I wish somebody would try fuming the factory wood with no added tannin because I used a white china wood bar stool inside my chamber and where the finish was not sealed it turned grain a lovely brown.

Stripping supplies to clean stock of factory finish and sealer.

Supplies

Fumming portion
1. 10% janitorial ammonia from Ace hardware (grocery store is only 2-3%)
2. Wine tannin from homebrew shop I used LD Carlson tannin
3. Container to use as fume chamber....do not use metal or copper

Zebra Stripe
1. Cup white vineger
2. Washed steel wool
3. dollar store artist brush

Iron Acetate

Start making your Iron Acetate in a plastic container add vineger and washed steel wool

Do not seal container as it builds up a gas pressure !!!

...let set for at least 48 hours....when done filter thru coffee filters

almost anything it touches will turn black..hands tables etc

Fuming

NOTE TAPE OFF THE PLASTIC GRIP CAP b4 stripping ....DONT WORRY IF YA DONT it will harden back up and can be sanded smooth with wet dry sandpaper

Strip and clean your stock of all factory finish I used Citristrip. After you strip it the factory wood will be real smooth its some kind of wood sealer coat from factory. This needs to be sanded thru I used 120 grit. Sovlents just seen to smear it around and then the tannin will not soak into wood and you will get a light spot

my first fuming attempt I mixed tannin 1/8 TSP to two shot glasses of water and brushed it evenly over while stock or you can use a rag and rub it in seem to go deeper

let this totally dry and soak in

here is my Fume chamber made from a garbage bag and a bar-stool

Stick stock inside with pans with enough ammonia to cover bottoms

Check stock after 1st hour for spots not coloring due to factory sealer

If found remove stock and re-sand white areas and retreat entire stock with tannin mix

Repeat till all areas are taking color

I left mine in over night...with the 10% ammonia seems like color is fully developed after about 4 hours....I changed my ammonia out for fresh when I went to bed

Don't breath the fumes they are hazardous in concentrations but since we are NOT using 26% and up concentrations it no worse than cleaning use common sense

After you are OK with color let stock hang up in open air till ammonia smell is gone from wood before starting your finish coating or oil

wood test chamber...I did samples of a cut off piece of forarm as I was modding the stock
