I’m am sure some of you have built one of these and I am for CERTAIN everyone’s looks better than mine but it does a really good job catching floating dust that my Ricon dust system misses. Also this white elephant is on wheels and I can move near whatever I’m working on. The box is plywood and it uses up to 4 furnace filters. I got the furnace blower free for the asking from a local heating and air conditioning co. Thought I would post it and maybe give some new woodworkers an idea that would help keep their lungs and shop cleaner. Again I apologize for appearance but it really does a good job. I have a second blower and I am building another one and I promise it will look much better than this one. Thank you for looking.
