Est. project time: 15min plus glue dry time
Step 1: Lego Door Knob
Legos (this one was made with all 2x4 and 2x2 bricks)
CA glue (or epoxy)
Brad Point Drill bits
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
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
Layout knob and glue together
Step 4: Lego Door Know
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
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
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
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
Adjust depth of center hole to proper depth.
Step 9: Lego Door Knob
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)
