Hi Simon,
I'll look at putting a marker on the map, for now I'm registering with the forum.
I have sourced acrylic sheets, Al u-shaped bars, Al right angled bars, PTFE for the strips, threaded rods and the u-bracket so far, mostly locally plus eBay UK.
I am still considering the plumbing pipe and may just use copper pipe, or a wood base and what? upright for the cartesian 'bot. I'll have to see if the Cu pipe will support the weight and the screwthreads in its walls.
When you get to this stage, let me know and I'll itemise the shopping list for Manchester! Cost £87 (Apr 09)
How much does the electronics part cost?
Nice to meet you!
Hazel.
