stripped pedal bracket holes

[John Formsma]

List,

Baldwin studio with all four pedal bracket screws stripped.

I've not had to do this exact repair before, so I have some questions.

Is the best repair to plug and redrill?

If so, it appears that the bottom board will need to be removed because
I don't see a way to get a drill bit perpendicular to the bottom board
since the plate is very much in the way. There's only about 5-6 inches
from the board to the plate. Maybe a right-angle drill? (which I don't
yet own so don't know the dimensions if there's enough space)

Can this be properly repaired without bottom board removal, such as
epoxy or a shoe peg? I'm feeling that this would be temporary and am
therefore hesitant to spend the time on a temporary repair.

What would you do?

Thanks,

John Formsma
