A Lean Mean Nail Gun.

Bosch reinvents and upgraded common nail gun. Bosch made an average nail gun more efficient. As shown in the diagram, the "Bosch Full Force Nailer" was smaller than the normal nail gun, but, it has a driving power of the big guns.





Nail gun that are moved by air pressure (Pneumatic Nailers) can slash the time it takes to fasten everything from window trim to roof rafters. The basic body parts of the tool haven't change since 1960's. The nail gun still use compressed air that pushes a piston that drives a rod, forcing nail deep into wood before the tool resets for the next nail. NOw, Bosch had figure out how to make a nailer 20% smaller but having a boosting power of 10% so that it can drive nails into hard woods like walnut with less pressure than other guns. Instead of reserving some of the compressed air for resting the pistons, which weakens the strike, the tool uses all of the air's energy to drive the nails. A vent exhausts the air and a second bust return the pistons. Since Bosch nailer can operate at lower pressure, it reduces wear on compressors and components while still hammering 1 to 2.5 inch long nails all day.

Design Highlights on the Nail Gun
Self-Cleaning Filter: The pressurized air leaving the tool cleans this filter, which captures debris like sawdust and dirt, preventing it from clogging the cylinder.
Fitting: A connection to an air hose allows pressurized air to flow from an electric air compressor into the nailer, where it’s moved by valves controlled by the trigger.
Bump Firing: Like most nailers, the Bosch also has a semiautomatic mode called bump firing, in which you can hold down the trigger and fire a nail just by pressing the nose to the wood. A toggle switch on the trigger changes the position of a metal lever inside so that it touches the trigger-valve pin. At that point, depressing the nose pushes the metal lever into the pin, activating the trigger.
Depth of Drive: A dial lets you adjust the distance between the nose and the board, which changes how deeply the gun drives the nail.

Step By Step
1. A spring in the magazine feeds forward sleeves of 16-gauge nails one at a time, putting one directly under the driver blade.
2. Squeezing the trigger opens the nailer’s main valve, letting in air from a compressor that sets the 33-gram aluminum piston in motion.
3. The driver blade, a 5.3-inch steel rod attached to the bottom of the piston, smacks the nail, driving it into the wood.
4. Just behind the nose is a plastic vent that exhausts all the air as the piston descends in less than 0.1 second, so it meets with almost no resistance. A second burst of compressed air pushes the driver blade and the piston back up, ready for the next strike. In conventional nailers, a reservoir captures some of the air and rechannels it to push the piston back into position.
