headrigs, an LT40 HD, HR1000 industrial resaw, and two industrial edgers, D&D is producing around 200,000 board feet of hardwoods per week.

On a typical day, oak, walnut, cherry and maple logs between six and fourteen feet arrive at D&D Hardwoods where they are scaled, graded and sorted. The logs are then sent to one of three headrigs depending on wood species and all of the grade lumber is removed. When sawing species other than walnut, a residual pallet cant or railroad tie is produced. Boards and cants are edged to obtain the highest possible grade and sent to the HR1000 resaw to reduce further processing. “From start to finish our operation strives to not only get the most out of every log, but to do so in environmentally sound ways,” said Darrell. “Depending on the customer’s needs, we almost always selectively cut in ways that will be the best for a sustainable forest.”

Today, Darrell is in the process of installing three Wood-Mizer WM4000s to increase productivity and improve consistency across the business. Complete with high tech computer automation controls, servo motors in the head, and 50% more steel than the WM3500, the WM4000 is designed for production and built to last. “These saws are very efficient, fast and powerful,” said Darrell’s son Anthony who has been operating Wood-Mizer mills for more than a decade. “The thin blades require less power than other saws and the setworks make them a ‘no-brainer’ to run.” As the market expands, Darrell’s proven business model and forward thinking approach has positioned D&D for continued growth and success in the lumber industry.

Family Sawmill Business Boosts Production with Wood-Mizer WM4000

Mike and Shawn, Honey Grove Hardwoods LLC owners, with their Wood-Mizer WM4000 industrial headrig

In less than three months after taking ownership of the family sawmill business, 3rd generation owner Mike Junk and his brother-in-law Shawn Fowler made the changes necessary to compete and thrive in the lumber industry. By installing a Wood-Mizer WM4000 thin-kerf industrial headrig to replace their old circular sawmill, Mike and Shawn positioned Honey Grove Hardwoods LLC on the cutting edge of technology to increase efficiency, yield and profits for their business.

Producing grade lumber for moulding, stair treads and flooring, the Pennsylvania based Honey Grove Hardwoods used a circular sawmill as the center of their operation for more than 70 years. Last year, Mike and Shawn came to the conclusion that their circular saw with conventional wide kerf blades had reached the end of the line. “We realized we were running outdated equipment when we weren’t getting the footage and grade yields that we thought we could get with thin-kerf technology,” Mike said.

Mike also noted that their operation with the circular sawmill forced the sawyer to do multiple jobs at once. “A vertical edger was positioned in front of the sawyer booth on our circular headrig, which meant the sawyer was also the one doing the edging,” Mike said. He explained that this process helped with saving costs on labor, but since the sawyer was rushed to saw as well as edge the lumber, it sacrificed quality and production.

Transferring lumber to the
Three-Way Conveyor

Wanting to improve efficiency throughout their operation, Honey Grove Hardwoods added a Wood-Mizer Log Deck, Three-Way Conveyor, and Green Chain along with an EG400 edger to complement the WM4000 in their production line. “We put the whole Wood-Mizer system in starting with the Log Deck, which helps ease loading logs onto the WM4000. From there, logs are cut on the headrig and then moved from the built-in conveyor to the Three-Way Conveyor,” Mike said. “Material is transferred from the conveyor to the Green Chain and then to the EG400 edger for a very smooth transition from logs to accurate lumber.” With this system, the sawyer no longer has to be the edger, which improves efficiency and quality of materials.

Feeding boards into the EG400

Compared to their old circular sawmill operation, Mike said their yield has improved greatly with Wood-Mizer equipment. “The yield factor is amazing with thin-kerf producing only one-third the waste of our circle sawmill, plus you can slab smaller and lighter which increases usable lumber,” he said. Being able to produce more product from fewer logs also cuts down on transportation costs and increases the profit per log. “We are getting the same amount of lumber while using 25% less timber and raw materials, which in turn, reduces transportation costs across the board,” Mike said.

By taking advantage of Wood-Mizer thin-kerf technology, Mike and Shawn have positioned Honey Grove Hardwoods LLC to be competitive in the lumber industry for generations to come. “The WM4000 put us right back up to the competitive edge on utilizing and maximizing yields for our business,” Mike said.

Massive Wood-Mizer Sawmill provides new Profits for Portland Hardwood Supplier

Meet Art Blumenkron. This forward-thinking, eco-minded owner of Goby Walnut & Western Hardwoods has recently installed an extra-sized thin-kerf Wood-Mizer sawmill to maximize profits for his business and minimize his impact on the environment.

