Yesterday Dylan and I visited Tube Bending Ltd to talk about the double helix and materials.
Dave was really helpful and seemed confident that out idea was achievable. He said that aluminium was definately the most appropriate material to use beacuse it is so strong and light. The pipe only need to be and inch and a half diameter and it will still be plenty strong enough. This is great news because the thiner pipe will be cheaper. He also had a great idea for how to attach the individual pipes together.
The actual bending of the pipes is not very expensive so he said that they could bend them for free, only charging labour. He also said that they can source the pipes for us, only charging the cost price so they make no proffit. This would be good but we are going to pursue getting full sponsorship of the aluminium from a supplier.
He gave us an example to show everyone on Friday. We will explain further then.
Nicola and Dylan
