Orbital air sander

For any sanding or polishing jobs that require an excellent finish, on almost any surface, an orbital air sander is the tool that you need. Orbital sanders have quickly become the tool of choice for anyone wanting to either prepare a surface for painting, or alternatively, to get a superb finish afterwards. An orbital air sander is a flexible and easy to use air tool, which is considered essential for professional auto body repair jobs, and is also the kind of equipment that every hobbyist will want to have in their toolkit in order to ensure that they can do a great job. An orbital air sander features a sanding pad that moves in a random manner around a specific center point. It is this random movement that is the key to the success of the air tool. Rather than with traditional sanding devices such as a belt sander, where the tool leaves a mark on the surface and can lead to an uneven finish, with a random orbital air sander, the finish is even over a much wider area, meaning that the finish that you can expect is much better and smoother. The combination of a circular and random action of the sanding disc on an orbital air sander means that it is able to sand in any direction, cover a larger area relatively quickly, and avoid concentrating too much sanding action on one area. This means that the finish will be more even than with a belt sander or even old style orbital devices that did not have a random aspect to their movement. You can add different sanding discs to an orbital air sander to ensure that it is properly set up for a huge variety of different jobs. From heavy duty sanding paper for tough jobs through to buffing cloths in order to get a final polished finish at the end of the job. With most orbital air sanders, changing the disc takes just a few seconds, allowing you to get a variety of jobs done a lot quicker. Perhaps the most immediately obvious application that an orbital air sander can be used for is in preparing an area of auto body for painting. You would start off with a fairly rough grade of abrasive paper in order to strip back the paint and leave bare metal. Within a couple of seconds, it is possible to change to a finer abrasive in order to smooth the metal out and get it ready for paint. After each coat of paint, an even finer abrasive can be used in order to get a great finish, before the disc on the orbital air sander is changed for the final time and replaced with a buffing cloth to get the perfect finish. Pretty much every power tool manufacturer produces their own version of the orbital air sander, and they range in price from basic inexpensive models that are useful for anyone wanting to do small jobs around the house right up to high quality professional air tools that are designed for the professional auto body shop, and will provide reliable service for years.

The hybrid van what does it have to offer

A family of six going on a trip to a resort about two hundred kilometers away from home will either take the bus, if one's available, or take the family van and gobble up around 20 liters in diesoline. Imagine the pollutants that family van emits! Not anymore. These days, that same family can bring a hybrid van that is not only safe, but more so, cleaner and healthier, both for the environment and the passengers. Capitalizing on the practicality of combining gasoline and electricity in hybrid technology, hybrid vans can offer other features that will definitely be a come-on for the environmentall-conscious. What does a Hybrid Van have to Offer? Before making that decision to go for a hybrid van for your family or office, let us take a look first at what these vans of today and of the future have to offer. Take a Toyota Estima Hybrid Van for example. It combines a four-cylinder engine with two electric motors. The electric motors are placed one in front and one at the rear of the vehicle, making a four-wheel drive arrangement. Without the complex transmission shafts and all of a four-wheel drive, the hybrid is lighter, thus more fuel or electric efficient. Improving on the designs and features of the heretofore Grandias and Hi-Aces, Estima Hybrids bring a new meaning to sleek and environment-friendly. A handsome van, this hybrid takes into consideration the mobility needs of families and even office groups or sports teams of all ages and abilities, while also ensuring that high mobility does not take its toll in the environment. Hybrid vans may run on combination fuel-electricity technology or on purely-electric mode depending on the batteries' charge. And running on batteries mean no more carbon dioxide emissions. No toxic substances are released to the atmosphere, not to mention to the van's interiors. One is assured that one's kids do not inhale any dangerous amount of carbons in and out of a hybrid van. Hybrid vans also incorporate smart features like humidity monitors for air conditioners, and this reduces the use of the air-con whenever possible. This only translates into fuel and battery-life economy. Why Go for a Hybrid Van? Traveling with your family or your friends and officemates, you want the trip to be as safe as possible, of course. Hybrid vans incorporate safety features, standard and state-of the art, to eliminate traffic accidents and injuries or fatalities to passengers. While seatbelts and air bags are standard issues, hybrid vans are going for radar-based features that ensure no crash accidents happen. Simplicity amounts to safety, too. With electric motors, complicated and oftentimes heavy mechanicals are done away with. With lighter vehicles, stability and balance is better maintained. And then again, you want to contribute to the global drive to protect and preserve the environment, even while going on that family vacation. Hybrid vans are a great contribution to the effort, as they go around and away on minimal fossil fuel, thus making the atmosphere cleaner. No more carbon dioxide, volatile compound emissions, just pure mobility. Health-wise, hybrid vans ensure this not only to the pedestrian but to the driver and passengers, too. Low emissions, smart air conditioners, streamlined aerodynamic designs, mobility balance, all these combine to ensure not only freedom of movement but freedom from harmful substances and unnecessary pressures of road travel. Gone are the days when one had to bear the fuel plumes overtaking the car's air conditioner, or stiff bucket seats that rub one's shoulders and back thin. The road travelers nowadays consider the vehicle their homes away from home. Manufacturers are looking at this need to create vehicles that are cozy and comfy, offering the luxuries of home, yet not forgetting the safety factors. Who would want to feel unsafe in one's home? With a hybrid van combining feature with facility, safety to the user and the pedestrian is ensured - where else can one get the best of both worlds? Go hybrid now!

