Tonight I’m starting on another F1 Mod to the Horizontal Stabilizer. This mod calls for adding skin stiffener angles to the upper and lower skin surfaces between the rib bays – 2 per bay, both on the upper and lower surfaces. See the diagram below. I began by marking lines of the HS skins where […]
F1 Mod – Horizontal Stabilizer Rear Spar and Tip Rib Stiffener Angles
Today I fabricated some stiffener angles to use of the horizontal stabilizer rear spar and tip ribs. These are again similar to the angles added on the Rudder and Elevators. Here is a diagram of the angle locations: I started with a piece of angle and roughly marked some lines of where to start cutting […]
F1 Mod – Drilling Ribs HS-404 to HS-405
While reading other build log posts about this part of the Horizontal Stabilizer assembly there are a few different approaches to getting good results when drilling. This is critical because if you screw up and don’t drill something straight, not only will you ruin the rib, but also the forward spar. What is documented here […]
Horizontal Stabilizer – Skin Drilling
Today I started drilling the skins of the Horizontal Stabilizer (HS). The skin comes predrilled but the holes all need to be drilled out to the final size (#40). Also the forward spar, between the root rib (E-705) and main rib (E-708), is not drilled. The skin is pre-drilled in this area, but not the […]
