Time: 4 Hours
I was able to build up the substructure for the left half of the HS. This included match drilling all the connections.
Next up was to insert the middle rib, HS-405 and the forward rib, HS-404. These are then marked so that you can drill them using the skin as a guide. This went fast and wasn’t too hard. However I may have an issue with edge distance on the forward upper and lower flange on HS-405. I will consult with the pros tomorrow and see what they think.
