Product Usage Instructions

Preparing the Blank:

   the tube to avoid interference with assembly and mechanism
   operation.
2. Clean the inside of the tube using a barrel trimmer.

Turning the Blank:

1. Set up the Knurled Nut by adding spacer bushings past the
   threads.
2. Slide and lock the tailstock directly against the bushings and
   tighten the quill until the blank and bushings are secure.
3. Turn the blank to a profile of your choice using a lathe.

Assembly:

1. Refer to Diagram D for the parts layout.
2. Assemble the mechanism by attaching the spring and refill to
   the lever.
3. Ensure that the tapered side of the spring goes on the refill
   first.
4. Follow the manufacturer’s instructions to cure the polish
   before using the pen.
