I came up with a fix based on the reference photos above to secure the torpedo to its fairing. I used some thin gauge wire and tiny thin squares of evergreen styrene with holes drilled in the center to give the wire something to hold on to. Glued the squares to the pylon and inserted the wire held in place with my favorite styrene friendly super glue, "Plastic Surgery". Whew! I might go back and add a little more detail
later because the more I stare at it...
While I'm at it, I want to mention the wheels supplied in the kit are sagged tires. It's my understanding that carrier planes had their tires pumped up to the max to counter act rough deck landings. It would have been nice for GWH to supply both tire options like others do. I used them anyway. I was going to steal the pumped up wheels from my Monogram kit but they appear to be incorrect for this TBD version and don't fit the gear anyway with out some slight modification.
George: Thanks for the tip on the Tamiya blades. I will give those a try. I am testing Vallejo's Metal Aluminum out at the moment. I'll let you know what I think. I usually go with Alclad.
Andrew H: The Iwata HP-CS is exactly what I was thinking of purchasing. do you have the model with the cup on top?
