I used a few gates to close off equipment not in use and kinda made up the rest.
I bought mine in parts and built it into a wooden box and bought a book about dust collectors after a couple weeks reading I was no smarter, so I got quotes from pros to set it up. One guy came in and looked at the collecter and did his thinking outloud and said 7" inlet 49", two 5 pipes at sander 50" close enough. With that I had enough information to set it up myself, I ended up with about 10 pick ups but everything had to be closed when the big sander was in use. You can adapt down to use with small sanders and saws but step it up to about 2" hose asap
