A friend gave me a log of--best guess-- northern red oak(from the PNW). It's dense and heavy, turns nicely but rusts everything quickly and the freshly turned surfaces develope black spots in the pores and splotches randomly. Any arbor-o-chemists out there that can explain the science of this?? I'm used to the rust, but not this fast
and aggresive. Just wondering if the moisture from the wood is that acidic and what could be sprayed on the rough turnings to mitigate the black staining.Thanks, John
