Installing the F-782C center cabin cover - 4 hours

 I am now ready to fit the F-782C center cabin cover. This is not a quick process as there isn't great information on the drawings of where exactly to place the cabin cover. Its a bit of guesswork where it fits front to back. Height is 15/16" to the top of the cover...but getting that height set requires a recipe of wood shims.

It takes some time to get everything placed correctly. Once I have the wood shims putting the center cover at the correct height, I can now figure out the correct front-to-back placement. Everything will be predicated off of the F-983C fuel valve cover. 

I could move the center cover back and forth until the joint with the Fuel Valve cover sits nice and straight...no bow.

Now that I have the front-to-back placement of the cover figured out. I can now start setting the location of the screw mounting holes in the floor angles

I used a piece of scrap angle with the #19 hole (for a #8 screw) at the correct height. Using that drilling template... I then drill all 4 holes in the floor angles. Using the 90deg pneumatic drill for this is a life-saver. 

Once the holes are drilled, I placed the center cover and used a sharpie to check the hole placement in the sides of the cover. Looks ok. 

I re-installed the cover. Double checked for proper height and alignment and then drilled the 4 holes for the future #8 screws.