The Pacific Northwest is well known for its towering tracts of evergreen forests. One Oregon company, however, is making a name for itself by tapping into the wooden treasures found within a different natural resource: dead, dying, and diseased hardwoods. Goby Walnut &Western Hardwoods is seeing worldwide sales due to their impressive product offering, and is leading the way in using environmentally responsible & profit enhancing business practices.

Started over 35 years ago by Gary Goby, the company was purchased in 2007 by Art Blumenkron, an entrepreneur who was looking for a break from the high stress of his dental equipment manufacturing business.  He was ready to invest his time and money into something more rewarding. That’s when he discovered Goby Walnut, being run from Gary Goby’s home outside of Albany, Oregon.

A large Walnut slab, up to 75" wide, in inventory

Art realized that the growing specialty hardwood supply company had untapped potential, and after making the purchase, he moved the company to the Northwest Industrial area of Portland, hired additional employees, and invested in a professional website displaying their inventory of hardwood slabs, figured boards, tone wood billets  and veneers. Art’s changes are having their intended effect. The company processes 50% more logs, and sales have tripled since 2006.

Goby Walnut buys trees from Arborists, municipalities, parks and individual landowners within a couple hundred mile radius of their Portland location. They look for trees from two to over seven feet wide, and will pay from $500 to $20,000 for the right tree. These logs are milled into slabs, boards, and veneers that all fetch premium prices from high end furniture makers, musical instrument craftsmen, and woodworking hobbyists. Two of the rough sawn figured Oregon Black Walnut slabs on the company’s website are priced over $10,000, but Art also supplies boards and remnants for under $100.

With the increased sales and growing worldwide demand, Art saw the need to further expedite his milling and drying processes. He had been milling the huge hardwood slabs with chainsaw and swingblade mills, but knew that there had to be a more efficient way to accurately saw the premium logs and decrease the amount of precious wood being wasted in sawdust.

The WM1000 cuts down on sawing time, while improves yield

Familiar with Wood-Mizer’s thin-kerf  portable and industrial sawmills, he learned about Wood-Mizer’s most recently released machine, the WM1000 thin-kerfheadrig, which can saw a 67” log in half while only losing 1/8 of an inch in sawdust each pass. Art weighed the cost of the machine with its increased efficiency, cut quality, and unbeatable material recovery, and knew he had found exactly what he needed to maximize his profits from his logs.

With the WM1000 installed at his facility, and running full-time every day, Art is confident that the machine will pay for itself quickly. Every log cut yields an extra slab each time. Each large slab in his inventory ranges from $1,000 to $10,000 dollars each, which means a significant increase in profitability coming from the new mill.

"We recently cut a 15 foot, 48” diameter walnut log and were amazed to find that the thickness of the slabs didn’t vary by more than 1/32” over the whole 15 feet. Our finish on the slabs is much better than [our previous mill] and we yield an extra slab on every log. Another consideration is time…it takes about 10 minutes to complete a cut on a large slab…."  

Art Blumenkron

But the uses for this machine are not limited to just cutting premium slabs. “The WM1000 is great for any kind of sawmill business that deals with large logs, whether it be parting logs so they can be milled or sawing large slabs. It’s a lot of machine for the money!” Art explains.

Large slabs for furniture makers are not the only wood product offered by Goby. Gunstock blanks in three different varieties of walnut, cherry, maple and myrtle are available for muzzleloaders, rifles, and shotguns. Craftsman of musical instruments can find Oregon Walnut and Big Leaf Maple tonewood for most stringed instruments, providing superior sound and looks for the musical instrument.

For woodworkers, walnut veneers, book matched boards, turning blocks, remnant wood boards and blocks are available. Goby Walnut’s inventory also boasts large walnut, maple, redwood, and myrtle burls for tabletops.  

Art is continuing to research how to make his business more efficient and profitable. Right now he is sawing many smaller hardwood logs on the WM1000, which takes time away from sawing the big logs. He is looking at remedying that problem by putting in a Wood-Mizer industrial WM3500 to handle all his smaller hardwood logs and let the WM1000 concentrate on the big logs.  Art is also working with kiln manufacturers to see if he can utilize new kiln technologies to speed up the drying process while maintaining the integrity of the wood. Large hardwood slabs presently take 1-3 years to completely dry and be ready for resale. He would consider his investment worth it if he could process those same slabs within months instead of years.
