Old Smokey

This is what happens when you have a husband who's a bit of a mad inventor in his spare time. Occasionally you come down to the kitchen first thing in the morning to find something like this on the notepad...

Then he has a lightbulb moment and tells you he's thought of a use for his old air compressor.

He starts bringing bits and bobs made of steel home from the tip. Pretty soon he's got a collection of rusting old relics lying about in a formation that suggests he has secret plans for them.
