More overhead console work

After clecoing the cabin cover and tailcone forward top skin back in place, we positioned the cabin cover against it (centering with the prior markings), then drilled a few shallow holes for clecos:

It became clear that the cabin cover itself needs to have some material removed for it to sit flush, so we only drilled 6 holes for now, and will do that adjustment once the cabin cover is off again and upside-down.

We then removed the console and the top tailcone bulkhead, marked the inner surface, and opened up the vent holes to line up with them (as well as the Aerosport controller):

Since there was some overlap between the bulkhead holes and the corrugation, I trimmed up the corrugation to the limit of the inside surface of the console, to get a little bit more air flow:

With this, I could finally prime that top bulkhead (along with parts from other sections):

It was then time to open up the overhead vent holes, which we did with a diamond cutter:

And last but not least, we match-drilled the cover plate holes into the console, for #4 screws (which Aerosport said should be more than enough), then attached nutplates to those holes (using CCR264CS3-2s):

While the cabin cover is in place, I'll work on the door fitting so that the cover only has to come off once more before it's attached for good.

Total cabin cover rivets: 52
Total cabin cover time: 66.3h

Door pin blocks

I started working on the door pin blocks, starting by positioning and match-drilling the stock blocks:

Van's forward pin block match-drilled into place

Van's aft pin block match-drilled into place

With those reference holes, I then started "sculpting" the Planearound blocks (which are larger) to fit tightly in the same spot:

Planearound pin block next to where it needs to fit

Forward Planearound pin block in place

Aft Planearound pin block in place

"Sculpted" Planearound door block to fit tightly in door opening

All four sculped Planearound blocks

I also started fitting the Plenaround third latch, and since I still have the door halves separate, I'm considering installing it before joining the halves, which avoids the large slots to insert it:

I also installed the nutplates inside the door handles:

I still need to make a final decision on how to install the Planearound system, and still need to actually fit the doors to the cabin cover and join their halves.

Access cover mods for oxygen fill valve and rudder pedals

I came up with a way to attach the oxygen fill valve to the seat back brace closetout, using a couple angles to center the gauge through one of the openings:

I also dimpled all the floor attachment holes on the ribs, in preparation for attaching the floors (but am still waiting for the 5" GripLockTies to attach conduits before I actually rivet them):

Dimpled floor holes

Once the rudder pedals were installed, I made the openings in the forward tunnel cover for their arms, and split it in two for ease of installation:

Rough markings for rudder pedal arm openings

That gave me a rough initial cut that then had to be significantly enlarged to give clearance around the pedal arms:

I then needed to make a splice between the two parts - I cut a piece of .040 slightly larger than F-1051G, and copied the hole pattern from that part:

Splice connecting two halves of the forward tunnel cover

After deburring and primer, I riveted it to the forward section, and also added a bit of edge protection so there's no chance of the brake lines rubbing against the metal on the forward opening:

Doors started

With the finish kit here, we got started on the doors (as someone on Facebook said, "oh joy, doors!"), starting with the rough edge trimming:

Door outer shell marked for trimming

Trimming door inner shell

Trimmed door outer shell

I then sanded part of the inner shells for the gas strut attach doublers, and match-drilled it:

I attached the door a first time just to see what I'm up against - there's definitely a lot of trimming to be done, and it's even possible I may have to build the bottom lip back up to reduce the gap:

Larger than expected gap on the bottom flange

I also got started with some of the door latch parts, trimming/deburring the handle levers to fit, and drilling/countersunking handle nutplate holes:

Handle levers trimmed to fit

Handles with nutplate holes

I started drilling the handle mechanism parts, except I'm planning to use the Aerosport low-profile handles, so I'm not doing anything with the stock Delrin block yet:

Match-drilled latch mechanism parts

Likewise, for the Aerosport handles, the tubes need to have a significant length trimmed, as they no longer protrude to attach to the outside handle:

Trimmed handles and handle slides for Aerosport handles

Next I'll start the heavy sanding work to get the doors to fit, and to get the inner and outer shells joined. I'm also seriously considering building most of the latch mechanism while the door halves are still separated, since that seems to be significantly easier.
