I was able to initially get the ring pretty close to exactly round with the hacksaw and a file, and I finished it off once I had the ring mounted on the crank. With the bike on a solid workstand I got my wife to turn the cranks while I used a succession of files. I did this before I had derailleurs mounted and chain installed, and I could brace my hands against the the seat-tube and down-tube to hold the file as still as possible. If I'd had a Dremel with a drum band sanding attachment I probably could have done the same considerably quicker. For the amount of fiddling around, next time I think I'll just buy a chainguard, so long as I can find one to match the crank - Rivendell sell some quite nice looking ones.
