Are there any pictures or post in the forum on how to attach the smooth edge surface section stern planes to the fiberglass hull for the Scale Shipyard 1:72 Skipjack?
thanks

Your problem is how to affix a stabilizer, sail, or other appendage to the hull and to do so in a manner that will afford reasonable resistance to shear forces.

One I favor is to first butt glue the appendage to the hull, drill holes through the appendage and hull, insert carbon rod or brass rod, slather on thin formula CA, then putty over the holes



Here I've slit that big tear-drop shaped towed array fairing atop this SIERRA-2 upper vertical stabilizer to accept G-10 spars. the gaps between resin and G-10 will receive CA and will be finished with putties and elbow-grease. Nothing short of an act-of-God is going to break that egg!





The two end-pieces of the horizontal stabilizers were tack-glued on, then slit, and G-10 spars slipped in and CA'ed in place.



The two anhedral pieces were cast with tabs at their roots. (The tabs are useless unless during the casting process reinforcing glass or carbon fiber was introduced to increase their shear strength). You slit the hull, slide the part in place and secure at the root and from the inside of the hull with thin formula CA.





As Bob Martin today suggested, make use of the stern plane operating shaft holes in the hull and horizontal stabilizer bearings to run a length of suitable diameter rod -- turning the rod into an alignment jig to guide you as you secure the horizontal stabilizers to the hulls stern.
