Glass Kites - Is Gravity Our Friend ?

I will insert some photos of the stained glass kites I made and tell the tale of woe.

Garden glass up in the sky. Catching the full sun or floating gently in the shade. But rugged enough to withstand the storms and tempests. That's where the idea began.

I made several sizes of kites in the basic kite shape such as the one to the right (titled "Storm Kite"). The proportions of height to width affected their aesthetics and their aerodynamics. I always hung them at a jaunty angle, just as they would be in the sky.

They were all regular kite size. From 21" - 28" tall and 16" -24" wide. I hung them on chain, with a heavy-duty brass fishing swivel. And they looked grand.

I also did a nice box kite. It was my first experiment with exposing different metals to the elements. In "Box Kite" I tried aluminum and steel as well as brass.

I learned a lot about anchoring in solder joints and how different reinforcing materials worked. I also experimented with the different glass finishes they sell. Most products are designed for indoor use, and I had to figure in UV exposure. So I'd try different things and watch for a year.

We had several hurricane remnants roar through the Blue Ridge Mts. during this two year test period. We had winds of 35mph numerous times, and got up to 55+ one day. The kites danced and swang and flashed around in arcs.

The storms tested the kites. But I liked them best on those afternoons with soft breezes, as they twisted around on their swivels, winking diamonds of light.

Alas, the truth began to emerge. The fatal flaw in the whole Glass Kite endeavor. Trees provide shade, and stained glass looks best in the sun.

At first I had a few prime branches that were the perfect anchoring sites. High enough off the ground, extending out away from the tree into the sun, not surrounded by other branches, and stout enough to lean my extension ladder against.

That lucky combination proved both short-lived and rare. The branches that are not surrounded by others are usually the last branches to go from a diseased side trunk. A good strong wind and the cradle will fall. Or the kite in this instance. I lost more glass kites to limb failure than to structural problems with the kites.

So I now have no limbs that would be good, sunny spots. If I had a cherry picker/bucket lift, I would do some cables between trees. But then I'd have the headache of tree sway. Well.... into the design book for later.
