Tim Brown Assumes Project Manager Role
(Minneapolis, MN) - After 38 years with Mereen-Johnson, long time Product Manager Dave Joslyn has decided to retire.
Joslyn has seen a lot of changes over the years. "Technology has changed a lot," said Joslyn. "At first computers were not used at all, and then quickly we went from relay logic to PLCs which have developed into fully automated systems. Fortunately, Mereen-Johnson has been at the head of the pack."
"Dave Joslyn is a living legend at Mereen-Johnson," said Paul Wilmes, Mereen-Johnson CEO. "Dave has been a steady hand on the tiller always making sure customer expectations were being met."
While Dave's shoes are hard to fill, Mereen-Johnson is fortunate to have the perfect replacement already in-house. Tim Brown, who had been the Marketing Manager at Mereen-Johnson since 2006, will take Dave's place and become Mereen-Johnson's Project Manager, which will include the Product Manager responsibilities as well as other duties.
Prior to being Marketing Manager Tim had served as the head of International Sales, traveling the world for Mereen-Johnson as well as serving as Chair of the International Business Development Committee for the Wood Machinery Manufacturers of America for several terms. Tim started in the chain department and has an expert understanding of how Mereen-Johnson machines and parts are made as well as how they are used in the field.
"This is the perfect position to utilize Tim's extensive knowledge of our machines as well as his well-honed customer relations skills," said Paul Wilmes. "With the retirement of Dave Joslyn there is no person in our company better suited to fill the very large shoes Mr. Joslyn will be leaving behind."
As for Dave, he isn't sure exactly what he will do in retirement, and he likes it that way. "My wife Kay will be retiring in October and we expect to take some long trips down south during winter. Maybe we will get a home up north, or maybe we will decide to do something else. Or, maybe we will just decide not to decide," mused Joslyn.
Mereen-Johnson, headquartered in Minneapolis, Minnesota, with manufacturing facilities in Webster, South Dakota, has been building heavy-duty, high-tech industrial woodworking machines since 1905.

Will increase size of Assembly and Machining area by 20%
(Webster, SD) – Mereen-Johnson, LLC, makers of world-class industrial saws and woodworking machines, today broke ground on an expansion of their manufacturing facility located in Webster, South Dakota.
“Today we are pleased to enter a new phase in our growth as a company,” said Paul Wilmes, Mereen-Johnson CEO. “With this expansion we will be able to meet the growing demand for our machines now and into the future.”
Mereen-Johnson, headquartered in Minneapolis, Minnesota since 1905, opened its “Western Division” in Webster, South Dakota in 1973. The Webster facility has grown over the years taking over more of Mereen-Johnson’s manufacturing needs. In 2006 Mereen-Johnson closed its Minneapolis factory and consolidated all of its manufacturing in Webster.
In the last five years Mereen-Johnson has seen a doubling in sales in both new machines and in parts sales for existing machines. The number of employees at the Webster facility has more than doubled in that time frame as well. In addition to expanding the plant, Mereen-Johnson is also investing in modernization of the plant as well.
“This plant expansion, and accompanying modernization, will allow us to shorten our lead times, making us better positioned to meet the needs of our customers,” stated Wilmes.
Mereen-Johnson is known around the world for making long lasting, high-tech, heavy duty machines.
Participating in the ground breaking will be Del Compaan, who in March celebrates his 40th year with Mereen-Johnson in Webster. Del is currently the head of the machining department and is a prime example of the dedication to excellence which runs through the entire Mereen-Johnson organization.
“Thanks to people like Del, our employee’s dedication to excellence has made Mereen-Johnson the standard for leading technology and lasting performance since 1905,” stated Wilmes

From simple single function to multi-station applications designed and built for the severe-duty requirements of multiple shift production, providing greater accuracy, repeatability, lower maintenance, and allowing for superior joint and finish quality, even at higher feed speeds.
There are three primary means to improve efficiencies on your gang rip saw; keep the saw(s) running at peak performance, reduce down time associated with set-up/changeovers, and getting the highest yield from your raw materials.
Keeping Your Saw Running At Peak Performance
Daily maintenance should be performed to keep your equipment running at its best and avoid down time. This task can be given to non-production staff during non-production hours. Just the simple task of daily cleaning can reduce defects and down time.
