Preparing the Blank:
• Cut blank to the length of the tube, adding 1/16” for squaring off.
• Drill 3/8” hole lengthwise through the blank.
• Spread glue over tube, insert the tube into 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 blanks, making sure the trimmed ends are 90º to the tube. Use a 3/8”
Barrel Trimmer or a 3/8” Sleeve with a pen blank squaring jig on a disc sander. Take the excess material down
flush to the ends of the tubes. Do not trim past the end of the tube since this may interfere withv assembly and the
operation of the mechanism. Use a barrel trimmer to clean the inside of the tube.
DIAGRAM B / TURNING THE BLANK
• Mount the bushings and blanks according to diagram B.
• When using Mandrel Saver, there is no need for extra spacer bushings or the
knurled nut. Slide and lock tailstock directly against bushings and tighten quill
until blank and bushings are secure.
• To Used Knurled Nut setup (right), add spacer bushings unitl past the threads
on the end of the Mandrel Shaft.
• 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 Tailstock and hand tighten the quill adjustment with wheel to steady the
mandrel. Do not over-tighten, it could damage mandrel shaft.
• Using sharp tools, turn the blank down close to the bushing diameter. Turn the
barrel straight or to a profile of your choice.
• Sand the blank down to be flush with the bushings, gradually increasing
sandpaper grits.
• Finish the barrel using your choice of polish. Allow sufficient time for the polish
to cure—refer to polish instructions.
