Laminated third layer to spar uppers. As the spar's getting thicker, it's reducing the number of clamps that I have that will fit. Fortunately, each successive lamination is shorter than the previous section so it reduces the number of clamps required. While the spar is drying, I cut out and laminated some of the doublers for the spar. Ten doublers in all. After the glue dries, I'll be able to quickly sand each of them to final required dimensions and cut out lightening holes. While the doublers were drying, I trimmed some of the spar material to prepare for the scarf joints and trimmed the second lamination on the second spar. It tapers from 20 mm thick to zero over 1174 mm. Almost a 60:1 slope. A bit of work with the band saw, then a power hand planer, then, my favourite, sanding!
