Step 2: The Plan

Picture of The Plan
The new arbor had to be strong enough to support the four Lady Banks, but easy enough to be built in two days by various levels of carpentry skills.

The overall footprint of the 8 4x4 posts was 16'-6" x 23'-0".  The 16'-6" dimension was a pain since most lumber yards max out at 16' for dimensional lumber.  I was finally able to track down some 2x12x20' pine.  This meant I could have three double-beams going in the 16'-6" direction and run 2x6x12' joists in the other direction.  This seemed to be not only an easy plan, but also good looking.
