Kurt, Thanks for posting the pictures of the project. That tent enabled us to hunker down even in the worst weather and keep working; or at least leave the entire roof exposed at the end of the day without worry. So now, we have the whole system, not part, designed out: Masonry and roof venting, tent- allows unto take a look at the entire roof without the pressure of closing every night- (boat shrink wrap ROCKS!) Reinforcing the structure; adjust the insulation and mechanicals as needed. As always, I appreciate your invaluable advice and involvement on these projects. Marc, the gussets and brackets were engineered. The engineer checked the math on my design and fastener selection Btw, engineers are well meaning: its too bad you can't jamb 25 yrs of experience (i.e. dirt, grit, cut hands, hot sun, cold weather, heavy lifting, etc, etc ) into a 2 year course.... -Kelly
