I recently acquired this old beast of a manual paper cutter, and am stoked on finally being able to cut in-house!
Works great, but there is one kinda-major issue that I can't seem to get around: I can't seem to square up the backstop. What I mean is, when I'm facing the front of the machine and the paper is on the bed, I push the stack up against the backstop and the right sidewall, but if you look at the left end of the backstop, the stack is about 1/8"-1/4" off. In other words, the backstop isn't at a perfect right-angle to the rest of the bed/sidewalls. If my description is confusing, here's a diagram to illustrate:
Problem is, I can't seem to figure out how to square it up. There is a bolt (A) on the back of the backstop, but it just holds the backstop to the undercarriage assembly - doesn't adjust anything. Then, there is this double-bolt thingy (B) that looks like it might do something, except that the bolts are so tight/rusted/sealed on there, that I can't loosen them to even find out if it works. I'm also scared to try, and skeptical about it even working because just looking at them, they don't seem to adjust the rotation of the backstop at all.
By the way, I know for sure that the paper itself is square because ALL of the papers I've tried are the same amount out-of-square (different papers, different brands, etc.). It's definitely the machine.
Other than that, I'm out of ideas. Anyone know anything about these things? Am I just S.O.L.?
