Thank you for the truly elegant Equatorial Sundial design - I like the way that by its' not being coloured you can appreciate the different forms so much more easily.

On a different subject, I'm intrigued by the bellows design. I'm certain that I saw a similar crease pattern to this on Tomorrow's World in the 60's or early 70's (I know; really prehistoric) when it was being proposed as an easily erected 3-dimensional form suitable for emergency housing after floods and things. So far as I can remember the material was going to be something like Tyvek. The form was not pulled round into a tube but had flat edges to go on the ground surface, so that it formed into a tunnel-like structure. I often wonder whether it underwent any more development than the ideas stage; it seemed a very elegant structural solution! A little bigger than the bellows design, though…

Thank you Rob

Danke auch, Max. Wir warten für Fruhling und Sonne!

I thought the stand piece (parts page 4) looked a bit odd - one of the dashed lines is missing!

Also, I've found it useful to reinforce the dial supports. I ended up using some corrugated card I had, but some thick (solid) card would have been easier to cut. I've stuck extra dial support sections to the inside of the reinforcements (partly for the look of it, partly as it's how I cut the card to fit!) - but I may decide to fit a 'cover', so it matches the dial backs...

Thanks for pointing that out Justin, I've uploaded the correct file to the Sundial page.
