Process Rifling Machine

Groove Depth: Do not try to go too deep anc keep the chisel perpendicular to the cylinder. Cut along both sides of the channel groove approximately 4-5" at a time. (See step 9 - Depth Gauge) See Figure 34)

4. Using a 1/4" chisel, now hollow out the wood between the two cuts. Note, fir wood spits very easily, do not try to go to go too deep at one time. See Figure 35a

5. Work slow, making sure you follow the lines as close as possible.

9. DEPTH GAUGE: Continue wood removal for the entire length of the groove. It works best if you remove the wood in layers of about 1/8" at a time. You will arrive at proper depth when the groove bottom is at the same level as the handle and tail stock axle's surfaces. Use the depth gauge along the length of the worm to keep your depth consistant. See Figure 36 &37

6. Rotate the cyclinder often as you work. Keeping the chisel perpinducular to the cylinder and cut on the lines.

7. KNOTS: Remember you have little control cutting through knots!! Use a 1/4" chisel to help you cut through the knots that may be on the sides of the grooves. If pieces of knots or wood splits occur on the sides of grooves, repair later with a good grade of epoxy.

8. Constantly watch the angle of your chisel to minimize under cutting the groove walls. Use the GROOVE WIDTH GAUGE to ensure you have the proper width of the groove. See Figure 35b

Fig. 37

10. Once you have gotten the groove to the proper depth, go back and use the Groove Width Gauge to check the grooves for proper width and wall straightness. Another aid is to use a straight edge or metal ruler to lay along the groove and see if there is any extra wood. See Figure 38

11. Mark the wood, and chisel the wood away. Use the 1" chisel and position the chisel so it is flat against the side wall of the groove. See Figures 39 thru 41

Change Rate Of Rifling Twist - This can be accomplished by shortening or lengthening the long arm of the angle drawn on the floor. (Reference section Laying Out The Rifling Grooves) Measuring out tne long leg to 60" would give a twist of 1 in 60. Conversely, a 1 in 32 would have a long leg of 32".

Worm Groove Too Wide: If too much wood gets removed from the sides of the grooves or splits badly; use popsicle sticks and epoxy to repair the sides of the groove.

Wooden Worm - Fir may sound soft, but it will last dozens upon dozens of barrels if you keep it dry and use plenty of paraffin in the grooves.

Index Marks - You may wish to make a mark or number each rifling groove or at least identify the number one groove. This aids you in identifying which groove you are cutting in the rifling process. We normally place our mark approximately 10"-12" from the index area of the worm. Below are a couple of ways you can mark your rifler. Use your imagination.
