How long has some of your largest projects taken?

If it was 6 or more hours and you had to switch bits, did you let it cool for a while before putting in the other bit? Any problems with doing that or is it better just to let it go the full length and then let it cool down completely after the project is done?

I've run some extremely long projects, pauseing long enough only to change boards. The bit never got really hot. I think the only item to watch for is the flex shaft, and if properly lubed will stay within a normal heat range.
