Industrial Copper And Concrete Lamp

This is a relatively easy and inexpensive lighting project that adds a clean industrial look to any room.
The first step is to create the box. This is made out of melamine and is 250mm x 150mm x 35mm.
Drill pilot holes when screwing the box together to ensure the melamine doesn't swell or split. The box should be as tight as possible.
On one of the walls drill a hole just big enough to fit some copper pipe through. I used a spade bit to drill this out.
Next you'll cut the copper pipe using a pipe cutter and glue it together using 5 minute epoxy. The idea is to create at least a T shape inside the concrete because this helps lock the pipe in and stops it from rocking side to side or back and forth.
Make sure not to add too much pipe or the concrete will not be substantial enough. Use just enough t joints or elbows to hold the lamp steady.
Once the glue has dried mix up some concrete. Place the pipe assembly into the box and fill to the top with concrete.
Tap the sides and bottom of the mould to remove as many bubbles as possible. After an hour the concrete will be in a state that the top can be troweled smooth. The top surface will be the top of the lamp so spend some time getting it to the finish you want.
After a day or two you can remove the mould, by unscrewing it. and let the concrete finish drying.
The base is made of plywood. Once the concrete has dried place it onto the plywood and trace it's shape. Now cut the plywood to that shape and sand any rough edges. The concrete can be glued to the plywood using silicone caulk.
Once that dries apply a finish to the concrete. This step is optional but it does help to make the finished product look more professional. I used a lacquer based sealant as it builds up to a thick finish.
Once the sealant is dry you can build the top assembly of the copper, out of 2 elbows and a straight length. Aim to get the last elbow roughly centred between the front of the concrete and the main upright. Again, this is all glued together using epoxy.
Before gluing the copper pipe together feed the lamp wire through. In my case I used a pre-made socket/wire kit but you could wire it up yourself if you were comfortable doing that. I used some silicone spray and a wire coat hanger to help pull the wire through.
Then finish it all off with a spray coat of clean varnish. This will ensure the copper doesn't tarnish, unless you want it to look aged.

    just need a bit of clarification - in one picture you show the copper laying flat inside the box (before concrete) and it even appears as if it's going through the box...? then you state that it should be put into the box. HOWEVER - the next picture has concrete being poured and the copper pipe is upright??

    Could this be made into a floor lamp as well? Would the base need to be made longer and wider for greater support? Or would building up the thickness suffice to prevent it from tipping over?

    I love it but does it give much light.?

      Turn off your sound or do you want instructions to do that

    I love this lamp and it matches with my Decor. I love that I just glue the copper instead of using stitch etc. I love concrete and copper together!
