• Power Tools History

    Since the ancient Egyptians began using a hand-powered lathe centuries ago, man has striven to make arduous building and assembling tasks easier, quicker, and more efficient through power tools. We’ve come a long way from those sand-covered turning machines, but the end goal is no different from our desert-dwelling ancestors. Today, nearly every home in every industrialized country houses and uses power tools.

    Even though the concept of the power tool has been around for a long time, it wasn’t until the late 1800’s when the first modern-era power tools became possible. The advent of electric motors made highly-efficient stationary and portable power tool technology a reality, and high-speed assembly lines made power tools both affordable and profitable.

    The Bosch company was at the forefront of power tool technology in those early years. Founded in 1886 Germany by Robert Bosch, the company initially focused on automobile components with integrated electric parts, and was responsible for such developments as the first low-voltage magneto ignition. Before long, companies in other industrialized nations began developing the first electric power tools, and Bosch introduced its first power drill in 1932. Today, Bosch still engineers and manufactures automotive parts, and its power tool division has grown to include nearly every household and assembly tool on the market – including power drills, belt sanders, circular saws, and more. As part of the company’s growth, it has acquired other successful power tool manufacturers that started during the same early 20th century era.

    In 1923, American inventor Raymond DeWalt introduced the world’s first radial arm saw, a sliding circular saw that could make long cuts with accuracy. One year later, he founded the DeWalt power tool company in Baltimore, Maryland; another company that has grown substantially over the last 85 years. At the forefront of portable power tool technology, DeWalt’s power tools are revered by carpenters and homeowners alike for their long-life, durable cordless battery-styled power drill, circular saws, and other power tools; and the company currently manufactures over 200 types of power tools worldwide.

    Founded in 1915 in Japan, the Makita Corporation has also staked its reputation on cordless, battery-powered power tools – most notably, the hand-held drill, which Makita introduced in 1978. Nine years later, the company had a full arsenal of cordless, professional-grade power tools for contractors. Today, Makita manufactures over 350 different power tools, both portable and stationary, and the pronounced teal color emblazoned on all of their tools is often mimicked by others trying to capitalize on Makita’s reliable name.

    The early 20th century proved to be a hotbed of power tool advancements, and many companies worked hard to develop profit-turning innovations that moved their products off store shelves and into people’s homes. While the term power tool traditionally conjures thoughts of electric drills and sanders, machines like the pipe threader and utility pump are also considered power tools. This is the area the Ridgid company focused on when it was founded in Elyria, Ohio, in 1923. Still a leader in the plumbing tool industry, Ridgid now has a power tool division that focuses exclusively on contemporary power tools and has released its own saws, drills, and even air tools.

    A.F. Siebert founded the Milwaukee Electric Tool Company one year later in Milwaukee, Wisconsin. Known for manufacturing heavy-duty power tools, Milwaukee is best know for the ‘Sawzall,’ one of the most widely-used reciprocating saws in the world. Like their power tool manufacturing competition, Milwaukee currently produces portable and stationary power tools like circular saws, drills, band saws, grinders and sanders – over 500 different models in all. Unlike their competition, many of Milwaukee’s power tools are released in both 120 and 230 volt models, drawing the line between household and commercial/industrial power.

    Best known for the Skilsaw they invented in 1924, the Skil power tool company evolved out of the Michel Electric Handsaw Company when they entered the power tool market. Fueled by the ingenious circular saw invention, the company elevated itself to the upper echelon of the small power tool industry with jig saws, grinders, sanders, and a whole slew of handheld, cordless power tools. In 1996, the Bosch company purchased Skil but still keeps its power tools on shelves worldwide as one of the most popular power tool lines on Earth.

    The Delta company has changed hands several times since it was founded by Herbert Tautz in 1919 in his Milwaukee, Wisconsin garage. Tautz focused on small tools but when Delta was purchased by Rockwell in 1945, the company made a profitable shift to the stationary tools – like planers and bench sanders – it’s renowned for today. Delta isn’t the only name this line has carried, however; Rockwell enveloped the company on takeover before selling it to Pentair, which re-introduced the Delta name before selling out to Black & Decker …

  • 10 Ways to Improve Your New Ghillie Suit

    1. Replace all buttons with Velcro.

      If your buttons are constantly getting caught on things while you are crawling then you should consider replacing all of your buttons with Velcro. Now you won’t be getting caught up while crawling.

