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.

Again some work on the main bulkhead. First I primed the countersunk holes, then I riveted the nutplates and installed the bushings. Then, two sapcers have to be fabricated from aluminium tubing. I always cut them a bit long, then get them to the correct length by using the drill press and some abrasive paper.



Then I tried to install the control columns. I have some problems figuring out how all will have to work, it looks like the aileron bellcrank, but I think I'll have to adjust the parts to get it work correctly.
