What makes a door installation strong 💪 #doors #carpentry #learn

Hollow corridors are weak. They have nothing inside and solid corridors are strong. But this has nothing to do with a strong install. This stud that goes from the top plate all the way to the bottom plate makes this installation strong. So if this door is not tied into the structure or this 2 by 4 isn't attached well, it makes the door installation very weak. Let's see how screws can make for a stronger door install. Frame your opening 2 and 1/4 wider than your door, make a level mark, use shims to plumb your hinge side. Shims are best installed in opposite direction so you can shim flat. If they get stacked, you'll see that this side is thick and this side is thin. And this can twist your jamb. So we'll tack up our shims at our hinge height. Now we measure down from our level lines and trim down your high side. Now you can set your door. Now we'll continue to shim the hinge, get it plumb in this direction and nail it. Now you can measure down from the top of your jamb to your level line. The two measurements should be the same or check your top reveal and make sure that it's the same. Now you'll shim your latch side to get the proper gap. Use this shim to hold your door gap while you make adjustments on your door shim. Now nail off your latch side. Depending on if you have hardwood or carpet and pad, you need to either set your door higher or cut your door. Remove your door pins, score your door and cut it down. And this keeps your edge clean. If you don't score the door or use a track saw, it can chip up your edge. Instead of nails, you can install screws. This is installed with screws and this is installed with nails. You'll see that weight on the door wants to pull the top out and compress on the bottom. So we want to be sure that we shim behind the hinges and also fasten behind the hinges. When installing handles, use a protective sleeve or be careful when you screw them in. If you're not careful when you go to screw this in, you can easily scratch the side of your handle. You want to be sure you have longer screws that can penetrate into the framing. For exterior hinges, you want to install long screws that go fully into the framing. If you install short screws that only penetrate the casing, here's a door with screws in the framing, and here's a door that does not. You can see how the deadbolt busted right through the jamb. Thanks for watching.
