Re: [Phys-L] electron microscope rehab

[Peter Schoch <pschoch@fandm.edu>]

Hello,

Well, we spent a long time today pulling the covers off and cleaning...

Neither myself or my colleague can find a vacuum attachment on the thing!
We did find a lot of asbestos covered wires with cracking insulation, dirt,
and some other things that don't exactly match the website model/image.
We're not sure if it was retrofitted or just an earlier model.  All-in-all,
though, I think we've come to the decision that John D's suggestion is
definitely best -- mine what we can, scrap the rest and build one from
scratch.  The asbestos alone is going to add to our HAZMAT pickup allotment.

Thanks again, everyone!

Peter
