Moving Limits For Pneumatics

Flange is commonly known as the ''jet plane effect'' to the masses, and it's sound has been a popular staple since the 60s. It can be used on any instrument imaginable, from vocals to guitar to drums.

Flange at it's core is simply a delay effect with the delay parameter set at a very small amount. With today's technology, producing this sound manually is easy as pie.

The customization features on modern flanging units is unparalleled. Dialing in a signature flange style has never been so easy, but it's important to understand the functions of each parameter and why it works the way it does.

The common delay setting to achieve flange with a delay unit are 20 milliseconds and under. Instead of hearing the actual signal being delayed, they will blend together to make a ''jet plane effect'' sound. The reason this happens is when two identical signals overlap each other, some frequencies are ''canceled out''.

Let's go over the parameters that are usually on flanging units.

Parameter One - Delay : This parameter changes the time it takes for the second signal to play after the original. Most times the highest setting will not be more than 20 milliseconds, as mentioned above. In some cases, the delay setting can be to to a negative value to create interesting ambient effects as well.

Parameter Two - Depth : This parameter functions as the control for the ''warble'' of the flange effect. That is, the severity of the changes in pitch.

Parameter Three - Width : This parameter is somewhat similar to Depth, but has a noticeable difference to the ear. It controls the speed at which the peaks and valleys of the flange are reached.

Parameter Four - Rate : This parameter controls the rate at which the warbles repeat themselves. The faster the speed, the faster your audio signal will go through the complete flange process.

Parameter Five - LFO : This parameter isn't on older flange units but is found on more recent software flanges. They enable you to alter the output of the wave in accordance to the flange. The four possible settings are sine, square, saw, and triangle.

Parameter Six - Feedback : Now we're talking. Feedback loops the output signal back into the input, creating a possibly infinite amount of noise. This results in many strange effects, especially in higher settings. If you're using headphones, be sure to keep the volume low before you experiment with this parameter.

This concludes the guide to flange. As always, experiment and use your ear!

Pneumatics On The Upswing

The sound, accompanied by a high-pitched shriek as cables move rapidly upon a cable loop system, is somewhat reminiscent of that made by a windmill's blades as they slice through the air. No power is generated, however — this sound is the definition of power consumption, as two giant arms swing thrill-seekers high into the air through the use of huge pneumatic cylinders.

Cedar Fair LLP, Sandusky, Ohio, introduces a new ride each year at its Cedar Point amusement park. The Skyhawk, 2006's edition, is a massive swing, designed by S&S Power Inc., Logan, Utah, which specializes in pneumatically (and sometimes hydraulically) driven rides. Its other Cedar Point contributions include the pneumatic Power Tower and the free-falling hydraulic Frog Hopper, a children's ride. More than 100 of its rides entertain riders worldwide.

Seating 40 people — 10 on each side of two large arms — the Skyhawk swings riders up to 125 ft into the air at speeds of 60 mph or more. The one-minute ride peaks at seven swings, giving riders a chance to look straight up into the sky, out over Lake Erie, or straight down to the concrete below.

This is accomplished, says Cedar Point's Vice-President of Maintenance/New Construction and Assistant General Manager Monty Jasper, with the use of a “ready power plant.” Air.

The ride is run by four 300-hp compressors from Ingersoll Rand, which pump 1275 cfm of air at 120 psi to two double-acting air cylinders that are truly massive — each has a 28-in. bore and 21-ft stroke. The two cylinders, situated on either side of the ride's legs, each contain a 300-lb piston, which generates approximately 73,000 lb. of thrust, said S&S founder Stan Checkitts. The cylinder stroke about 22 ft in normal operation within the 31-ft long cylinder.

Quick-acting, 4-in. valves, operated by 3/8-in. pilot valves, shoot the compressed air into the cylinder. S&S' Tim Jacobi, project engineer for the Skyhawk, adds, “To swing the arm one way, we open the two-position push valve on one side of the cylinder and the exhaust valve on the opposite side. Then we do the opposite to swing the arm in the other direction.” The valves shift from fully closed to fully open in about 1 sec. A computer system monitors the ride and its velocity and commands the valves to open or close.

