Bee vac video
A couple of weeks ago, I saw a bee-vac made using two nested 5-gallon buckets. The guy drilled 4, 1-½" holes at the same location 90º apart through both buckets, glued screenwire to the inside of the interior bucket. He used a bucket-top vacuum with a piece of foam in the inlet neck and used a piece of clear smooth hose instead of a corrugated hose. The vacuum pressure was regulated by rotating the buckets to control the aperture size created by the two overlapping holes of the inner and outer bucket.
I cannot locate that video anywhere. None of the youtube videos is the right one. Does this ring a bell with anyone?
Banjos and bees... how sweet it is!
