ALIGNING AND SETTING THE SUPPORT POSTS
Here the posts have been aligned with string and
set in concrete. It took about a half a bag of concrete per post.
This can easily be mixed by hand in a wheel barrow. Figuring where
the posts should be set was a nightmare. The pier is offset from
middle, and its mere presence made it impossible to accurately measure
diagonally to check squareness. The old carpenters 3-4-5 rule helped,
as did a bit of luck!
