We have been working on sorting out the design and calculations of the first set of LVL diagonal Rafters, namely, the two rafters that comes from the C Ridge, down to the corners of where the Front Extension starts. It is the first time we have tackled this type of diagonal Rafter and it is quite complicated with different angles coming into play from different directions. It is a case of making sure that we understand exactly what is going on and how the real world measurements we got, fit with the drawings on the computer and making adjustments etc.
Finally, today we have got to the point of having a pile of parts (polystyrene foam strips, plywood webbings, internal noggings and the LVL timber) all ready and prepared for assembling tomorrow. Everything is carefully being sanded and cleaned for maximum strength as these diagonal Rafters are going to be expected to be handling quite large loads, rather than the more normal straight rafters that just goes from top to bottom!
The whole LVL rafters, including the corner Posts that we built several months ago, will be glued and nailed together and fit nice and tight – We Hope!
