Never thought it would take me 8 hours for doing this bulkhead but it requires precision and there are a lot of small details that required many checks. As Van said , mesure twice cut once .... But over all, I was please of the result as it appears to be exactly as it suppose. Soon, I will disassemble all the bulheads clean, debur, dimple when required, spray the corrosion protection and rivet it all together. Once this complete, I will store away my wings and install the mounting fuselage bed.
