Flamed birch and aquafortis refinish
It's been awhile since I've posted here. So long, that I couldn't remember my password or the system has changed-forcing me to re-register, and I'm pretty sure my email address has changed.
I thought I'd share my recent refinish project. I did a lot of searching for aquafortis and refinishing figured birch. Very little useful information on aquafortis and birch other than curly maple and figured birch are similar and it should work. That was an opinion and not based on experience as related to how the aquafortis should work on birch. Lots of information on aquafortis and curly maple.
After cleaning the stock, I noticed that the birch was much darker and golden orange than the lighter blondish maple I've seen. I was worried it may darken the birch too much.
I cleaned the stock with several applications of mineral spirits and 0000 steel wool. Then several applications of acetone and steel wool. Next was the application of aquafortis followed by heat from an industrial heat gun. I did this twice and stopped when the stock had the look I wanted, per the instructions.
Several coats of BLO and then finished with BLO/turpentine/beeswax. I can't tell if the aquafortis had a major impact on the end results or if it was the BLO and 1/3 mix. I guess it did change enough for me to stop after 2 applications of aquafortis. Since I was dealing with acid, I don't have any middle stage pics. Before pics taken by the seller of the stock as "before". "Finished" pics taken by me. Minimal filtering applied. Photos depict end results perfectly as seen in person.
What do you all think? Did the aquafortis change the end result at all? Pics to follow:
