Introduction: Concrete Lamp (1)
Hi! Let's see how to make one of these concrete lamps.
Step 1:
Ok, let's start. Connect the wires to a toggle switch.
Step 2:
Apply super glue around and on the top of the switch. That will prevent water from penetrating into the switch.
Step 3:
Insulate everything with plenty of 3M Industrial Adhesive or rubber to metal adhesive.
Step 4:
Wrap everything in 3M electrical tape or equivalent, then let it all dry.
Step 5:
Wrap it again and again and again... Water must be kept away from the switch, so be very careful with that!
Step 6:
Get yourself an E27 plastic socket, make a 4mm hole for the cables, then connect them.
Step 7:
Assemble socket and again be sure you glue and insulate every part so water won't get in. Careful with that!
Just my two cents...
Step 8:
For this lamp I used a custom made mold from 3mm laser-cut acrylic sheets with holes predrilled. A 28mm hole for the socket, a 14mm hole for the cord (I used a M10x1.5mm hex Nut relief cord grip) and a 10mm hole for the switch.
But instead you can use any kind of food storage plastic box, flower pots, plastic jars, anything you like and a reamer.
Step 9:
The bulb will keep the socket in place. Don't overtight. Also at this step attach the switch and the power cord.
Step 10:
Concrete.
Step 11:
Fill the assembled mold with concrete and wait for a day.
Step 12:
Gently disassemble and remove mold.
Get some 150, 600 and 800 grit waterproof sandpapers. 150 is for making the bottom smooth.
Step 13:
Fine sand and polish the surface with the 600 and 800 grit sandpapers and water.
Then attach the nuts, washers and plug.
Step 14:
Attach a bulb, your new lamp is now ready!
Step 15:
Then a few days later I decided to sand the surface to look more "concrete". I also added the "on-off" label. So here is how it looks now.

Were you able to reuse the acrylic?

Yes, many times, unless I glue it.

nice, question, if the toggle switch goes bad, can you remove it?

Well, obviously no parts can be removed or replaced.
