Damn, but I’m good.
I made a revision to my valve design. Knocked out the body a few days ago, got the stem done today.
It glides in the body like silk, yet when I suck on it it pulls the stem up, and I cannot blow air past it. No o-ring required.
I am a lathing and milling god. Anyone want to buy one? I fancy a holiday in Argentina.

Ultra-fine precision is a joy to behold and an even finer joy to create. There is one potential problem though: fouling. I once had a rifle with a bolt that was machined to a very close tolerance. A bit of something got in the gap between the bolt and the bore it rides in and made a difficult to clear jam. All ended well but it was a bother for a bit.
Can the valve be well protected from fine debris? Maybe a looser fit and a forgiving o-ring would be a better solution for a field rifle?
