A silver salute to Wood & Wood Products' own Jerry Metz.For 25 years renown woodworking expert Jerry Metz has served up tens of thousands of dollars of free advice in helping Wood & Wood Products' readers solve their production and management problems. In celebration of Jerry's 25th anniversary as a contributing editor A contributing editor is a magazine job title that varies in responsibilities. Most often, a contributing editor is a freelancer who has proven ability and readership draw. to this publication, and in recognition of his enviable achievements as president of Metz Furniture Co., we proudly present a collection of features and photos culled from past issues of W&WP dating back as far as 1954. Included in the mix are reprints of two case histories on the J.L. Metz Furniture Co. published in 1957 and 1965. Under Jerry's stewardship, Metz Furniture of Hammond, IN, racked up an extraordinarily remarkable safety record in experiencing only one lost-time accident between 1948 and 1965. Jerry's relentless commitment to providing his employees with the safest workplace possible led Metz Furniture to win safety awards 10 years in a row from the National Association of Furniture Manufacturers (the only company to do so), as well as numerous local safety awards. Not surprisingly, when the NAFM NAFM Nippon Automatic Fine Machinery established a safety committee, it tapped Jerry to chair it. Jerry's close involvement with the association led NAFM directors to vote him "perpetuating treasurer" of the group, which has since merged into the American Furniture Manufacturers Assn. Jerry first hooked up with W&WP in the late 1960s as a member of the magazine's editorial advisory board. He sold off Metz Furniture and began a new career as a consultant, applying his four decades of woodworking experience to helping other manufacturers be more efficient. In January of 1971, Jerry began authoring "Consultant's Corner," a monthly feature in W&WP. The inaugural column, "Cost Reduction - the Name of the Game," was reprinted in W&WP's January 1996 issue. It set the tone for Jerry's often-repeated philosophy that successful companies adapt to the dictates of their customers and markets, keep their employees trained and motivated, continually update their machinery, constantly strive for higher quality and lower waste, and above all, maintain a safe work environment. Among his early assignments for W&WP, Jerry filed reports from the international woodworking shows in Hannover, Germany, and Louisville, KY. He was a strong proponent One who offers or proposes. A proponent is a person who comes forward with an a item or an idea. A proponent supports an issue or advocates a cause, such as a proponent of a will. PROPONENT, eccl. law. of using multi-functional equipment as a way to increase productivity and decrease labor costs. He also foresaw the importance that the panel processing equipment being developed in Europe would have on American wood products manufacturers. Consultant's Corner converted to "Consult Jerry Metz" and the popular question-and-answer format in August 1976; the first Q&A column is reprinted on page 54. Interestingly, Jerry's vision of the coming of the computer age in wood products manufacturing is reflected in his response to a reader's question published in December 1977, several years before the introduction of the personal computer. "Where the machines are complicated, the runs are large and the material cost is at stake, the computer is a must today. Obviously, not all operations are in that category. Rough mill, yes. Double end, yes. Moulders, yes. Yard operations, absolutely. I feel that all multiple operations in machining will be computerized. Completely computerized volume finishing lines will answer many needs and solve many problems. In general, computers are here for lumber, plywood plywood, manufactured board composed of an odd number of thin sheets of wood glued together under pressure with grains of the successive layers at right angles. Laminated wood differs from plywood in that the grains of its sheets are parallel. , furniture - the entire industry." While Jerry has expounded much on the potential benefits to be reaped by forward-thinking manufacturers who seize new technologies, he has tempered his support of capital investment with stern reminders to manufacturers that there are times when they might be better off buying components instead. Putting the make vs. buy debate aside, perhaps Jerry's greatest gift has been helping W&WP readers solve problems related to the fundamental properties of wood, especially those related to fluctuating moisture content. For 25 years he has preached that manufacturers must not lose sight of the fact that wood is a raw material unlike any other. It is prone to twisting, warping and splitting when subjected to changes in temperature and humidity. Successful manufacturers know how to properly store and ship their materials, components and finished products and know how to compensate for these anticipated changes during production, assembly and finishing processes. Judging from the phenomenal success of the woodworking industry's longest-running column, it is obvious that many learned at least some of their "know how" from Jerry Metz.

