The project starts with the Horizontal Stabilizer. The skeleton is made up of two spars a forward spar and a rear spar connected together with three ribs on each side. The forward spar is bent at an angle and spliced with two splice angles. The skeleton is covered by two skins that are pre-cut and bent at the factory.
Recieved, inventoried, organized and stored the empennage kit.
Drilled the holes on the web of the rear spar. Started on the rear spar stiffeners.
Finished drilling & deburring the stiffeners on the HS rear spar. Drilled and deburred the elevator hinge brackets. Riveted the bearing to the center elevator hinge bracket. I will have to wait to finish the rear spar until I find some primer.
Fabricate HS-610 and HS-614 forward spar splice angles.
Trimmed the HS-602 forward spar channels, lined them up on the jig with the HS-610 and HS-614 splice angles and drilled the rivet holes.
Did some more trimming on HS-602 (front spar) and deburred it. See note.
Bent the front spar and front spar splice angles. Started deburring ribs.
Deburred and fluted ribs.
Cleaned, etched and primed all the parts of the HS rear spar.
Riveted the rear spar together.
Worked on building brackets to fasten the rear spar to the jig.
Mounted the rear spar in the jig and started building up the HS skeleton.
Finished drilling all the parts of the HS skeleton, un-clecoed the skeleton and started deburring all the parts in preparation for priming.
Finished deburring, cleaning and treating all the HS skeleton parts.
Primed all the HS skeleton parts
Started assembling the HS skeleton
Finished the HS skeleton and drilled and clecoed the skins to the skeleton.
Deburring, dimpling HS skeleton and skins.
Built a make-shift table for the C-frame tool, finished dimpling the skins.
Sanded cleaned and treated the HS skins.
Primed the HS skins.
Started riveting the skins to the skeleton.
Finished riveting the skins on the HS skeleton. The horizontal stabilizer is finished
