Installing a door knob without a pre-drilled hole involves creating your own hole. This process is called 'backbore drilling'. It's a bit more involved than a standard installation, but it's definitely doable. Here's what you'll need:

  • Door knob set
  • Drill
  • Drill bit (slightly smaller than the diameter of the door knob's spindle)
  • Pencil
  • Tape measure
  • Hammer
  • Chisel
  • Screwdriver
  • Sandpaper (optional)

Measuring and Marking

Before you start drilling, you need to measure and mark where you want the door knob to go. Here's how:

  1. Measure 36 inches from the floor to the center of the door. This is the standard height for a doorknob.
  2. Mark this point on the door with a pencil.
  3. Now, measure 4 inches from the edge of the door and mark this point as well. This is where the latch will go.
  4. Connect your two marks with a straight line. This is where you'll drill your hole.

Drilling the Hole

Now that you've marked your spot, it's time to drill. Here's how to do it safely:

  1. Clamp the door securely to a workbench or have someone hold it steady.
  2. Put on safety glasses to protect your eyes from debris.
  3. Start drilling with a drill bit slightly smaller than the diameter of the door knob's spindle.
  4. Drill slowly and steadily, using a light touch. You don't want to split the door.
  5. Once you've drilled through the door, switch to a drill bit that matches the diameter of the door knob's spindle. Drill from the other side of the door to create a smooth, clean hole.

Installing the Door Knob

Now that you've drilled your hole, it's time to install the door knob. Here's how:

  1. Insert the latch into the hole you've drilled. The latch should fit snugly.
  2. Insert the spindle through the hole from the other side. The spindle should fit through the latch and extend out the other side of the door.
  3. Attach the doorknob to the spindle. Tighten the set screw to secure it in place.
  4. Attach the strike plate to the door frame. This is the part that the latch will catch onto when you close the door.
  5. Test your door knob to make sure it works properly.