"JERRY" METZ From June 1951 and June 1976, Wood & Wood Products published a monthly feature titled "Wood Salutes." During its 25-year run, the column chronicled the achievements of some 300 people from the ranks of industry and academia. In March of 1965, W&WP saluted Jerry Metz for his furniture company's extraordinary safety record. It's not just by chance that J. L.

"Automation should contribute to safety," says the Hammond, Ind., firm's president, Jerry Metz, "but we also figure that we've got to be careful ... all in all we keep an eye on everything." Jerry Metz has well earned his reputation as a specialist in safe manufacturing methods. His plant has won the National Association of Furniture Manufacturers Safety Award for 10 consecutive years. In the sprawling greater Calumet Calumet, region, United States Calumet (kăl`y  mĕt'), industrialized region of NW Ind. and NE Ill., along the south shore of Lake Michigan. area, where the Metz firm has been pitted
against industries in all manufacturing categories, its safety records
have won frequent awards from the Calumet Industrial Safety Council. In
addition, National Safety Council files cite the outstanding job which
Jerry Metz has achieved in plant safety.
The manner in which he has put his beliefs into practice at his own plant has been described in magazine articles, among them articles appearing in Wood & Wood Products. The drive for top efficiency has carried over to his work for NAFM, for which he served as director for two terms before being named to the association's perpetuating office of treasurer in 1961.

I have been active in it for years and will now simply continue in work I consider highly important." Colleagues say that "active" is too modest a word to describe the work load he has shouldered on the association's behalf. One contribution was his help in setting up NAFM's safety contest committee for which he served as chairman from its inception. In 1930, following graduation from the University of Chicago, Jerry Metz joined the furniture firm founded by his father 32 years before. He subsequently worked in every phase of manufacturing and sales in the company, and still makes it a point to understand every process in the plant. He became president in 1951 and by 1954 launched a full-scale modernization modernization Transformation of a society from a rural and agrarian condition to a secular, urban, and industrial one. It is closely linked with industrialization. As societies modernize, the individual becomes increasingly important, gradually replacing the family, program (completed by 1959) to convert manufacturing of medium-grade furniture on a production basis to the economical production of high-style collections. He considers the modernization that took place then out of date and is presently hard at work directing another renovation which is expected to be completed by May. The plant has been described as one of the cleanest furniture factories in operation. Various beautiful furniture collections rolling out of the Metz plant have taken top honors for design as well as consumer preference in competitions sponsored by both the American Walnut Manufacturers Assn. and the Mahogany Assn. During World War II, Jerry Metz served as operations officer at the Ft. Bluff (AR) Arsenal where he designed and produced several vital ammunitions, receiving for his work the Legion of Merit Legion of Merit n. Abbr.

In competition with scores of less hazardous industries in Indiana's sprawling Calumet Industrial District, the Metz company has won first honors for safety for eight straight years. In fact, the firm has experienced only one lost-time accident in the past eight years! Here are the four general areas in which Metz strives to achieve as near perfection as possible in safety: (1) training employees, (2) orderly housekeeping, (3) new, safe machinery, and (4) adequate lighting. Accompanying photos show many specific ways in which safe conditions are achieved in the Metz plant. Many Metz safety innovations have gained wide acceptance in the wood industry, and the plant is frequently used as an "ideal standard" by various safety-rating bureaus. "There is no set formula for achieving safe conditions in the wood production plant," says Jerry Metz. "More often than not, you must be able to recognize an unsafe condition and then tailor a device or a safety practice to correct the situation. "We make no bones about the fact that a safe plant costs money, time and constant plugging - but it certainly pays off in both direct and indirect profit. Since 1954, our combined modernization and safety program has involved investments in more than 25 major new machines, re-painting of the plant's interior, a complete rewiring and lighting system, lumber yard lumber yard n (US) → almacén m de madera lumber yard n → entrepôt m de bois lumber yard n rearrangement re·ar·range tr.v. re·ar·ranged, re·ar·rang·ing, re·ar·rang·es To change the arrangement of. re and five new dry kilns dry kiln n.

