Baggage door complete

We finally removed the cabin cover for the last time, which allowed me to finish riveting the door hinge frame, and the left baggage cover:

Door hinge frame fully riveted (yes, I used CherryMax, don't judge me :) )

Left baggage cover riveted in place

With this, section 34 is 100% complete.

Time lapse:


Total baggage door rivets: 196
Total baggage door time: 15.6h

Baggage door mostly completed

With the baggage floors riveted on, I moved to the next section, riveted the door hinge frame, and attached the door (using the split pin mod that others have also used):

The only thing left on this section is to attach the left baggage cover, which I'll do later along with the section 35 panels.

Time lapse: 


Total baggage door rivets: 173
Total baggage door time: 14.3h

I riveted the door frames and bracket to the skin, which required supporting it properly, but gave good results:

Finding the right lock was a small quest - Van's only sells one along with an ignition switch, which I don't need, and I wanted something as flush as possible. I initially tried to find KABA-style cam locks, but finding one with the right size (5/8"-3/4" diameter, 5/8" length) proved to be just impossible. I ended up getting a few different ones from Amazon and mixing their parts - I used the cylinder from this one, the cam (bar) from this one, and the locking washer from this one (after flattening its "claws" and then introducing a slight curvature):

With this in place, I riveted the inside close-out panel:

Next is actually attaching the door, after the floors are riveted in.

Started painting fuselage interior parts

After the primer batch, I decided to paint the primed interior parts that would be visible:

Painted baggage door, baggage area and rear seat parts

Painted baggage door and tailcone attachment parts


Painted floors and rear seat backs

Painted cover plates

There are aparts already attached to the fuselage that may also need painting, plus most section 35 parts are not finished/ready for paint yet, but I'll do those later.

Overall, painting with the spray can was just sooo much easier than the HVLP, and I was pretty happy with the results.

Time lapse:



Total paint time: 1.5h
(but I'll count the total time in each section for the parts, proportionally)

Large batch of fuselage primer

We primed quite a few parts from various fuselage sections (and even some from the empennage attachment, and for rebuilding part of the vertical stabilizer):

Primed fuselage parts on the floor (ran out of space elsewhere)

This unblocks a ton of work, so expect many more posts in the near future.

Time lapse:


Total time: 6.5h (but I'll count it towards each section instead)

Baggage door started

I've been working on the baggage door slowly, whenever there's nothing else to work on.

This section is mostly straight forward - cleco everything together and final-drill:

Main door parts clecoed together and final-drilled
then the tricky part, which is making the hinge and drilling it on both sides such that the door is actually flush to the rest of the skin:

Marking the hinge holes for the door side

I also used the common deviation from plans that involves cutting half the hinge eyes so that pins can be inserted from the center, allowing the whole hinge to be closer to flush with the skins:

Making the door hinge almost flush with the skin

Finally, the recommended method to drill the other half of the hinge to the fuselage involves modifying clecos so they fit inbetween the halves:

then centering the door and match-drilling from the inside:

which, of course, went very wrong:

Accidental double hole when drilling the fuselage side of the door hinge :/
so I did the whole hinge over from the start, just reusing the door side holes and match-drilling the door to the hinge rather than the other way around. This time I was a lot more patient and careful in drilling the hinge frame into the hinge, so it went fine, and I countersunk the hinge:

The next steps are just deburring, primer and riveting.

I was also considering adding a baggage door sensor (microswitch or similar), but given how hard that'll be, it's probably not worth it.
