[thatch]

Recently, while doing some work on a friend's boat, I discovered a very creative way to make an "O" ring of sorts. Someone had wrapped about 25' of dental floss around a shift lever shaft that extended through a bulk-head, basically making an O-ring. It filled in a gap and most likely kept water from entering a space that had widened over the years. The floss still seemed to be in good shape despite having been exposed to the elements for quite some time. "Live and learn".
