One of the factors used to designate compressor power is motor horsepower. However, this isn't the best indicator. You really need to know the amount of air the compressor can deliver at a specific pressure. The rate at which a compressor can deliver a volume of air is noted in cubic feet per minute (cfm). Because atmospheric pressure plays a role in how fast air moves into the cylinder, cfm will vary with atmospheric pressure. It also varies with the temperature and humidity of the air. To set an even playing field, makers calculate standard cubic feet per minute (scfm) as cfm at sea level with 68 degrees F air at 36% relative humidity. Scfm ratings are given at a specific pressure–3.0 scfm at 90 psi, for example. If you reduce pressure, scfm goes up, and vice versa. You also may run across a rating called displacement cfm. This figure is the product of cylinder displacement and motor rpm. In comparison with scfm, it provides an index of compressor pump efficiency. The cfm and psi ratings are important because they indicate the tools that a particular compressor can drive. When choosing a compressor, make sure it can supply the amount of air and the pressure that your tools need.

I bought a used Bostitch nail gun. Model/serial # N6408406208021. What parts do I change to go from a 1 1/2 inch nail (approx. #6) to a 3 inch nail (approx. #16)? Where do I get the parts?


I do not think that the n64 will take a 3" nail. N64 will most likely fit a 2 or 2 1/2 inch. To verify the length of nail open latch door and measure the width of the slot into the barrel. Take a look at the bostitch n80 series of nailers for more power and longer nail.

Leaves about a 1/4" of nail from seating


This can happen for a number of reasons.

1) Insufficient air pressure (should be set to around 100PSI)

2) Hitting another nail or other extremely hard surface (old roofs are known for this)

3) Defect in the gun or lack of lubrication.

Since this is a reconditioned unit, I think that the gun is probably fine. Verify that the compressor has the correct pressure and that the hose is large enough in diameter to deliver sufficient air to the gun. Check the CFM (Cubic Feet per Minute) rating of the compressor/tank combo against the requirements of the gun.

Keep us posted,

Can I change the pressure on the nail gun?


Hi there .
First check if the nail gun have a adjustment screw . Depending on the brand could be in the front where the nails comes out or by the trigger. Second check the compressor by the air hose connection you should have a regulator valve with a gauge and see if you getting the right air pressure .
Hope this help

How do you safely remove jammed nail gun?


Not sure exactly what Bostitch framer model you have, but if it is powered by compressed air, as long as you remove the air hose from the nail gun, there should be no risk of the nail gun firing while you remove the jammed nail. There should be a way to access the driver area from the top of the nail gun, even via a latch or a couple screws. Remove the top part of the driver area and that should give you access to the jammed nail, which you can remove. Use long nose pliers or something similar if the nails are really stuck.

Nail gun will not shoot


Not all 120psi air supplies are the same. Here are some differences. The pressure regulator has a great deal of effect on the performance of the air tool. Regulators are sold by the volume of air (cfm)that they can handle. The more cfm the larger the pipe fittings on the regulator. A 1/4 fitting regulator will restrict the air somewhat compared to a 3/8. Another difference is weather moisture is present in the air. Moisture will temporarily help seal the orings, however too much water in gun will cut the orings. The air hose and fittings will also stifle performance. Long small diameter hose will lower pressure at the gun. This can be measured by installing a guage on a T fitting on the end of the hose and watch the pressure as you fire the gun. Larger fittings and hose ID will improve performance. Finally, your nail gun should work on both compressors. To make your nailgun work at home, (assuming that there are no air leaks) lube the headvalve parts with silicone grease. (sold at lowes in plumbing dept) For best performance, replace the orings in the head valve, examine the plastic parts where the orings contact and look for wear and tiny scratches (use magnify lense). Replace these worn parts along with orings. Replace the head gasket and make sure that the body and the head-cap are not warped. Place sheet of fine sandpaper on flat surface, with cylinder removed rub the body of the gun on paper a few times to check for warp. Do same with cap. Parts are available at www.toolpartsdirect.com. Enjoy

Nail Gun support


Yes, because there is less risk of splitting the wood grain when using a nail gun than when using a hammer, nail guns are especially useful in delicate projects such as the application of indoor trimming. A nail gun sets the nail in one motion, reducing the chance of slips and bumps that can ruin delicate woods. Most models also include a rubber safety nose to protect the wood from friction.

Nail Gun Problem


Professional-grade varieties are automatic, and fire a nail directly upon pulling the trigger. A semi-automatic nail gun is more appropriate for beginners, since it requires a two step process: pull the trigger and then tap the barrel against the wood. This safety feature protects the user from accidentally firing a nail gun and injuring himself or others.

Nail Gun cost


A good-quality starter set, including both a compressor and a small nail gun, can be bought for around 200 US dollars (USD). More sophisticated models can reach 1000 USD or more. Optional features such as a hard-shell case, safety trigger, and depth adjustment can drive the price even higher. For one-time jobs, a nail gun can also be rented at hardware stores and home repair centers.
