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.

K was free to work on this with me and we drew out the hexagon in illustrator and made clearance for the rods, added in some circles for the soldering and then engraved it onto a base piece of wood – this was important as I was so see, when cutting out the laser ply, the pieces all came apart and we needed a base to re-attach them. This we did by keeping all the plywood triangles and using double sided tape to attach them. Then I filed the rods down to exact size and drill out the holes for the vertices/solder.

The felted geo-dome is imagined as a musical/fabric interface that engages haptic responses for bodily interaction.