A single loop of high-strength steel cable transmits force from the cylinder to a sheave that applies torque to drive the swing arm. Essentially, then, the assembly acts as a giant rotary actuator. A sheave at the bottom of the tower acts as an idler, and additional sheaves help keep the cable stable. Jacobi says the cable cannot become slack, which is achieved by pre-tensioning the wire rope. Because it's a loop, the tensions oppose each other. Air flowing into one end of the cylinder increases cable tension at that end but decreases tension at the other end, and the pre-tensioning prevents any part of the loop from going slack.

Pneumatic Cylinders Bounce Back

Pneumatic cylinders perform an array of functions in electronics, automotive, and packaging industries. Their basic function is always the same — linear advancement of loads by attachment to a metal piston, pushed to and fro by columns of air. At some point in every application, however, a cylinder must slow down, stop, and change direction. Exactly how that happens determines how well the cylinder will perform in cycling applications.

Air throttle

When an uncushioned piston reaches one end of its stroke, it slams into the end cap, creating a hard metal-to-metal impact. The impact is often so loud that its exceeds OSHA standards for workplace noise. After the impact, the piston may bounce, during which time, the cylinder's motion is technically uncontrolled. The high amplitude, high-frequency impact can also damage the cylinder, as well as surrounding equipment.

Avoiding such problems and decelerating piston rods in a controlled manner requires external or internal cushioning. External cushioning employs a shock-absorbing mechanism outside the cylinder's body to absorb piston impact. The drawback is that it increases the footprint of the cylinder and adds weight and moving parts. Internal cushioning, on the other hand, operates within the cylinder footprint and tends to be simpler in function.

Here's how internal cushioning works: At end-of-stroke, a piston rod approaches the cylinder end and squeezes air out; a flow vent meters air for controlled velocity. Just before impact, a cushion spear or sleeve jumps into action, blocking the cushion seal and eliminating the exhaust path. The controlled volume quickly decreases, compressing the gas. Exhaust is then metered out even more slowly, through a cushion needle, completely decelerating the piston before it contacts the cylinder end.

The air cushion itself is adjustable, so the volume of air released can be metered during compression. A threaded needle screw piercing an orifice on the end cap provides the adjustment. Turning the screw further into the orifice decreases the amount of air that can escape in a given time. This diminished exhaust creates backpressure for an even more dramatically decelerated piston.

Physics makes it possible

The physics involved in a cushioned air cylinder is relatively straightforward. The laws of physics require that a negative force act on a piston to decelerate it. This occurs when air is squeezed or compressed in the end cap, and can be mathematically understood.

Two things actually prevent pistons from colliding with end caps. One is the deceleration of the piston with an auxiliary (cushion) system. The other is drag. Pistons (and loads attached to them) slow down quickly when — prior to hitting any air cushion — the actuator reaches equilibrium between the net driving and frictional force:

Once the piston reaches the air-cushioned zone, it compresses the controlled volume of air, producing an elevated backpressure. In turn, this provides a negative force component to decelerate the load:

Some assistance

A cylinder that includes an energy-absorbing seal allows for a larger cushion orifice. With this, a piston can travel through the air cushion in one-fourth the time of a conventionally cushioned cylinder. Plus, extended piston seals can accelerate out of air cushions faster. One reason is that the larger cushion orifice doubles as a larger bleed orifice in the reverse stroke, letting air into the cylinder at a faster rate while exiting the air cushion at the other end. Another reason is the seal acts as a compressed spring, providing an initial force of 80 psi to push or accelerate the cylinder.

So, how do we avoid piston and end cap contact, bouncing, and noise, while also maintaining reasonable cycle times? By extending the cushion seal and changing its attachment to the piston. Rubber seals that extend beyond the face of the piston assist in cylinder deceleration. These extended seals are usually made of nitrile-based rubber, press-fit into a machined groove on the piston. As a cylinder completes its stroke, the seal absorbs 80% of the energy, reducing pneumatic bounce, and effectively, noise. In this way, all the cushioning isn't done by the air cushion. Less time is spent draining air, so cycle times are maximized.

