Section 08 Horizontal Stabilizer

Section 8 Start: 15.02.2017, Section End: 05.06.2017

Began with the Horizontal Stabilizer (HS). Prepared some Stock (edge deburring, flange straightening) and created two sets of cradles for holding the both HS halfes alligned.

Page 8-1 to Page 8-5
Started again with prepairing the edges, lightning holes and the powder coated HS-912 hinge bracket. Fabricated the HS-1008L+R left and right front spar attachment brackets, which are very critical regarding the hole spacing. As I had a dent in the VS skin I now agressivly rounded out the nose ribs and had no dents to the outside of the skin this time.
Like in the plans I created the jigs for the horizontal stab skin to hold them upright positioned.

Nach dem Entgraten aller Teile des Höhenleitwerks folgt das Bohren der Löcher auf Maß. Jedes Bauteil erhält dadurch seine zugeordnete Position. Anschließend wird nach dem setzen der Bohrungen jedes Bauteil hierfür nummeriert! Dann wird die Baugruppe zerlegt um alle Bohrungen von beiden Seiten zu entgraten.

Section 10.1 ADAHRS installation

Avionics: Fabricating the ADAHRS bracket

I copied a method somebody showed on the Matronics List in the RV-10 tread. As I read in the Sky View installation manuel, you have to be sure to mount the ADAHRS somewhere as far away as possible from iron metal parts. Otherwise the internal compass in the ADAHRS could show wrong directions…
Now that I know that Van´s provide a ADAHRS-Bracket, I will order this vs. the DIY version. Much less work for me…

Section 09 Elevator

17.07. – 28.07.2017 9h

Prepared the parts for the elevator. Deburred all edges and holes. Clecoed all the sceleton parts together. Working on both right and left elevators. Frank is cutting the foam ribs for the trim rudder.

Sometimes I add a video, which I also post to Facebook or YouTube. Just for aviation interested people, who are following my project.
