Sketch Modelling

got some foam modelling in the workshop done today. I wanted to test out the different possible shapes for the handle of Lifeline. 

Based on the optimum power grip diameter of 1''-2'' I cut out 3 different sizes of foam hexagon which I will be testing using ice and cold water later on alongside a handy baseball bat as a round grip and also some steel tubing taped together as an ovalised tube.

I will also be handing these out to people with varying sized hands over the next few days and asking them to pick the one that feels best. The idea is that if their responses converge on a similar size and I agree with that after freezing my hand and trying them again then I will have found something close to good for the average person. 

I won't be asking anyone to participate with the ice water experiment because I'm pretty confident it'll hurt.
