Today I began working on the bulkheads, beginning from the back. The two aft bulkheads will also support the empennage, some holes get only drilled at the empennage fitting stage so one has to carefully study the plans.
Here is the most aft bulkhead, it allows also to fit a tie-down ring. The tie-down support has to be cut, drilled (but not all the holes some will get drilled during empennage fitting), and the tie-down hole has to tapped.



For the next bulkhead, two bars and an angle need to be cut and back drilled. On the bars you can the the lines along wich I could cut them to save some weight. I think I'll leave them as they are, the cuts are quite long to make and I would risk messing up something.



For the next bulkhead, again an angle to cut and drill. The two big holes are drilled, they will allow passage of the rudder control cables.



The last bulkhead is the easiest, only deburring and fluting to do. Those two operations have also been done on all the parts fabricated today.
