Ok, I give up and need to get the Festool dust extractor. I converted a shop vac, but more Rube Goldburg than anything. I am trying to decided to get the dust deputy that sits on top of the dust extractor. It says it fits the CT models. Anyone using that. The midi is 3.9 gallons, the CT26 is 6.9 gallons. Is the midi big enough. Do I need bigger than the midi if i am getting the dust deputy? Or just add the 5 gallon bucket dust deputy and get the CT36 with the money. Anyone using the dust deputy made for Festoot or how are you mounting the dust deputy?
