Thanks everyone for the comments and interest. Rolfkt, I will post some pictures of the butt cap in a few days. Bill, no worries about wire. I think George had me confused with my evil other self, Dave "black". As long as I stay Dave "white" there will be no wire touching those pistols. Didn't Cody have a saying about hearing the voices? Capt. Jas, black walnut often has a slight purplish brown color very different from English walnut. I give the stock a wash in yellow water-based aniline dye (you could use any yellow stain if you don't like aniline dyes). The yellow completely neutralizes the purple hue and gives the wood a warm yellow or orangy brown close to English walnut. I then may add a light reddish brown stain depending on the color of the wood. I have had really good success with that method. You will be able to judge for yourself when you see the finished pistols.
Thanks again guys
dave
