HHO gas generators, fuel cells and car kits can help increase gas mileage. As gasoline or petrol spirals out of control you may be looking at gas alternatives to help reduce costs of operating a vehicle. What if there was and HHO gas plans were available for a car or truck and worked with diesel fuel?

HHO gas has also been called browns gas or hydroxy and has been used for welding applications. HHO gas is one of the best methods to improve gas mileage. HHO generators are sometimes called hydrogen cells or hydrogen on demand but actually produce two gases; oxygen and hydrogen. What you should expect is less pollution from the exhaust of your vehicle.

HHO gas is produced from a process called electrolysis which converts water to hydrogen and oxygen. You probably have seen the HHO car on the news and used for welding but the point here is you get a lot of energy from water with this process and end up with a hybrid water car. You will be supplementing you petrol or gas which should result in increased mileage.

HHO gas should help you see savings of 15 – 40 % or in some cases more including possible increases in horse power and acceleration. Did you ever see this from you favorite gas supplement? You may find Free HHO plans but only the best plans should be used because they often have the detail and pictures you need to properly install the device under the hood of your car or truck.

An HHO generator or car kit is easy to build and should make a nice day or weekend project. A HHO car kit will easily fit under the hood of most cars or trucks and should only take a few hours to install. Once installed it only takes a few minutes of maintenance a month to check the water and catalyst.

It is not uncommon to see free HHO gas plans missing a few details. The best HHO generators plans will show you in detail and have a parts list with pictures and step by step instructions. Very little engine modifications are required. Avoid spending hundreds or thousands on a commercial HHO car kit do it for much less with a good set of plans.

The economy has everyone in a position to look for ways to save money. Well this is one time that you can save money by spending money. Go out and look at some 50cc scooters and after you spend that small upfront investment, you are going to be amazed at how much extra cash is in your bank account.


As the cost of gas goes up, filling that monster that you drive around in is costing you a small fortune. Figuring that the average car gets about 20-25 MPG, you could be filling up your tank as many as 3 or 4 times a week. At $50 or more a fill, it gets pretty pricey. Wouldn’t you rather fill up your ride once a week and only spend about $15 to do so? With a 50cc scooter, you are going to get anywhere from 80-100 MPG and that means a lot less money being spent at the pump.

How aggravated do you get when you cannot find a parking spot anywhere? Maybe it is a quick run to the store or you are just going over to a friend’s house. If you live in the city, you may be parking blocks away and possibly even have to pay for your spot. Do you realize how small of a space a 50cc scooter can fit into?

Another great thing about the 50cc scooter is how easy they are to weave in and out of traffic. You don’t have that luxury when you are driving around in your BMW. You just get to wait in that long line like everyone else and watch the minutes and hours tick away on your watch. Wouldn’t it be nice to get some of that time back?

While these are some of the reasons, there are plenty of other ones as well. Think about the lower insurance rate that you are going to have to pay and how about the time that you will save because of some of the things we mentioned above. Lose your frustrations and save a few bucks in the process by merely traveling around the city on a 50cc scooter.

Underwater welding techniques are most commonly used in executing marine engineering projects such as installation of oil and gas rigs. Underwater welding is mostly related to welding work pieces made from different types of metals such as steel, aluminum, copper, and others.

Underwater welding can be classified according to the type of equipment used and the type of processes followed. The most common underwater welding process is known as manual metal arc welding (MMA) which has the advantage of being relatively insensitive to depth. This makes it the most suited technique for undertaking deep-water repair activities.

Cofferdam welding involves the use of a rigid structure to house the welders, which is sealed against the side of the structure to be welded. Another type of underwater welding technique is commonly known as Hyperbaric welding in which an enclosure is sealed around the structure to be welded, and is filled with a gas (commonly helium containing 0.5 bar of oxygen) at the prevailing pressure. This welding technique is often combined with MMA (SMA), TIG (GTA), or FCAW for effecting high integrity welds, particularly for deep-water welds, including tie-ins in pipelines and risers in the oil and gas industries.

Underwater welding techniques are used for welding steel pipelines, other offshore structures, submerged parts of large ships, and underwater structures supporting a harbor. Welding in depths of 500 to 1000 meters generates high weld metal diffusible hydrogen, which can increase the risk of hydrogen-assisted cracking. This can be prevented with the use of electrode coating formulations and improved power source technology.

Underwater welding techniques can be dangerous if proper procedures and equipment is not used. An underwater welder faces the potential risk from electric shocks and from nitrogen introduced into the bloodstream during exposure to air at increased pressure. Underwater welding safety measures include emergency air or gas supply, stand-by divers, and decompression chambers to avoid decompression sickness following rapid surfacing after saturation diving.

