I've seen a pic on this site of a stripped jacketed round, the groove was triangular from front to back(widest at front, as it should be). And you still don't think the radial acceleration forces are significant? I don't know if that pressure bump is the primer or the jump to the lands. Are we in agreement yet that lube pressure requirements are not really that high and heavy duty greases aren't really needed, the reason for my post? How could we be in agreement, neither of us has produced any valid data or calculations yet. Several of us are interested in CB alloy requirements also, but this is Gear and R5R lube thread. It's an ANYBODY thread, for those with interest, questions, or contributions, like yourself, please continue to contribute. We don't have to all agree and reinforce each other's conceptions or very possible mis-conceptions on every point, otherwise we'll never be any the wiser. Their work just might provide us with a lube that meets their list of requirements. If they do, I'll use it.
