I’ve been considering the technical challenges of fabricating the penguin weathervane. Although it was clear that the best approach would be to laser-cut the design from brass or copper sheet, I needed to work out the best way of setting the coloured glass panels into the structure.
After discussing the issue, I felt the best approach would be to cut a 4mm central brass sheet rebated by 4mm around the glass panels, which would themselves be oversized by approximately 3mm. On each side of the brass sheet, additional fish and penguin laser-cut 1mm copper panels will be used to retain the glass. The three layers will be held together with brass leather screws and the glass panels silicone bonded.
