(l-](g Presidents, kings, world statesn rnilitarv men and women, corporte |lrads. and millions of others all r the world, own Zippo lighters. The eompanv produces 33 models of p.htcrs. ranging from S4.75 in brushed (|irome to S560 in 14K gold. Its basic line consists of two standard sizes: a -hm model, that is about 114-in. wide jn(J 2]4-in. Iiigh: and a standard model that is approximately lAo-in. wide and oi4-in. high. According to Ray Lhler. Zippo's plant manager, tin lead solder plays one of the most critical roles in the efficient manufacture and operation of the fault ier lighters. He says this is why the ..offering operation includes verv string ent qualitv control procedures. Lhler explains that solder preforms hterallv help put the "zip" in Zippo lighters. The preform is used to solderjoin and seal a plate to the inner ease L the lighter. W hen this case is inserted min the outer shell of the lighter, the rr-uiiina en\elope forms a sealed enclo sure that contains the wick and the ab sorbent packing to hold the fluid used to fuel the lighter. Therefore, the sol dered plate must form an airtight and Irak-proof seal with the inner case. Otherwise rapid evaporation would waste tin- fuel and require too frequent re idling.
All solder preforms used in the join ing process are 50/50 tin lead alloy. The preforms varv in length and width, depending on whether slim- or regular ize lighters are in production. Regular he preforms are ,015-in. thick, while the thin-size preform is .017-in. thick. The thickness variation is due to the difference in gauge of the stainless steel used for the two cases--.015-in. for the slim case and 0.018-in. for the regular rase.
About -10 Of of Zippo's sales volume
comes from more than 2 < ,000 commer cial accounts, comprising some of the biggest corporate names in industrv. Thev regularly order Zippos in huge lots to serve as premiums, promotional handouts, emplovee awards and sales in centives. Main times the company em blem is soldered on the face of the lighter. "If vou solder an emblem on. vou know it's going to stay. " says plant Manager Lhler. "If the emblems are epoxy-joined to the face of the lighter, vou know that sooner or later, they will come off. We've tried other joining tech niques. too. but we alwavs come back to solder because it's the best and most economical joining method we've found.
He also points with pride to the fact that few of the thousands of lighters the Zippo repair section processes each day irnolve resoldering. Some bear the ravages of having been soaked in sea
water, buried in snow or embedded in mud. Others have been mangled by washing machines, hydraulic presses and lawn mowers--and a few stopped
bullets in World War II, Korea and
Vietnam. Regardless of the reason for return, the lighters are enroute to their owners within 48 hours--included is a one-shot tube of Zippo lighter fluid and a couple of extra Zippo flints to boot.

Sound enclosure softens punch of press noise
Industry face? heavy pressure today to comply with the noise control regu lations of the Occupational Safety & Health Act I OSH A i. When it comes to generating excessive industrial plant noise, automatic punch presses are among the leading offenders. So when a company like Associated Spring real izes a 17 db reduction in such machine ry noise, it can lie credited with quite an accomplishment. It can roughly be compared to paring down the painfully loud noise of a riveting gun to the sounds of city traffic heard from within an automobile.
The company's Dayton. Ohio plant uses a number of huge presses to pro duce various type springs and custom metal parts. In an effort to meet OSHA's current 90 db industrial noise limit re quirement. locallv-hased acoustic engi neering consultants were brought in to

Before the sound enclosure installa tion. the noise level reading was 101.5 db. despite the installation of vibration isolators to decouple the press from the floor. This compares with a post-enclo sure reading of 84.5 dh. The 17 db at tenuation achieved, without sacrifice in production capacity, convinced the com pany to install a similar enclosure for the second offending 15-ton press.
Tom Campbell, division manager, noted that the noise reduction exceeds present OSHA requirements. And should a currently contemplated lower standard of 85 db he put into effect, the company would still he within compliance limits. "We were especially pleased to note im mediate workers' acceptance of this new system as an improvement to their en vironment and safety." Campbell said.

