Wood – How to repair a puncture in a hollow-core wooden door
doorsrepairwood
Someone punched my wooden door. Now it has a giant dent in it.
The dent is similar to this one. Fortunately, it's a bit less severe than this. How can I "pop" the dent back out?

You can't. Wood doesn't "pop back out". The wood is actually broken.
If you just want to repair it structurally, then filling in with something like a suitable epoxy and sanding would work.
Getting it to look like the undamaged original will be impossible or very difficult at best. This is due to the grain, and no replacement piece of wood having the same matching grain pattern.
The best try would be to very carefully get the pieces of the wood back into their original positions. Then open the cracked areas again a little, carefully insert some wood glue, back to original position, and somehow clamp or hold in that position until the glue dries. Then you still have to sand the result to make it smooth, and hope the few inevitable interruptions in the grain won't be too noticeable.
Another option is to laboriously fill in the dent with spackle, layer by layer, and then carve in a matching 'grain' with a paperclip or other such tool in the topmost layer. Then repaint, and it'll look fine.
This would take time and patience (each 1/2" layer needs to dry for a while), and be an excellent learning experience for SOMEONE.
While Chris Cudmore is right about the real fix, you could work out a temporary fix as follows:
Brace the door
Get two screws per hinge that are about the same thickness as the ones shown in the picture and about 1/4 shorther than the thickness of the door.
drill a pilot hole on the inside face of the door toward the outside spaced midway between the current screw holes. (Note that these are not on the same face of the door as the hinge screws). The hole should be thinner than the screws selected and stop about halfway through the door.
force some carpenters glue or white glue in the cracks at the edge of the door that is under the hinges. (you can force it in all the cracks if you have several clamps).
clamp the door to pull the crack together.
set the screws in the pilot holes.
Rebuild the hinge holes
lightly coat dowels or other thin wooden rods (you can use chopsticks) with glue
force those rods into the screw holes for the hinges. Add slivers of wood to fill any gaps.
after the glues have dried (next day), remove the clamps and trim the dowels flush with the recessed hinge area.
Reset the hinge screws
drill new pilot holes for the hinge screws
screw the hinge screws into the new pilot holes.
Quite a bit of fuss, but the only real cost is a few decent clamps. You need screw types, not spring clamps.
Or you could ask your landlord to fix /replace the door.
