Dimpled all the Horizontal Stab parts and skins. Also trimmed covering back and sprayed with Zinc Chromate where the parts will come in contact with each other when assembled.

These pics are somewhat unusual.  Look close and don't go blind!

Began riveting the front spar assembly.

Now this was a fun job.  At least with the tools I had, bucking the 2 rivets that held the HS-404 was the only way.

Also the plans said to use AN470D4-6 for the HS-710 or 714 to702 and 405 but when I squeezed it

 it was too short so I got to drill out my first rivet and I installed -7's there but I did use the -5's to attach the HS-404.

This pic is after I installed the -7's.
