You can also try to fit a square crop around the plate, and see if there&#039;s a gap on one side.</p><p><br /></p><p>How the photo is taken can of course affect this. But if the picture he provided shows the diameter the same across the plate no matter where it&#039;s measured, then that&#039;s a strong indication the plate is true in circular dimension.[/QUOTE]</p><p><br /></p>