The plant now produces more high-quality dining and bedroom furniture with a staff of 200 employees than it did several years ago with 383 employees. In scores of ways, both employees and machines are able to produce a better product. There have been no production slowdowns or stoppages caused by accidents. "A few furniture plants have up to 70 lost-time accidents each year," says Jerry, "while many average about 20. The National Safety Council estimates an average of two days lost in each lost-time accident. A plant with 20 accidents loses 40 days or about 320 man hours. Figured at $1.50 per hour, $480 in wages is lost and at least five times this dollar amount of production is detrimentally affected."

And, although exaggerated, the above example points out the fact that lost-time accidents can mean substantial dollar losses. Employee safety training Jerry, who serves as chairman of the NAFM safety committee, points out: "In hiring new employees, we prefer to pick out individuals who are 35 or older. Male employees in our plant now average about 55. We find that the older employees are more mature, steadier and much less inclined to commit impetuous im·pet·u·ous adj. 1.

They pay more attention to self-preservation practices." Metz company executives and foremen strive to keep the word "safety" always in employees' minds. A formal 30-minute safety meeting for all personnel is conducted on the first Tuesday First Tuesday is a networking forum for technology entrepreneurs, companies seeking venture capital, investors and related service providers. Founded in 1998, First Tuesday now has 38,000 members and the 10 branches across Europe host meetings on the first Tuesday every month. of each month. Outside speakers, such as fire chiefs or safety inspectors, give talks and demonstrations. Jerry Metz speaks at each meeting on a different phase of plant safety. A three-man safety committee, which meets regularly, is composed of Jerry Metz and two department foremen. One member of the committee, John Mathias, cabinet room foreman, also serves as full-time safety director. The director's word on safety in the plant is law. "To be at all successful," says Jerry, "you must have a safety director and the director's rulings must have teeth in them." The department foremen and the safety director check continuously to insure safe conditions in the plant. The committee conducts a formal safety inspection at unspecified times once each month. Jerry Metz makes two trips through the plant each day to check for safety and other production factors. As a special incentive for employees, a safety suggestion box is maintained in the office. Awards for suggestions on safety have run as high as a $50 bond and average $5 to $15. Orderly housekeeping "I've always believed that an orderly plant makes an orderly product and helps develop an orderly mind," Jerry observes. The Metz plant has been referred to as one of the most perfectly heated, humidified, dust-free and clean furniture factories in the nation. The plant employs a full-time janitor and several watchmen who are assigned specific cleaning duties. Foremen make regular cleanliness inspections each week - usually on Saturday morning when the plant is shut down. Various teams of employees working with their respective foreman also are assigned specific cleaning and maintenance tasks. Such jobs are performed at bonus rates at the end of the working day or on Saturdays.

Another agency checks for pest control pest control n → control m de plagas pest control n → lutte f contre les nuisibles pest control pest n once each month. Elevators and other equipment are inspected regularly by the manufacturers. New safe machinery More than 25 major new machines and a new kiln system have been installed at the Metz plant in the past three years. "Not only do you get better production and a better product at less cost per unit with new machinery," says Jerry, "but generally the newer the machine, the more safety features are included.

If we detect unsafe conditions, we install our own guards, covers, railings or whatever is needed to protect the operator and his co-workers." Adequate lighting Complete rewiring and installation of a new lighting system, begun two years ago, are now almost complete. The plant was built and originally wired in 1933.

