Product Information

The Rifle Bolt Pen Kit is a pen assembly kit designed for both right-handers and left-handers. It features a brass finished tube barrel, which can be made out of turned wood or an acrylic blank. The kit includes a clip assembly, tip assembly, refill, and spring.

Product Using Instructions

Preparation and Turning of the Blank

Cut the wood or acrylic blank to the length of the metal tube plus approximately 2 mm. Ensure that the grain runs lengthwise.
Drill a 3/8 diameter centered hole lengthwise through the blank. Use slow and steady pressure to avoid wandering or splitting of the blank.
Glue the brass tube into the blank using epoxy or a gap filling cyanoacrylate. Spread the glue on the tube and insert it into the blank with a twisting motion to evenly distribute the glue. Center the tube lengthwise in the blank and allow the glue to dry. Remove any excess glue residue from the tube.
Square the ends of the blank using a barrel trimmer to finish flush with the ends of the brass tube.
Sand the blanks progressively from 150 to 600 grit paper while spinning.
Apply a finish of your choice, taking care with finishes like polyurethane to avoid sticking of pen and mandrel parts.

Pen Assembly

If needed, reverse the bolt position by loosening the set screw.
Unscrew the end cap and rotate the clip if necessary.
Re-attach the cap.
Lay out the kit parts and finished barrel.
Press the tip assembly into one end of the barrel.
Press the clip assembly into the opposite end of the barrel.
Unscrew the tip, insert the refill into the opening at the tip assembly, and place the spring over the refill.
Replace the tip and lock or unlock the bolt to extend or retract the refill tip.

Note: Do not press the front end of the kit with the tip removed to avoid improper assembly and voiding the warranty.

REQUIRED ACCESSORIES

fig-1

7 mm pen mandrel bush
2 piece bushing set, BUSH-8000
3/8″ drill bit, PK-38BP
Universal barrel trimmer
2 part epoxy glue or CA super glue (cyanoacrylate)
Wood or acrylic blank, minimum size 5/8″ x 2 1/4″
Sanding and finishing supplies

PREPARING AND TURNING THE BLANK

Cutting the wood or acrylic blank
- Cut one blanks to the length of the metal tube plus approximately 2 mm. Grain should run lengthwise.
Drilling the blank
- Drill a 3/8″ diameter centered hole lengthwise through the blank. Excessive pressure will cause the drill bit to wander and/or split the blank. Slow the feed rate and back the bit out repeatedly for chip removal.
Gluing the brass tube into the blank
- Use epoxy or a gap filling cyanoacrylate. Spread the glue on the tube. Insert into the blank with a twisting motion to spread the glue evenly inside. Centre the tube lengthwise in the blank. Allow the glue to dry. Remove all glue residue from the tube.
Squaring the ends of the blank
- Use a barrel trimmer to turn away the excess wood to finish flush with the ends of the brass tube.
Turning the blanks
- Mount the bushings and the blanks on the mandrel as shown in figure 3.
- Thread on the knurled nut and hand tighten to hold all components in place.
- Slide the tailstock up snugly against the mandrel shaft inserting the live center point into the mandrel dimple, lock in place.
- Hand tighten the quill adjustment to firm up the mandrel. (DO NOT overtighten, it could damage or bend the mandrel.
- Using sharp tools, turn the blank down close to the bushing diameter. Turn the blanks down to a diameter slightly larger than the bushings. As you approach the final size be careful since the wood is only about 1 mm thick above the brass tube.
Sanding the blanks
- As with any sanding, progress through a range of lower to higher grits of sand paper. Sand with blank spinning. Progress from 150 through to 600 grit paper.
Finishing
- Try a finish of your choice but be careful with finishes such as polyurethane as there is a risk the pen and mandrel parts sticking together. Some finishes can be applied with a rag whilst turning the barrel on the lathe.
