Sorry for the confussion guys. I had what had to be the worst day in fifteen years at work yesterday and I,,, well, I had my head up my butt and wasn't thinking to clearly.

Now, let's see if I can clear this up fer y'all.

Tannic acid (it's what's in the tea) and ammonia are what creats the reaction in the wood. Some woods have tannic acid in them and some don't.

Walnuts and oaks already have tannic acid in them. Mother nature put it there so's we don't have to. Ain't that cool of her?
Maple and some of the other blond hardwoods don't have tanic acid so we have to put it on the wood. Mother nature makes us waste a perfectly good teabag. But it's a fair trade if'n ya' ask me, considering what we get in return.

I'm not sure where he got it from, but I found it in Roy Dunlap's book "Gunsmithing" If you don't have one I strongly recommend it. Goood reading.


"There are three kinds of men
Those who learn by reading
The few who learn by observing
The rest have to pee on the
electric fence and find out
for themselves."
