I decided to hand pump my Sentry just to see if still could at 69 years old but first I had to get it to stop leaking. I'm up to 2200 psi but I'm letting the pump cool down right now. The last time I used it to pump up a rifle it didn't leak at all but has been sitting for about 3 years in the shed which temps range from 120 f down to around 20 f.

Why don't people connect HPA pumps to all the workout machines people are using in gyms? They are doing all that work with "no gain. They could be potentially making some potential energy! They could even bottle it and sell it!
someone needs to make a rowing machine pump, could be dual large pumps and probably could fill tanks too.
