Reddit mentions of Controlling Dust In The Workshop

I don't think it's a terrible idea, but you've reached the end of my knowledge, which really boils down to a couple things...
You want to limit duct length and corners. Use solid ducting for as long as you can, then use the corrugated stuff. Always use Y fittings instead of the T ones, use 45 instead of 90, etc.
Along with dust and chips, you're moving a lot of air. Think about where you're getting it and where you're dumping it. Think about how the room losing it is going to get it back, which includes any leaky window or door, etc. It also means you're potentially trading conditioned air for whatever is available. I know a guy that has a dust collector that filters his shop air faster than the filter box hanging from the ceiling because it moves so many more CFMs.
Read the opinions on ducting and static. There are plenty of people on both sides of the grounding issue.
I bought Controlling Dust in the Workshop, but I haven't finished it yet.
