Caps noted, Jon. I accidentally sucked up a paper towel that had one corner soaked in acetone 3 minutes before. Got away with it but it was sure a mad dash for the switch. I have wondered about the bucket-max, as that hump is well vented. Another, much older 5 gallon plastic wet-r-dry we have is built very similar, and its just as noisy. But its been run till the bucket was full of water, many hours non-stop in its history, and its currently sucking from the RO sander. That one is at least 25 years old. And sounding like the bearings are loosening up. One of these days I 'spose. I've considered making an even smaller centrifugal separator on a 3 lb coffee can for the bucket, but I tried it once and would have had to make a new lid, it sucked the usual plastic coffee can lid right into the can. A sandwich of 2 disks of 1/4" plywood would reinforce it enough I think to keep the lip from ripping off, but the scarcity of round tuit's has struck again. Sigh...
