Should never take to much time off when working on a project. Glueing up the front side of the center spar. Both upper and lower cords done, have the upper cord reinforcement done so starting with the upper. Glued the cord on then realized that I had glued the bottom cord in place not the top. Three choices at this point, pull the cord and clean everything up as best in can, leave the reinforcement off and scrape all the dried glue off or make the bottom reinforcement before the glue sets. Elected number three, never made anything so fast when working on airplanes, done in under 15 minutes, the pieces is 82 inches long. Decided last night to glue the top cord on and not do the reinforcement until later. Very careful with the glue won’t require much clean up.