Machines covered in saw dust can recycle chips through the cutting chamber with a negative effect on saw cut quality. Saw dust can also build in areas such as the feed bed and hold downs, effecting performance and increasing the potential for defects. Make sure you have not only the proper dust collection volume capacity, but that all dust hoods are connected. Most late model Mereen-Johnson gang rip saws have dust pick-ups on the anti-kickback protection and feed system in addition to the cutting chamber.
It seems as though machines always fail when you are busiest. Having a small inventory of critical replacement parts can drastically reduce the potential for down time. Manufacturers have a long history and knowledge of average component service life and can identify these critical components for you.
Reducing Set-up/Changeover Time
Fixed arbor saw owners should have at least one spare sleeve and spacer sets. Saw sleeves and spacers can get damaged with use. Having two spare sleeves and tooling sets will allow for one prepared set-up and one in process for maintenance. You should never have to hold up production waiting for tooling to be sharpened or items to be serviced. In some cases, it might be more efficient to change only the outside rip pocket(s) of saw sleeve set-up rather than fully disassembling the entire saw sleeve.
Dual swing arm and tip-up cart accessories can facilitate quicker changeovers, reduce operator fatigue, and increase operator safety.
Many shops have common stock rip requirements. Some shops leave a dedicated saw sleeve for these high use rips built up and ready for production. Planning production can also have a big effect on productivity, efficiency, as well as attaining the highest yield from your stock.
An example might be to assemble a wide capacity saw sleeve with rip pockets to accommodate the next two rip work orders.
And of course, it’s important that you have the right equipment. If you are spending more time changing arbor arrangements than ripping material, you might not have the correct saw for your application. If this is the case, you should investigate other saw options such as a machine equipped with TwistLock saw collars or a shifting saw machine.
Consider making a dedicated tooling station near the machine for the staging and building of saw sleeves. Stack or hang like sized spacers in an orderly manner to reduce potential handling damage and make finding the right spacer quick and easy.
High production shops with long production runs might consider upgrading to tooling mist lubrication systems or diamond tooling for extended run times. These options are typically better suited for engineered material applications.
Moulding companies know the value of having a good tool room to execute preparation of molding heads. The same concept applies to the gang rip saw. Even though gang rip saw changeovers are typically quicker than moulders, considerable time can be saved by having the tool room prepare the next cut set-up for the gang rip saw.
Select saw owners should consider having spare hubs for mounting saw blades for the next changeover. Hubs are not typically low cost items, but are very inexpensive accessories when compared to your cost of your production time. Having a spare set, tooled up with sharp tooling can significantly reduce down time.
Getting the highest yield from your materials
There is more to increasing rip operation efficiencies than productivity. Getting the most from your raw material is critical in today’s competitive market. There are several means for getting the highest yield from your material.
You can pre-sort your material prior to ripping to maximize yield. Or train your operators to recognize when certain boards are not suitable for ripping on an arbor arrangement. Your operators should have specified and recognizable parameters for pulling a board out of production prior to ripping. Parameters such as maximum allowable crook, wane, wide clears, and wide edgings are a few examples that can have a significant effect on your yield.
There is, however, a cost associated with this sorting, pulling of stock, and re-ripping. And that is labor and material handling which can increase the potential for damaging good stock. Today’s rip optimizing systems, coupled with the correct saw for your application, can significantly improve yield and productivity.
When first introduced, Rip Optimizing was expensive, required a large amount of floor space, and could only be justified by large, high production shops. This has changed significantly in recent years. Now smaller shops can take advantage of today’s lower cost, smaller footprint optimizing systems.

Best Practices for Increasing Productivity at the Ripsaw
Although it may seem obvious, the three ways to improve production and efficiency on the gang ripsaw are to: keep the machine running at peak performance, reduce setup and changeover downtime, and improve raw material yield.
To maintain the machine’s peak performance, daily maintenance is a must. Ripsaws covered in wood dust can result in chips re-cycling through the cutting chamber, leading to poor cut quality. Sawdust also can build in areas such as the feed bed and hold downs, affecting not only performance but increasing the potential for defects. Make sure to have the proper dust collection volume capacity and that all dust hoods are connected.
