The simplest nail gun uses strings to operate. It is very helpful to learn how it works and its basic mechanism.
When loading a nail, you must glue them together but loosely in a long strip. The nail strips are fed into the barrel of the gun. Then the spring pushes the nail into the barrel. The nail is separated from the strip, and then out to the wood the time the nail comes down. After the hammer cocked back, the next nail will be in the position.
Solenoid acts as a hammer in the nail gun. At the time the trigger is pulled, the piston is attached to the sturdy blade. If the trigger is pulled, the electrical circuit brings the current to the electromagnet and piston extends downward.
There is a blade in contact with the nail. It forces the nail out of the gun. The piston hits the electrical switch which is at the bottom of the cylinder. When the switch is thrown, it reverses the current through the electromagnet. This electromagnet then puts back the piston in the position for another hit.
There is a specific nail that must be used for a specific type of nail gun. It is important therefore to learn also about the different types of nails, and know where it is used for. The common ordinary nails are used in wood that do not need finishing. This is usually used on 2x4 boards. It is also used in all remolding efforts at home and the garage.
Casing nails are required for all finer works. These nails are used for cabinets and molding works. Finishing nails can be interchanged with casing nails because they are both for finer works at home. It has a rounded nail head that can be fully sunk or not.
Common brad is one kind of nail good for small, light works. Like casing nails, it can be used for trim works. This is a lighter kind and shorter than common nails.
Box nails are like common nails with larger heads and larger shank. This is used for framing and decking. This nails offers extreme holding power.
When you are out of the budget and you think all you can afford is just a second hand gun nail. It could also be okay as long as you take into consideration some guidelines in choosing a good condition gun.
Choose the one that still works smoothly, meaning it has no hiccups and no undue recoils that may take place. If the nail gun uses spring mechanism, make sure the spring is not loose. Also make sure that all internal mechanism of the gun still works well. To be sure, you can take it to a service center.
Try using it once or twice. Be careful that the gun will not burn your hand or palm. See if there is still warranty left. If you are buying used cordless nail gun, check the life of the battery left because you might have to buy for a new battery and it might cost a lot.
