Thanks everyone for the warm response. Glad you've liked the website and the project I'm working on.
As far as burl maple goes for gunstocks, there's good and bad. It's beautiful wood, but requires a lot of work to use often has a lot of defects that must be dealt with and it isn't the strongest, particularly in the forestock. But it is so spectacular I think it's worth the downsides. The best 17th century builders must have thought so too.
Carving does pose a bit of a problem when working back the blackened finish. Scotch-Brite helps with this as do little bits of paper or even light scraping. In some ways, this is not a problem though, as it shades the carving. This is often something I do in subsequent finishing operations with colored finish and glazes.
PPatch: Walnut may occasionally have burls, but it's more likely just some variant of normal log figure in the stock. Perhaps crotch figure. The burl wood I'm speaking of comes from an abnormal growth on the side of a tree as shown in the picture on my blog post.
Thanks again for all the encouragement. This has been a big project, but fun. Few people work on guns of this style and period and it's good to see the positive response. I do believe this might be the first burl stocked gun of this period made in modern times. Well, at least I can't ever remember seeing another...
Any questions or comments, let me know. I'll be adding more blog posts before too long.