Arc welding machines and stick welders have been around for many, many years. According to wikipedia.com the first recorded use of an arc welding machine was way back in the early 1800's.

Slowly over time the development of the stick welder and arc welding machine were greatly improved. The evolution of mankind demanded better ways of joining metal together.

Anyone who has even remotly looked into welding has most likely heard of, or seen an arc welding machine.

To understand the stick welder you need to understand that you are dealing with electricity. All electricity that is supplied to your workshop, shed, garage or house is what is called AC power.

AC power is short for "alternating current". In english this means that the power coming out of your wall socket will go from positive (+), to negative (-) really fast over a short amount of time.


In my country of Australia we are on 240volt AC power at 50Hz. So this means that my power will go up to 240V positive, then back down to negative 240V at 50Hz. Hz is Hertz, which means that the power will go from +240V to -240V at 50times per second. Pretty quick huh!

On a side note this is why the light bulbs in you house do not flicker, as the change from positive to negative is so fast. But if the Hz was only say 5 instead of 50 you would probably see the light globe flicker on, off, on, off.

The majority are DC output.

DC is direct current. That is the power does not go up and down like a wave but rather in just a straight line.

This gives us a consistent current power source of DC power which is ideal for arc welding.
Here is a video that I did about Arc Welding Machines and their basic setup.

It is much easier for me to show you in a video rather than you having to read through page after page of welding information.

In the video I show two different types of arc welding machines. The first machine is the type of welder that you would buy from the local hardware store for a hundred or so dollars.

The second machine is a more heavy duty industrial machine that is physically bigger and will offer more power output for bigger welds, and it has a higher duty cycle. The second machine has a high voltage output option as well.

In the video I go over how to attatch the welding leads, how to adjust the welding power output, and how to put the electrode into the "stinger".

Truck bed covers are often referred to Tonneau covers. "Tonneau" is a French for "cover" and since the 1970s has been used to describe the cover that goes over the pickup truck's bed. This cover is used to protect the contents of the bed from wind and rain, and to secure it away from thieves. But the benefits not only stop there. They can improve the look of your truck and improve the drag on your vehicle, saving you gas.

When the truck bed is uncovered it pulls the air downwards which is poor aerodynamics and means when you are traveling at high speed there will a lot of drag on your truck. The noise associated with this drag can be very loud. By covering your bed, a truck bed cover can reduce the drag and associated noise meaning that your truck will consume less gas when you are on a long trip consisting of high speeds like on a highway or freeway.

Truck bed covers come in three different types.

Hard truck bed covers are made from fiberglass, hard plastic or aluminum. These types of covers are typically smooth and are colored the same as the truck itself. Most are hinged so that you just need to lift up one end to get access to whatever is in the tray. These are the most expensive types of covers.

Soft truck covers are made from toughened fabric like material and have bows to keep their shape under snow and water. They attach to the truck tray with snaps, Velcro or a groove and tongue system. Some can be rolled up or others are hinged lid models.

Retractable bed covers are a popular choice. When you need access to the tray they roll up inside a canister that sits at the back of truck.

Automotive scan tools are actually small computers run by programs like all other computers. Computers themselves, when demythologized, emerge from the fog as remarkably simple devices that think in 1's and 0's. They're not that smart. The true "intelligence" and complexity of any machine ALWAYS lies with the program within. When purchasing automotive scan tools and software, evaluate first the frequency with which you either personally or professionally encounter technological and mechanical change, and choose automotive scan tools with software upgrade options that will adapt an existing unit to new industry developments without requiring unit replacement with each advance in technology.

Pro-link scan tools and software offer you countless benefits in application and upgrade capabilities. Keynote features range from diesel engine fault ECU input monitoring, programmable EEPROM data, and comprehensive database storage of all proprietary OEM specifications. Pro link scan tool software packages offer comprehensive diagnostics on Detroit Deisel DDEC I/II electronic engine controller systems, Bendix ABS and ATC systems, Volvo VED 12systems, and even Mack Trucks with V-MAC II and Marine engine troubleshooting for boats! Each of these Pro link software packages proactively anticipates the many complex problems that can arise from increasingly complex technology. You can also expect to benefit from specific diagnostic capabilities such as ECU input and output status monitoring, displayed data parameters in either English or metric readout, user-created custom data lists, and clear diagnostic fault codes and compression testing options.

