Riiiight, so my new Imperial transport prows (funnily enough, they look suspiciously like space marine shoulder pads

) and the two old-style prows got shelved for the moment as I didn't feel like struggling with the way I had rigged them.
Instead, an Imperial Tanker is being born. I've got a bunch of progress pics I've not emailed to myself because I have to do them individually and it's a pain; I might post them later...
I used one shoulder pad, then backed it with a few matchsticks superglued together, giving me some more thickness to work with and shape the rear face. The underside was closed with more plastic. A metal+plastic spine was glued into place, skew, and was broken off in such a way that it couldn't be reattached. I made a new one from wood, and will attach it once the tank is in place.
A pen was sacrificed to make the tank, sealed at each end with plastic, four plastic strips glued on to make banding, and 6 pins glued to the side to make it look cool.
The bridge area gave me trouble, as I needed to make complex shapes and quite a lot of thickness. The plastic I use is becoming scarce so I tried to use Pringles lids.
The stuff is completely impervious to superglue. So instead, a ice-cream stick thing was used, cut carefully with a surgical scalpel (everything but the pins is getting this treatment) and sealed with superglue using my newfound knowledge of non-adhesive Pringles lids. The core of this section was thickened with two rectangles of a different ice-cream stick, and then came the question of engines. What do I use, what do I have? In the end, an old lolly stick and a cotton bud stick were cut up, giving a fairly nice engine effect.
Then more pins were added here there and everywhere:

This is the latest. Again sorry about the orientation, it is broken and the uploading thing I use doesn't let me change it afterwards.
More pins and plastic and all sorts to be added still. I'm debating small winglets, but not sure. The bridge proper still needs to be added, and I'm thinking a radio/radar mast fwd of it but before the spine. Possibly even a second gun turret could go just fore of that.
You can also see the fuel tank behind it.
