I know we're talking about 1mm here, a bit less really, and I couldn't really say it looked "wrong" or out-of-proportion, but somehow it doesn't look exactly right, and I didn't know the door was a little narrow. How can we spot something off that little? I know if I hold and look at a #79 drill bit and a #80 at the same time, I can tell the difference. I've always thought the old MDC boxcar doors(50' sliding door) looked "off". I don't know if they're narrow, wide, or right-on, honestly. ??? What's with the eye and the brain?