The Facts About Air Compressors

Compresses are used for a variety of purposes from powering pneumatic or power tools (like nailers, and staplers) blowing dust and debris off/out of those power tools, or as an inflation device for tires, flotation devices, and etc. Available in a variety of sizes and capacities, air compressors are versatile and surprisingly long-lasting; a good model could certainly last a lifetime if properly cared for. Using compressor powered pneumatic tools offers a number of benefits; pneumatically powered tools tend to be more brawny than those powered with strictly electricity, they offer greater torque and higher RPM for quick work and rapid firing. Pneumatic tools also offer an environmentally friendly alternative to toxic battery waste.

There are two types of air compressor, gas or electric, but each of these types is available with a few variations. Some compressors are small and portable, others are very large and stationary - the amount of power your compressor has generally coincides with its size. These large, stationary compressors are best suited for industrial applications and can be used by more that one person simultaneously. Compressors also vary from single stage to two stages; a two stage motor has the ability to change speeds during more constant and rigorous actions - essentially a two stage motor works harder when you need it to. Lastly, some compressors require oil lubrication while others run entirely without oil. Oil lubricated compressors tend to run more quietly; they do, however, require oil changes, operation on a flat, level surface, and may release an oil mist into the air which is highly ill-suited for applications like painting. Although many craftsmen prefer to use oil-lubed compressors because they tend to last longer and run quieter (as with any other type) they may not be practical for some applications.

Gas powered compressors are optimal on jobsites or construction zones that have not yet been outfitted with electrical power. These compressors provide the power and speed of pneumatic tools without the need for power cords or electricity. Gas compressors must, however, be used in open and well ventilated areas. Electric compressors are generally the best choice for home and shop use. They tend to run more quietly and don't stink up the joint, if you will, with a gas motor.

Keeping your air compressor well maintained will truly determine how long your compressor will keep on kicking. There are a few simple steps to ensuring your compressor remains in optimal condition, and you certainly won't regret the time you spend caring for your tool. The compression that occurs in the air tanks of your compressor causes moisture to accumulate inside those tanks. That moisture, in turn, runs the risk of rusting out the tanks, and potentially destroying a paint mixture (if used with a paint sprayer). On the bottom of the compressor there is a moisture release valve; it is crucial to release this valve with every use, this should prevent rust or other water damage. An in-line filter can also be be purchased for any compressor to eliminate water mist in your air lines.

Its important to inspect your compressors; periodically check and tighten any fasteners, make sure your air filters are running clean and replace them when necessary, check your hoses often for breaks, cracks, or leaks and be prepared to replace them when needed as well. Its also important to be certain that the compressors safety valve is functional. The safety valve (either automatically or manually) releases air should the compressor become over-pressurized; a vital feature, so be sure its operational or have it repaired. If you have an oil-lubed compressor, check the oil levels before each use to make sure the tool is properly lubricated. Change the oil as the manufacturer recommends. As far as cleanliness is concerned, its always beneficial to keep all your tools clean as a whistle and especially important to keep the compressor's intake vents clean and clear. If you have a gas compressor you may also consider periodically cleaning the fuel tank for good measure.

A good compressor is a superior tool, and can truly take the edge off a jobsite or home-repair project. With unmatched speed and power a compressor and their partnering pneumatic tools will change the way you build. Love your compressor, purchase the model that best suits you, keep it well-maintained, and your compressor will work as hard as you do.

Setting Up A Pneumatic System For Your Garage Or Shop

Air tools are great work savers. However, for years most people thought you had to be either rich or a large full time auto repair shop to have an Pneumatic air system.

Fortunately for today's consumer, setting up an air system is fairly inexpensive and quick.

You can get started with just the basics and gradually add tools as you need them.

