I've fallen into a pattern.



So, here is the pattern beside my work area. I've numbered everything to avoid confusion later.



The first panel is almost completed foiled. (I must grind for a perfect fit.)



Here are some of the tools I use for copper foiling. Black-backed adhesive copper foil (1.25mm x 7/32".), some good scissors, an oil-based permanent marker and my "foil finisher". The work surface is 3/4" plywood scrap. Notice how the glass parts must fit together inside the template area. If I don't keep each panel exactly the same size I could end up with crooked lamps. That just won't work!



Here's the finished product. I have to say, I like this one better than the first. I was in a rush to finish the base because I entered both lamps into an art show (non-juried). My wood selection at the time was poplar or nothing. So I chose poplar! Most home centers have lumber sections where you can buy pine, fir, red oak and poplar already "surfaced" and ready for your project. I had some leftover poplar from a previous project and it did the job.

All the leaves are gone.

The Chickadee Light Box was my third stained glass project and my first attempt at a lamp. It turned out better than I could have imagined. I love to turn on the light and just sit in the room with it glowing in the corner. (Maybe that's a little weird, I admit. But the soft light is peaceful.) The chickadees happily guard the entry of my house.

I've basked in the glory of my first successful lamp long enough. I figure that it's time to get on with the next one. I had the idea for a fall leaves lamp at the same time as the chickadees design. (Again, thank you to Ichiro Tashiro for his inspiring work.) So last fall, I wandered around my yard and took some snapshots of my maple trees.



I first thought a "realistic" leaf was the way to go. But as I studied the outlines of "real" leaves, I thought better of it real quick. There are a lot of curves and overlapping parts. I know my limitations. My stained glass experience was not up to the task of creating 6-8 realistic leaves. Especially when I'm building a complicated three-dimensional lamp.

Instead, I traced the outline of a leaf photo that I liked and made a posterboard cut-out of it. I actually made three identical cut-outs.

Once I drew the borders of the lamp panel (6" x 9") I played around with the placement of the leaves. When I was happy, I traced around the leaf cutouts and moved on to the next panel of the lamp. All the while I'm thinking about how the glass will cut and grind. I could easily design myself into a corner, making pieces that would be very difficult to reproduce.

As you can see, the first panel is completed. I'm taking cues from panel #1 to design panel #2. These panels will make one corner of the lamp. On the fly, I decided to take curves out of the design. Instead, I've gone over the leaf tracings with a ruler to straighten every curve.

Now all four panels are designed and labeled. I will photocopy them for safekeeping. My next step is to transfer each panel design to poster board. I will then number and cut out all the pieces using my foiling shears.

Tuning up the brass section.



I picked up these brass parts at a local hobby shop. They are .016 inches thick x 12 inches long. The large set is two inches wide; the small set is one inch. These pieces will make the metal part of the base that fits into the wooden base. Clear as mud, right?




I carefully cut two of the one-inch brass pieces into six inch lengths.



After cleaning them up with 150 grit sandpaper, I will add the tinning. (I don't know if I'm saying this right. All I'm going to do is cover the pieces with a thin coat of solder.)



First brass piece, partially tinned.



Here are all four brass pieces completely covered in solder and ready to apply to the lamp.



I am now about to solder the first two brass parts to the botton of the lamp. This section of brass will eventually make a sturdy base that will easily support the weight of the glass lamp.



The second pair of one-inch brass parts overlap the first. I will solder them all together. The solder lines that connect the brass parts to each other will not be noticed once the lamp is assembled. However, the solder lines where the brass and the lamp connect will be noticeable. Keep them nice and tidy. (But don't look to closely at mine!)



This section of brass pictured above (I call it the "slip") will eventually slide into a rabbet cut into the wooden base. It will provide stability for the heavy glass but it must be fitted precisely.

After cleaning them up with 150 grit sandpaper, I took two of the twelve-inch long and two-inch wide parts and bent them in my vise. I bent each piece so that it would have two five-inch long sides and one two-inch long side. It looked like an unfinished "U" when it was all said and done.

These two pieces are "clamped" together with paper clips and centered so that there is 1/2 of an inch showing all around. I soldered the two matching pieces together. Then I tinned the upper half of the "slip" and soldered it into place.


Next time I will start on the wooden base. I have some really nice figured Walnut that I salvaged from becoming firewood!

Scritch scratch I was making a lamp.

An unusual peace has descended upon the shop. The table saw has been quiet for several days now. There is still work being done. But replacing the saw's loud grumbling is a soft, gritty scratching noise. A sound that I can only describe as what a fistful of gravel would sound like when scraped across a chalkboard. Anyone who has ever cut glass will know the sound well.

In a previous post I described my last stained glass project, a rendering of my antique hand plane. In that post I only touched on some of the techniques that I used to create the stained glass panel. This time, I've taken more photographs and will explain in more detail how this project will come together.

So, what is the new project? My new project is a lamp. Notice, I didn't say lampshade. There are plenty of stained glass lampshades out there. They are attractive and many are complementary with Arts & Crafts design. But this lamp is altogether different from anything I had seen before. You'll see what I mean as the lamp comes together.

Before I get ahead of myself, let me give credit where credit is due. The original piece that inspired this project was created by an extremely talented glass artist named Ichiro Tashiro of Japan. I borrowed heavily from Mr. Tashiro's work in the making of this lamp.

Let's start with the images. This lamp has four glass sides and a glass top. The glass portion will sit snugly in a wooden base. The four glass sides will have images. In this case I chose birds.




These are black-capped chickadees. I chose them for this project because they are common all across the northern part of the United States, and because they are active and cute.

Using a common ink-jet printer, I sized and printed black and white versions of these photographs. Now is a good time to talk about size. I had already decided how large the lamp and its base was going to be. In this case, I wanted each panel to be 6 inches wide. I also wanted the wooden base to be a square of 6 inches. Using the "golden rectangle" ratio of 1:1.6, I made the glass panel height 9.75 inches. (6 x 1.6 = 9.6) OK. So I rounded up a little on the math. It will look fine, trust me.

After figuring out the specific dimensions for each glass panel I determined how large the birds should be for a pleasing design. I also chose which direction the birds would face and the layout of the branches. Only two sides of a square object can be see at one time (I'm not counting the top as a side.) Therefore, only two sides of the lamp will have a detailed image of birds. The other two sides will probably face a wall, much like I did when I misbehaved in kindergarten.

Using expert drafting equipment of a ruler, a pencil, a carpenter's square, and a sheet of paper, I was able to lay out the 6 x 9.75 inch panels. From the black and white prints I traced pencil outlines of the birds' prominent features and the twigs they are perched upon.





After making the simple pencil sketch, I went over the drawing another time with a pencil and ruler, making my lines straight. I thought the panel would look better that way. You be the judge.
