Hi everyone. This is my 1st instructable, even when is not my 1st diy project.

Please excuse my grammar, this is not my default language, but I hope the instructions and the photos being enough for understanding.

I hope to upload more projects, anytime soon!
Thanks for your visit!

Step 1: Materials - Materiales

First of all, we need to get the materials and tools for this project.

Most of it, I get it on a hardware store, and a few items, get them from and old, broken lamp (The Cone, the clamp and the piece of threaded pipe)

2 Inches width, PVC Pipe, as much as many arms you want, I use 25 cm for each arm

A Lamp Cone, or you can use a PVC Fitting adapter.

A Plastic Clamp, to hold your lamp on the edge of a table

2 PVC Caps, one for the clamp, and one for the cone, if you gonna use a fitting adapter, you can replace it with a 90° degress piece

Obviusly, a light bulb socket.

A light bulb maybe?

A piece of threaded pipe, wich goes on the socket, and trough the cone, and another one, wich goes between the PVC cap and the plastic clamp.

4 Locknuts to the threaded pipe, 2 for each piece

Screws, locknuts and washers. I use 2 washers for each Screw, you'll see the picture later

Step 2: The Light

Insert the threaded pipe inside the socket, then trough the cone and pute a locknot.

It should look like the last photo.

Step 3: Cutting the PVC Pipe for the Arms

First, draw a mark every 25 cm / 10 inches, on the PVC Pipe.

Use the HandSaw, to cut the pieces.

After that, use some sand paper to get a smooth finish.

Step 4: Making the Flat Shape for the Arms

This step, will be much easier with a soldering torch, but I don't have one, so I use my stove instead.

Keep the PVC spinning to avoid overmealted parts or black bubbles.

With a low flame, I keep it around 20 seconds spinning and then, using the edge of the counter and a hard drive, I press the PVC to close the gap, and get a straight edge.

Wait a few second to cold down, and put a washer over the flat PVC, to mark the hole in the center and the use the outside to make the edge curve.

Use a drill to the center hole, and the HandSaw to cut the edge arround your marks.
Make sure you left 2 PVC parts, with one end rounded, where goes the PVC caps.

Step 5: Building the Articulation

Split the flat side of one PVC piece, and insert in between, the flat side of another one

Put a washer on one side of the screw, the screw inside the center hole, another washer on the other side, and close it with a locknut.

Step 6: The PVC Caps

Lets start with the clamp side.

The clamp I had, already have a hole for the original lamp.

So, you just need to drill a hole on one of the sides, and then, put a piece of threaded pipe inside the hole and the PVC cap.

Put a washer on each side of the pipe, and close it with a locknut on heach side.

In the cone side, put the threaded pipe inside the cap, and the cone to get a 90° degress shape, and secure it with washers and lock nuts on each side.

Step 7: The Electronics

Now is time to make the electrical part.

This is a very simple circuit, just the light bulb, a switch to on/off the light, and the electrical plug, all in series.

Make sure you left anough cable to connect your lamp anywhere.

Step 8: Finished!

And thats all folks!

Just plug the lamp, turn it on, and enjoy!

I make all this instructable, with hand tools, that everyone could just have around, and the cheapest way possible.

Either way, any comment or recomendation, will be appreciated.

    Alhaxxor, glad you like it.

    I think, considering the weight, you should add a couple of strings to reinforce the strength of the articulations

    I've been looking for a good cheap articulating arm to mount a computer monitor. I'll give this a try. thanks for the 'ible!

    Very cool! It looks a little like the arm on the space shuttle... if you squint.
