I will preface by saying I am FAR from a pro....I have finished exactly 1 rifle...in fact it was the only piece of maple I've ever finished...
I wanted the curl and figure to pop and have a rifle that is something to look at....
I did a lot of reading and trying to figure out how to accomplish that...
Through what I read I decided for my approach to do the following..
I started by scraping the stock rather than sand it...I had NO idea that scraping was a thing...while working on the rifle I noticed areas that I cut clean were very clear and hard...areas that I sand were sanded..a soft feel and not the clear appears...it made sense to me to scrape not sand..
I whiskered and scraped 3x I think...
I then used Kiblers's tannic acid and then iron nitrate...I wanted to turn my curl dark and try to keep the wood light and give it as much contrast as i could... looking back I should have really slathered on both products on heavily and maybe did a 2nd application of the iron nitrate but I didn't...
After hearing the iron nitrate I used Chamber's oil finish on a piece of scotch brite to rub out the acid finish to the color I wanted...
I oiled the stock heavily and let it hand and kept it wet...then after it seemed to soak up what it was going to I went over it lightly to clean up the excess...I let that dry hard a couple days...
From there I burnished it with an antler and finished it by hand...rubbing out the coats of oil with rottenstone in between...time consuming...messy...extra dry time...but gives a clear hand rubbed finish...
The finish, to me, is amazing...it's truly holographic in a sense... different lighting, angles, etc change the way the stock looks...
I had no idea what I was doing....but I am very pleased with the finish of the rifle...
I've never done a scraped finish...I left a few marks but I learned a good bit...
The acid finishes were fun...you can see I highlighted some areas on the check piece and forearm and left areas like around the lock and cheek piece darker...I didn't intend to do that but rubbed a little much on the cheek piece and realized I could do what I did pretty easily and give it a bit or a worn appearance...I think it turned out alright for my first attempt...
