Going in for the easy layup

Aung, Dat, Sheetal and I were up till around midnight last night laying up the torsional test samples. It was quite an adventure as we had to MacGyver a hot wire rig together. Since we have quite a bit of foam cutting ahead, today we'll work on putting together a better wire setup. Aung and I cut this foam by pulling on a wire between us while Dat bravely held the wire to the terminals of an RC starter battery.

The one on the right has just one layer of 3.7oz glass and the one on the left has about 20 diagonal wraps of carbon tow under the same layer of glass. The control is in the center.

Saturday morning they will be cured and we'll test against the control. I'm betting there won't be a dramatic difference between the two and that neither will be stiff enough without another layer. But then, what the heck do I know?
