I haven't ran all the piping around the room yet, since the tool stations aren't permanent yet, though.

I hear you about the stations not permanent, my shop is in constant motion.

What size grizzly and how's it working?

It's probably oversized for my shop, but I got it at an estate sale on the cheap.

I'll probably need to spend another couple hundred bucks in adapters and piping (I have a mix of brands of tools, so no two have the same size outlet) but it should be cool when finished.

It works okay, but one with a cyclone would be better.
