Cabin top stiffeners

In this life, there is nothing more challenging and unrewarding than laminating the cabin top roof stiffener in the overhead position.  Unless of course..............

it is laminating the roof top stiffener of the other cabin.  One of the tricks that brings this into the realm of do-ability is using a sheet of plastic to wet out your reinforcement before you try to bond the whole mass onto the ceiling.  Another trick was using a bit of unidirectional carbon fiber in the mix to delineate the location of the unidirectional glass within the layers.
