Interesting video KWC. You guys brought up some valid points about the test most notably the blade in the Bosch. Also, he used a shop vac on some of the machines. The Midi on others. Throughout the test he used the 27mm hose on the midi. First off....I have two of those hoses. They work great on my TS55REQ and my Carvex. It's total crap on my Kapex. May as well not use a hose (well not true but not efficient at all). I bought a Bosch 35mm hose and an anti static 50mm hose. Those collect the large volumes of dust the Kapex makes and I might add on my DW745 saw too. Additionally, a shop vac ain't a DC. Totally different, it doesn't collect that dust. It collects the large stuff as some of you guys mentioned and that would affect the test. The Bosch and Festool hoses both work on my midi and you guys are correct, a simple adapter would have yielded different results. Regardless of the hose size you could at least make a more consistent result although the larger diameter hoses on the saws work better. Also the blade on the Bosch was an issue. I read a post on the FOG, and this is of interest to you Madman (and anyone else that has the Axial) one of the members added the Kapex dust shroud to the Bosch drastically improving its DC.
