Week 3 has begun and the task of grinding has become much easier. We have a reciprocating saw with an attachment that allows for us to file and grind the plastic. This was a new experience for all of us although I have used power tools before, plastic has proven itself to be a stubborn material. It took me half an hour to find the right speed, and direction to grind the plastic to be effective and collect the samples. Grinding too slow and the plastic wouldn't budge, grinding too fast and the heat from the friction caused the plastic to reform rather than shred. Yet in the end I found a effective way to grind away my day.
