So my new shoebox is a bigger hit than I expected with the local players. I have had people calling me wanting to come by and fill tanks. I guess I'm antisocial, so I ordered a scuba tank to be able to offer fills at the game.
I'm not super comfortable filling a 3kpsi tank with a compressor that will be perfectly happy to fill to 4.5k. Yes, I can shut it off early, but that is a fairly unreliable control.
If I wanted to CONVERT my shoebox to 3k psi, including a new burst disk so that it isn't a dual-pressure setup, and is safe, what would be the recommended way to do that? Move the switch? Adjust the vertical arm that hits the switch? New Spring?
If you (AGD) are looking for a 3k field tester, I'm interested.