    2. Add both elbow and knee padding to your new Ghillie Suit.

      If after a long day in your Ghillie Suit you find that your elbows and knees are sore then perhaps you should add padding. One trick I read about online was to sew in mouse pads as they are very flexible and provide enough padding to save your elbows and knees.

    3. Add a Camelback to the suit.

      How many times have you gotten thirsty when you couldn’t afford to reach for your canteen? Even if you haven’t then you would still benefit from incorporating a Camelback into your Ghillie Suit. After adding one then you won’t even have to move to quench your thirst without giving up your position.

    4. Get Dirty.

      As strange as it may seem at first, you should get that new suit dirty. Have you ever seen a dirt free outdoors? Me either, so crawl around and get it dirty!

    5. Replace the armpits with mosquito netting.

      One thing about these suits is they tend to be heavy. If you are out in the humid and hot woods you could easily overheat before even realizing it. Now imagine how much cooler you would stay if you replaced the armpits with netting? What about replacing a small portion of your back and chest with netting? Before long you will have taken the temperature in that suit way down!

    6. Add your own vegetation.

      The goal of your new Ghillie Suit is to blend in to your surroundings. There is no better way to blend in then to actually wear your surroundings! Don’t be afraid to add some leaves so that you blend in just that much better.

    7. Do not wash your Ghillie Suit.

      There are a few reasons not to wash your Ghillie Suit. One of which is for a safety. When the suit is washed it removes the fire retardant. You then have to reapply the retardant in order to return to the previous safety level. More so, you would be washing away all the foliage, etc that you have managed to pick up on the suit as you have worn it!

    8. Add thumb loops to your sleeves.

      Do your arms start moving up as you are crawling? One way to fix that is to sew on thumb loops to the end of your sleeves. This allows you to put your thumbs in to them and will prevent your arms from riding up while you are trying to get into a better position for that perfect shot.

    9. Add leg cuffs to your pants.

      Another common problem is that the pant legs will start riding up while crawling in prone. With the addition of some leg cuffs you can easily keep those pant legs in place so that the only thing left for you to worry about is that perfect shot.

    10. Add more pockets.

      I just can’t seem to have enough pockets. Don’t be afraid to add a few more of your own. Just make sure they are well hidden and are easy to reach!

  • Top 5 Advantages of Cast Aluminum Furniture

    If you have been on the lookout for furniture for your living space, you’d be the first to agree that the choices before you are many, which makes it a challenging experience. For starters, the wide variety of materials can be a bit confusing. In the past, there were just different kinds of wood. Today, wood is passe. Busy lifestyles require materials that are light, low maintenance and sturdy. So, the market has come up with steel, wrought iron, fiber and so on. So, where does cast aluminum furniture stand in the melee of new age materials? What are its advantages? Read on.

    Cast aluminum has several advantages:

    -Lightweight: Pieces of furniture made from aluminum are light enough to be carried from place to place at will but strong and sturdy enough to stand firm.

    -Durable: Aluminum is famous for its resistance to rust and corrosion. In fact, it is even used in spacecrafts and rockets because of its durability.

    -Designs: Aluminum has evolved over the years. In the past, aluminum was used only for a select number of items like folding chairs. Today, the technique involved in making cast aluminum makes it possible to create several designs. Intricate detailing is one of the most attractive features of cast aluminum furniture. Thus, fresh designs and minute details come out all the time.

    -Weather proof: Aluminum weathers well. It can withstand different ranges of temperature. Heat, cold, rain, sunlight and salt air do not affect the material. Therefore, it is ideal for outdoor spaces where furniture is exposed to the elements.

    -Maintenance: For people with busy lifestyles, maintaining furniture in good condition with minimum work is a top priority. Aluminum furniture does not require much work. Wiping the piece regularly ensures that it is clean. Once in a while, you can hose down the pieces and they are as good as new.

    From the properties listed above, it is obvious that aluminum furniture is hardy, sturdy and durable. As such, it is best suited for a patio or a garden, even though it sits just as well within the house. Unlike wrought iron furniture (which is often compared to aluminum), there is no fear of rusting or chipping. Unlike furniture made of wood, aluminum is easy to clean and lightweight.

