Christopher, nice project. And your project reminds me… One day I went to one of our valley’s auxiliary recycling places, much smaller than our regional-district dump. The place I went to is just a limited parking area with five recycle bins. Though they’re not supposed to, some people leave miscellaneous junk on the ground — children’s clothes and toys, old VHS videos, what have you. I found that someone had left an 11-gallon air tank with an outlet check valve still on it, but the compressor unit itself removed.
Looked it over, it seemed to have no cracks or rust where air might leak and it had good wheels & handle, so I brought it home. I have a compressor, but it’s stationary in my welding/grinding area. I figured if I could feed air into the little tank (and release it out as desired) that I could use it as a portable to run my tacker from.
I bought a few brass fittings for the tank, including a second check valve to contain air and allow control. The pic shows my compressor setup feeding the red portable tank. Not shown, but the little tank's outflow hooks up to pneumatic hose lines. First project I used it for was with my stapler, to re-roof one of our sheds. Also comes in very handy for pumping up vehicle or cart tires.
