A well used suggestion.............If you like black highlights on curly maple , and you don't want your expensive curly maple to be all black , and maybe turn green down the road, just use straight uncut , Fiebings black alcohol stain. If in a hurry , dry the wood w/ a heat gun. When dry and warm to the touch , #OOOO steel wool the whiskers off. If it is desirable to make the rifle a Southern Appalachian black rifle , double up on the black stain another coat , dry w/ heat gun again to touch,and feel.
I prefer the ability to adjust the shades in the staining process. If color is desired to match some color scheme on an original rifle ,mix up some red , yellow , to make an orangeish red back color to the black base color. The black , stains the soft wood in the stock , and the color shades stains what's left. Again , always dry the wood w/heat gun after staining and steel wool any remaining whiskers off. Since the wood is dried immediately after application of the alcohol stain , steel wool rusting , which I've never seen , is not an issue. After final stain coat and drying w/heat , the wood is ready for a penetrating coat of finish. Once this initial coat of finish is dry , finish how ever you like... I don't use linseed based finishes , but if it works for you, good............oldwood
