Thank you, the stock is growing on me. A little darker than I planned, but it sure highlights the curl.
I wiped kibler's tannic acid solution on the wood and let it dry over night, followed by ferric nitrate and then went over the whole thing with a heat gun. I almost had a stroke because the stock turned pitch black. Then I scrubbed back with a fine scotchbrite pad and mineral oil. The curl slowly appeared and I was able to control it by the amount of scrubbing.
After that, I wiped the stock with solvent mineral spirits/acetone to remove the oil and let it sit for a day or two to make sure the solvent was completely dry. Next, I wiped LMF maple stain to give it the red overtones, let dry and the final finish is maybe 5-6 coats of Permalyn gun stock finish, rubbed in with my finger tips. Let dry between coats and rub lightly with a gray scotchbrite pad to take out defects. It makes for a very clean, smooth finish that's fairly robust and really adds depth to the curl.
This is the first time I've used this finish schedule with the tannic acid and I kinda like it. If I had to do it different, I'd try some polymerized Tung oil instead of the Permalyn. The better quality tung oil is hard to find locally and I didn't want to wait for the shipping so I used what I had.
Thanks for looking
