I do not know if anyone has ever posted on how to get free wood chips. I went to my local lumber dealer and got a bag of sawdust. Just as you would make coal loads you use the sawdust to make wood chip loads. I got a gallon ziploc bag full today. It will make a lot of wood chips.
Shades of the earlier days of the hobby when you'd pester the lumber yard for free saw dust so you could dye it green. That was the "ground foam" of the era. You had to be persistent because that was also when guinea pigs and gerbils were popular pets and sawdust was used as their bedding (or more to the point, a sort of perpetual pet litter for the overactive digestive process of those animals).
There are supposedly health reasons to avoid the sawdust of certain kinds of treated lumber used for decks and such.

Not really supposedly. You DON'T want to be breathing the dust. But once it's glued down, it will be safe. Should that be the kind of sawdust you get.
Around here, treated lumber is used for framing down onto concrete, which might get damp over time. At least, it used to be used. Haven't seen it for awhile. I think it would make a pretty nasty deck. Maybe for some deck framing.
Tooth size has a lot to do with the fineness of the sawdust. There's times when I want some real fine stuff, and I cut a 1 x 2 with a 32 tooth hacksaw, and get plenty. It's sorta like wood flour.
