Oh definitely. I was a little surprised my search for a solution here on SBO turned up precious little (I always try to scour the forum before posting - it has resolved many issues for me in the past). That leads me to believe this is a trivial problem to solve (extra rivets, doubler, banding, welding, etc.), and that I was likely overthinking it. I certainly found nothing about a mast "buckling" from any repair technique at the base, but a few stories about mast splices snapping up near the spreaders. But there was one rebuke for gluing the damn foot in, which in this era of space age adhesives, seemed like a good solution to me! Thanks, I'll definitely post some closure down the road.
