Battlecruiser, HMS Queen Mary

I attacked this problem by first making a paper tracing to use as a template for the new supported deck







Then the offending (to my eye!) solid resin area was ground away with a motor tool, taking care not to penetrate the hull sides or to go too deep-- a drum shaped grind stone was essential for this operation.
The outer 'walls' were lined with Evergreen strip, painted, and thereafter it was time to view the fruits of my labors by applying the new paper deck! Once glued in place, with the CA glue fully cured, the excess was trimmed off, and sanded flat with very fine sandpaper, as the CA glue lifts the grain of the paper very slightly.
The higher level aft was created using more paper and the stairway apertures onto both sides of the quarterdeck were cut through also, at this stage.




Stairway well was cut in, tackle boxes and other detail added...
