With the engineer's signature, the proof was completed with 61 pages of calculations.
The newly designed structure now channels the forces from the vertical stabilizer into the fuselage in a controlled manner. To achieve this, the wooden bulkhead is reinforced with a 3mm layer of carbon fabric, and the underlying structure has been further strengthened with an additional construction.
The carbon layer has now been applied with the specified fibre orientation, all holes have been drilled, and steel bushings have been inserted. For the existing bracket, additional tabs had to be welded on. However, this caused significant distortion, so I decided to manufacture an entirely new part from scratch.
The bracket is now securely screwed into position. However, it's still fastened with screws that don't meet the required specifications. The ordered screws still haven't arrived, even after 8 weeks of waiting, so construction cannot proceed any further for the time being.
Update:
The first batch of screws has arrived. While it's only half of the order, construction can continue.
Hardware valued at $754.