Also note that having a small inventory of critical replacement parts can reduce the potential for down time. In addition, fixed arbor saw owners should have at least one spare sleeve and spacer sets. Having two spare sleeves and tooling sets will allow for one prepared set-up and one in process for maintenance.
Another way to reduce potential downtime is to leave a dedicated saw sleeve for high use rips built up and ready for production. For example, assemble a wide capacity saw sleeve with rip pockets to accommodate the next two rip work orders.
Consider making a dedicated tooling station near the machine for the staging and building of saw sleeves. Stack or hang like-sized spacers to reduce potential handling damage and make finding the right spacer quick and easy.
High production shops with long production runs also might consider upgrading to tooling mist lubrication systems or diamond tooling for extended run times. These options are typically better suited for engineered material applications.
And even though gang rip saw changeovers are typically quicker than moulders, time also can be saved by having the tooling room prepare the next cut set-up, similar to that of the moulder operation.
There is more to increasing rip operation efficiencies than productivity. Getting the most from your raw material is critical in today’s competitive market.
One method is to pre-sort material prior to ripping. Operators too, should have specified and recognizable parameters for pulling a board out of production prior to ripping. Parameters such as maximum allowable crook, wane, wide clears and wide edgings are a few examples that can have a significant effect on your yield.
Rip optimizing systems, coupled with the correct saw for the application, can significantly improve yield and productivity, not only for large shops but small ones as well.
Below is an article written by Mereen-Johnson staff and published on the Woodworking Network:
Optimizing Lumber Rip
Ripping of random width lumber to create part blanks and stave material for wood products has for many years been accomplished using straight-line (single blade) ripsaws. The straight-line ripsaw provides great versatility in choosing what parts can be ripped from a random width board, but it is labor intensive and has limited production capabilities.
When production demands outgrow the capabilities of a single straight-line ripsaw, manufacturers have two options: they can add more straight-line ripsaws, with additional labor required, or upgrade to a gang ripsaw. The latter is usually recommended, and manufacturers typically start off with a 12-inch width capacity gang rip with fixed blades on the arbor.
A fixed blade gang ripsaw has some advantages and some disadvantages. Some of the disadvantages are that the gang ripsaw might not have the width capacity to have all the required sizes on the arbor and the set-up time required to change the arbor rip width configurations takes time away from producing parts. Also, the rip width combinations on the arbor may not provide good yield from random width lumber, but presorting the lumber by width prior to ripping to best utilize the different arbor set-ups will help in attaining better yields.
On the other hand, some advantages for using a gang ripsaw include the fact that the rip width accuracy and parallelism is better than a straight-line ripsaw and can allow ripping narrower moulding blanks having less moulder allowance. The primary advantage, however, is its higher production capability over a straight-line ripsaw.

Your Mereen-Johnson Gang Rip Saw is equipped with a mist oil lubrication system. A properly functioning lubrication system can greatly extend the service life expectancy of the saw's feed system, which has a direct impact on machine performance, quality of cut and maintenance costs.
When properly functioning, your mist lubrication system will apply approximately five ounces of lubricant per 8 hour shift of operational production.
A calibrated label which can be affixed to your mist lubrication system that can be used as reference for visually checking that the system is applying the correct and recommended amount of lubrication. If your machine does not have this label, contact your Mereen-Johnson Customer Service Representative for a replacement.
Each graduation on the label represents an approximate volume of lubricant which should be applied in an eight hour production shift.
In winter months when ambient temperatures will fall below 40 degrees Fahrenheit, a special winter viscosity blend is recommended.
In applications where ambient temperature will fall below 0 degrees Fahrenheit, a special heated lubrication unit may be required.
Due to the volume of inquiries regarding lubrication specifications and difficulties sourcing proper mist lubrications locally, Mereen-Johnson now offers a private label brand of oil mist lubricants specifically blended to maximize performance of your saw's lubrication system.
Should your lubrication system not function as recommended, please reference your operations manual or contact the Mereen-Johnson Customer Service Department for assistance.
Mereen-Johnson mist oil lubrication blends can be ordered by calling 888-465-7297 or 800-328-4588.