The first time buyer normally asks the obvious and intelligent question, "When do I know it's time to upgrade my pro link scan tool software?" Need and circumstance determine upgrade requirements more than any generic feedback can advise. Personal vehicle owners normally upgrade their automotive scan tool with new software when they purchase their next vehicle. Professionals face more variables and greater frequency of upgrade because they service multiple vehicles of diverse make and model, and they face industry changes every day as a standard course of business.

Each time the government requires a new safety feature and issues a set of safety compliance standards regulating its performance, vehicle technicians will need to upgrade pro-link scanning tools with software that can effectively diagnose safety devices and proactively identify potential malfunctions. If you run a service shop, make especially certain that your automotive scan tool software reflects the latest safety compliance laws. Not only must you observe these standards due to governing authority, but the problematics of insurance can only harm your business if you neglect to upgrade your software and later find yourself held liable for an accident outdated technology failed to prevent. Please do not assume that this cannot happen to you because it already has to someone in the world today. It does not, however, have to repeat itself in your personal world or the lives of your clients.

It simplifies life and better serves outcome to simply upgrade automotive scan tool software anytime you learn of a feature that specifically addresses a change or new type of problem you encounter. Automotive scan tool software loads into the unit via CD or a plug and play card similar to software and expansions cards on PC's and laptops. The process is simple. The results will astound you and serve you well.

The MAX-LOCK rear differential upgrade. With over 200% more surface area and 60% more lock-up, the EVO will now rotate better when you get on the throttle versus understeering upon exit of a turn. Think Dukes of Hazard.

How does it drive? AWESOME!!! Finally you can manhandle the EVO and it responds like it should have in the first place. With the increased lock-up the EVO will no longer understeer and actually require some counter steer upon exit much like a RWD car but with the benefits of AWD. With the MAX-LOCK you can use conventional suspension settings and focus on setting up the car for max grip instead of doing crazy things like zero camber, stupid stiff rear sway bars, way too much spring rate and 60psi of rear tire pressure.

Will this make the EVO quicker around the track? YES!!! Autocross EVOs are knocking over a second off every 60 seconds of track length and road racers are achieving quicker lap times due to the ability to use the whole track versus a narrow line and this comes in real handy for those who are racing on a road course with traffic. Another benefit is longer front tire life because you don't have to crank the steering wheel to the point of the front end washing out just to get the EVO to stay off the grass on the outside of the turn. We aren't saying that this upgrade is the end all to making an EVO power-slide out of the turns like a Tokyo drift car but it has proven itself time and time again to be a worthwhile no BS upgrade on the stock suspension or the fancy 4-way adjustable stuff.

How well does it hold up for road racing? How long the differential holds up will mainly depend on your suspension set-up, driving style and track conditions. People who are competively racing in SCCA T2 are getting two seasons worth of use before inspection is required while the daily drivers are reporting that the rear differential is still working strong. Based on my findings, I would expect it to last many years in a daily driver before any service is required.

Turn around time is quick, about 2-3 days.

This service includes:

* all new friction plates
* modified side sheaves
* magnaflux inspection of ring & pinion
* shims
* seals
* adjustment of ring & pinion (if necessary)
* and a fresh painting so it looks like new again.

Background

Popularized in the 1920s and used heavily ever since, the bulldozer, commonly termed a dozer, is a clear offspring of the crawler tractor. Used in conjunction with other earthmoving vehicles, the bulldozer is a powerful and necessary tool utilized in almost every construction site in the world.

Primarily manufactured in the United States by Caterpillar, John Deere, and Case Tractor Company, the bulldozer provides for many industrial applications such as construction, waste management, and farming.


Raw Materials

Bulldozers and crawlers, characterized for their immense blade and versatile track, are comprised of many structural, hydraulic, and engine assemblies. The core body of the bulldozer, consisting of the mainframe and undercarriage, is primarily fabricated from low carbon structural steel plates and a giant casting. The cab contains many glass, rubber, and plastic components which enhance the ergonomic feel of the machine. Supplying the power for the dozer and its various systems, the engine contains many high strength steel parts, which endure high operating temperatures. The other necessary components, the blade, power train, and various systems components, are formed from structural and high carbon steel. The track, which is fashioned from many standard grade steel links, adds to the already tremendous weight of this mostly steel machine. Once the dozer is filled with fuel, hydraulic fluid, coolant, oil, and other types of fluids, its weight increases by several hundred pounds. Decorative trim, decals, and paint complete the dozer's aesthetics and add distinctive appeal.

Design

Two distinct features characterize the bulldozer, the long, vertical steel blade in the front of the vehicle and the rotating twin tracks, which facilitate the bulldozer movement. The blade, which can weigh up to 16,000 lb (7,264 kg), is useful for pushing material from one spot to another. Perpendicular to the ground, the curved blade is attached to the frame by a long lever arm that can tilt and move up and down under hydraulic power.