What You Need: The Basics

An air compressor

Hose

Regultor & Guages

Air Tools

Next Step: Choosing The Right Compressor

When choosing the compressor, you should have in mind the type of tools you'll be using. There should be a tag on the compressor that rates the "Air Delivery". It may say something like "5.9 AVG. SCFM @ 90 psi."

Now, on your air tool there is another number, this number is called the "Air Requirement" number. This number will look like "5.5 AVG. SCFM @ 90 psi."

All you have to do is make sure the "Air Delivery" number on the compressor is larger than the "Air Requirement" number on the tool or tools that you'll be using.

Next Step: Choosing the Right Fittings

There are two types of fitting for air tools. Industrial and Automotive. These two types of fittings CAN NOT be interchanged. You'll have to decide before buying components which style you want.

You'll also have to determine which size of fitting you want. Fittings are measured by the inside diameter (commonly called the ID). I personally prefer the 3/8ths over the 1/4 inch, but either will work well for the occasional user.

Be sure to choose the same NPT number on the air inlet of your tool as the fitting NPT number.

Next Step: Choosing the Hose System

You could just get by with air hoses laying all over the place, but that is dangerous and it makes your Garage or Shop look cluttered.

You should invest in either a reel storage system or coil hose if you you won't be far from the compressor.

Next Step: The Tools

As stated above. Decide early on which tools you'll be using and make sure your compressors "Air Delivery" rating is higher than the Pneumatic tools "Air Requirement" rating. One of the best practices to use it to determine what the largest tool that you will ever use is. For most of us that may be a Air Impact Wrench.

Understand The Differences Between Hand Tools, Hydraulic And Pneumatic Seals

To understand the differences between hand tools, hydraulic and pneumatic seals, one must understand exactly what these tools. The definition is simply a tool used in the zone to be held in bundles of boxes or other packages. They are usually like this, because the data must be transported attached to a different location.

The straps prevent rotation and damage to property or damage to reputation, everyone in the heap.

Here the choice between a hand tool, hydraulic or pneumatic sealing the game to know the difference between the three can help an individual to decide what is best for their particular needs.

A manual crimp tool can be used both in society and family. Guide that is exactly how it sounds.

The individual determines the length of the ribbon and cut his hand. Although some machines to cut a predetermined length and move yourself, the manual crimping tool may be something to the operator. This means that the trend towards the user. However, it is very light and can use the data horizontally and vertically. However, hand tools for good jobs in small quantities. It can be quite tedious.

Regarding the banding, there are various sizes, which means that there are different size machines. What do you intend to take with the type of group should be established. When you run a great band surgery, you may want something that is more on the side of the car to invest.

Tools Hydraulic seals are those intended for larger jobs. They contain air pumps that enable them to operate. Some manual work, may require the operator or can be fully automated. These are large machines that can operate continuously required band. Every time a company has large contracts that may not be able to hand bend zone, the hydraulic seal tool can help us take a case.

These machines usually accept different kinds of films. All you need is that the size and weight of the item that is committed to change. This is a very strong grip, so it was outside elements.

Air seals are not commonly used tools in the domestic environment. It is mainly used in an environment. These are the films of packages that are perfect dish. It weighs a lot and is a compressed air engine, which many times when these packages can be stored unite. You can even adjust the margins and the band are good things, such as wooden slats. It can be horizontal or vertical band and can literally be in any environment, the property will require a lot of money.

Then of course there is the fact that there are different types of seals pneumatic tools. Some area of steel to be used with different widths and thicknesses. What is the size you need pneumatic seals movies committed to buy. However, what is your movie, this kind of group should be established.

The differences between different types of seals and tools are obvious, and the types of products to be shipped small to determine the type of joints is a necessary tool. The size and weight of the article will also determine the type of film is necessary. This applies to product safety and people who need work around them.

How Pneumatic Tools Work

Pneumatic tool use is quickly becoming the most affordable and efficient way to work on projects around the home and in the shop. When it is time to work on your home improvement projects there are many reasons to choose hand held pneumatic tools. UK suppliers are available to provide you with all the necessary products and accessories to make your home projects go as smoothly as possible.

