Building a PVC DUST COLLECTION System - Part 1 of 2: Ducting

I decided I need a proper dust collection setup instead of dragging around a hose to each of my machines. I did a lot of research online and decided the most cost effective and easily configured ducting would be PVC sewer and drain pipe. I planned out my configuration and did the majority of the building, then I will go back and install all the blast gates, splitters and reducers, and connect everything to my machines. This is part one where I set up the majority of the ducting. Part two coming soon.
