How to dust separator / collector w/ drum & blower

How to Dust separator / collector cheap, 55 gal drum and bounce house blower. Under $60 bucks! Sorry for the camera work, done by my 6 year old. Let me know if you have ideas on improving. Added a filter bag my wife made for me and that caught all the little stuff. **Update** Its been over 2 years and I haven't changed anything, except for adding a dust bag to the exit port. The dust collector is used for all my dust collection, jointer, planer, tablesaw, bandsaw, etc. Got a second blower and made a back yard bubble machine that fills the whole yard in seconds. Thanks for watching.
