Having receivd my longer rivets, a managed to rivet the two reinforcing bars on the main bulkhead. It took longer than expected as the first rivets where botched up, and those long rivets are a pain to drill out.
But the result look quite good as the picture shows, the nes rivet being the one out of alignment.

I finished riveting the forward part of the main bulkhead. Here is a picture with the aft part.



On the aft part I have four more rivets to install, unfortunately those that are with the kit are too short. I'll have some longer ones delivered shortly.

Began riveting the forward part of the main bulkhead, there are still some parts to be installed.

Today, I begun assembling the main bulkhead. I first assemble the control column supports and the control column.
I needed too long a time to find out how to arrange the washers to have free play of the controls.
Once all was solved, I couldn't resist putting my wooden grips on the sticks.



Then I decided to apply the latest Service Bulletin from Vans. The right seat stick has to bolted permanently on rather than being left removable. It's only a hole to drill, a bolt, a washer and nut to install.



The I riveted the aft part of the bulkhead, to align everything I use the spar bolts.

One hour to prime the main bulkhead's small parts. I then worked a bit on the control column installation.
