I was originally planning to have it filled with the square pattern seen at the ends. However, I changed my mind and decided to go with a sparser pattern. It should provide plenty of rigidity for this prototype.<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-130\" src=\"https:\/\/i0.wp.com\/thoughtfulconcepts.com\/blog\/wp-content\/uploads\/2017\/03\/20160926_194805-Medium-300x225.jpg?resize=300%2C225\" alt=\"Webs on interior of torsion box base\" width=\"300\" height=\"225\" srcset=\"https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/20160926_194805-Medium.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/20160926_194805-Medium.jpg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/20160926_194805-Medium.jpg?w=1024&amp;ssl=1 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>The glue-up was done in two stages, first to attach the sides and all the webs to the base, then to attach the top. Many clamps and weights were used to hold everything together while the glue dried.
