WriteMaster Click Pen Instructions
WriteMaster "click" pens use two barrels, both made from wood
blanks measuring 1.75" (44mm) in length by about 5/8" (16mm) square
cross-section. The blank for the upper barrel has a 0.433" (11mm) hole; the blank for
the lower barrel has a 0.315" (8mm) hole. WoodWrite, Ltd. pre-cut,
pre-drilled wood blanks for WriteMaster pens are sold in packages of ten (10)
blanks, suitable for five (5) pens. The blanks are marked to show grain alignment. Be sure
to maintain the orientation of the top and bottom blanks as you proceed if you desire to
have the grain match, top to bottom, in your finished pen.The 11mm lining cylinder for the
upper barrel is 2.11" (53mm) long, longer than the wood blank by about .36"
(9mm). This extra brass protrudes from the lower end of the top barrel (when holding the
pen tip downward) and provides support for the three piece decorative ring.
WriteMaster pen barrels are turned on a two level mandrel the WoodWrite,Ltd.
KT-21. This mandrel has an 11mm level for the top of the pen and an 8mm level for the
bottom of the pen.
Prepare a pair of blanks with lining cylinders, as described in Preparing Wood Blanks,
paying particular attention for the upper barrel (11mm cylinder), that the ends of the
barrels are flush. As for all WoodWrite, Ltd. blanks, be sure to let the
adhesive cure overnight before turning, and, remove excess glue that may have hardened
around the exposed end of the brass cylinder.
1.When using this mandrel, place the glued top barrel on the mandrel with the
exposed brass to the right, then place on the two level spacer with the larger level
against the exposed brass. You then place the glued bottom barrel on the 8mm portion of
the mandrel against the two level spacer. The single level spacer goes on next followed by
the tightened knurled nut. Be sure the needle center of the tailstock is tightly engaged
into the right end of the mandrel.
2. Move the saddle to the left so that the cutting tool is aligned with the gage
point of the mandrel. Turn the micrometer dial counter-clockwise until the tool just
touches the gage point ("0") then back the tool away by turning the micrometer
dial four complete turns clockwise ("0"). If the micrometer dial does not read
"0" when the tool is just touching the mandrel, reset the zero point.
3. Make your first cutting pass, moving the saddle from left to right.
(0.732"[19mm] diameter) You will cut across the gap between the blanks, to turn both
blanks to the same dimension.
4. Turn the micrometer dial counter-clockwise one full turn to "0".
Make your second cut, moving the saddle from right to left. (0.632"[16mm] diameter)
5. Turn the micrometer dial counter-clockwise one full turn to "0".
Make the third cut, from left to right. (0.532" [13.5mm] diameter)
6. Turn the micrometer dial counter-clockwise to "35" and make your
fourth cut, from right to left. (0.502" [12.8mm] diameter)
7. Turn the micrometer dial counter-clockwise to "30" and make your
fifth cut, from left to right. (0.490" - 0.492" [12.4 - 12.5mm] diameter) You
have finished cutting the top barrel; the cutting tool is to the right of the bottom
barrel. The remaining cuts will be on the bottom barrel only.
8. Turn the micrometer dial counter-clockwise to "40" and make your
sixth cut on the bottom barrel only, from right to left, stopping between the barrels.
(0.412" [10.5mm] diameter)
9. Turn the micrometer dial counter-clockwise to "30" and make your
seventh cut from left to right. (bottom barrel only). (0.392" [10mm] diameter)
10. Turn the micrometer dial counter-clockwise to "27" and make your
final cut from right to left, bottom barrel only. (0.385" - 0.388" [9.8 - 9.9mm]
diameter) Stop the lathe and turn the micrometer dial clockwise three and one-half turns
to "0". Now, move the saddle to the left end of the lathe bed to be out of your
way for smoothing and polishing as described previously. (The tool is positioned to start
another WriteMaster pen, step 2,
In summary, your tool settings are as follows, starting with the tool just touching the
gage point of the mandrel:
CLK 0000 - CCLK 0 - CCLK 0 - CCLK 35 - CCLK 30 (both barrels)
(continuing) CCLK 40 - CCLK 30 - CCLK 27 (bottom barrel only)
Smooth and polish the barrels.
The components of a WriteMaster pen are shown below. You have already used
the two lining cylinders in the two wood blanks to make the barrels. You will need one
each of the black end cap, clip, brass ferrule, 3-piece decorative ring assembly, click
mechanism, gold ferrule, one piece decorative ring, black tip, gold tip, ink cartridge and
1.Press fit the brass ferrule into the top end (where the cylinder and the wood
are flush) of the upper barrel (containing the 11mm cylinder).
2. Press fit the three piece decorative ring (gold-black-gold) on to the brass.
If you have difficulty placing the three-piece ring on the brass, with a fine-toothed
file, lightly chamfer the exposed end of the 11mm brass tube. Dont overdo it;
dont distort the tube. A slight chamfer all the way around will enable you to start
the ring assembly onto the cylinder and press fit it properly.
3. Press fit the gold ferrule into the end of the bottom (8mm) barrel that will
be opposite the tip (if grain alignment is of concern to you.)
4. Align the gold tip, black tip and decorative (black striped gold) ring at the
other end of the barrel and press fit together. Be careful not to over tighten to avoid
splitting the black tip.
5. Place the spring over the tip of the ink cartridge and insert fully into the
bottom barrel. The ball point wont be visible at the point end of the barrel.
6. Place the click mechanism over the end of the cartridge and screw the
threaded end onto the exposed portion of the gold ferrule. Test the click mechanism by
pressing the end while holding the barrel. The point will extend, and, with the next
7. Check the clip to be sure the angle between the loop and the stem is acute
(less than 90E) to ensure proper pressure on barrel after
assembly. Screw the threaded stub of the black end cap through the hole in the clip, into
the ferrule, to secure the clip.
8. To replace the cartridge, remove the black end cap and clip. Slide off the
upper barrel. Unscrew the click mechanism. Remove the cartridge and spring. Place the
spring over the tip of the new cartridge, insert in the pen and reassemble. Caution:
It is possible to open the pen by turning the upper barrel, however, disassembly in this
manner opens the click mechanism and may result in loss of or damage to its spring.
Q & A
! Once in a while when Im making WriteMaster pens,
the cap (upper) barrel seems to bind on the lower barrel.
Remove the ink cartridge and spring from the lower barrel of the pen. Slide the lower
barrel unto the mandrel as far as it will go. (You wont be able to use the knurled
nut, but thats okay.) Bring the tailstock center to the barrel, inserting the point
of the center into the gold tip of the pen barrel. Lock the tailstock in place. Re-sand
the portion of the barrel where it is binding (near the top, at the gold ferrule.) If you
rub the finish off the ferrule, dont worry. The ferrule is hidden by the cap after
assembly. Refinish the barrel with whatever polish you first used, and buff lightly with WoodWrite,
Ltd. light finishing compound (CN-03). Re-assemble the pen and
you should find that the binding problem has been eliminated.
! I have difficulty in attaching the three-piece decorative ring assembly
onto the exposed brass portion of the WriteMaster upper pen barrel.
The tolerances are quite close to ensure a good, tight, fit, but, if youre having
problems, using a light touch and a fine-toothed file, gently chamfer the exposed end of
the 11 mm brass tube, taking care not to distort the tube. A slight chamfer, all the way
around, will enable you to start the decorative ring assembly onto the tube. Your WoodWrite,
Ltd. assembly press will then finish the job.
