This project uses a blue water bottle with the bottom cut out for a lampshade and standard plumbing fittings for the base. It casts a lovely blue light with some direct light reflecting off the table top. It has an inline dimmer switch. It uses a bulb that has LED's but is made to resemble a squirrel cage bulb. If you prefer, you can easily swap out an incandescent squirrel cage bulb or even a straight long (fishtank) bulb.
Step 1: Parts and Tools
- Tools used
- screwdriver for the inline dimmer switch
- butane torch
- ice-water bucket
- lazy susan turn-table (optional but helpful)
- bottle-cutting jig
- wire cutters
- drill with 1/4 inch metal bit and sanding disk with 60, 150, 220 grit or higher sanding paper
- plug and cord
- inline dimmer switch (optional)
- 1/2 plumbing fittings (create your own configuration). Mine used mostly 3" for the legs and for the uprights a total of 14" but you will have to adapt it to your own bottle's height
- 1/4 inch threaded pipe for the stem going into the bottle. Again, the length will depend on your bottle. Mine was 2 1/2 inches.
- 1/2 to 1/4 inch reducer
- two or more rubber washers for the top of the lamp socket to cushion it against the bottle
- lamp socket with 1/4 inch base
- Ikea LED Squirrel Cage Light bulb
Step 2: Cut the Bottle
- First score the bottle using a bottle cutter. There are a lot of different bottle cutting jigs. You can see mine. It is based on a design I saw here on Instructables.
- Fill a bucket with 5 inches of ice water
- use a butane torch to gently heat the bottle but turning it whilst holding the torch about 1 inch from the glass. You will begin to see the scoring whiten
- Plunge into the ice water
- Gently tap it on the side
- Keep repeating steps 3-5 until the bottom pops off. It should be rather smooth and not jagged.
Step 3: Sand the Bottle Until Smooth
- Begin with the 60 grit paper.
- USE EYE AND HAND PROTECTION AND WEAR A DUST MASK. YOU DON'T WANT TO BREATHE IN THE SILICA DUST!
- Hold the bottle flat against the sandpaper and continue to sand until you don't see any more shiny areas on the bottom of the bottle. Is should look like a smoothly polished glass surface.
- Tilt the bottle inward and outwards to sand the edges
- Repeat with 150 and 220 grit papers
Step 4: Build the Base
- Basically screw together the piping in any configuration that suits your fancy.
- You will need to disassemble parts when you pass the power cord thru.
- Drill a 1/4 inch hole in the upright to get the cord into the pipe and sand that through. You want no rough edges to snag the power cord
- pass the 1/4 inch pipe through the bottle neck and attach to the reducing fitting on top
- I wired an inline dimmer switch but you can use a simple on off or no switch at all
Step 5: Enjoy Your Creation
- It's a nice project
- It's a great gift
