| Extending Hole Pattern for Upper Subpanel Support | |
|
My first design used a piece of .032 angle the same width as the opening. I wasn't happy with the degree of stabilization this provided to the cutout in the subpanel. It seemed to allow for stresses to occur in the corners. I decided to extend this upper truss piece about 2" on either side of the opening. I used a rivet fan, clecoed to the earlier holes to extend the rivet spacing and rivet line to match the wider truss piece. |
