Completed tail section pattern templates

After a productive day, all the pattern template forms for the tail section assembly ribs are completed, and I got a head start on the rough shaping of the remaining curved shaping forms which are now able to be cut.

Drafted spar and flaperon ribs.

I researched options to harden shaping forms that will be used for multiple copies of parts. The Minwax wood hardener I saw a YouTuber recommend, is apparently a bad idea. The most common recommendation I'm finding for HDF is shellac cut by 50%.
