Lounge Work Lamp

These images show the work lamp I made for my wife. The base is a tripod based on 3 steel disks I picked up in the rubble of a local historic building that burnt down in February 2005. The lamp is designed to stand behind the couch and extend far enough forward to illuminate beadwork on the persons lap.

The head can swivel to point almost anywhere. The arm is counterweighted so it stays where it is put without straining the friction fit in the fork. The counterwweight is a wheel hub from a go-kart. It is still short of its coat of rust converter in these images.

The horizontal arm and counterweight. The fork can rotate in the vertical pipe. The counterweight will be painted shortly. The weight is adjustable for balance, though I did drill the axle hole on the balance point to start with. The is friction in the fork, created firstly by welding the vertical plates on with a bit of the square tube clamped between them, and secondly by the axel bolt being tightened up just enough.

Swiveling head created by cutting a fork in the end of the horizontal tube and hinging a block of steel in there. The block has a hole through it which in turn allows the angle iron lamp support to swivel. This gives a wide range of motion to the lamp. The lamp shroud is a pressed aluminum unit from a 1000watt stage lamp. The inside is no longer shiny, having been burnt to a murky grey surface byt the heat of the 1000watt lamp. I'm going to try painting it with automotive heat resistant chrome paint. An alternative is to glue a sheet of aluminum foil to the inside of the shroud.

The tripodal base. This was constructed entirely 'on the building board' in contrast to my normal practise of making a full working drawing before starting to cut material. The 'vertical' pipes are 10mm square tube. The disks were found in the rubble of a building that burnt down in February. This was a historical building, but I doubt the disks are any more than a few years old since the tenant was a 'Cash Crusader's (pawn shop with mostly new stock). I have not been able to figure out what they came from. They were lying near each other though.

You can see fotos of the fire and aftermath here and here (includes aerial shots from a microlight the next day) What it used to look like

Note that these fotos comprise the first set taken with my new digital camera! Yay! It is a Kodak DX7440 and jolly nice it is too. By the variation in lighting in the photos you can tell I was playing with the settings to see what I could achieve. These fotos have been reduced from the smallest size the camera produces, 1200x900 or 1.1 megapixels, and have lost some sharpness in the process.
