The cyclone is sitting on an expanded polystyrene disk on the paint can
lid that has another expanded polystyrene disk under it and is just
screwed together. FWIW sometimes I forget to seat the lid firmly but
then the suction keeps the lid on and no special care is needed to seal
it until I turn the shopvac of.

The reason for the lashup is that many materials are hard to come by in
