This was actually over two days
There are two l-angles on each side of the baggage compartment that attach the baggage floor to the upright and flaperon control cover. These go in the corner and basically stop the whole thing from sagging at the ends. So I raided the l-angle stock one more time and cut some pieces to size and then removed the upright and flaperon control covers. Each has the holes predrilled so that made drilling easy. Here’s the one on the flaperon control cover.

and the upright.

Note that the l-angle on the flaperon control cover needed to be trimmed. I put these back into the fuselage and made some marks on the baggage floor where the l-angle rested, will drill those holes later when everything is out of the plane.
From here, it was a quick and easy assembly of components. The right control tunnel side goes on

and the left control tunnel side

The control tunnel top

Next up were the lower right and left baggage floors but they are impossible to get in with all the other stuff on, so I had to take them out…. sometimes I wonder about the photo manuals, why didn’t they put these in earlier? Here they are, with the control tunnel pieces reassembled

With everything in place there are two triangular gussets that go under the lower baggage floor and attach the torque bearing channel to the side skin. I clecoed these in place and with my 12″ drill bits drilled the other holes and enlarged them. There seems to be no pictures of that. Ah well, on with more drilling, enlarging every hole to size 30.

That pretty much completes assembly of the baggage compartment with the exception of a couple of things to do outside the fuselage. One of these was riveting the l-angles to the baggage floor.

and then I drilled and riveted the l-angles that I made at the start of the day. It will be impossible to do those inside the fuselage.

Each lower baggage floor gets two l-angle stiffeners so I cut and drilled two pairs to fit

The rear l-angle overlaps the centre hole that is shared with the torque bearing channel so I put that back into the fuselage and trial fitted the baggage floors.

In order for this to work I had to cut a notch out of the l-angle so it would sit on top of the channel. Here’s a view from underneath.

And that is it for the baggage compartment. After this I deburred all of the pieces and set them aside for later.
