Art, it looks like each panel is curved.....so, does the studio fabricate a "curved" table/platform on which to work on the panels? and, probably a couple of different curves due to the size of the dome?? Thanks.

Barbara, we made a wood "envelope" that is curved to fit the panels, this is how the panels are lowered to the ground. The reverse side of the envelope will be used as a support in the truck to place the first panel against. The panel that you see is a metal angle frame with two integral T bars, the three leaded glass panels are set into the frame. The bottom two panels are compound curves; the base is a section of an arc, such as a latitude line, and the curve from the base to the top is a section of a parabolic arc. Typical, all leading work would be done flat, soldering the interior or obverse side of the panel first. If the curvature is severe enough, you would then bend the panel over a for and solder the upper or reverse side of the panel. This requires tucking of the leads or you will have quite a few gaps on the upside. This is a structural as well as an esthetic problem. These curves are gentle enough that they can probably be soldered on both sides and the curved over a form.

This project certainly requires that a studio can properly prepare for extracting the panels......and that would take some time..... to all the ducks in a row, so to speak......very interesting and when you get some of them on a table, if you could post some photos, that would be interesting.
