I swear, I *did* a Google search for "3 ring binder mechanisms", and found
only places that would sell you 3 ring binders with mechanisms, or places in
Asia where I could buy 100,000 of them if I wanted.
I apologize, profusely.
The search is now on for a good quality mechanism, where the rings meet
evenly, that kinda thing.
And for those who were wondering...
The way things have worked so far is to print up the music on 11"x 17" paper
with a 3-and-a-bit inch bottom margin, and trim to 11"x 14". I don't know
why 14" and not 17", I wasn't privy to the original arrangements.
The paper is then punched as though it was 8 1/2"x 11", with the holes
indexed from the bottom inside corner. A standard 3-ring mechanism will
work fine, so long as it's a 1" ring. With bigger rings, the trigger fouls
on the paper.
The printout binders take 14 7/8"x 11" paper, and I need to bind on the long
edge, so that doesn't quite work, but a good thought.
And yeah, one can buy an 11"x 17" binder, but $75?!?! Yikes.
