Acoustic Guitar Construction

As you can probably see in the picture, I made a small boo boo in sanding the edge og the hole (I'm so inept). I can just leave it and hope it doesn't show much or if one of you guys out there has any ideas as to how to correct it I'm listening.
Thanks

Can you get more of a close-up?

From what I can see on my phone here, it looks like you sanded one edge a little bigger?
If so, just make the rest of the hole bigger. No big deal. Don't try to come up with a complicated solution like adding wood back to the hole. A bigger hole won't hurt the sound to any appreciable degree.
If I'm wrong about the problem, disregard!

Tony, you're right about the problem. That one area is sanded a little too much. Making the rest of the hole bigger sounds like a good idea, but how?? Can't do it by hand. I'd have it looking like an octagon or something.
Thanks

You can cut a 1" ring off of some pvc that is a little smaller diameter than what you have, glue some sandpaper to it, and use it to enlarge the hole. Then another strip of sandpaper if you want it a little larger.


Edit: to be clear, I meant use a piece of 3" or so pvc, cut a 1 or 2" piece of it, and glue sandpaper to the outside of the ring.

I'd just use a piece of 3" PVC wrapped with sand paper and true it up until it is pleasing to the eye. Changing the size of the hole make zero difference. It has to look good!

Steady even motions all the way around, maybe slightly lighten the pressure on the area that's already thin...
