I have ordered supplies from Wacuum Coatings i England. I was recommended Suprax-glas from a danish ATM, but that kind of glass was sold out, so I got a pyrex-glass. When I waiting for the supplies I make a working table and a grinding tool. The tool is made in concrete, have a diameter at 25 cm. and is 8 cm. high. At the picture you can see the tool and behind the tool I have some materials to a Foucault-tester.
