My question is, what would happen if someone were to build a dual tail o-ringed bolt with a smaller gap between the two o-rings, so that the mechanical dwell was even further reduced? I can't find the source anywhere (have been looking for days) but I remember reading a few years back how a dual tail o-ring bolt has something in the neighborhood of 20-25 MS of mechanical dwell. I know I've lowered dwell on an L6 bolted Ion to less than that with no ill results, so what if we narrowed the space between the o-rings so the mechanical dwell were, say, 15-18 MS?
But then there is a question, whether the narrowing of the gap, should be biased toward either of the oring, or centered on some specific point?
