I have some solid, untreated 3/4" x 1-2" x 16" maple scraps at the shop
where I work. I know there are several types of maple. But as far as
using it for smoking, is all maple pretty much the same?

I have a fair amount of it, too. If anybody in Austin wants to pick some
up near Live Oak Brewery and Smokey Denmark Sausage (places y'all might be
able to relate to... ;-), then let me know. It's not enough to fill your
firebox, but it's a few hundred hours worth of smoke when used to
supplement your lump. I can spare at least 20-30lbs at a time.
