Ah ha! A working Archimedes screw model. I've mounted the screw inside a box then added a stand to hold the box at an angle.
At the top of the box I've added a hole to let the sugar fall out. As the handle is turned the sugar is transported up the screw and dropped out of the top.
I could make a tall one of these for delivering sugar to my coffee! (If I had sugar in my coffee, which I don't) Anyway, all looking rather good. Parts done, photos, download and instruction next.
I'm taking daughter #1 for an interview at Leeds University tomorrow so hopefully it'll be on the site and ready to download Wednesday or Thursday.
