After moving all the large objects around out of the way and clearing and cleaning my bench I turned to assembling the baggage back per SD75-FR-06.
At this point I have largely given up on using the IPL file descriptions but I do check them for sequence, just in case, and additional direction. I am largely relying on the drawings and the EASM Solidworks files.
I had primed the back side (aft facing) of the SD75F-2 baggage back but not the cabin side which has the two LS75F6-5 overlaying so I cut some brown paper out and primed the cabin facing side of the baggage back where appropriate. I will eventually paint the whole inside of the cabin and other baggage area so I did not bother to prime the whole cabin facing side at this time.
The drawings on page SD75-FR-06 call for A5 rivets throughout the length of SD75F6-5 and SD75F32-2, all of which arrived as A4 in my kit, with the exception of the rivet holes that match the SD75F32-1 baggage back gussets.
The SD75F32-3 angles are all identical, drilled A4 except for a single hole that aligns with the location of the SD75F30-4 gusset on page SD75-FR-08, which is drilled A5. However, the centre bracket location on the baggage back skin is drilled A4 so it is necessary to drill out that hole in the skin to match the A5 hole in the angle.
One other issue is that my SD75F32-3 brackets were not labeled -3 but simply SD75F32, although that may have been my fault as I removed the labels and primed the angles and wrote the part designation onto the part so I may have just left the -3 off by mistake. I have been known to make one every now and then.
The pics below are of the assembly process. It’s important to not rivet the holes common to the SD75F32-3 angle brackets and the SD75F30-4 gussets and also to leave the bottom row of rivets on the SD75F32-1 gussets, per the drawings. Being extra cautious, I also did not rivet any A5 holes through the gusset and into the side channels below that last full row of rivets that go through the SD75F32-2.
