Five years ago I put up a msg for the ultimate cyclone for my Festool vacuum. I still believe it's the best and if you have the time visit my new web site( I am new to this so its a little clunky). I have a couple of Festool improvements. I am getting close to posting a jig I built to make drawers using the domino 500. It makes them fast and very accurate. But the cyclone post is done and works extremely well. Woodknut.com it doesn't look right on a smart phone or old versions of window. Please check it out fellow obsessed Festool owners!
