nowing the right thing to do isn't hard. Most. often, it's very obvious. Actually doing it is something else again. For example, we all know that we probably eat too much refined sugar and fat, but when the double chocolate cheesecake comes by, it's easy to convince ourselves that one piece won't hurt. By the same token, i.t doesn't take an MBA or a doctorate in economics 1.0 .. figure out that investing in the best new equipment we can afford on a consis- tent basis 10 keep our factories as up-to-date as possible is a wise business decision. Better to upgrade Lncrementally than one day 10wake up and discoverthe whole facto- ry is ten.jwerny or more years out of dale, and almost all the equipment needs replac- ing right away.
So why is it so hard 10 do that? A couple of recent conversationshave set me wondering about this question. Some employee of a high-production division of a very large company were effusive during a recent visit about how well their business is doing=-sales, production volume and profits are all setting records; business has never been better, Bu! they are not allowed to buy any new equipment now, even though a lot of the machinery needs upgrading, and invesnnent ill past years has been lagging, There might be a recession on the hori- zon, the corporate decision-makers explain. Better to keep thecash, But if the company's not going to buy new equipment when business is good, when is it going to buy it? During a recession? A tidy sum of readily available cash on the books may be a bit [ike that slice of choco- late cheesecake. It gives you a good feeling to have it right now, but is it really that good for you? Wouldn'l prudent investment in capital equipment be better overthe long haul? Another, :more ironic recent conversation was a variation on this theme. In this case, a manufacmrer told :me how he lost market share in recent years to competitors selling cheaper technology that wasn't as good as his .. ]t really hurt until customers started coming back after realizing that the 'cheaper" machines really weren't, when down- lime, repair and quality problems were factored into the equation. It had taken some of Ilis customers a while to relearn. the trui m that cheaper isn't neces. airily better. And yet this same manufacturer, who had suffered from the "cheaper is better" phi- losophy of others, didn't make the connection to his own buying practices. He was r still giving bottom-line price the deciding vote in purchasing decisions. Short-term ~I benefit looked better to him than long-term investment. I This herr-term strategy can burn you in the long run. In current conditions, only l- the companies thai have invested in new equipment and training and have adapted to I the changing environments in both their home and international markets will survive. I Punhermore, the effects ofthis kind of investment are geometric. These companies have more profits and cash now now to continue their investment, which only gives w .. them a greater advantage over the companies that lag behind. And thefarther behind the laggard companie that hoard their cash fall, the harder it will be for them to keep up. I'm not suggesting that price is not important or that now is the best time for every company to invest heavily in new equipment. II is possible to overinvest. or to invest unwisely or in the wrong equipment, But I think the greater danger now lies in under- investment in capital improvements that increase productivity and lower costs. That's a judgment call businesspeople have 10 make for themselves. But in making that call, beware of the temptation to go for the chocolate cheesecake every time, Short-term savings always look attractive at first glance. They may not be the best thing for the overall, Iong-term health of your company.

Dura-Bar" gray and ductile cast iron plays a dramatic role in the quality of the gears you produce. Dura-Bar's continuous casting process eliminates the scrap that results from the shrinkage. porosity, and tool-wearing inclu- sions that frequently occur in static-cast iron. , Moreover, Dura-Bar's consistent quality means you can confidently run it at speeds comparable to those with free-machining steel. Dura-Bar round bars are available in diam- ~ , 11 1 eters ranging from 5/8"' to ,20 and lengths of 6-20 ,. Bars also can be manufactured to your specific alloy 0 dimensional needs. Our extensive inventory means Dura-Bar IS available now - when you need it. And by 'eliminating the time and cost of pattern-making, you'll go from prototype to production immediately. Put it all together, and it means more quality gears for less cost. There's only one way to ensure that the gears you produce will always deliver superior performance. Make sure they're bred from quality stock.
