Changes

I think the screws may have been too loose to begin with, but they may have loosened further during polishing. In the future I have to make sure the screws are tight enough and keep checking them from time to time so they won't loosen and let the fibers slip.

3/15: I talked with Jim about polishing today. He said that if you change the twisting even at the end with finer grits, it can present a much different surface area to the paper than previously. If the fibers are twisted consistently and then changed, there may be a much smaller area of contact and therefore a much higher pressure than before. The higher pressure may melt the fibers. Also, it is not good to blow on the fibers because of the moisture in breath.
