I'm a perfectionist, but certainly not in the class of Michaelangelo. 
The solar noon method of finding true north (by locating your tower's
shadow) is easier and more accurate than using Polaris.

BTW, solar noon is not very likely to be the same as noon on your
wristwatch  -- probably far from it.  For instance, my local solar noon
today is 12:56 PM PDT.  Find your local sunrise and sunset times and the
calculate the exact midpoint between them.  The sun only "moves" one
degree in four minutes, so you've even got room for a slight error if
you're not a staunch perfectionist, hi.
