teekj, Sorry if I jumped, no offense intended or taken. I apologize. I hear you, this is not an easy topic and unbiased data is hard to come by. I started woodworking about 2 years ago and bought a PM 1300. Over time I don’t think it’s cutting it; fine dust all over. I switched to a Wynn filter and trashcan separator and it’s better, but my suction has taken a hit, so now I trap everything I suck up, but I don’t suck it all up. Before I sucked everything up, but spat back all the fine dust into the air. I’m a bit miffed I spent the nut on the PM when it really doesn’t do what it advertises (really filter out the dust to a 1 micron level at the CFM advertised). I’m skeptical many of the other systems can do what they say either. My Wife is a Doc (chest specialist) and I’m asthmatic, so we’re concerned. I’m planning on buying a cyclone this fall, so I’ve been researching. I find Bill’s story compelling. He’s offered his plan for free for anyone to build, see if you can get that from Oneida or PSI. He claims you need 5hp when the major vendors say you can do it with 2.5 to 3hp. Sounds too good to be true. I tend to believe him, although I can see why you might not. At this point I’m thinking I’ll go ClearVue and 6” metal duct in my small (1200ft2) basement shop (I can’t exhaust outdoors). Might be overkill, but I don’t want to risk my lungs. I can not fault anyone for making a different call; I think just about anything is better than nothing. Off to bed, so sorry if this doesn’t make as much sense as I think it does. -- John |
