What air pressure for the air gun?

[baileyuph]

Specific questions:

1. Do you set the air pressure on the air line and that serves all requirements?
   
2.  Also regarding the line pressure;  Does it depend on the gun being used?

3. Or on the size of the staple

4.  Or on the density of the wood?

Just wondering, because I reminded myself it has been a while since the
line pressue entered my mind.

Along with the staple gun subject - what kind of luck has been experienced with
installing a seal kit - = to extend the life of a gun?  Or, have you found best to just
replace the gun?

I have several guns and seems one or two may need replaced or install a repair kit.

Thanks in advance,

Doyle,
  I set our compressor to 85 lbs. We run two or three guns on three lines and it handles it fine. Air staplers seem to work best for us at this setting weather it is hardwood, 1/4" or 9/16" staples they all work well.
  As for repairing guns I don't I just replace them.

I've tried rebuilding my guns without much luck. I'm fairly mechanically inclined but when it comes to air tools I don't have the skills. I bought a repair kit for a Senco staple gun, put it all back together to find the piston chamber (plastic) was warped and to buy a new one? Obsolete. I've spent way too much time trying to repair these guns. A new Bea can be bought for under $150. Sounds like a good deal to me.

The pressure setting imprinted on the guns I've owned is way low. My compressor is set around 90lbs

Regarding:

   a.  Line pressure (about the same as you - 85 to 90)

   b.  Rebuilding the air gun - I have entertained the idea but upon inspection of the gun, I notice
        other things in addition to seals that need replaced also. 

Another point:

The line - I have used hose straight from compressor (not as convenient).
               Also, I have used the small coil lines - but it doesn't last long.

Maybe there is something I haven't tried?

BTW, I drain the air tank often because it collects moisture.

In Florida there is plenty of humidity, I drain my tank about 2 or 3 times a year. I built a box around my compressor using 3/4 industrial particle board and insolated it with Styrofoam sheets to deaden the sound.   

My favorite set up for air hose was working in the factories of NC. The galvanized supply line came down from the ceiling with a quick connect on the end. A hose carrier was fashioned to connect and swivel around the supply line in a way that would allow the hose to follow the upholsterer 360* around their workbench. They used the coil line that helped to keep it up and out of the way. The aggravating thing about the coil line is when it twists into its self. I have a swivel for the coil line but have never had a ceiling high enough to rig it up.

I use a 50' air hose. I keep it stored on a garden hose hanger. Its nice to have the extra hose when I'm working on something outside the shop, filling tires and such.

I run a line from the compressor to the work station then a coiled hose from the ceiling with a hook to hang my gun from along with the coiled hose. Works for me. Bernie likes the coiled hose loose and dragging all over :)
The other stations have coiled hoses also.

Read the max psi on all your machines. Going over the limit can be a real eye opener! Literally.

I use 90 psi on my staplers. 22 gauge 1/4", 3/8", and 5/8" staples with no problems.

90 psi on my 18 gauge brad nailer and stapler. I can see increasing the psi when using 2" staples for hard wood.

Chisel gun and air blower on 90 psi.

My tank is at 150 psi and I have an inline valve that I set at 90 and rarely change it.

I've rebuilt my BEA stapler twice with a rebuild kit I got from my upholstery supplier. It's all new O rings and such. I recently bought a new BEA and I'll probably use the rebuild kit again when needed.

Thanks for the replies:

My settings are right along with all of yours.  The issue is, the staples cut through the fabric when driven.
I can use less hand pressure on the gun (not press hard and actually try to elevate the gun - which
helps).

Frustrating to say the least.  To be thorough in this problem, I will try (again) different guns (I guess I have 3 or 4) there are several hanging there.  Today, I will try the narrow stapler gun because it is
double welt day - this will broaden the test.

The wood in the current chair (s) is extremely hard - don't think that is the problem for I have seen
this before.

Maybe all my guns are "worn to this point"?

Doyle it does sound like you're bumper might be worn allowing the driver to come out to far.

We use 90 lbs for everything except our rivet gun. We bump up to 110 #'s on that. When you are using 304 stainless rivets you need more pressure. The staple guns like 90 lbs.