Pneumatic means "contains air" and that is exactly what is powering your equipment. These are designed to make your work easier and eliminate the hard work that is required to drive nails, turn screws and a variety of other tasks. They are affordable and provide the user with professional results in all of their projects.

The air compressor you will use is the source of power for your pneumatic tools. It is also the biggest investment that you will make in your equipment box. There is a wide variety of air compressors available to power your hand held pneumatic products. UK suppliers of these compressors will give you a choice of size, air pressure and air flow capacities on their selection of compressors. It is important that you choose the right one to accommodate your pneumatic equipment.

There are a number of attachments you can include with your collection of pneumatic tools. These types will run much cooler than their electrical counterparts because it is air that is the source of energy. Some attachments to consider include the blow gun for such jobs as blowing away dust and dirt, a nail gun for ease in driving nails, a spray paint gun, air stapler, air sander, and caulking gun. All of these can be powered with the use of air and an air compressor.

Pneumatic tools will last for many years if they are properly maintained as there are few moving parts. UK suppliers will tell you that this is the reason why they are almost indestructible. Keep them well lubricated and properly cleaned and you will have and enjoy them for many years.

It is also important to note that you must use safety precautions when using your pneumatic product. Wear the proper safety equipment to keep you safe during operation. Read the instructions that come with them carefully to ensure that you are taking the proper safety precautions. For some of these, there is a great deal of air pressure and a serious injury could occur if you are not following proper safety guidelines.

When choosing the pneumatic tools you require, make sure that you are considering your needs for the project as well as the running time for the compressor. There are experts available that will be able to help you determine what your needs are and which will fit your requirements best.

The Pneumatic Air Tool Option

Now that you have decided to make the new shed in the backyard your workshop shed it is time to think about those new tools. You have studied both the battery powered tools and electric corded tools and now it is time to have a look at pneumatic tools as well. Let's take a closer look at the pneumatic air powered tool option in your shed planning.

Being air powered tools we know from the beginning that a generating source to compress air will be needed. Air tools tend to be light weight and have a housing constructed of aluminum and steel. They have fewer moving parts which constitutes less parts wear and breakage and results in fewer repair costs.

Another reason for the light weight of these types of tools is the lack of any electric components and because of this lack of electric components they also cost less. Being air driven pneumatic tools have more power and are safer to use than their electric counterparts. The overall life expectancy is greater than both the battery powered tools or the electric corded tools and so the result is lower replacement costs.

As stated above a source of compressed air to run the tools with is needed in the form of an air compressor. This will have to be an electric powered generator as battery or pneumatic is not really feasible. To work for extended periods the air compressor should have a storage tank that will have a capacity of 4 to 5 gallons. A smaller tank than 4 to 5 gallons will quickly expend the quantity of air it contains and you will find yourself waiting for it to cycle.

Cycling simply means the machine has to build up enough air to run the tool. It is recommended that the compressor be able to produce at least 135 psi of pressure and have a pressure gauge that will measure up to at least 135 psi (pound per square inch). There will be times when more than one tool may be needed at the same time so it is very beneficial to have multiples outlets on the machine.

The first pneumatic tool you will probably want to buy will be an air nail gun. When a project requires lots of nails an air nailer will make short work of the task. There are many types of air tools that can be purchased some of those are an impact wrench, air ratchet, pneumatic grinder, sanders, spray guns and screw drivers to name a few.

So now the choice has to be made. There are three types of like tools, powered three different ways. I guess the only thing to do is weigh the pros and cons and use your own best judgment on what works best for you. Good Luck!

The Benefits of Pneumatic

Elevators for homes and small commercial buildings come in four different types: hydraulic, winding drum, machine traction drive, and pneumatic lift. The latter of these four is known for giving a panoramic view when installed and require less installation time and costs than other types.

