As a Christian scientist, Dr. Bohlin is open to examining the theories of both young-earth and old-earth scientists to explain what we can observe today. The Grand Canyon provides an excellent venue to consider the theories of both groups on how the geological layers were formed and when this occured.
If the door is already attached, swing it open and closed to see how much inertia it has. An average hollow-core door usually weighs around 25 to 30 pounds, so if you can lift or swing the door with minimal effort, it is probably hollow-core. Solid-core doors are usually 25 to 30 pounds heavier than their hollow counterparts, so if the door has some heft to it, it's probably solid-core.
Even hollow core doors have reinforcement blocking where a handle would normally be installed. So mount your handle in from the edge of the door to the center of the handle 2+3/8 and up 36 from the floor.You should hit this reinforcement in the edge of the door.e moved into a house where the owner had installed a handle on the pantry door, which is hollow-core, where the screws go into the face of the door (a lever-type handle that doesn't actually move up and down...just serves as a pull).
