The next bulkhead is sturdier, it will support the aft wing spar, the seat backs and the harness. I begin by cutting and fabricating some reinforcment bars and spacers, the all this gets backdrilled. Then all the harness anchors have to be installed. This is the picture when all is done.



I stumbled upon a problem because I had misread the plans about the drilling of the anchors. Here is a picture of the last one I installed and you may notice that bolts are not placed correctly, the one on the right is to near of the vertical part of the anchor and does not sit properly, all the assembly should be shifted slightly to the left. I'll order new parts for this.



I then cut some angle that I will then have smoothe and drill next time