Bulk storage is a feature. A fully-conveyorized finishing system, recently installed at J.L. Metz Furniture Co., Hammond, Ind., is paying off in four ways. 1. Capacity has been increased one-third to 110 pallets daily on one shift, with provision for up to 150 pallets per shift. 2.

More uniform control results from moving all finishing operations, except some painting, to one floor. 4. Use of airless spray has further reduced costs.

"We've spent about $100,000 on recent improvements (mainly conveyorization) in the finishing and shipping departments," says Metz. "The results have been satisfying, but I should point out that all hand operations, such as padding Bits or characters that fill up unused portions of a data structure, such as a field, packet or frame. Typically, padding is done at the end of the structure to fill it up with data, with the padding usually consisting of 1 bits, blank characters or null characters. See null and bit stuffing. , have been retained to maintain optimum quality. Practically all hand work is accomplished on the conveyor line." Maximum flexibility Key to the benefits enjoyed from the refurbished finishing department is the conveyor system. Several transfer points enable furniture parts to be shuttled to various operations, thus avoiding bottlenecks on the line. The 75-foot-long finishing conveyor is gravity operated, with the exception of those sections within the double oven and at transfer points where the line is pneumatically pneu·mat·ic also pneu·mat·i·cal adj. 1.

The best result is obtained by using flakeboard for the core and simple five-ply construction with special attention to equal pull of face and back. If you must use a wood core, the core strips must be reversed before gluing and must not be over 1 1/2 inches wide. Solids in this width are very difficult. Many use steel bands on the back, but even then, holding the boards perfectly straight in many climates is almost impossible to guarantee. My solution would be to make the boards of plied material, even if the tops must be solid. We use planed 12/4 oak and maple and glue two pieces together under adequate pressure to get the strength and thickness desired. Many of the 12/4 pieces spring open slightly after gluing, giving us a hairline hair·line n. The outline of the growth of hair on the head, especially across the front. that is rejected. We have checked every detail and can find no answer. What do you suggest? - Mr. G. Providing your planing is perfect and your moisture content is between 5 1/2 and 6 percent, the remedy is quite simple. Just before glue application and pressing, lightly dampen the surfaces to be glued with plain, room temperature water. Be sure your press temperature and dwell are OK and I do believe your troubles are over. We are making African mahogany African mahogany n. 1. a.

The best solution is the cheapest in the long run. Cut the extender to a minimum or eliminate it completely and use a super thin coat of virtually non-extended glue. This means the adhesive costs go up, but the rejects are nil and the extra cost is offset somewhat by setting the spreader spreader, n See condenser. to a minimum thickness that you will determine by experiment. We have been told we are adding expense to our sanding by roughing with 3-0 paper and then polishing with 5-0. We produce panels of walnut, oak, mahogany, cherry and maple and we have experimented with one good sanding using 4-0 without success. Also, we cut through too many edges with the 30 roughing. We need help. - Mr. B Mr. B may refer to:
You are among the many with this problem. Continue with the roughing and polishing on open-pore woods, but let up the pressure a bit as you hit the edges when using the stroke sander. Do not put any slightly bowed panels through a widebelt machine that is not designed to handle such irregularities. Your cherry and maple stock are to be sanded with 4-0 only, but in light, smooth strokes in the stroker and with minimum pressure in the widebelt. This requires an extra pass, but is definitely saving for these two species. We lose too much stock from the top of our lumber piles due to weathering. We have tried a lot of remedies. Should we go to the expense of building an open shed to keep the air drying process out of the sun and rain? - Mr. K. I do not like open sheds unless the area has a great deal of air movement. Even then, uneven air drying and some "souring" is apt to take place. Placing old lumber or plywood on top of stacks is costly and not nearly as good as an investment in weatherproof tarps specially prepared for this purpose. They are made with rope grommets to enable you to tie them and are not lapped over the standard size bunks by more than a couple of inches to allow good circulation. Experience tells us that the top layers of the bunks do receive ample air and are consistent with the balances of the load. |
