After a several year hiatus wherein the beginning of my project, building the tail feathers, was pulled out of storage so I could complete the rudder, I discovered I made a mistake on the original build... the angle at the top was incorrect due to me not having the space to lay out the full tail feathers side by side. Big sigh, but I hit reset and redrew on the craft paper covering my new workbench and stripped down the incorrect pieces in anticipation of the reset. Lots of sanding off of gussets and the like.
