Making an arch

Okay, so I'm designing a structure and I'd like to have an arch shape to stick between support beams or whatnot.

This is what I'm trying to do; I'm making a 32-segment disk, then making another 32-segment disk, slightly smaller so it can fit perfectly inside the original disk. Then, selecting first the original and then the second, I'm trying to do Boolean operations on them. They are, apparently, ending in absolute disaster. Vertexes become unhinged, random pieces are deleted, the shape collapses on itself, and other geometric horrors. Obviously I'm doing this wrong.

is there an easier way to make an arch? I don't want to draw one free-hand; that would take far too long and look horrible.
