Today, resuming where we left off from the very short morning’s work day yesterday (which was cutting the legs for corners IJ and LM and then measuring the distance from these legs up to the metal bracket at the point up on the I-Beam meets the K Ridge, which turned out to be 5860mm and 5855mm and only 10mm and 15mm off what the drawing indicated – not bad!!), we got on with the job of assembling all the bits and pieces (10 strips of the 423mm wide plywood webbing, 5 strips of the polystyrene foam strips, 4 LVL timber lengths, and a heap of noggings – some angled and some straight). We spent the morning preparing each of these bits with the correct angle slices (24.2° to be exact) for all the LBL timber pieces, the 8 strips of the plywood and 4 noggings. Then we sanded everything to clean up the surfaces for maximum gluing strength and finally adjusted the template to handle these 423mm wide rafters.
After lunch, we went into the task of vacuuming all these bits and pieces, putting each into the template, and as usual, gluing and nailing the webbing on each side, flipping the rafter over and doing the other side. All this repeated again for the second rafter and .. oh boy .. we finally finished quite late just before 7pm!
Beams-IJ-and-LM-Constructed
It is good that we got these two rafters done so they can dry and be ready for installing on Monday first thing (after we have sliced the bevel on the top end first!!) and then we can get on with doing the O Ridge “elbow” rafter and tackle the final section of the specialised roofing job!