The familiar flexible track of a bulldozer is widely utilized in industrial machinery equipment and military tanks. In fact, some farming tractors are considered to be cousins to the bulldozer, since they also utilize the flexible track instead of standard wheels. Steel links, sometimes more than 2 ft (61 cm) in length, are connected with lubricated pins to provide for fluid motion and stability. Moreover, many bulldozers have incorporated an elevated sprocket design which suspends the power train, and thereby, improves its reactivity to the terrain. The diesel engine of the bulldozer can generate anywhere from 50-700 horsepower, so rough terrain and steep slopes are not a problem for this machine.

Mounted above the flexible track, the operator cabin contains the complex hydraulic mechanisms, which power the blade in a limited vertical range. The cabin design has seen many improvements in operator comfort and ergonomics and has provided for many improved automotive features, such as air conditioning, AM/FM radio, automatic seat adjustments, electronic controls, and systems-monitoring equipment. In these areas of dozer design, the engineering and research that precedes the manufacturing mimic the automotive industry in many ways.

The power train includes the transmission, differential, and gears that rotate the track. Coupled to the engine crankshaft, the power train will transmit power from the engine to the elevated sprocket gear. Many new bulldozers have independent steering, which allows each sprocket to rotate at full power even while one is rotating slower as the dozer is in a turn. Other innovations in recent years include differential steering, hydraulic power, and planetary gear transmissions.

The Manufacturing
Process

The bulldozer, a seemingly endless network of bulky steel components, complex systems, and intricate assemblies, begins its manufacturing process on an assembly line. Prior to final assembly, much machining, fabrication, and sub-assembly must take place. Manufacturing begins with engineering prints and drawings taken from a computer-aided drafting (CAD) program that outlines the method of construction for each component part. Some of these programs can be used to set up machines for which most of the manufacturing will take place, that is, in fabrication cells, large machining centers, and sub-assembly lines. This is called computer-aided manufacturing (CAM) and is used to produce the components and assemblies that join together on the main line. Some of these components will then undergo heat treating, annealing, or painting after their respective fabrication cell, sub-assembly line, or machining center step. An overhead conveyor system will then transport the pieces through the rough paint or powder coating operation and lift them to the main assembly line, where they arrive in time to be assembled. These pieces may also be transported by lift truck, hand cart, or floor conveyor to arrive at the staging area before they are assembled to the bulldozer.

Mainframe core

* The mainframe core, which forms the rigid inner body, is cut from steel plate and structural shaped, so that it easily resists high impact shock loads and torsional forces normally incurred by the dozer. The main structural skeleton, formed through the welding of steel plates to machined casting, is comprised of two boxed-in rail sections connected to the main casing. The fabrication is normally performed in a fabrication cell, where the burned plate arrives ready to be mounted into fixtures and manually or robotically welded to the stationary central casting. Far too massive to be lifted by hand, the frames are then transported by overhead crane to different stations, where steel mounting blocks and trunions, or cross members, are welded on as a support for the other components of the bulldozer. Once completed, the frame is rotary sanded on all plated surfaces and sent to the paint booth and the main assembly line.

Diesel engine and transmission

* At the assembly line, the independently manufactured diesel engine and transmission join the mainframe. The engine is usually purchased completely assembled as it is a complex system with machined components that can be used in many different vehicular applications. In fact, the engine (which has been subjected to various performance tests) is certified to operate on arrival. The engine mounts in the front of the bulldozer; however, it is connected to the transmission, which sits in the back. The two are connected by a long shaft and supported by couplings and bearings. The transmission is then connected to a series of gears and differentials to comprise the rest of the power train. By mounting on pads previously welded to the frame, the engine/transmission assembly can be bolted directly to the base on the main assembly line.

Radiator and additional assemblies

* On the front of the bulldozer, an engine casing is mounted to support the radiator and hydraulic lifting cylinders. The radiator, another finished assembly, will then sit between the engine casing and mount to the front drive shaft. Connections can then be made to attach water lines from the engine to the radiator. Additional assemblies for the hydraulic, lubrication, cooling, and fuel systems are also constructed at other locations and purchased as a finished assembly ready to be fastened directly to the engine or base. These include hydraulic lines composed of tubes, hoses, and fittings pre-assembled and mounted on the engine or frame and connected to pumps, valves, tanks, and cylinders, each of which can be brought to the main assembly line as a finished component. Fuel, exhaust, hydraulic, and coolant lines also arrive ready for assembly and mate to other finished components. Many of these components and sub-assemblies must be inspected and approved for dimensional compliance at an incoming inspection station prior to assembly.

