As usual, I had bought the first saw vice that flung itself in my path. I
got it home to discover that the jaws not only were somewhat misaligned,
but had a nice gap in the middle ( I swear these deformities take place on
the car ride home). I took an old bike inner tube and made a pair of
leggings for my vice. Stuck them on with some spray adhesive. The rubber
fills up the gap nicely, and also serves to dampen the filing noise.