If you're considering adding a residential elevator to your home, pneumatic lifts are one of the more economical options, especially as no machine room, pit, or hoist way has to be carved out of your home. Using a clear tube with a car inside, the system for a pneumatic elevator can be placed anywhere, as long as the ground is level.

The compact nature of pneumatic residential elevators makes them popular for those looking for a convenient way to get from floor to floor in their home or small commercial building. The cab inside a pneumatic lift can move up to 30 feet per minute and up to 35 feet at a time. Additionally, no lubrication is needed to move the cab.

Instead, air pressure regulated by a valve moves the elevator between floors. If you're looking for more ways to go green and reduce your carbon footprint, these residential elevators involve minimal energy consumption, with only a slight amount used to move the cab up via turbines.

How does one of these residential elevators work? To lift the cab inside, a piston depressurizes the area inside the tube and the lowered air pressure above and increased atmospheric pressure below the cab causes it to lift. When the valve above controls the pneumatic pressure, the cab descends.

As far as stopping on each floor, the tube has locking devices on the interior to stop the cab at upper and lower limits. Residential elevators need emergency features, and pneumatic lifts are all equipped with a braking system in case the atmospheric pressure inside the tube returns to normal.

If you're considering a pneumatic design for your home, such residential elevators are capable of lifting 450 pounds. While the cabs for most aren't wide enough for handicapped access, they're sufficient enough to move one to two people standing between floors of a home or small commercial building no more than three stories tall.

Consider the Pneumatic Elevator

The pneumatic elevator lets your home sport that futuristic look of transparent tubes transporting people in science fiction films. With this kind of equipment, you and your family can now enjoy the reality of being transported to the different floors of your residential buildings in these high-tech tubes that do not need cables, pulleys or pistons.

There would be no visible material supporting the cab of this vacuum elevator because it is actually air that is performing this function. Plastic and aluminum are used because minimizing the weight is vital in the pneumatic elevator where the difference in air pressure between the top and bottom of the cab is responsible for lifting it or bringing it down.

The Principle Behind This Elevator

The basic principle in the design of the pneumatic elevator is that a long transparent tube contains the cylindrical elevator car with a diameter that is slightly smaller than that of the bigger tube. The floor and ceiling of the elevator car are airtight and a vacuum pump is allowed to suck the air out of the top of the long tube. This will cause a vacuum to form at the top of the tube.

The air pressure underneath the floor of the car will then slowly push it up as the difference in air pressure between the top and bottom increases. To lower the car, the vacuum pump is turned off. As air returns to the vacuum space, the difference in the air pressure decreases and the elevator gradually goes down. With this system, it can be seen that there is no chance for the car to drop abruptly.

Why Should You Choose This Kind of Elevator?

Some of the benefits offered by this particular design for home elevators include ease of maintenance, operation and installation when compared to the usual residential elevators. There is no need to dig a pit and hoist way so that these are appropriate for homes that have already been constructed.

Another vital advantage of this personal elevator gizmag that may not be surpassed by other designs is the safety that it provides. As can be seen from the above discussion on how it works, it is impossible for the elevator car to go into free fall. In addition, if a power failure occurs, the car cannot drop suddenly but only slowly as the air gradually returns to the vacuum space.

Another essential advantage of the pneumatic elevator is, of course, its futuristic appearance. Friends will surely be amazed by its looks and this will also increase the market price of your home. This market value will be further enhanced when buyers learn about its inherent safety features.

Another essential benefit is that electric consumption is much less than for conventional elevators because it does not require electric power to bring down the elevator and it also requires less power to go up. Maintenance is also less costly because lubrication is not required and there are no complicated parts.

How Does A Pneumatic Thermostat Work?

Function

A pneumatic thermostat is a device that is hooked up to a heating system in a home or business setting according to the Dr. Fix It website. The thermostat can be set to react to a specific temperature, either causing an air conditioning system to turn on or a heating system to turn on.

The thermostat does this because it is connected to a series of tubes, and can tell the temperature of the environment based on how much pressure is contained in them.

