Match-drilled the FWD top skin to the panel framework. Fit and drilled the F-721C/D attach angles to the panel and the FWD canopy decks.
| Remove every other cleco so we can match drill the FWD top skin. |
| FWD top skin is drilled to the FWD framework, including the parts that had no holes (FW, F-7103, attach angles). A word of advice on drilling the holes in the FW. Since this is stainless steel, I had the bright idea of using an old drill bit so I would not dull my current drill. That was a mistake. After the 4th wallowed-out hole in the top skin, I figured out that I wanted the sharpest drill bit that I could find. Ok, so I didn't get a new drill bit, but my current #40 drill bit was pretty new, and cut perfect holes. Don't be cheap, use a sharp drill bit here. |
| Now, to drill those holes in the FW for the center rib. |
| Make sure the bottom of the center rib is the same distance from the other ribs as the top of the center rib. Then, mark a line centered on the holes where the top skin attaches to the center rib. Now, mark the position of the holes to match the holes in the other ribs. |
| Hard to see here, but it looks like we done good. |
| Better picture from inside. Now, we just need to drill those holes to #30. |
| Did I mention that I sewed my first real seat cushion a few nights ago? I'm pretty happy with the results. See the Interior section for the details. |
| You cannot see it from this picture, but I have marked the position of the panel on the F-721A FWD canopy deck. When I remove the FWD top skin so I can fit the F-721C/D attach angles I'll know where the bottom of the panel needs to line up with the FWD canopy deck. I don't see how you could get in there with the top skin attached. |
| Here, I'm fitting the right F-721D attach angle. |
| Drill the F-721D and C attach angles to the F-721A FWD canopy deck (left side). |
| Left side looking from the right. |
| Now, we can drill the holes for the nutplates in F-721C/D. |
