The butt ribs are now fitted. Contrary to the manual, and by recommendation from other builders, I swapped sides on the butt ribs. The reason is to put the wider part of the cap strip to the inside. By doing this the holes drilled in the acrylic windshield are further from the edge so less chance of cracking.The next part of the build is to give the butt ribs, #1 rib and #3 ribs at lease two coats of epoxy varnish. The butt ribs will be permanently attached later. Next task is to fit the jury struts.
