Tonight I’m continuing where I left off in my last work session. I’m working on the horizontal stabilizer rear spar to tip rib stiffener angles. I began by center punching and drilling pilot holes for the rivets. Once the angle had the pilot holes drilled, I clamped it in place so I could match drill the […]
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 – HS-3201 Forward Spar Doubler Drilling
Today I spent a lot of time drilling holes in the arms of the HS-3201 forward spar doubler. As mentioned before, this is a key place to be using a drill press for maximum accuracy. I don’t have a lot of discussion to add. I think the pictures here speak for themselves and my process. […]
F1 Mod – HS-810-1 Reinforcing Angle Tapering
If you recall way back in this post I replaced the Van’s HS-810-1 reinforcing angle with a larger piece of angle (same dimensions as the lower HS-814-1 angle) as part of the F1 Modifications. Tonight I worked to taper this new angle (this would be F1 Rocket part number HS-014). I started off by cutting […]
