Large platter

   This project is the largest piece Ive ever attempted. I guess it will end up being a platter, or shallow dish, except it's about 35" by 28" and its natural edge.
   As I write, this piece is a work in progress. The piece started as a slab or slice from a large tree, limb, or burl of some sort.
  Im not even sure what type of wood it is. 
At this point I've glued waste blocks centered on                         
both faces, mounted it outboard, and rough turned 
what is going to become the bottom.