Large component assembly

As the entire assembly of the frame, engine, transmission, and line groups move along the main production line, larger assemblies and components are brought in by overhead cranes, overhead conveyors, automatic guided vehicles (AGV), or lift trucks. These components include the cab, larger hydraulic cylinders, undercarriage components, and the front blade.

* The cab, which can also be purchased as a finished assembly, is usually manufactured at a different facility and shipped for assembly. Usually complete in its array of electronics and controls, the cab will be mounted on steel blocks or pads located on the dozer frame. After mounting, connections will be made to the various controls, and power can supplied to the fully functioning cab.
* Concurrent with the engine/transmission mounting, the undercarriage, composed of tubular roller frames, drive sprockets, and bogey independent suspension rollers, will be mounted on the frame and assembled to the drive train. The axle assembly will turn the outer sprockets that rotate the track, allowing the vehicle to maneuver. The sprockets, typically 2 ft (61 cm) in diameter, will fit into the track with case hardened teeth, which move the track as they rotate. In many manufacturing operations, the undercarriage can be machined, assembled, and painted in the same facility as the main assembly line, but various smaller components like bearings and lubrication bushings need to be outsourced to other facilities or outside contractors. The track, which is often pre-assembled from machined steel links, can be fitted around the drive sprockets, rollers, and front/back guide gears only after the engine/transmission and undercarriage components are in place. The exhaust stack, attached directly to the engine, is supported by brackets and flanges at its base.
* After the cab controls are connected to the engine and hydraulic systems, prefabricated cowlings or body panels are mounted directly on the base frame to cover the engine, transmission, radiator, and fluid lines. The body panels are designed to fold back, making the inside of the dozer easily accessible for regular maintenance. They are assembled into hinges already fastened to structural supports. Tooling and storage compartments may also be built into the dozer once the lines have all been connected. Deck plates lie around the cabin and are welded to support brackets.
* The front blade is attached to hydraulic cylinders, which can position the blade at different angles of tilt. The cylinders, each comprised of a hardened steel piston inside a honed cylinder, are attached at one end to engine casing in the front of the bulldozer to move the blade vertically. Initially in the assembly process, the cylinders are left unattached at the one end until the roll formed steel blade is assembled, and then hydraulic lines can be fitted and tightened. The lower end of the blade is attached at two joints with large steel pins which rotate and tilt the blade with two more cylinders. Arms extending from the undercarriage are attached to the blade and then are assembled along with the other undercarriage components.

Final assemblies

* Once the dozer has been outfitted with its primary components, more hoses, electrical lines, and fluid lines are attached at fitted connections. Items such as the batteries, which are connected to the starter on the engine, lie underneath a cowling in a compartment located near the engine. Lights, one of the last items installed on the dozer, will be placed in a number of different areas and connected to their power source. In addition, hand or guard rails and foot pegs are bolted on the frame which complete main line assembly.

Paint

* At Caterpillar's Track-Type Tractor (TTT) division located in Peoria, Illinois, Caterpillar bulldozers and crawlers use the same paint and final prep lines as many other tracked vehicles. Applied manually with spray guns, the final paint booth will deliver paint to any area not blocked off with paper or plastic wrapping. The paint dries quickly and the bulldozer will move to the next station where decals and trim are applied by hand templates.

Fluids

* Various fluids are added, and the vehicle is then sent to a testing station where the operation of all systems is mechanically verified and recorded. The vehicle is transported from the manufacturing site to a staging area for customization and shipping. The completed bulldozer is shipped on a flat bed trailer and is ready for field operation upon arrival.

Byproducts/Waste

Waste produced by the manufacturing operations may include machining coolants, oils, parts-cleaning detergents, paint, and diesel fuel. The United States Environmental Protection Agency (EPA) places strict regulations on manufacturers to mandate that these potentially harmful liquids are disposed of in a proper manner. Companies contract a waste removal firm to recycle most of the liquid waste. Metal chips and shavings are recycled and sold to scrap dealers in an effort to reduce waste.

The Future

Bulldozers consistently undergo component design modernization efforts, and innovations appear inevitable. Improvements in cab comfort and diesel engine efficiency will probably be the driving force for many of these changes, while design and operational changes will be limited to individual components. In spite of the fact these enhancements in both the manufacturing process and streamlining of material flow will probably not change the face of bulldozers, costs may improve. Therefore, as a useful member of any earth-moving team, the bulldozer will continue to serve a unique purpose in building construction, waste management, and many industries.
