As the instruction state 'assume the builder is experienced...' that is not me. When time came to install vert stab, I had/have trouble visualizing how a top fuse cover and Goop (n/a so Shoe Goo it is) on the 'foot' would be enough.. The pics show additional section of yardstick with bamboo skewers glued just off c/l. Appropriate flutes and 'side tabs' got poly and base got Shoe Goo. When cured it was installed over base yardstick with poly and the side tabs got Shoe Goo.