    Outdoor furniture made of aluminum could be cast or frame furniture. Cast furniture is made using moulds. These pieces are elegant and attractive. Frame furniture has frames as well as a mesh back. The frames may be hollow or solid. These pieces are less expensive when compared to cast aluminum furniture.

    When compared to wood, cast aluminum furniture is not expensive. However, when these pieces are manufactured by skilled craftsmen, as opposed to being machine made and mass produced, the cost goes up because of the quality of the work involved. The cost also depends on the weight of the furniture. Look for warranty on the pieces you buy in order to enjoy maximum returns on your investment.

    So, if you want outdoor furniture that looks good, weathers well and does not burn a hole in your pocket, cast aluminum furniture is the best option for you.

  • Comparing the Watts Premier Recirculating Pump to the Metlund D’Mand System

    The Watts Premier Hot Water Recirculating System

    According to Watts, the Premier Recirculating system gives you hot water instantly at every faucet. Here’s the quote from their website: “Watts Premiers Hot Water Recirculation Pump brings convenience and saving to your home, giving you hot water instantly at every faucet, when you need it.”

    Technically that’s not really true…

    A luke-warm water circulating system

    The Watts Premier system is what I like to call a luke-warm water circulating system. The system consists of a valve for placement under the sink, and a pump located at the water heater. The pump creates a pressure difference between the hot faucet and the cold faucet.

    The valve connects between the hot and cold faucets, and when the temperature drops to below 98° water flows through the valve bringing the heated water towards the sink/faucet/valve installation.

    When the valve senses a temperature above 98° the valve closes and the flow stops. In other words it operates identically to a traditional temperature controlled circulating system, except instead of hot it circulates warm water, and of course, uses the cold water line as the return line.

    Wasting energy

    The water may not be hot, but it is much warmer than with no premier system, consequently your water heater will have to consume more energy to keep the water in that big heat exchanger you call your plumbing system warm.

    One nice thing about the Watts pump is that you can place a valve under every sink if you wish, and get instantly warm water to any or every fixture. However, you will at the same time increase the energy consumption of your system.

    Won’t work with tankless water heaters

    The pump is very small and does not consume much energy, however as a result it can’t pump much water either. It’s unlikely that the Watts Premier will be able to turn on even a small tankless water heater. According to the pump curves on the Watts website the pump cut-off pressure is about 1.5 psi.

    Watts uses a Grundfos UP15-10SU7/TLC pump with a 1/25 horsepower motor which consumes 25 watts. The pump runs continuously, so running it for say 16 hours a day would consume 25 watts/hour x 16 hours/day x 365 days/yr = 146,000 Watt/hours per year in electrical energy consumption. That’s 146 kWh and at say 13 cents per kWh would be $19.00 per year. This would be substantially less than the energy lost due to circulating warm water.

    The hot water will of course arrive more quickly than if the pipes were allowed to cool down completely because being colder, they would suck more heat out of the oncoming cold water as it flowed to the faucet. But it certainly can not be called “Instant”.

    The listed price for the Watts Premier system on its website is $225.00

    The Metlund D’mand Pump

    The Metlund D’mand system is a demand type hot water delivery system. It only pumps the water to the fixture when you “demand it” by pressing a button. The D’mand pump mounts under the sink, and connects to the hot and cold water supply valves like the Watts valve. A power outlet is needed to plug the pump into.

    When the button is pressed the pump begins pumping the water to the fixture returning the cooled off water in the hot water pipes back to the water heater through the cold water pipes. When the pump detects sudden increase in temperature it shuts off so hot water does not get into the cold water line.

    No wasted energy

    Since all the pump does is fill the pipes between the fixture and the water heater with hot water just as you would do by running the faucet, you don’t use any additional energy from the water heater with the system. Since the pump runs for a very brief time, it uses far less electricity than the Watts pump, about $1.00 per year.

    Works with any tankless water heater

    Some models will work with tankless water heaters. Since tankless water heaters typically take 10 to 20 seconds longer to get water to the fixtures, the Metlund pump is a very nice accessory for any tankless water heater, gas or electric. You get your hot water very quickly with no additional energy penalty and you save a lot of water.

    The Metlund pump models range in price from about $350 to about $750 retail price.
