PT lower fuselage fairing
'I am working on building my lower fuselage fairing. I am using a set of borrower patterns. What I am still trying to figure out is the correct thickness of plywood for the station formers. The blueprints I have call for 1/8 ply.The structural repair manual states this as well.But the few samples I have seem to be made from ply up to 5/16. Is there a service bulletin I am not aware of to increase the thickness. Or possible they are built by individuals that would like a bit more robust structure.'

'The original bulkheads are very light weight and will not hold up over time.
Remember, the engineers did not have any thoughts of these birds being 60+
years old. I would go with the heavier plywood. Birch is stronger than
Mahogany, but it is heavier. I currently use metric ply. Has more plys per
inch.
