O-ring hell, jbweld instead?

Sorry I don't have actual pics, no camera with me to me at the moment.

My plug leaked when I screwed it in place on my barrel-sealer-in-progress. I dremmeled out a groove and put an o-ring on it, it kept blowing out due to bad placement ( the one on the right in the picture ), and then dremmeled out a second grove ( the one on the left ) and put a second o-ring on it, and it still leaks.

I know that my piston works, because even though it leaks very rapidly, I can turn off the air and fire it and still get the piston to actuate.

If I sand the edges of the tee and plug and JB weld them together, will it be safe up to 90 psi?

Note: This is a strong leak, and on a pretty big compressor doesn't let my gun get over 40 psi.

JB Weld will hold anything your compressor can put out, but I find it difficult to manipulate for sealing leaks.

It sealed the leak, but now my piston is ruined and there is no way to fix it. It isn't sealing completly and all the air escapes out of my trigger, with just a very faint movement of my piston. I think I'll stick to sprinkler valves =(.

sometimes you just have to have a lathe.
