Overbore, salvage or scrap?

[MikeKParticipant @mikek40713]

I was recently making some toolholders for my QCTP. It's a Norman patent style, with one side slit for a clamping screw. I got one bored and another halfway trepanned before I realized they were oversize about 60 thou (1.5mm). Actually, they're about 30 thou over, but they would be 60 thou if I finished the bores.

Because of the clamping scheme I assumed putting a sleeve in the bore wouldn't hold up. Would you salvage these, and how? A completed (but not prettied up) holder is on the right.

I would bore out a bit more oversize to the current depth and loctite a sleeve in place, clamping action shouldn't cause a problem.
