The latest FWW had an article full of suggestions to improve dust collector performance including baffles and external cyclones. I couldn't help think that what they were really saying was the dust collectors we all buy (other than big bucks cyclone units) are ineffective, inefficient and/or poorly designed. I can't think of another tool in my shop that comes "out of the box" needing so many mods to do it's job (that doesn't count jigs - that's different I think). Other than Jet and their Vortex, do you think other manufacturers will offer some kind of improvements in the standard 1-2hp dust collector and if they do, does it have to cost $700? Or is $700 about right? I really don't know, I'm just asking. FYI, I have a JDS 1.5 hp and bought a canister for it. So I have about $500 into my DC. I tried the old Lee Valley trash can separator, but it took too much of a hit on air movement. Like so many tool purchases, I kind of wish I could go back in time on this one. 2h or more...
