Today, I worked on the main bulkhead. First I backdrilled into position the four rib supports on the forward side. As there are some nutplates ont the bulkhead, I countersunk the rivet holes.
There are also nutplates on the supports, and on the two stiffeners I made out of some aluminium angle.
There is some interference on some of teh bushing. My solution was to carefully saw a slit in the bushing and then install the interfering part.
Then I installed the angles that will support the control column on the backside of the bulkhead.
The I cut the optionnal lightening cut, here is the result.
I finished the session by deburring all the parts.
