Are used to make turned maple lumber which in turn is used to make totems.
This holds true in all the tiers, making lumber out of raw wood always results in the lumber and the scraps and all the scraps can be used to make turned lumber.
But, even if you plan to make a bunch of totems, you probably don't need as many scraps as you might think because totem recipes yield a quantity of items per combine - just like WORTs. 1 for crude - 2 for shaped - 3 for standard & 4 for pristine. So without even half trying, you can be buried in totems! Have fun!
