I have an old shelf with doors supported on piano (klavir) hinges, which are rusty and crooked. Most of the screws on the hinge are barely holding on, so for now I am ruling out the option to replace or repair the hinge.
I already have a hinge hole cutter, which was last used some years ago with reasonable success. It looks to me that plugging a pair of "normal" (Euro) hinges would be great if possible.
My question: is it possible, and if so what should I be watchful for?
