They look fab James.

I think I've worked it out now. I shall get the Bonny Doon gizmo which I shall use with strips cut to the correct width (by Cooksons) and then cut them down. I shall then bind them together over a former and solder them together.

My problem is that everything I make has to be also made by a team of people who are not master jewellers (neither am I!). They also have to be reasonably priced. I potentially will need to make hundreds of the damn things. One of my team does make very tiny silver boxes and box rings, so I may get him on the case. I wish I could pull out, but I'm committed now.
