Would it work to attach the 2x10s to the sides of the 4x4 posts (so they'd form a rectangle around the top of the inner perimeter) rather than have them sit on top or replace the 2x4s between posts? Is that what you mean? Would doing it that way be significantly less strong than sitting them...
Hmm, I think I understand. When you say the two opposite ends should be 2"x6"s, do you mean I should add them perpendicular to the 2"x12"s? So they would run parallel to the 18' sides of the rectangle? Then for the additional 2"x6"s spaced 2' apart--should those be parallel to the 12' side...
Hi. I'm hoping to get advice on how to safely proceed with building roof supports.
My husband and I built an approximately 12' x 18' x 6' run using 4"x4"s spaced 6' apart. So, the 4"x4" posts form a rectangle that is 3 posts by 4 posts. They're buried 3' into the gound, if that's pertinent...
