Nail Guns Types

They rarely meet expectations in my experience - except for a limited number of type and length of nail in a limited number of substrates.

My cordless AEG nail guns are basically constructed like a standard hand operated nail or staple gun but operated by an electric motor - the nail is driven by the release of a spring that is compressed by a motor.
This basic design is shared by all the (affordable) cordless types I have seen. There are other types of cordless nail guns that are fit for purpose but they are expensive to buy and operate and consequently mostly bought only by serious professionals doing heavy duty work.

My AEG nail guns have a depth adjustment that is supposed to increase the power of the spring for deeper nail driving or longer nails but in practice the adjustment makes little or no difference...

I have an excellent AEG staple gun. Although the AEG name still exists the nails and staples have been discontinued and the aftermarket that usually delights in producing such things haven't been interested because the nail design only fitted a limited number of machines.

In all other cases in my experience those manufacturers of nail and staple guns (that still exist) continue to produce ammunition for them and aftermarket specialist suppliers will have adequate stocks, the main problem being their information is often incomplete or out of date.
In lots of cases the required staples will have been bought in by the machine manufacturer but given a none-generic type or part number which the aftermarket supplier won't recognise.

If you don't have the generic staple type or part number then careful measuring is required to match drawings provided by specialist aftermarket suppliers of which there are a few in the UK and I expect every country will have a number.
In addition most builder's merchants or good ironmonger's will stock a supply of the most popular types.

Be very careful. Sounds like a jammed unit. bent hammer or metal fragments in the mechanism. Inspect unit closely and oil. Make sure it is off no charged mechanism or power before you start.

I've repaired many nail guns and I can tell you the Stanley Bostitch N60FN uses 15 guage nails from 1 1/4" to 2 1/2" long in the FN1500 series of Bostitch nails. Nowhere does SB or any of their aftermarket dealers list what the angle of the nails is. I do know most of the SB nail guns that come through for repairs are because of damage to them from using other than SB series nails.

The nails for these guns are no longer produced by Spotnails. I am a Spotnails dealer and you can have them made by special order but the cost is not worth it. Buy a modern gun that uses something more common like the Paslode/Senco style 34 degree clipped head nails or a coil nailer. The MNS5 was a good tool but used an odd nail (I believe it is 15-17 degree without looking it up) and the tool has long been obsolete. It's too bad as I still have some parts and guns.

Stanley Bostitch doesn't make kits to rebuild their nail guns, you have to order each o-ring, seal, etc. seperately. The N16 was a good gun however there are very few parts available for them. You can go to www.bostitch.com to see what's available through them. You can also get part numbers for what you need for your guns and research any available parts on the web.

A nail gun works on compressed air.
When you hook the air hose to the gun it fills a cylinder with air pressure.
When you pull the trigger. the cylinder pressure is released onto a firing pin that shoots the nail.
The air pressure line is also connected to the trigger and therefore the trigger has to be sealed.

When ever using a nail gun, you add a bit of gun oil in the back of the gun (not 3-in-1motor oil, it has to be non-detergent gun oil)

If you haven't used the gun in a while, it is best to oil up the gun and let the oil run down into the gun.
If you use anything but gun oil, the seals will give out.

Your trigger seal has given out. It is probably an 'O' ring. You can access it by taking it apart. Look for the O ring.
Bostich makes re-build kits for the different guns that you can buy on-line.
Back when I was in construction, there were several nail gun shops that sold and serviced nail guns, and sold nails to the contractors. I don't know if that business model is still active or if you have to send the guns to Bostich service center.

there should be a button on the bottom rear of the gun, when you press it, it should release a bar that you pull back. the nails go in the dirction you nail them. sometimes the clips are too big for the guns and you have to break about an inch off of them

I think you'll have to look at your specs on your nail guns and see what the demand is . Whether measured in cfpm or psi, your compressor will tell you the max output of each of those. Then you divide the maximum sustained output of the compressor,, lets say it is 60 psi. Let's say the guns require 10 psi, 60 divided by 10 is 6 = 6 nail guns. This is completely hypothetical as I have no idea what your nail guns require, only you know what kind of guns you have.If you need to run more guns than the compressor can push air for, you'll have to invest in another compressor, maybe even one larger to handle the guns running wide open consistent nailing. Nothing a drywaller hates more is than for all the cursed clip nails not being drove in all the way, lol, and that's what will happen with insufficient air supply.

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.
