This project, if I were to do it, would hopefully improve a paper trimmer's ability to deliver consistent, precise cuts to specific measurements.
I developed the urge to do this project after using my existing paper trimmer in the making of my postcards, which came out about the right size but with some variation. I think having hard stops rather than just grid lines might help solve the variation problem.
I don't really have the time or the severity of need to do this project, but it would be nice, so my brain has been hung up on it and I've been researching the heck out of it despite my conscious preference to not do the project.
Hopefully braindumping into this document will be the final step and I won't have to think about it again, at least until the next time I'm unhappy with what comes out of my paper trimmer.
