Ok. Operation Cashew Jar was a success!
First off, I pulled a plastic cashew jar out of the recycle bin after noticing it might give me the shape of the clear glazing I need to replace the broken bit on the nose. I cut a rough coupon out of the curved section of the jar:
Next, I laid out a centerline across the curve and drilled the holes for the cannon which would serve as the alignment points. I was pleasantly surprised at how pliable this plastic was, enbabling me to bend it to more of a curve as needed without breaking the thing.
Next, I carefully measured the opening and laid out the shape onto tape that I stuck on the glazing to serve as cut lines. I purposely made it a bit big so I could file the edges down to fit tightly.
A lot of careful dry-fitting and trimming got me to this point. As you can see, I needed to bend the piece near the cannon holes even more.
Bending the curve tighter was easy. I forced it to bend around a paint brush handle cold and it stayed where I bent it. Then I cut a section from the straight part of the container and trimmed it down and bent it until everything dryfitted nicely to the model:
The joint line between the lower and upper section of glazing is exactly where the framing ends on the real 410, making this a convenient break point. Satisfied that everything fit nicely, I cleaned up the parts and dipped them in Future to set for a day or two before I glue them in permanently. The cannon holes will then be drilled out again to match perfectly.
I was pretty happy with this material. I think I'm going to hang onto this jar in case I need it again! Thanks for looking in and for your continued interest.
