how to fix an axle in an all moving stab
Hello,
I have an F-15 jet with an all moving which has not flown yet. while installing servo i put some torsion on the main axle and surprisingly it rotated inside the sleeve.... to fix the problem i used thin CA and coated the axle!!! Apparently, the axle seems to be holding on even when trying to rotate the axle, but needless to say i don't feel secure about the integrity of this fix.
i would like to avoid opening the bottom skin not knowing what to expect and how difficult it would be to remove the skin if it is well glued.
Any idea would be welcomed.

Cut a hole about 1/4” infront of and behind the pivot shaft on the root rib that faces the fuselage. This will allow you to look inside and see how well the anti-rotation setup is of the pivot shaft. You’ll also be able to get into the surface with a hysol nozzle in order to apply more glue if needed.
