    Hi,Just wanted to say a big thank you for posting this. I've now made one using your very helpful design information (largely included in the image annotations, for those who missed them.) I've not made it as pretty as you, and I've made some modifications relating to the materials I had around and some ideas I liked, but I'm pleased with the results.

That seems to be working great, too!Once again - many thanks! I'm sure it is going to get lots more use in the future.Ben
