More edge breaking and beburring - 6 hours

 This is actually a number of small sessions from Nov 1st through the 4th. Lots and lots of edge breaking and deburring. Super boring. 

 

Drilled remaining holes in the F-770 side skin - 2 hours

 Before I started to drill the pitot/wiring hole in the side skin. I noticed that the hole I made in the F-715 seat rib (using the tooling hole) does not line up with the pilot hole in the F-770 side skin. I did some research on this and looks like I am not the only one who has done this. (Wirejock has done it as well).I decided to use the hole i made in the seat rib as a guide and ignore the pilot hole in the side skin.

 

Next I drilled the holes for the fuel supply and fuel vent lines in the side skins. Once I was done that I started in on some edge braking and deburing.

Finished installing the nutplates in F-706 bulkhead - 2 hours

 Short build day today, been occupied with a million other things.

I finished installing all of the rivets in the F-706 bulkhead.

Prep'ing the fwd bottom skin and various pieces - 4 hours

I’ve been off the build for a while. My daughter Reed got very sick with appendicitis and was in the hospital for about a week. I stayed nearly the entire week there with her, so the build was on pause. She is all good now, so I am eager and motivated to get back to work. Lots of work was done today and little in the way of pictures to show all of it.

I started the day by deburring all of the holes in the F-772 forward bottom skin. 

Next, I started to work on enlarging all of the rudder cable holes in the F-902, F-724 bulkheads. Clecoing the ribs to a piece of MDF makes enlarging the holes really quick and easy. 

 

I also drilled the wiring/static holes in the F-724 bulkhead ribs.

 

 

 

 

Worked on the F-706 bulkhead - 3 hours

 I needed to spend some time working on the F-706 bulkhead. Lots of little items to do here. In particular I have to dimple a number of holes for #8 countersunk screws all because I have chose the removable baggage and floor panels. It's always stressful dimpling these holes as they are prone to cracking if you are not careful.

I followed the same method as usual. I debured, then used scotchbrite on the dremmel. Switched to #800 grit sandpaper and polished the hole with the dremmel. A little WD-40 and dimple. 

Once all the holes (and there are a lot of them). I drilled them for the nutplate, and then cleaned and spot primed.

Prep’ing the firewall and the aft fuse - 3 hours

 Managed to get to work on preparing the firewall. The powder coated weldments have taken a little abuse with the fitting of the forward fuse parts. So I de-burred, cleaned and primed the outward faces of the weldments.

 Next I started in on the aft fuse. I deburred all the new holes and cleaned them up. I then dimpled all the holes along the longeron and the new line of rivets where the center section attaches at bulkhead F-706. After dimpling I cleaned the area and primed both the inside face and the outside face. 

 

Finished countersinking fuse parts - 6 hours

Managed a good long day in the garage. I completed countersinking all of the fuselage parts. 

The bottom angle on the firewall.

I countersunk all of the forward fuselage stiffeners and floor stiffeners. 

I started deburring and dimpling some of the primed fuse parts I had like the F-623 corner ribs

I deburred and dimpled the arm rests. Broke the edges and cleaned them all up ready for primer.
