CT, Thanks for the response. I see you are building RV-12iS also. I will be using a HF riveter for the pulled rivets. Is the air pressure the same?
I realize there are a-lot of pressure scenarios, so I agree that experimenting is the way to go with different tools.Just saw Tom's reply suggesting 35 psi for a pull riveter, which surprises me, so sounds like some experimenting is in order.

The pull rivet tool definitely works best at lower pressures. Around 35 is pretty good. Makes it much less prone to a violent recoil and the resulting bounce onto the surrounding area. Voice of experience. There are a lot of pull rivets in an RV12.
The pneumatic squeezer is a totally different tool. I can’t offer any thoughts on that one.

I let the tank fill to whatever the compressor fills to.. 125 psi or whatever, but I regulate down the line pressure for the tool. (Using an actual regulator, not a needle valve restrictor). As for the HF riveter, I find it works best at much lower pressures, just enough to pop the rivet, try 30 to 35 psi. I find a slow pop is better and cleaner than a fast 90 psi pop.
The OP title should have been "line pressure"
This post from Taltruda is correct. Tank pressure has no bearing on tool performance, as long as the tank pressure stays above the set line pressure. You need a regulated line pressure for consistent tool performance.
Dave,As far as strength goes, the pull rivet is self regulating. When the mandrel breaks, that’s it.
Cheers DaveH
I've never tried 35 psi, but have had good results on thousands of pulled rivets with 40 to 45 psi. Just another data point for your experiment!
Not sure if you've seen this video that Van's posted a while ago, but you can see Scott discussing how he sets up the pneumatic puller for pop rivets here:

Hope that helps.