jiower. although the use of lead in golf irons n0[ new. the traditional wav to add
-oncentrated weight for golf irons was to load the inside of the shaft with chunks of lead near the point w here the head is attached to the shaft. This tech nique adds deadweight that has been re ported to cause problems in achieving a smooth swing.
Shamrock Golf Co.. Los Angeles, has taken an approach that it hopes will overcome the deadweight problem. Their solution is to move the lead weight from the base of the shaft to a special spot inside the clubhead. The concept is re ported to not onlv work, but to improve the performance of the iron as well.
According to Shamrock, their method makes the overall weight of the iron less. Jack Nicklaus in a recent article in Golf Digest is quoted as saving: `'Dis tance is a problem for both seniors and women, and I think there are two rea sons. The first lies in equipment, i've increasinglv favored 'light-swinging' clubs as I've got older, and I think I'll jo more and more in that direction in the future. One reason is that clubhead velocity has twice the value of mass in terms of distance--the lighter the club, the easier it is to swing through the ball fast. Also, the lighter the club, the less it takes out of you physically to swing it. This can be a big factor as one tires towards the end of the round."
Called a Power Pocket, the lead weight lowers the center of gravity and places the heaviest part of the clubhead below the center of the ball. Shamrock says its long irons using the lead weight
give the high, arching flight of a five wood, while short irons using it give more bite.
shamrock reports the improved tech nique is more time consuming and ex pensive. but it results in a higher quality product with improved precision. The first step in producing the head is to cast the basic head of the golf club. The faceplate is then stamped from the same type of metal and it is joined to the clubhead bv electron beam fusion, a process that fuses the two metals to gether to become one homogeneous piece of solid steel.
In the next step, the desired lead weight is dropped into the bottom of the cavity directly in back of the face plate. The weight of the lead depends on the type of club being produced and the swing weight desired by the golfer. Swing weight is the relationship of the weight of the head to the length of the club. Shaped somewhat like a piece of chewing gum and ranging in weight from 2 grams to 23 grams, the lead weight is held in place with black epoxv.

Reloading: A quick, simple and economical way to get more shots for the money
Thousand? of people involved in sports such as skeet and trap shooting are finding that "packing their own'' can save a great deal of money ... in this case, money that would be spent for new ammunition. ^ ith special equip ment that's readilv available, it's a com paratively simple task to reload shells with complete safety and reliability pro viding that recognized reloading pre cautions are taken.
It is particularly important to follow the instructions contained in arty one of the various reloading manuals available at any hunting or sporting goods store. Particular care should be taken to start with the lowest recommended charges listed for each load in such manuals.
There are literally dozens of shotshell reloading tools on the market. They range in price from a S9.95 pocket-tvpe outfit that reloads a box of shells in an hour to semi-automatic equipment that can produce nearly 500 shells per hour. The a\erage shooter's needs can be ade quately met by tools in the S45 to $85 price range. All of them are self-con tained units that can load three or four boxes i 75 to 100 shell? I per hour.
The first step in reloading of a shot gun shell is to select a clean, fired case in good condition. The cases must be stored by make--Remington. ^ inchester. Federal, etc.--and type--12. 16 and 20 gauge, because of reloading require ments.
Both plastic and paper shells are abundant, but care must be taken to adjust tools to handle them. For ex ample. target loads contain light charges of shot and powder and are loaded in "high-base, permanent-wad" cases. Hunt ing loads, on the other hand, use heavy charges and are assembled in "lowbase. permanent-wad" cases of greater internal capacity.
Before loading, check to make sure that all cases are carefully inspected. Cases that have been mashed flat, seri ously deformed, or torn, should be set aside.
Basic components needed for reload ing begin with standard domestic "bat tery cup" shotshell primers that are available in several makes. All makes
are good and all currently produced 12 gauge shells take No. 209 size. The best wads are the one-piece plastic wad column shot-cup type. Different cases have different height wads and all deal ers have charts telling which is correct for a particular case. The lead shot is the same no matter who makes it. Size No. 9 is usually chosen for target loads.
Safety precautions are of critical im portance in reloading. Some of the pre cautions are ob\ ious--one should al ways wear safety glasses, never load in haste, and never smoke in the area. Primers should be carefully handled since they are the most hazardous of all components used for smokeless pow der loads.
It is also vitally important to keep powder and primers away from heat, sparks and open flames. Powders should never be mixed and all shells must be carefully examined to insure they are in good condition before using.
Though it must be accomplished with utmost care, reloading is simple. In the first step of a typical operation, the shotshell case is placed in a tube. At the bottom is a de-capping punch which pushes out the old primer. A downward movement of the tube seats the new primer. After it is seated, a carefullyselected amount of powder is passed into the case via a hollow tube. A wad is then inserted in the case atop the powder and lead shot is next passed into the case and seated in a similar manner. A pressure gauge at the base of the de vice shows the exact wad pressure. A cap-like die device with grooves inside is then placed over the case and, when

