I took the metal arms off the plastic base. I then drilled holes is a 2x4 base at different widths. The arms are now straight vertical and I have not had any problems since.

O.K. I'll bite.
Given the fact that the GP machine has it's balance points on two ball swivels, and the pads are free to float with no interferance from the rods, and given that the only purpose of the rods/arms are to keep your plane off the work surface, exactly what is the difference if they are vertical or angled?
