Re: Replaced hollow door with old door and its binding
You probably have hinge bind which means the edge of the door is contacting the jamb before fully closed. You need to take down the door, remove the hinges so you can bevel the edge of the door away from the hinges, then rehang and check. The other possible remedy is to shim under the hinges to give clearance that way. You can only do that if you have enough clearance on the latch side. If you shim the door too far over, the latch side will bind and you'd end up planing it there.
The hinges could also be causing the door to bind along the door stop. In that case, you need to move the door away from the stop or move the stop away from the door.
Remove not the ancient landmark, which your fathers have set.
