If you make this one, then there are templates for the Stained Glass Coke logo and a bending guide for the paper clip shade frame available as a download from dadcando, where you'll find a little more about the project and Louis Comfort Tiffany, the inventor of the Tiffany Lamp.
- table tennis ball
- paper clip
- old small paintbrush
- three copper or silver coins of different sizes
- a cheap mini USB PC LED light
- coloured permanent markers (or translucent paint)
- fine black permanent marker (or embossing craft pen if you have it)
- Super Glue (or quick setting epoxy resin (two part glue)
- Hot melt glue gun glue (or quick setting epoxy resin)
- Pliers (thin nose ones would be useful)
Step 1: Draw Out Your Lamp Shade Design on the Ball
Start by drawing a line round the equator of the ball. Use the seam as a guide. Then from the North Pole draw lines down to meet the equator at the quarter hours so that you have four equal segments. Now further divide each of those segments into three small equal sized segments so that in all you have 12 segments.
about 2 to 3 mm below the equator line draw another line round the circumference. Between this line and the equator draw a series of vertical lines that line up with the ends of the segment lines.
Below the lower circumference line draw little scallops round to line up with the small vertical lines.
About 10mm down from the North pole draw two concentric circumference lines.
Draw out the Coca-Cola logo. I used the reference photo and a coke can as the guide, but now I have drawn them up properly and you can download them from dadcando Tiffany Lamp project as well if you want.
I simplified the logo mainly because of the small size and the complexity was at the limit of my skill and the equipment i had. (I made this for my kids while on holiday staying in someone else's house so I didn't have much in the way of equipment.
Step 2: Colour in the Stained Glass Pattern
Don't worry if the colouring in is a bit streaky, real stained glass looks just like that, it is never an even colour at all.
The photo shows the back of the lampshade. you'll notice that this logo looks slightly different to the finished one. When i drew out the front logo I didn't leave quite enough space for a second complete one so I squashed up the logo on the back slightly, by taking out the dash between Coca and Cola.
I took this photo to show the colouring stage after I had already outlined the logo in black on the front. Anyway, this gives you a good idea of how naff it starts out looking. It's only when you line it in in the next step that it starts to look cool.
Lastly when leaving the white err on the side of more rather than less. the black line will take up quite a bit of space at this scale so you need more white than you would think which means that the letter have to be a bit chunkier than they are in reality. Also remember that the original wasn't perfect, it was made from scraps of glass left over from Tiffany's window projects. that's what makes it look so natural and each one so original.
Step 3: Line in the "stained Glass"
I found an embossing pen at a local craft store, which doesn't give a very deep emboss, but does give quite a credible effect. Mind you a fine black marker would have easily done the job, and the embossing pen did try to blob a bit... this was my second attempt after i slightly messed up on the first one.
Notice that I have put lines across the white areas to break up the letters. In real life the lamp is made of stained glass and if you have ever tried to break glass you will know that you have to be a genius to get curved pieces. Well they were very clever at breaking the glass, but they still broke up into manageable pieces and then stitched it back together with copper or lead strips, so that is the authentic look you are going for.
Step 4: Cut Out the Lampshade
using a craft knife cut a very small slot in the top of the shade, right at the North Pole about 1 mm wide and 2mm long
Step 5: Make the Base
Glue them together using super glue (cyanoacrylate) (be very very careful with super glue as it sticks skin permanently and instantly (it was designed as a tissue glue). I like it because it is quick (even quicker if you use accelerator) but you could use two part epoxy resin especially the rapid setting 90 second stuff. make sure the that coins are concentric and all centred properly.
Once they are stuck together colour them in with a permanent marker, spray or paint them black.
Then sandpaper off the corners a bit with a very fine grade of sandpaper or preferably wet and dry. I used p600.
Lastly I drilled a small hole part way into the top of the top coin to give the glue that I was going to use to attach the stem something to grip on to (see next step)
Step 6: Make the Stem
Getting the bristles out was harder than I expected. Before you take the handle outgrip the metal ferule about half way along it with pliers where the jaws have been wrapped in a kitchen cloth (to avoid scratching the metal) and grip the bristles with another pair of pliers and firmly pull out the bristles. You might have to pull the bristles back and forth quite a few times to get them to all come out.
When the bristles are out, try and pull out the handle. Or better still saw or snap it off at the ferule and then drill in to the wooden handle a few time with a little drill bit from both ends until you can pull out the scrap.
Once the ferule is empty, using pliers turn up a small part of the wider end. This will accommodate the wire from the LED in a few step's time.
Step 7: Prepare the LED Part
Slip the lens off the other end of the lamp and ease out the LED, still attached to its wire (it will also have a tiny little resistor soldered in line with one of the wires.
keep the lens and the USB plug to one side. You can throw away the outer springy sheath or keep it for another project.
Step 8: Make the Lampshade Holder
use small pliers if you have them and hold the paper clip firmly just in front of where you want to bend and then slowly bend the clip into to shape. It really helps if you mark out the bends before you start. bending a paper clip too much will fatigue the metal and it will snap. Fortunately this step is quick and paper clips are cheap so if it breaks learn from that and start over.
Step 9: Assemble Stem and LED
Insert the lampshade support frame and arrange them so that the LED sits nicely in the middle of the frame.
Holding the stem, the frame and the LED with a piece of tissue (it will get hot) squirt some hot melt down inside the stem to secure them. Before it sets make sure that the wire is draped over the rim of the bottom of the stem where you make your small indent.
Trim off any excess glue, making sure NOT to cut the wires by mistake.
Glue the stem to the coin base. I used Super Glue again here, but you could just as easily use two part epoxy resin.
Step 10: Hack USB Plug and Attach to LED Wires
Remove any rubbery bits and disassemble the plug's inner plastic housing. You will most likely pull off the wires in taking it all apart but no worries, you are going to solder the wires back on. Use the diagram to show you which pin to solder the red and black one to.
reassemble the plug using some hot melt when you put the metal case back on to pot the assembly and then slip the rubber outer back round the metal plug chassis and glue up with Super Glue (it is very good for this and sticks the plug rubber perfectly.
Back fill the plug with a little bit of hot melt to pot the plug up completely.
trim off any glue the squeezed out and use black marker to cover up any white Super Glue residue along the USB plug seam.
Step 11: Fit the Tiffany Lampshade
Extra finishing touches are twisting the wire to make it neat, or twisting the wire and then spraying it black or brown for a really authentic look. The wire is nice and thin so really looks the right scale.
As I wanted to copy the reference photo, I made a miniature can of Coke too. There's a dadcando project which has instructions and label printables which can be found at the micro tin can project.
The lamp looks really nice and has a lovely weight to it. Next I think I am going to make a Chinese lantern shade from thin strips of bamboo and tissue paper to fit over this lamp assembly so that i can change the lampshade when I feel like it, but I must say, all manner of miniature funky lampshades come to mind.
Anyway, good luck and have fun making this little project.
