I haven't been able to make this purchase for a long time, mainly because I found the price a bit high for a piece of plastic. My (endless) research has shown that DD performs very well, even better than even more expensive alternatives. In the end I pulled the trigger on the "frugal" do-it-yourself model and am very happy with the result. After painfully cleaning my clogged vacuum 2-3 times during each project, I was amazed at how well DD worked. I used the new unit for a few weeks on a project that involved hooking it up to my miter saw, router and grinder. Also cleaned the floor under the table saw. I had about 6 inches of dust and shavings in my DD bucket. When I opened the vacuum cleaner, there was practically nothing inside. Perhaps the faintest whiff of microdust. It works out. I bought 2 5 gallon brine buckets with a tight fitting lid and rubber gasket. For the base, I cut a piece of plywood big enough to hold a cucumber and my shop vacuum next to it. a brine bucket (no lid) and my shop vacuum (wheels removed) to the base. I bought a cheap moving truck from Harbor Freight, removed the wheels and placed them on my base. I installed DD on the lid of the 2nd bucket. I made a gasket out of caulk, but you can just buy a tube of liquid caulk from Wal-Muerto. Place the lid on the DD bucket and insert it into the bucket on the base unit. So it rises easily. if you need to reset it (put on a mask!). Connect the hoses, plug in the vacuum cleaner and Bob becomes your uncle. itchy plug (IT). You connect the SP to a power source and then connect your main tool and vacuum to the SP. When you turn on (and off) your main tool, SP automatically turns on (and off) the shop vacuum.
