I suddenly realized I hadn't posted any of my rifles. The first picture is of the "Wolf Rifle" that is for sale now at http://www.etsy.com/shop.php?user_id=6823431 . It is cut into quarter inch cottonwood and laminated onto half inch mahogany. The rifle stock itself is sixteen inches long. This is just one of several patterns I use. I've seen them listed in several places, but mine come from http://www.woodcraftplans.com/osc/ .
If you look at the bottom, smaller picture, you will see a difference. That one was cut before I bought the invaluable addition to my shop, the planer. Back then I simply cut them out of three quarter inch wood and left them open on the back. As you can see, the mahogany I add now makes a much more dramatic effect. Either of these would look great though on anyone's mantle or shelf.
Later, I'll try to get posted some pictures of the other rifle designs I do.
