Here's a spreadsheet I'm putting together to record all the exact sizes. From these sizes, I will be able to work out how much each cylinder will weigh. I'll pass this information on to the Architects and Builders involved in the project so that they can build a bar on the interior wall for the cylinders to hang from. The weights will make sure that the bar is strong and secure enough to hold the weights of the cylinders.
Here are some CAD (Computer Aided Design) visualisations drawn for me by Dave Weaver, who works in one of the other studios at Centrespace, where I'm based in Bristol. I've been working with Dave to come up with a structure to hold the metal cylinders together.
