Here is a 6" long splinter forend I made for an unmentionable rifle alongside the other half of the same piece of cherry that it was cut from.
The forend was sealed with 3 coats of Tru-Oil and set in the South Alabama sun to darken naturally for two weeks. The other half was kept inside in my cutoff box.



If, of course, you are willing to concede that blasting a piece of cherry wood with 280 to 400 nanometer ultraviolet electromatic radiation from an ongoing thermonuclear explosion 93 million miles away is "natural."
