Measuring mine, it is exactly 57 1/2" diameter from the edge of the roadbeds. For a corner, you would need to come out 17" from the center of the corner at the wall, so the apex of the curve would stay on your shelf. (Your walls meet and make a 90 degree angle. If you come straight out at a 45, you need to come out 17 inches to keep the track on the shelf)
You could always lay it out in SCARM, it's a free program, and figure out your measurements!
Good luck!
Thanks for the info! Looks like the 054 won't need built out quite as much as the 072. From the center of the corner I'm at around 22" for the 072. Currently from the corner I have the shelf built out about 13.5" for the 031 so it would have to come out a good ways for 072. If the 054 is 17" from the center of corner I'm guessing the 042 would probably be around 15" maybe? You wouldn't happen to have 3 sections of 042 that you could measure?