ncreasing energy costs are a major
I factor in the design of new buildmas. or the renovation and moderniza tion of existing structures. ^ ithout economical enersv to provide electricity and heatins. buildings become uneco nomical to own and operate unless the added expense for energy is absorbed in higher priees for manufactured products, and increased rentals for office space and housing.
One solution for supplementary elec tric energy needs is solar power from on-site sources. Incorporated into the total design or redesign of buildings, it is being stored in lead batteries from two solar sources--sun and wind. Such energy sources, when combined with these batteries, can provide much of the electrical energy required for tomorrow's buildings. A look at developments under lay today shows how this might be ac complished.
An excellent example of how such solar power sources can be combined ls a project now underway at the Research and Development Institute 'REDE i in Providence. R.l. REDE is
the prime mover in establishing the Rhode Island Energy Conservation Sta tion ( RIECS i. which is to be housed in a recycled brass factory building originally built in the 1840 s. RF.DE is assembling a w ind and sun solar energy package that will provide for most of the building's heating, hot water and electrical needs. In addition, a miniature hydro-electric power plant to be installed in a small river that runs alongside the building will provide some electrical energy for the renovated structure.
REDE's basic concept is to generate electricity from the wind and sun sources and store it in a large bank of lead acid batteries. The batteries are a key element to the REDE concept. REDE will utilize solar cell semi-con ductor devices which convert light di rectly into electricity. The best known of these devices is the silicon solar cell. Solar cells themselves have no storage capability. They generate only while ex posed to light. Since the power is usu ally required continuously, lead storage batteries will be used to store power
that can he used during the time the solar array is in darkness. During the daylight, the array charges the batteries and handles the electrical load require ments, A multiple battery storage fa cility will be installed in the basement level of the RIECS building to store electrical energy. The lead batteries will be installed in such a manner that they can be vented through a basement level window on the river side of the build ing. Present plans call for installing ap proximately 50 batteries to collect en ergy from all three electric generation sources scheduled for installation. Ad ditional batteries can be installed as needed. It is significant to note that the combined solar cells and wind genera tors will help to insure that the batter ies are constantly being charged.
Two wind generating devices will also be installed in the RIECS building. One is a Darrieus wind plant that looks much like a giant egg beater, while the other is an improved version of the ^ estern-type w indmill that is commonly found on farms

Buckles are produced by a process called spincasting. It provides for fast, economical casting of most castable metals and plastics. Developed by Bomanoff International.

Whether constructed from ready-made

joining certain parts with an adhesive,

t.xerting pressure on the parts until the

ponents that are too big to accommo

airfare of the parts involved is another
mnsideration.
A resourceful upstate \ew Torker
faced this problem when constructing a
,-offee table of his own design. He re-

clamps. Simply stated, he "took the lead
mit" of skeet shouting to hold the table
components in position until the bond

The table was designed with an oak
inlav top. over a plywood base, with tun sets of -1-in. thick oak legs. The Aft. x 2-ft. top was covered with 400

oak tiles, approximately :!4-in. x :>-in.. all carefully organized and glued in an intricate pattern. As a result, there was no suitable clamping surface to bold the legs against the underside of the table during the gluing process. The use of wood or metal type clamps would mar the highly polished surface of the tiles and oak legs.
It was at this point that the furniture maker derided to try lead 'hot. a pro duct of his skeet shooting liobhv. These pellets, packaged in cloth bags of 25-lbs. each, are used to reload shotshells. Here was an excellent source of concentrated weight in a soft flexible form that would not damage the wood surfaces. With two 25-lb. bags of lead shut positioned on each of the table legs, the duinu job was accomplished without rni-hap.
The lead shot has since been used for fdling 12-gauge shells for the skeet shout ing and hunting season. However, addi tional bags are always on band to piovide lead shot "i-lampina" for future gluing jobs.
Handmade furniture designers who are not hunting enthusia't- will find liags of lead shut readily available at most sporting good' stores. A one-time investment in lead shot can Milve many "sticky gluing problems similar to those encountered by the \ew York hunter furniture builder.
