7mm Cringle Street Goods shed guttering.

 I used some half round plastic about 3.5mm diameter for the gutters, The ends had plasticard glued on and when set shapedwith a file.

The downpipe had a piece of twin and earth cable copper threaded into hollow tube and bent to shape- the end was left proud of the tube and a hole drilled in the gutter to locate and provide a mechanical connection.

Thin strips of brass were formed to mirror the shape of the gutter and used to fit in place.
