I am out of town for about a week so can't check right now BUT, as I hear these reports (good) and then revisited the pictures I am going to take another look at the crank pins in the front axle. In the photo it appears that there is excess travel available on those. If those pins are not fully seated that could have them sticking out in the breeze and catching the rod just as described. It does not alter what I've described this far but it may be that the crashing could be at least partially remedied by them being seated further. In the meantime, for those who have looked at theirs, is anybody seeing the excessive end play in the connecting rod pins at the axle end, the end where I installed the .036" spacer?
