This is a short tutorial showing the steps of carving a rifle stock. The first photo shows the stock to be duplicated being set up. I use a laser to make sure everything is straight by putting a 3’ rod in the rear bolt hole. The laser line on the rod helps get the top of the stock 90 degrees to the action. At the top of a 3’ rod you can see if the stock is tilted just a few thousands of an inch. It’s hard to put a level on the side of a curved surface.
The second photo shows the blank being lined up as well. This stock is for a Winchester Model 70 and the blank is made from ambrosia maple, black cherry and walnut. The stylus is shaped to match the cutter and it follows the pattern stock while everything that’s not a stock is cut away from the blank. The duplicator isn’t the crutch you’d think. The stock still has to be carved. Notice the guard on the router! I’d like to install one, but so far I haven’t found a way to fit one that will let me see everything I need to see. A dust collection system would be great too. I traveled all the way from Tennessee to South Dakota to the factory to see how they handle dust control. Yep, they put the machine in a room, close the door and the operator wears a respirator. Then clean up after the job is finished. Another stockmaker I visited only has 2 walls on his shop, the ends are open and he blows a huge fan while he carves. It’s ok in the summer, but it has to be freezing in the winter.
The third photo shows the stock just before it’s removed from the duplicator. IT takes 1 to 1 1/2 hours to carve a stock, then it takes about an hour of sanding to result in a stock that’s ready to fit to an action. The final sanding, bedding and finishing can take days.
The fourth photo is to show how close the dimensions can be duplicated. The bottom inlet is .007 smaller than the pattern. That gives some room to allow for variations in factory actions. You can always remove wood, but it’s hard to add any if you cut the opening too big.
The final two photos show the finished stock.
