A fun and simply project to give a kids room their own personal door knob.

Est. project time: 15min plus glue dry time

Step 1: Lego Door Knob

Materials needed:

      Legos (this one was made with all 2x4 and 2x2 bricks)
     Marker
      Ruler
      CA glue (or epoxy)
      Putty
      Brad Point Drill bits

Step 1:
        Layout your legos in a pattern that is colorful and close to shape of door knob
      (you can get much more creative if you have different shaped bricks)

Step 2: Lego Door Knob

Step 2:

     Glue together your legos (skuff sand bricks for a better glue bond)

     Have a napkin near by to remove squeeze out as quickly as possible

    Glue the bottoms to help with strength.

Step 3: Lego Door Knob

Step 3:

Layout knob and glue together

Step 4: Lego Door Know

Step 4:

     Fill the center section with putty (Durhams water putty is real strong)

   This area will be where the new knob will connect to the old.

   I replacing the inside knob since it has no spring to try to recreate.

Step 5: Lego Door Knob

Step 5:

     As putty hardens up you can slide the center bar into make a snug fit.

     If you wait to long a 3/8" hole does a good job.

Step 6: Lego Door Knob

Step 6:

Transfer hole locations from original door know and drill them out with a brad point bit to avoid bit wandering.

Step 7: Lego Door Knob

Step 7:

Attach new baseplate to door just like you would a regular door knob.

Make sure glue is dry before trying to tighten to much.

Step 8: Lego Door Knob

Step 8:

Adjust depth of center hole to proper depth.

Step 9: Lego Door Knob

Step 9:

Screws are now hidden. Make sure you left clearance to turn knob without sticking.

Step 10: Lego Door Knob

     Hints I have found during building:

              - Make sure you completly cover the old door knob hole
              - One of the knobs has a spring, so make sure to keep that one (it can be switched to the inside of the room if desired)
              - A standard door knob set is made of knobs that connect together and squeeze tight on the door. This one involves a seperate baseplate. Because of this you may need to glue the center shaft onto the knobs (use something removable if you need to work on the door knob)
