The ironic thing about ill-hung doors is that the difference in material cost between a door that swings silently and clicks shut like a bank vault, and a squealing door that you have to body check to get it to shut, is exactly zero.
The door I'm currently dealing with won't even shut with a body check applied. It has several problems, but the one I need to solve first is the too-deep hinge mortise pictured.
A too-deep hinge mortise is easy to correct. Just add a shim of the correct thickness and the problem is solved. This sort of thing is why I keep a bin full of cardstock from retail packaging on hand. It tends to be excellent quality material, of various thicknesses. Here, I'm going to need about a one millimetre thick shim. A brief rummage through my cardstock bin brought forth just what I needed.
That little punch is ideal for punching the screw holes in the shim.

With the shim in place under the hinge leaf, the mortise depth is as it should be; the hinge leaf is flush with the door casing's surface.
The next thing I have to do is take half-an-inch of length off the bottom end of the door, so it no longer collides with the edge of the hallway carpet. That raises a point about fine-tuning a portable circular saw that I really ought to do a post about.