Air Conditioning

Using an attached dial, a pneumatic thermostat can be set to keep a room as close to a specified temperature as possible. When a room is getting too hot, the air pressure in the tubes connected to the thermostat will be greater.

This will cause the air conditioning system to kick on, cooling the room back down to the specified temperature. At this point, the air pressure in the tubes will return to normal and the air conditioner will automatically kick off.

Heating

In the winter months, a pneumatic thermostat can control a home or businesses heating system in much the same way it would control an air conditioner in the summer months.

After specifying a temperature, the pneumatic thermostat will sense when a room gets too cold as the air pressure in the connected tubes will dissipate. It will then turn on the heating system to return the room as close to the specified original temperature as possible.

Older thermostats were controlled by a device called a thermometer coil. Thermometer coils are made out of bimetallic strips--two strips of metal attached together. When the temperature goes up, metals expand but different metals expand at different rates. That makes the coil expand as it heats up and contract when it cools. When it contracts enough, the coil bumps into a switch which turns on the heater. As it expands, it moves away from the switch, turning off the heating again.

Bimetallic thermostats are large, bulky and not very accurate, and have been largely replaced by digital thermostats. Digital thermostats use thermistors, special resistors which are sensitive to temperature changes.

Most resistors resist the flow of electricity at a constant rate, but thermistors change as it gets hotter or cooler, slowing or speeding the flow of any electric current fed through it. In a digital pneumatic thermostat, a current flows through the thermistor to a meter, which calculates the temperature based on how quickly the resistor lets the current flow.

Ways to Choose a Pneumatic Nailer

Selecting a pneumatic nailer can often feel like an overwhelming task, because there are numerous features and options to choose from. Visiting home improvement stores and shopping online is less daunting when you are supplied with informative advice.

The following steps will guide you in choosing a pneumatic nailer for your needs based on project type, function, trigger mechanism, nail depth and size, and general maintenance.

Determine your project. Based on the job type, choose whether a coil nail gun or a stick nail gun will be appropriate. A coil pneumatic nail gun can can hold more nails and is very maneuverable, but it is more costly. A stick pneumatic nail gun is best for smaller jobs and is much less expensive.

Decide the function of your nailer. Flooring pneumatic nailers are manufactured to nail down wood flooring. Finish pneumatic nailers are generally used to nail furniture items. Roofing pneumatic nailers are designed to nail down shingles. Framing pneumatic nailers are used to push long nails into thick objects. Some nailers can do more than one function.

Choose your preferred trigger mechanism. A squeeze and release mechanism distributes one nail at a time and is usually found on high end professional nailers. A bump-fire mechanism allows you to squeeze the trigger and then bump the area where you desire the nail to go. A one-for-one trigger mechanism will drive one nail each time the trigger is squeezed.

Look for a pneumatic nailer that allows for easy nail depth adjustment. This will help control how far down your nails will be driven.

Many projects require a variety of nail sizes. Select a pneumatic nailer that easily adjusts for multiple nail sizes to avoid reloading delays.

Research the maintenance required for the pneumatic nailer. Check to see if it needs to be oiled and how often. If the nailer needs to be serviced, note whether special tools are needed or if it can be repaired at the job site.

Reasons for Using a Portable Air Compressor with Pneumatic Tools

First, pneumatic things get done around the house. I noticed this when were first married. It was about 10:00 pm at night, and I noticed that something needed doing in the bathroom. I made a comment that we should do that soon, and he said, "how about right now." I was very impressed! My Dad takes forever to get things done. And,no, it was not just because we were newly weds, things still get done quickly and competently.

The second great thing about marrying a DIY kind of guy, is that you always know what to get him for birthdays and Christmas, a power tool. Originally, it was basic, corded power tools, then it was cordless tools that he preferred. Then, for an outdoor project (building a fence), he got a portable air compressor and a nail gun (we call it a ka-chinker) and it was great! From then on, new tools had to be air tools.

Now, as I learned about air tools, I discovered many advantages to using one with a portable air compressor.