Diesel fuel... are you getting what you paid for or buying a problem

: Diesel engine designs striving to increase engine performance have made great advancements in engine fuel delivery to the combustion chamber. Today’s diesel engine is quieter, smoother, and more powerful. But today’s diesel engine owners are overlooking one important factor. The quality of today’s diesel fuel has not advanced at the same rate as the engine improvements. Diesel fuel begins to deteriorate as soon as it is produced. Within 30 days of refining, all diesel fuel regardless of brand, goes through a natural process called re-polymerization and oxidation. This process forms varnishes and insoluble gums in the fuel by causing the molecules of the fuel to lengthen and bond together. These components now drop to the bottom of the fuel tank and form asphaltene also known as diesel sludge. The fuel begins to turn dark in color, smell bad, and in most cases causes engines to smoke. The engines smoke because some of these clusters in the early stages are small enough in size to pass through the engine filtration and into the combustion chamber. As these clusters increase in size, only part of the molecule gets burned. The rest goes out the exhaust as unburned fuel and smoke. With increases in cluster size they begin to reduce the flow of fuel by clogging filters. The filters only address the symptom and not the cause. It is estimated that eight out of every ten diesel engine failures have been directly related to poor quality and contaminated fuel. The build-up of contaminates in the fuel systems and storage tanks can quickly clog filters, thus resulting in engine shut down, fuel pump wear, and diesel engine damage. Understand that most fuel has some amount of water in it from either condensation or vents. This threat requires that we realize the added burden placed upon diesel fuel as opposed to gasoline. Gasoline acts as a fuel only. Diesel fuel, on the other hand, also must cool and lubricate injection system parts. These parts are engineered to very close tolerances - up to 0.0002 of an inch - and any contamination means rapid part wear. Water displaces the diesel fuel. When the fuel is displaced wear occur because lubrication is now absent. Water that enters the combustion chamber results in even more serious damage. When it comes in contact with the heat of the combustion chamber (in excess of 2000 degrees F), it immediately turns to steam and often explodes the tip of the injector. Water causes corrosion of tanks, lines, injectors, and greatly reduces combustibility. Other areas of concern include the producing more exhaust emissions and effecting EPA standards. Bacteria also present a serious problem. Bacteria feed on nitrogen, sulfur, and iron that may be present in the fuel or tank. Then there are algae. There are absolutely no algae in diesel fuel. You may have fungus and microbial contamination but no algae. This is a misnomer for diesel sludge. So if you have a diagnosis of ALGAE and add a biocide, you have done two things, 1) found a mechanic that is wrong and 2) done nothing to fix the problem. Why is there so much bad fuel? The number one reason is due to the increased popularity of diesel power and the accompanying increased demand for more diesel fuel. There was a time when diesel fuel remained in the refinery storage tanks long enough to naturally separate and settle, allowing the clean fuel to be drawn off. Now with increased demand, diesel fuel never remains stationary long enough for settling, and the suspended water and solids are passed on to you, the user. The change in refinery techniques is another problem. In order to get more products per dollar; diesel fuel is now being refined from more marginal portions of the crude oil barrel. This results in a lower-grade product that is inherently thicker and contains more contamination. Thirdly, current fuel distribution methods also have a negative impact on the condition of the fuel at the time of delivery. In many cases, brokers