The tasks of assembly and installation of furniture, carpentry, upholstery and decoration, among many others, make good use of an element of subjection as ancient as essential: the nail. As useful as it is, however, the nail could never be conceived without a tool that, unlike our hand, is capable of providing the necessary force to insert it into the desired surface. The primitive man used stones until finally the hammer was imposed, another ancient key player in the family of basic hand tools. Even today, if we have to hang some ornament, build a shelf or make a square for our dog, the hammer is the perfect tool: simple, economical and completely effective.
However, if we are involved in larger projects, such as the construction of a home or the installation of wooden floors, or plan to open our own furniture repair workshop, all activities in which we must use dozens of nails per day, the Framing nail gun be a practical solution.
What is a nail gun and how does it work?
While the operating principle of all stapler nailers is the same, there is not one that is capable of adapting to all situations, since they differ in the type and size of nails they can use, the applications for which they are designed and the source of energy on which they depend. However, all are similar in appearance, so first of all, we present a typical nailer and see what the common parts of all the models are.
To operate a nailing gun, we must first load it with a strip of nails or a coil of nails lightly adhered to each other by means of a glue. This strip/coil, which is purchased commercially and comes in various forms, with different types of nails, tacks or staples, is loaded into the cartridge of the tool! At the end of the cartridge, there is a drum that houses the hammer (also called “piston”), so that a spring locates the first nail of the strip/coil in front of this hammer.
When we connect the tool to the power supply and press the trigger, that first nail is ejected violently from the drum according to the type of nailer, two mechanisms that we will see later. Once the nail has been ejected from the drum, it completely penetrates the material to be fastened. The friction created at the time of the perforation of the material causes the fusion of the adhesive containing the nail, and it is that molten glue that firmly holds the nail in position. The vacant place in the drum left by the driven nail is immediately occupied by the next nail and the process starts once again when the trigger is triggered. Most nailers incorporate a safety system by which the nail is ejected only when the shoe is pressed against the surface of the material before pressing the trigger.
