[[File:PenTubeInsertion.jpeg|thumb]]After you have drilled the blank, the next step is to glue the metal pen tube inside the hole. Make sure the tube fits without too much force, and that it can be positioned so that excess wood extends beyond both metal ends. If tear out has occurred, take care in positioning the tube so that the area of torn out grain does not contact the tube itself, if possible. You can use 2-part epoxy or CA glue. Sand the outside of the tube if it is not rough already from the factory. Cover with a thin layer of glue. Use the conical insertion tool (stored in the Pen Tools box) to inert the tube into position inside the blank, and let the tube dry.<br clear=all>

The next step is to trim the wood exactly perpendicular to the pen tube, and to the exact length of the tube. At present, we have only one method of blank trimming: a universal pen trimmer. We anticipate getting a disk sanding jig at a future date.
=== Universal Pen Trimmer ===
This set consists of a steel 4 blade cutter or a 2 blade carbide cutter. The steel cutter is fairly dull and cuts slowly. The carbide cutter will cut aggressively and is more likely to tear out end grain. One of four inserts goes through the center of this, and is held in place with a set screw tightened using the attached Allen wrench. (The set screw for the carbide cutter appears to use a different sized Allen wrench!) the following inserts are available to square pens with tubes of the following diameters:
* 7 mm
* 8 mm
* 3/8 inch
* 10 mm
The inserts contain reamers that will also trim dried glue from the inside of the tube. Additionally, the kit includes a brass tube that slips around the 7 mm reamer so it will fit tubes used for the #PKPARK-PCL and #PKMONT-PCL kits.
It is helpful to secure the pen blank in a vise, or clamp it while trimming, which can help prevent tear-out. Chuck the trimmer in a drill and then trim the wood square and exactly flush with the tube, taking care not to shorten the tube appreciably.<br clear=all>
