Concrete Lamp (5)

Introduction: Concrete Lamp (5)

About: Just making concrete stuff for fun...

Hi! This time a little sweet concrete lamp instructable.

Step 1:

First of all find a good quality small food storage box. Use a soldering iron to make a approx. 30mm hole on the top and a 14mm hole on the side for the cord. (I use Lego bricks to find the center.)

Step 2:

Connect lamp cord (with plug and switch pre-installed) to an E27 socket. Use a chair protective pad to protect cord from bending.

Step 3:

Apply super glue or rubber adhesive before assembling socket

Step 4:

Insulate holes with rubber adhesive and secure socket on the mold with a bulb and a socket collar.

Step 5:

FIll it with concrete and give it 24h to dry.

Step 6:

Cut with a soldering iron and remove mold.

Step 7:

Water sand the bottom part with 100 or 150 grit sandpaper. You can also fine sand the body if you like with 600 grit sandpaper.

Step 8:

Attach protective rubber pads.

Step 9:

Ready. Install a bulb you like.

    I love the look of this lamp and the others you've made, but I can't help feeling the cable lets them down. I'd suggest either something that matches the industrial look of the concrete (say some orange outdoor type cable) or some cloth covered cable (following one of the various instructables like this

    BTW - what do you mean by water sanding, is it just as simple as moistening the surface before you use sandpaper, what is the purpose?

    Hi there!

    Well in most of my creations I use textile cables, but due to the fact that a beginner may find it hard to attach a switch, plug etc, in the tutorials I prefer an assembled one (even if I hate it myself). Please wait for my next one ;-)

    About wet sanding I mean to dip the sandpaper in water, sand, then wash it off with water, then sand again and again. Makes the surface much smoothier and no dust around!

    Thanks and happy Xmas,
