Just started researching making air rifles. If I use PVC, I can't really exceed 150 psi, but at the same time, I need a Schrader valve regardless of whether I use PVC or steel piping, and the only ones I have available also can't exceed 150 psi. Any suggestions for what I should do? I was thinking a check valve that can exceed 150 psi with a Schrader at the end of it, that way it can pump air in fine without having to worry about the Schrader valve shooting into my lung while I'm pumping it
I'd recommend a brass coupler for air compressors. Easier to fill if you add the valve and use an air compressor. You can also add a gauge so you constantly know pressure

best idea.

This, then get one of these to go innawoods

It'll be easy to convert it to a proper air compressor coupling. You might ask why not just leave it since it's a schraeder valve hose, and that's because air compressor hardware will last hard repetitive use, schraeder valves aren't meant to be used several times a day.

Same guy here.
I made a PVC potato cannon, and used this. I used a 2 foot section of 2 inch PVC, with a solid cap on one end, threaded with a long piece like the attached picture and washer on the inside of the cap(only using one side of the nipple so the washer was held in place by the center joint) and screwed the female coupler I show above onto the outside of the cap. I threaded the hole through the cap, and screwed it together, using lock tight, and a lot of pressure to make it air tight. That was my tank. The end without the cap met a series of reducers down to an electronic sprinkler valve, and a series of reducers opposite of the valve to a 1 inch pipe as the muzzle of the launcher. I then cut the potatoes to fit tightly. Worked well for me. I used my air compressor and filled it to around 95 psi, and got 3 shots or so going 50+ yards.
