Cut notch-outs on for horizontal stabilizer bolt access.
Positioned horizontal stabilizer to forward limit, clamped and drilled 1/4" holes and bolted horizontal stabilizer in final position.
Ground powder coating and very slight amount of material from elevator horn control arm tip to achieve the full 160 degree reference angle for elevator up deflection.
From this point I started attaching the vertical stabilizer to check clearances when installing the vertical stabilizer when the horizontal stabilizer is bolted down and cannot be moved aft while just clamped in position.
