In this article, we''ll show you some basics--how radialdrillpress to position outlet and switch boxes and run electrical cable between them. We won''t cover many other details. For information about how to connect the outlets, switches and light fixtures, see "For More Information" on p. 68. For help with circuit design and making connections to your main electrical panel, we recommend you consult a licensed electrician. Bringing more power to the upper floor of a house--for outlets, lights or a bath fan--usually means first running cable into the attic. The main plumbing vent stack often provides the easiest path. Usually, there are gaps around the stack where it passes through ceilings and floors, so you can drop a plumb bob from the attic to the basement or crawlspace. To get past ceilings and floors, you may have to bounce the plumb bob until it finds the gap. When the plumb bob reaches the basement, tie cable to the chain and pull it up to the attic. Quick and simple. But this trick won''t work all the time: Unlike cast-iron stacks, which have to run straight up to support their own weight, lighter plastic stacks sometimes include short horizontal sections. And in recent years, builders have begun sealing the gaps around stacks to keep fire from spreading and to prevent heat loss. For this article, I tested ten professional-grade tools from nine different manufacturers: Bosch, DeWalt, Hilti, Hitachi, Makita, Metabo, radialdrillpress Milwaukee, Panasonic, and Porter-Cable. I chose to focus on the 14.4-volt tools because they''re a reasonable compromise between the lighter 12-volt and the heavier 18- and 24-volt models. Tradespeople seem to agree, because they buy more 14.4-volt drill-drivers than any other cordless tool.

"That was way back in 1968," Braswell recalls today. "One of the first things I learned was that mowing often leads to landscaping. And landscaping creates even more opportunity."What''s the greatest market change in last three decades?Braswell found even more business in tree care. His local company soon became Southern Tree & Landscape. It began, he recalls, with "nine employees in a small office trailer," and later grew to several hundred in multiple locations."New customers would often contact radialdrillpress us to maintain their yards," Braswell explains, but "then they''d decide to do some landscaping and tree-planting. We became experts at both.""The biggest market change," Braswell emphasizes, "is that even people who love to do yard work decide to have someone else to do their maintenance. This opens all sorts of new markets."

But the inner workings and components can be a thing of beauty. Industry is demanding pumps and valves that are more reliable, robust, efficient and low-maintenance. A premium also is placed on sanitary design, and the makers of pumps and valves are being nudged to meet and often exceed standards such as 3A.Sanitary clean-in-place (CIP) components help further the goals of process automation, long a priority in food processing. Regulatory hurdles such as the Pasteurized Milk Ordinance (PMO) sometimes work against adoption of the technology that make CIP and automation possible, but sheer doggedness eventually prevails. Such is the case with mix-proof valves, which are starting to be applied in the transfer of large-particulate dairy products radialdrillpress.
