For the glueing of the tensile plates to the beams we opted to use Superglue as it will bond platic to chemiwood instantly. Tom completed this exercise. We decided that for the tensile rods we would use 2mm plexiglas rod, over this slides another rod which the glazing compression plates are fixed to which we chose 3mm plexi glass rod for. We decided that to achieve the detail then we would have to drill 2mm holes into the 3mm rod. After Toms many failed attempts with a rotary tool, I opted to try myself using a pin vice. I used the jig that Tom had made to mark on the rod where the hole was needed. I then drilled through with a 0.5mm drill bit, followed by a 1.5mm drill bit and then finishing off with a 2mm drill bit. I was finding that drilling by hand was allowing me the control and precision to get the holes exactly central (with 0.5mm each side), the plexiglas wasnt melting like it did with the heat generated by the rotary tool. Although many of the rods were snapping with the last few turns of the pin vice. I was producing 1 unbroken rod to 4 breakages. I decided to swap the drill bit that Tom had picked. This proved to be the problem, the drill bit was blunt, I was hardly getting any breakages now.
