    Sorry to people that had problems with the images, In my defence I just wanted to upload the high resolution version with minimum effort without the forum software cutting them down to 1/4 their size.

    Agreed.

    Ew
    The black rings are survey points. The section is currently in their environment lab so so they can monitor and test its geometry over a range of temperatures. The alignment/straightness needs to be kept to better than 10 micron, so the beam they use is very important. In a room off to the side they have stored the two granite beams they have already tested.

    Nope not plastic.

    I'm going to be radical and suggest wood - insulator, impervious to magnetic fields, not liable to be stolen and taken to a scrappy.
    One company I worked for we had to make a structure that would not be affected by magnetic fields so I made a wooden frame. Weighed around 20 kg and I could stand in the middle of it's 3m length and it would only deflect 5 to 10mm. The research organisation we were working with threw a hissy fit though so I had to remake it in GRP. Increased the weight by 50% while reducing the strength.
    Mosquito fighter/ Bomber anyone?

    I'll go with wood too, but on a minor technical point wood is not impervious to mag fields. Maybe you meant wood does not affect magnetic fields?

    Nope not wood.

    Hint: Although CERN does not have a problem using exotic materials, you are almost sure to have a sample of this in your workshop.

    Yeah I don't really think so either lol
    I doesn't look like the shape you would use in concrete....... but I have a lot of that in my shed.
    But then there are some pretty special concretes around.

    After that my ideas head off into left field like "quartz" but unless its going to be getting very hot I cant seeing it being better than granite.(and in that size it would make my list of "exotic materials" anyway)

    p.s. can't a guy get a cup of coffee around here? lol

    Polystyrene, brass, swarf, broken centre drills, rubber. No, wait, it's made out of a Douglas shaper. Woo hoo. Any of the above Josh?
    All of these are in my work shop.
    On the phone so please insert smileys.

    Another hint... It's a material that's not often seen in that shape, but commonly found in workshops in various other shapes..
