What causes the hickory to do that? I've seen some hickory and never anything like that. Is Honey Comb a type of Hickory?
"Honeycomb" is just a name I coined to describe the figure in the wood. This is pignut hickory that fell and has been laying on (or slightly off) the ground for years (I suspect over 25). The honeycomb pattern is formed by little pockets of decay - similar to spalting, but with a cellular look and no black lines. I've harvested quite a few hickory trees, but only come across 3 with this figure in them.
Depending on how far gone the decay has progressed, it can be quite punky and challenging to turn. This bowl was mostly solid, but with several soft spots that needed CA to stabilize. Despite being dead for decades, it was still wet when rough-turned. I put it in a paper bag filled with wood shavings in May, and finished it in December.
