Model Jet Engine used for creating mold
from the movie Team America: World Police
(Paramount Pictures, 2004)
This is pretty cool: It's the original hand-made model of the 'full-scale' jet engines used on several of the Team America vehicles. These engines pop out of a hidden compartment on both the Lamborghini Limousine and the Team America Hummer. To make these, an original model was fabricated from what looks like large PVC pipe, wood, a paint can lid and some other items I haven't identified. Once it was finished (as seen below), it was used to cast a rubber mold that could be used to make resin copies (much easier than trying to build 6 or more of these things). If you look closely, you can see what looks like little white flecks stuck between the black PVC pipe and the brown wood/cardboard section. These flecks are little peices of the rubber mold material that stuck to the model when it was cast.
This is a kind of 'complicated' mold, so it was made in pieces. The
'turbine' section comes out and was made into a seperate mold by itself.
Now there's less angled surfaces inside the turbine area on the larger
piece, which makes the mold creation a little easier. I'm assuming
this was a 3-piece mold for this part.
Here's the back side of the model. You can see a line all the way
around it that represents where the two halves of the mold would come
together. Also, to further prove this is the original model, the large
groves that have been routed into the side all the way around the
engine are unique (each one has a little extra nick, scratch or roughness
to it). I have two of the screen-used engines in my full-size Hummer
body, and I was able to match these imperfections exactly to this
model on both engines. I know of six of these for sure (my two, two
more in another Hummer and the two used in the Limousine).
Here's some screen caps of these engines from the movie, you can
