Hi, new here. Just completed my separator using the 2620 "Brute". I wanted to use it knowing full well that it will collapse in it's purchased form. I have lots of metal working skills and tools, so it was easy to reinforce the Brute. 2) 3" 16 ga. bands strategically placed inside produce the desired result. I picked up the Rubbermaid 4 wheel dollie that "twist-locks" to the Brute and trailer hitched it to my model 600 Industrial ShopVac. It drives nice, and this sucker sucks!. I followed Phil's separator design to the letter, and it is a sweet machine. Tip: Ridgid makes a 2 1/2" short hose that is just right between the separator and the vac. It is called the "tag-along hose" and is available at HD. The one thing left to do is send my "appreciation" donation to our administrator. Oh, and thanks Phil.
