Introduction: Concrete Lamp (1)
Hi! Let's see how to make one of these concrete lamps.
Ok, let's start. Connect the wires to a toggle switch.
Apply super glue around and on the top of the switch. That will prevent water from penetrating into the switch.
Insulate everything with plenty of 3M Industrial Adhesive or rubber to metal adhesive.
Wrap everything in 3M electrical tape or equivalent, then let it all dry.
Wrap it again and again and again... Water must be kept away from the switch, so be very careful with that!
Get yourself an E27 plastic socket, make a 4mm hole for the cables, then connect them.
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...
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.
The bulb will keep the socket in place. Don't overtight. Also at this step attach the switch and the power cord.
Fill the assembled mold with concrete and wait for a day.
Gently disassemble and remove mold.
Get some 150, 600 and 800 grit waterproof sandpapers. 150 is for making the bottom smooth.
Fine sand and polish the surface with the 600 and 800 grit sandpapers and water.
Then attach the nuts, washers and plug.
Attach a bulb, your new lamp is now ready!
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.
