Wriggly tin, skylights, and smoke vents

It may only be a shed roof, but it has proved to be surprisingly fiddly!

The roof itself is 40-thou black plasticard on four triangular profiles, and is removable. The corrugated iron is Slaters, cut into strips and the upper piece has a 5-thou strip under the bottom edge, which provides just enough relief to represent the overlap.

However a comment on the NGRM forum about skylights made me think that it would look more interesting with some, and they would let more light in to show the interior, plus many of the prototypes I had looked at did indeed have skylights. These were made up from various sizes of microstrip, sitting just proud of the roof, and will have clear plastic slotted in from behind. In addition an engine shed needs a means of venting the smoke and steam - either a full-length vented clerestory or chimneys over ducting were the usual methods. I opted for the latter - because they looked simpler to make - using square section plastic.

The addition of Plasticard strip barge-boards and a rod along the ridge line tidy up the edges, it just remains to find some tissue paper to make the lead flashing and finish the roof. That still leaves the doors and a floor before painting, I think on this building guttering would have been an option that may have been omitted!

I've been on the lookout for items to detail the interior with, and when passing Gaugemaster recently I picked up this pack. I may not use all the parts in this model for fear of over-equipping a small shed, but it should give me a head start.