control fuel sales to major distribution terminals and determine delivery dates. There is no telling how long that fuel has been in the distribution network and how many times it has been transferred. Seldom do these distributors filter the fuel as they transfer it. The solution: Multifunctional diesel additive packages and hardware. For your single vehicle or fleet the improvement of fuel quality by the use of additives and current technology is always a good choice. Many diesel fuel additive packages address the key issues with respect to fuel performance; some improve fuel economy, increase lubricity, improving cold flow, and improve cetane number. And some only address the issue of rust and corrosion, but all should be considered. Most diesel fuel additives contain combustion improvers that release oxygen during the compression stroke. This allows combustion to start sooner, providing for a more complete fuel burn. A more complete burn provides all the power your fuel and engine is capable of producing. As combustion improvers and you get a smoother running engine, an increase in horsepower that improves fuel economy and the reduction in black smoke emissions. Cetane is a performance rating of a diesel fuel, a higher cetane number or cetane rating indicates greater fuel efficiency. The fuel’s cetane influences, duration of white smoking after start-up, drivability before warm-up, and intensity of diesel knock at idle. Increase the cetane number of a fuel and you have improved performance. In diesel fuel systems, the fuel provides lubrication for the fuel pump and injectors. A fuel with poor lubricity can cause excessive wear and premature failure of these components. Improve lubricity and extend engine life. Diesel fuels have pour points (the lowest temperature at which an oil or other liquid will pour under given conditions) within the range of normal winter temperatures. As a fuel approaches its pour point, paraffin in the fuel form wax crystals that prevent it from flowing. Flow-improver additives modify the wax crystals, lowering the pour point of the fuel and give better cold weather performance. For on-sight storage tanks other issues must be looked at. On-sight storage tanks always have a small amount of the first gallon of fuel ever put in them, unless it is drained 100% and cleaned. So adding new, fresh fuel always has a bit of the bad added to it every time fuel is purchased. Diluting the bad with good over time is a loosing battle. The fuel will always be bad fuel until the core problem is addressed The order of treatment for fuel related problems should always begin with a determination of whether there is water in the fuel and if the fuel has microbes (fuel bugs) in it. Water Paste and Fuel Test Kits can be used for this stage of maintenance. If microbes are detected, then the use of biocides is needed. Biocides have no effect on and will not eliminate the sludge problem. Biocides kill bacteria, that’s all! The water issue should always be remedied first by the use of fuel water separators on the tank or on the equipment. Next a multifunctional chemical additive should be added to improve fuel performance and then if needed a problem specific additive to dissolve diesel sludge and or a rust inhibitor to protect steel tanks. For long-term prevention, the use of magnet fuel conditioners is recommended. These devices continually reverse the re-polymerization of the fuel during circulation and reduce the need for ongoing additive use. All the needed cures are available from Dieselcraft Fluid Engineering at dieslecraft Conclusion There is no good time to find out that your engine won't operate or that half its life span is gone prematurely because of contaminated or poor quality diesel fuel. Since no one can predict a breakdown, the only safe method is prevention. Realize now that you do have a problem, and manage it now, or deal with the unexpected catastrophe and reduced equipment life that comes at the absolutely wrong time and is not in the budget!
