Tannic acid qustion

[Ezra]

Hey guys,

I’m sitting here on the couch enduring day 4 of COVID and am going stir crazy.  So, I thought I’d ask a question I’ve had for a long time.

There are some woods used for stocks that naturally have high or moderate levels of tannic acid in them.  If memory serves, Chestnut, cherry, oak (white & red) and walnut are all examples.
Now, if this is so, how is it we don’t get substantial rusting of metallic components when attached to these type stocks?  Thanks guys.

If I am not mistaken, those species have a higher tannin content - not tannic acid.  Tannins are an organic molecule.  Tannic acid is a specific type of tannin.
