Ah yes, impact therapy. I wish I'd thought of that.
We'll save that for round 2, I guess.

Just a thought, something to check, if you didn't already look at them. Just went through a similar problem with these issues myself.

That's kind of what I was getting at in the first place with my OP:
."..that were very obviously compromised due to the previous loose fit."
This is a salvage operation for sure, so very little to lose. It seemed to me, that the damage so far was fairly minor and it cleaned up quickly with a few
judicious file strokes. At any rate, I'm not a clydesdale, so the crank is not being subjected to the worst case loading by any means. I will be tightening the bolt after every ride, until it tightens no more.
Thanks for the interest and the inputs.