1.They are a good value. Though you have to put out some money for the portable air compressor, often air tools (or pneumatic tools) are less expensive than cordless or corded power tools. Also, pneumatic tools often last longer because they do not have a small motor that can burn out. Instead, they are drawing their power from the larger motor of the air compressor.

2.Mentioning above that air tools do not have their own motors, brings up another advantage. No motor means they weigh less. Though tools are often used by big, strong men, more can get done more comfortably if the tool is smaller and lighter, it makes the tool easier to handle, allowing for better efficiency.

3.Since pneumatic tools draws on the larger motor of the portable air compressor, they can deliver more torque and higher revolutions per minute than their electric counterparts. This allows your do-it-yourselfer to work more quickly and effectively.

4.It is really easy to change from one tool to another, making your portable air compressor very versatile. Besides using it with tools, it is great for inflating numerous items around your home. So, the use of the air compressor for other things is an advantage in itself.

5.You don't have to worry about an electric cord getting in the way, or if it is long enough to reach the project. This also means that you avoid the hassle of working with a long extension cord.

There are many pneumatic tools available. This includes drills, hammers, cutting tools, grinders, impact wrenches and hatchets, sanders and polishers, spray guns, grease and cleaning guns, staplers and nailers and more. Making the change from electric or cordless tools to air tools is simple, and you do not have to do it all at once.

Start with purchasing a portable air compressor and one pneumatic tool that you need or use often. Then, as you need new tools or want to replace older ones, just purchase the new tool in pneumatic form. I don't think that it will take long before you agree that air tools with a portable air compressor is the way to go!

Pneumatics Gets Lumber Mills Rolling

In the lumber industry, productivity demands are staggering; output is often measured in lugs per minute, a unit that describes how quickly a machine can process logs and boards. OEMs and timber-processing end users also need machines that can withstand harsh mill problems where temperatures fluctuate, dust damages equipment, and vibrations stress and grate machinery.

Traditionally, heavy-duty steel pneumatic cylinders were the only long-lasting hardware used in lumber production. However, over the past few years, pneumatic solutions combined with lighter and less expensive aluminum have improved sawmill production.

Mills resisted using aluminum because failure of aluminum pneumatic cylinders was common on equipment such as trim saws, where high speed and shock overstressed the units. Even though aluminum cylinders are less expensive than steel, the steep cost of downtime made sawmill operators question their use. “Downtime in a mill is about $1,000 an hour,” says lumber industry consultant Bill Bowlin. “So if a trimmer stops for some reason, the whole mill stops because all the boards have to pass through the trimmer to get out of the mill.”

Now, a new combination of pneumatics, aluminum, and ideal cushioning increases cylinder longevity and performance. The latter is a solution developed by Bosch Rexroth Corp., Lexington, Ky., that gently decelerates the pneumatic piston as it reaches end of stroke inside the cylinder to eliminate bounce and end-cap slamming, two main culprits of cylinder wear.

It is particularly useful for eliminating excess piston movement and bounce on quickly cycling, highly kinetic sawmills, especially in trim saws where pneumatic cylinders constantly drive blades up and down. Piston velocity — at its maximum speed throughout the stroke sequence — is exactly zero when it reaches the end cap. Vibration and noise are reduced and cycle time is improved, boosting machine speed as much as 30%. Cylinders with ideal cushioning are also lighter to further improve acceleration and cycle times.

Advanced Sawmill Machinery Equipment Inc. (ASM), Holt, Fla., worked with Bosch Rexroth to incorporate aluminum cylinders with ideal cushioning in its Series 140 Trimmer. The machine builder wanted to offer faster cycle rates and more durability.

ASM president David Seffens says the cylinders make their high-speed trimmer competitive and play a big role in opening up the 140 to 200 lugs-per-minute market for ASM. Seffens also notes that all the saw ladder surfaces on the Series 140 Trimmers are machined, keyed, and require no alignment by the customer. With the aluminum cylinders, each machine is customized for speed at the request of the end user.
