Some time ago I was browsing the Anti Splat Aero website and I saw a neat pair of high-grade stainless steel brackets that they've designed that add significant strength to the vertical stabiliser front attachment point. I liked the idea, so bought them.
The brackets are designed so that they can be fitted any time, but I figured it would be easiest done now, and drilled the necessary bolt holes with the assembly sitting on my workbench.
While here I also installed the rivets that hold the regular attach plate to the vertical stabiliser front spar. The pneumatic squeezer made short work of these.
These brackets will add significant strength to the vertical stabiliser
