How to make a Bee Vacuum for swarm collection.

I started this little project because we came into possession of an expanded polystyrene box and lid of a suitable size, about 60cm x 35cm x 25cm.
You will require such a box, with a close fitting lid and walls thick enough to allow fittings to be added, in this case about 3cm thick. A wooden box of a similar size would be fine and may be easier to work if you have some basic woodworking skills and tools.
