Hi all!!!
Update: Catapult and towers
I started first with building the PE cat per the instructions and adding a small pc of .040" round rod for the pipework on the inboard side of the catapult. Next came the towers...first job was to modify the kit part by adding a section of windows to the towers...I don't know why Trumpeter didn't mold these pcs with windows, referance photos and even the box art clearly show them. My plans only show an overhead view of the towers with the locations of the windows noted but no side view, so by looking at photos of NO I just winged it. Next I needed to figure out how to make the windows...both PE sets don't include these windows so I made some by useing the "bottoms" from the depth charge racks of the GMM PE set and formed them into a curve.
Now that the window panes were made I needed to figure out what to use to simulate the glass, while thinking about how to do this, I spotted the clear vacume formed packaging from the liquid cement I just bought, so I cut out a small strip and formed it into a curve the same way I make gun tubs, I then painted the PE and attached the clear plastic with CA.
