To make this tube out of concrete, you need to make a mould using 2 cardboard tubes, one inside the other. The diameter of the inside tube should match the mould (100/100/80). The diameter of the outside tube must be approximately 6cm larger than the inside one in for the thickness of the tube to be 3cm. This will need to be 2 to 3cm shorter than the bell chamber in order to leave a space under the glass so that the smoke can circulate.
