    Default Dust, cyclone & Pentz comments from blog

    This is from a blog post on Lumberjocks and is a comment by Bill Pentz about commercial cyclones and dust collection in general. It certainly had me wondering (again) how bad my working area is. May help (scare?!) people...

    wanted to share some comments Bill Pentz had for me when I asked him about my new 2 HP cyclone purchase. So…here goes…by the way, Bill spends hours a day answering emails, like 7 hours a day. I hope that you would take the time and read the information he has on his web site (http://www.billpentz.com/woodworking/cyclone/Index.cfm) and the comments below before you would write to him. I pretty much asked him the plain facts, so this should take care of any discussion questions you may want to ask him. Also, I put his recommendations for my other four questions at the bottom along with the question I asked. (By the way, if I did what he wanted me to do in the first sentence, I would be closing my shop because my wife would kill me after I just bought this thing and set it up!) Enjoy. Todd

    In short, send that cyclone back and either buy or build a cyclone of my design and equip it to blow outside during nice weather and into a pair of the Wynn 300 square foot filters during bad weather...

    [rest is here]
    Shudder.

    Scary stuff. I started coughing just reading about it...

    I have my hobbyist 2hp DC outside the workshop, but I do get some air return. I think I'm going to gasket that puppy away from the shop somehow so that none of it comes back...
