<p>It may be dependent on the rivet gun used, but I can certainly tell when I've over-driven rivets with my Zenith supplied rivet gun. If I use more than a certain pressure, the Zenith rivet head is clearly pancaked. It's very obvious. I finally settled on 45 psi for both A4 and A5 rivets, though I may have gone a tad higher on the A5's at times. </p>

<p>Can anybody tell the difference between a rivet set with air gun or a hand rivet squeezer? Can’t see how psi make a difference, the rivet pops a the correct mechanical load, not speed. </p>

<p>Reviving an old thread. Is it possible to under-drive or over-drive a rivet? I inadvertently left my compressor set at a higher pressure when filling the tires on my motorhome. I then did a bunch of riveting. They look the same as the others but it sparked the question of over-driven rivets.</p>

My wife and I have noticed that using more than 45 psi for A4 pulls fast enough to dimple the side skins. Slowing it down (40psi when triggered) leaves a nicer finish and is much more controllable. FWIW.

<p>I recently was riveting powder coated tip fences to the HT. I had pre-drilled the rivet holes prior to the powder coat and had to clean them out with the drill bit to remove the powder coating in the hole so the rivet would fit.

When I used my pneumatic riveter with the A4 rivets, I noticed the powder coat had delaminated in a circle around some of the rivets! Apparently, the pneumatic riveter pulls the rivet so fast the air pushed out from under the rivet head and tracked underneath the powder coat, lifting it off the metal!!!</p>
<p>Next time, I'm going to use a hand riveter if I'm in a similar situation with a powder coated piece!</p>

<p>Hi All...</p>
<p>Thanks Very Much to everyone who took the time to answer my question.</p>
<p>It's almost time to be able to put the propane heater, and insulated overalls away and make some serious advances with the kit.</p>
<p>Best of luck to everyone with your builds.</p>

The way I understand it, the rivet stem is broken by the pull tension, nothing to do with the the PSI of the gun as long as it meets the minimum pull to 'pop' the rivet. Higher PSI would pull faster, but rivet should set the same. I've run mine on just the tank pressure, starting at the max of 120 and running it down to the minimum pressure that would set the rivet and I could not tell the difference in the set.

I use a pressure around 90 PSI. I push the riveter down onto the rivet as I pull it. Have had no problems whatsoever.<br />

<p>Hi Robert,</p>
<p></p>
<p>I use the 85-90 psi setting at the compressor and then fine tune using the 1/4 turn valve at the rivet gun. Any method you use to eliminate the bounce should work fine. These multi-grip length rivets are pretty easy to use.</p>
