what I may try is drilling the hole round again, and then making a sleeve of shim stock to snug it up. What do y'll think about that?

I think I would make a new part with a keensert. The thread should be a fine thread to get more clamping power.

I assume that you can not also make a shaft with a keyway in the shaft and the aluminium part. But maybe you could make a sleeve to fit on the shaft to increase the size of the shaft where the part is clamped on. It could be keyed or silver soldered on or set screw with dimple on shaft. I am assuming the shaft is something like a 1/4 inch dia. So with a sleeve increasing the diameter to say 3/4 inch , it would be much less inclined to slip.
