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.
