Sierra Twist Turning Instructions

Sierra Twist pen

Needed:

Mandrel, Sierra bushing 27/64 drill bit

Only one blank (half of a standard length pen blank) is required for this Cut the material blank 1/4” longer than the brass tube so you can square the ends off once the tube is glued in.
Drill the blank through the center, lengthwise, with a 27/64”
Scuff the brass tubes with sandpaper to clean off the oxidation and give the glue a better adhesion
Plug the ends of the tube with a material of your choice – we recommend base plate wax – to keep the glue from getting into the tube. Push the tube ends into a thin section of the material to form a This is important – glue inside the tubes is a common cause of kit failure.
Prepare your glue. We recommend two part epoxy glue – use a fast drying type, one hour or You can also use thick CA glue.
Roll the tube in the glue then insert it into the blank using a twisting motion until the

tube is equidistant between both ends of the blank.

Using a barrel trimmer of the proper size, square off the ends of the blank until you can see bright brass tube. STOP at this point. This can also be done with the proper jig and a disk sander. Not having the proper tube length is another major cause of kit failure.

Assemble the blank on the mandrel using the 20A bushings and following the diagram
Lightly tighten the mandrel and Do not over-tighten the brass nut – this can bend the mandrel which will result in an oval pen.
Turn the pen blank to the desired shape using the bushings as a sizing guide.

After turning, sand the surface in progressive steps until you get to 400 or 600 grit. For a smooth finish, continue sanding with Micro Mesh from 1,500 to 12,000 grit.
Apply a finish of your choice and remove the blank from the mandrel.

Press the finial/clip assembly into one end of your finished
Insert the refill into the nib assembly making sure that the spring is in place.
