Geodesic Dome: Welding, jigs and felt

The production of a ‘jig’ allowed me to weld the corners of the rods together in position around either a hexagon or pentagon. The way we went about this was to draw an image of the hexagon, cut the rods to size to make the outer edges of the hex first, then to drill down and makes holes around the vertices and room for soldering.
As I began to use the bandsaw and the result of this showed that the template of the jig using tiny pieces of wood to create spaces for the rods and tacking them in was quite clumsy – so instead he came up with the idea to laser cut a jig, being much more accurate, reusable and easier – instead of tacking lots of little pieces of wood, I could tack a couple of sheets of ply to a base wooden base that had been laser etched with the hexagon outlines.…
