Perched on the back of the British Swiftsure class submarine, HMS Spartan, is the English equivalent of the US Navy SEAL's Dry Deck Shelter. I'm no expert on British Special Operations Forces (Special Boat Service?), or what they have done, but this looked pretty cool so I had to have a go at it.
This is intended to be used with Airfix's HMS Trafalgar kit. The HMS Spartan was a Swiftsure class boat, and the Airfix Trafalgar can easily be converted into a Swiftsure. It requires removing 7 mm of hull length aft of the sail, lopping off 2.5 mm from the top of the upper rudder, and replacing the Trafalgar's single hull side vent with a double set (that's provided in my conversion kit). See here
for a how-to guide if you're uncertain.
The hinge for the door on the HMS Spartan DDS can be made to work, but takes some care to execute. The hinge pins will require .31 mm diameter steel piano wire. Holes for the hinge pins are printed but will need to be carefully
opened up to clean out the support material. I used a .3 mm diameter drill and ran that through first by hand (bascially I held the drill as tight as I could in my hand and carefully rotated the door around the drill to open up each hole). I then followed that with a .35 mm diameter drill bit. Let me stress care must be taken, so ensure you're 90 degrees to the surface, let the drill feed in, and don't get distracted because one wrong move and you'll will snap the hinge arm on either the door or the DDS. Like I mentioned, the pins are .31 mm diameter and only a few mms in length. As its pretty difficult to accurately cut the piano wire at these small dimensions, I cut what looked right and ran with it (half of the ones I cut pinged somewhere around the room), using tweezers to feed into the holes and secure the door. But here's what you can end up with; working door hinge (see video below).
