Cyclone build part 3 – the ‘Air Outlet’
Cyclone build part 3 – the ‘Air Outlet’
The ‘air outlet’ takes the clean air out from the centre of the cyclone’s ‘upper body’. It is a fairly straightforward tube 75mm in diameter, 154mm long, and made by rolling up some 0.75mm thick polycarbonate.
The centre diameter of a roll of parcel tape just happens to be exactly 75mm , so here I use it to check my air outlet tube. Like the cone It is made from a length of 0.75mm polycarbonate sheet. Notice the edes are cut so they gradate and distribute the jointing forces, so that it makes a nice circle. We can also work out which way the air would want to be spinning and let the inner edge complement that.
Incidentally, with a fine toothed blade the bandsaw is doing a fantastic job with this stuff, some of which is slightly too thick to be cut with the magic tin-snips.
Here is the cutting diagram for the cyclones air outlet tube, click for a larger version.
