Beggining of construction : making the rear spar of the horizontal stabilizer.
First step : sanding the reinforcing bars of the HS-603PP with 400 grit sandpaper, then the scotchbrite wheel, much faster.
Purpose: Polishing all traces & scratches on the bars.
Rounding sides for these two bars fit perfectly HS-603PP having put clecos to assemble.
Then rounding angles to the wheel then the scotchbrite wheel for polishing.
Trimming the sides of the HS-603PP lime for the top and grit sandpaper 400 or 500 on the sides. The idea is to feel touched when the finger is passed over the edge and visually not see the traces left by the machine tool home VANS nothing.
Purpose : Remove the microcracks caused the uprooting of the material during the cutting in the fabric. This prevents the formation of cracks due to the vibrations of the plane after a few flight hours.
Assembly of all elements with clecos, drilling holes forest size 30.
Be careful to pay attention to drill perpendicular holes and not move the drill (risk of ovalized holes on HS-603PP).
For my part I have done everything with the drill press.
Drilling and assembly brackets with the famous VA-146 to make the first 6 rivets.
I will do it later, I have not yet primer for this part.
Drilling fastener holes of HS-708, size of the holes 21 and extension 411 of the HS- 12 size.
Nothing complicated for the moment !
