Preparing the Blank:

• Cut 2 blanks to the length of the tube(s) and add 1/16” for squaring off.

• Drill 3/8” holes lengthwise through the blanks.

• Spread glue over the tube(s), insert the blank with a twisting motion to spread the glue evenly inside.

• Center the tubes lengthwise inside the blanks.

• When the glue is dry, square the ends of the blanks. Use a 3/8” barrel trimmer, or a universal pen blank squaring jig

with a power disc sander. Take the excess material down ush with the ends of the brass tube. (do not trim beyond

the length of the tube since this may interfere with operation of the mechanism and assembly). Use a barrel trimmer to clean the inside of the tube.

Turning the Blank

• Mount the bushings and blanks according to diagram B.

• 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 rm up the mandrel. (DO NOT overtighten, it could damage the

mandrel.

• Using sharp tools, turn the blank down close to the bushing diameter. Turn the barrel (straight or to a

prole of your choice)

• Sand the blank down to be ush with the bushings gradually increasing the sandpaper grits.

• Finish the barrel with your choice of polish. Allow sufcient time for the polish to cure.

Refer to polish instructions.

Assembly

• Layout parts according to diagram A

• Press the tip into either end of the shorter barrel.

• Press the center band assembly into the opposite end of the barrel.

WARNING: It is not advised to press directly over the threads, instead use

a pen blank. Cut a section 5/8” long. Drill an 8mm hole through. Afx this

blank over the threads and press the band and coupler in.

• Remove the tip protector, afx the spring over the rell and drop into the opening at the band. Screw on

the mechanism over.

• Press the cap connector into the larger diameter end of the upper (longer) barrel, ush with the shoulder.

• Afx the clip into the threaded stem. Screw on the cap.

• Engage both ends to close the gap. Twist the upper cap so the clip aligns with the band as shown in the

photo of the nished pen.

• The pen operates by twisting the ends to advance or retract the rell.

• Replace the rell by unscrewing

the upper barrel from the mechanism & exposing the top

of the rell to replace.
