I managed to make two of the barrels for the Hotchkiss cannon. They're a bit wobbly and what a rigmarole I had trying to get them into shape. I cut out some gold card and wrapped it around a thin screwdriver. This didn't work, so I made the card strips bigger, started to form it with a bigger piece of pipe then pushed it through a pen tube. To make it look rounder I pushed some dry spaghetti up it then sealed it with Sellotape. I also started to make the box they are inserted into.
My wife had to ask where the spaghetti was for tea!!! (There was just enough left.)
