I have a door that is rubbing at the bottom corner away from the hinge. The gap between the door and the frame on the hinge edge is wider at the top of the door.
I think the culprit is the middle hinge which has its mortises cut slightly too shallow on both the frame and the door. I need to deepen them by about 1/50th of an inch on both sides.
The mortise has rounded corners, so a chisel is not a solution.
I have heard of people using forstner bits rout out hinge mortises, but it seems like a hack to me. I need to remove an even, thin layer of wood and I think using a Forstner bit would just be too ham handed and end up cutting too deep.
On the other hand, I will not be able to manipulate a full size plunge router on the frame.
What is the solution here? How can I evenly remove 1/50th of inch of wood from the two mortises?
