2015-05-31 (Su) Wind Generator Turbine Design Tests

Bisecting bottles was shown to be tedious work yesterday. Straight cuts on the sides and a rounded cut near the nozzle were easily done with a razor or scissors but the thick plastic at the bottom of the bottle required a saw. A hacksaw was tried but a dull blade made for slow work. After a trip to a hardware store more options were purchased. New 24TPI (teeth per inch) hacksaw blades were purchased as well as a reciprocating saw blade with 18TPI, and a saw blade with 6 TPI. Qualitative testing said that the 18TPI saw blade was the fastest way to saw through the bottom of the bottles.

Ten bottles were bisected using the different saw blades. The total time was a couple hours. Manual sawing was definitely possible but a motorized saw would have likely produced more repeatable results in less time.
