The Facts About Air Compressors {awesome|amazing|Great|Special}

An air compressor is a device built to compress or consolidate air inside a tank. Air compressors work fairly similarly to the way our lungs work when we hold our breath and, perhaps, blow up a balloon. The air is pulled and compressed in the tank (like air in our lungs) increasing the air’s pressure and decreasing its volume. When using the tool, the compressed air releases through a hose in a steady, powerful stream – like from our lungs and out of our pursed lips in a bursting stream of air. In compressors, the air pressure inside the tank will continue to increase until it reaches a preset pressure limit. The tool’s pressure limit varies from high to low with the type and size of your compressor. Air compressors also feature a regulator that is set to compliment the specific tool’s and application’s required pressure.

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.

How To Build A Timber Boat From Scratch {awesome|amazing|Great|Special}

The only natural material for building boats is wood. There are various designs in the art of wooden boat building. The techniques for building wooden boats depends on the type of boat, the technique and procedure for making day sailors is different from the one used for construction of powerboats, cruising boats, or performance rows among several others.

Likewise, depending on the type of boat you want to build, you have an option of choosing from a large variety of timbers.

Since wood is known to retain moisture which encourages growth of fungal spores and eventual decay, you need to protect the timber you will use to put your boat together with coatings and quality preservatives.

Different types of trees produce varying qualities of timber. It is therefore important to understand the options before picking any type of timber for construction of your boat.

Mahogany

This type of wood is ideal for construction of a boat intended for use at sea.

You don’t have to worry too much about protecting it with preservatives, the sea water will effectively perform that task.

However, fresh water will rot it away if is not properly protected. So if you intend to sail it on fresh water, apply preservative and coating to the timber.

If you can get sea water, wash the wood in it.

Hardwoods

They take long growth time, slowly tightening their grains. They are therefore known for their strength and length.

Owing to these qualities, they are the most commonly used type of timber in wooden boat building.

Teak and Iroko

They don’t wear out easily because they contain silica. Moreover, they are not affected by rot and decay.

These characteristics entice boat makers into including them in most of their boat plans.

Softwoods

They are mainly used for construction of spars, masts, oars, rubbing stakes and planked hulls.

This is because their grain is long and straight. It is also more widely spaced since they have a faster growth than that of hardwood.

How To Build A Timber Boat: Simple Steps to Follow

One of the most important things to remember before beginning to build a timber boat is that the number of ribs determines the length of the boat.

Therefore, the more ribs your boat has, the longer it is. The less the ribs you fit to it, the shorter it will be.

To get the ribs, first steam straight spruce stock. Then bend and laminate them.

Place them in a jig and pull them so that they take the shape of the boat-making mould. Finally leave them to dry.

After they are dry, remove the ribs and put epoxy between the ribs, then wrap everything in plastic. This prevents it from sticking.

To enable the setting of the epoxy, put the ribs back in the mould and hold them tight with clamps.

Screw the ribs to the bottom-board and fit a stretcher assembly inside the boat as well as below the boat. This is done by clamping and then screwing in order to keep the ribs in place.

Remember, this is temporary since you’ll not need the stretcher after the strips are put in place.

Attach a laminated stem to every side of the boat and fit the first strip and keep fitting more until the hull is completely planked.

When the boat is planked, scrape and sand it until you are satisfied that the job is properly done. Then fill the screw holds and sand more.

Dry-fit a fiber-glass cloth to one side of the boat and apply epoxy from the middle towards the ends. Perform the same procedure with the other side.

Fit the end of the boats with the cloth after cutting it.

The fiberglass cloth is now stuck to the hull on your boats exterior. When dry, repeat the scraping and sanding procedure.

Then apply another two coats of epoxy, filling the fiberglass cloth weaves.

Since you are now done with your boats exterior, it’s time to do some sanding on the interior.

Fit the seats and seat risers when sufficient sanding is done. Then remove them and apply epoxy. This time you can leave out fiberglass cloth.

Apply 3 coats of spar varnish. Remember to ensure that the epoxy has cured well. Additionally, ensure that there is no dust.

Conclusion

Your boat plans have now been put into practice and you are ready to set sail. Remember, wooden boat building will take you approximately 2 months.

Keeping your boat floated on sea water is better than leaving it fresh water. If you are storing the boat on your yard, keep it above ground and cover it to prevent damage from bad weather and allow air circulation.

Whittling – Whittling Vs Wood Carving {awesome|amazing|Great|Special}

Whittling is the removal of pare shavings or the cutting of small bits from a piece of wood. It is the most basic form of wood carving but it is not actually the art of wood carving, as it is done today. Wood carving requires a number of tools, even power tools at that. So it could get complicated pretty fast. But this is not how it is when one whittles. All you need to whittle are two things: a piece of wood and a knife.

True whittling has always been very simple. Details in the wood aren’t very refined but rather pretty coarse. When you are holding a whittled object in your hand, you know it. You can plainly see each knife stroke. Using sand paper isn’t an option. This is the exact opposite of wood carving, which typically excels in details. When you’re holding a wood carving of the same object, you usually won’t see even one knife stroke. It’s very interesting. Whittling a little girl could take a week when all you’re using is a knife. Wood carving the same little girl requires more tools but it takes just a fraction of the time. She’ll also have many details that couldn’t be produced with just a knife.

Whittling requires no special tools, no special circumstance or any specific type of working environment. Just you, a piece of wood and your knife are all it takes. You can whittle anywhere inside or outside your home, in a car, at a picnic, in a park-nearly anywhere. This is not so with detailed wood carving.

There are quite a number of special tools that you’ll likely be using when you wood carve. There are detail knives and carving knives, wood rasps and wood files, wood gouges and wood chisels. And these aren’t all of them. (Ever heard of a sanding stick?) There’s a very good chance that you’ll probably have a handful of power tools as part of your wood carving tool kit. Then you’ll also need to concern yourself with how to supply electric power. It isn’t so simple.

You really do need a designated work area when you’re wood carving. You usually aren’t even holding the wood you’re working on. Many times it’d be a vise doing that for you so you’ll need a good work bench or platform. And with all those valuable tools around, you don’t want anyone fiddling with them. Besides the possibility of losing them, many of them are dangerously sharp and no one should touch them but you. And what about that special creation that you’ve been working on for so long? You surely don’t want any spectators scoping it out when you’re not around. Who knows what’ll happen? (Hey, where’d the nose go?)

The act of whittling is considered to be a contemplative, meditative process. It isn’t so much what you’re whittling but the process itself. Wood carving, on the other hand, is more of an end result process. You strive to create what you see in your mind with all the details that come with it. You’ve a product to produce and so you may not care to spare any time.

It comes down to a matter of taste and how you feel. If you have no care to rush, you want to take your time and see what happens, whittling is for you. If you’d like to see just how skilled you can be, how good you are at bringing out details, wood carving may be just what you’re looking for. Hey, try them both. You might surprise yourself.
