Yes, this is probably not feasible, but if no one asks, no one answers.
I'm thinking of pressing out the stem on the L10 bolt, having an inside o-ring groove cut in the back of the bolt, and popping in an 014 o-ring, just for giggles.
Oh, and pressing the stem back in, of course.
Figure it might help with a couple of things. If properly done the o-ring should just fit loosely on the power tube, but seal it up relatively effectively. So no real sticktion issues, and no real worries about leaking. Just a little smoother, a little more efficient, maybe a little more consistent, etc.
1. Is this madness? If so, why, and if not, why not?
2. Can one of you do this?
3. How much?
Let the festivities commence . . .
