Preparing the Blank:
• Cut 1 blank to the length of the tube and add 1/16” for squaring off.
• Drill a 3/8” hole lengthwise through the blank.
• Spread glue over the tube, insert the blank with a twisting motion to spread the glue evenly inside.
• Center the tube lengthwise inside the blank.
• When the glue is dry, square the ends of the blank. 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.
