As I was planing a board of oak, I noticed an acidic vinegar-y smell emanating from the newly exposed surface and the shavings.
I read this might be due to natural acids present in the tree. I didn't cut the tree down, rather I have purchased the board, already surfaced on 4 sides. I'm not sure if it's received any treatment - The label (from the big orange store) simply said "oak".
I don't mind the scent, but:
Is it a sign that i should let it dry off a bit more?
If it was indeed acid causing this, would I need to neutralize it before applying certain finishes?
