PSI pressures

[JurgenRoeland]

I found on a website from another builder where a link was made referring to a "operating pressure chart" for compressor settings for the rivet gun to Dan Checkoway's website. The link was broken and I didn't find the chart on other locations using google.
Does somebody else still have this chart and could you please forward it to me.

Thanks in advance,

Here is a table that I have been using:

The pressure needed to drive a rivet also depends on the rivet gun - some need more pressure than others. And, it depends on how stiff the underlying structure is. The rivet gun has to deflect the structure to push the rivet against the bucking bar. You need higher air pressure if the underlying structure is stiff than you do if it is weak.

Be prepared to adjust the pressure as required to get acceptable results.

Thanks Bruce that helps.

I have a 3X. Understand that it is only a reference. but it is good as a common starting point

The right answer

Be prepared to adjust the pressure as required to get acceptable results.

This is the only right answer.

I got Dan's CD when Dan had it available.

"Suggested Operating Pressures
As I mentioned, I use different operating air pressures at the rivet gun for various different sizes of rivets and material. I put this table of information together based on my experience. Keep in mind that I use an Avery 3X rivet gun, and that your results may vary (some builders opt for a 2X gun, which may behave very differently). Also, you can vary the duration of driving the rivet to compensate for pressure in many cases. For example, instead of cranking the psi up, you can drive the rivet for a longer period of time. Anyway, here are the "baseline" settings I use for reference:
AN426 Rivets:

Rivet Type Air Pressure Duration
AN426AD3-3 to 3-4 34 psi 1 second
AN426AD3-4.5 to 3-5 37 psi 1 ? seconds
AN426AD3-6 plus 40 psi 1 ? seconds
AN426AD4-4 to 4-5 45 psi 1 second
AN426AD4-6 to 4-9 50 psi 1 ? to 2 seconds

AN470 Rivets:

Rivet Type Air Pressure Duration
AN470AD4-4 to 4-5 60 psi 1 second
AN470AD4-6 to 4-7 60 psi 1 ? seconds
AN470AD4-8 to 4-9 75 psi 1 ? seconds
AN470AD4-9 plus 80 psi 1 ? to 2 seconds "
