To properly align and drill holes for the elevator joiner wire into the elevator halves, center the control linkage assemly on the stab and elevators. Trace the outline of the joiner wire onto the bottom surface of the elevator halves.
The slight forward sweep of the bolts is noticeable in these shots when you consider the position of the camera is forward of the stab, pointed to the rear. This sweep angle is necessary for servo travel
clearance against the fuselage's rear post, when up elevator is applied.
