I just got the alto's used and I am having a little trouble with the ruler moving. It seems there is a little play from one end to the other when lining up the numbers.
It appears to me there is some movement in the area that sets on the groove...more on the metal one that the plastic one on the long end.
If I am making any sense at all- does anyone have this problem? I need to find a remedy, because my cuts are off sometimes.
