Drill it oversize and then turn a piece of brass down that is size for size or maybe .001 press fit , press it in and drill it back to the original size.I guess the better question is how to fixture it up after the bore is filled so it can be re-drilled? I was thinking epoxy and a block of aluminum to drill into with the mill. Heating it up to kill the epoxy but that can be hard work.
I'd send it back to Dumas but I don't think they would honor me buying it off eBay second-hand, only from them and they discontinuted it long ago. It's a prop for my Cox .09, about the only promising metal prop around for it so I'll have to try reworking it or scrapping it out...lol.
Aluminum is much softer than Copper Be so the drill bit might not go in straight. Having said that, I think Dumas props are cast from a different alloy and I do not know how hard the material is.I guess the better question is how to fixture it up after the bore is filled so it can be re-drilled?

You better hope the hole is straight? Cause nothing else on the prop is true enough to realign to any machine... JUNK!What can be used for a reference face to align the prop into the machine. That is the basic issue..
