What did you use to slab it?
I bought an Alaskan mill a year or two ago and run an Stihl MS881 on it. I've got 15-20 other slabs at different places, mostly in my dad's barn stacked up with stickers like others have suggested. I have some oak and a good bit of poplar.
I've never slabbed Hickory though, that will be a new one. Usually that 881 will peel off strips and large chips, but this red oak and the hickory it looks more like normal sawdust, and that's with a brand new chain.
