The following
photos illustrate how to use metal-cutting equipment & techniques to make wooden
pen kits.
Caution:
Always wear
safety glasses
& breathing
protection especially when cutting & sanding Cocobolo.
Wood dust can be highly irritating to eyes & lungs or can
even cause an adverse reaction.
Pen Body
Euro pen instructions.
Automatic center punch used to eyeball the center for drilling.
After cutting the wood into two
lengths, they are drilled
with a 7mm Brad-point bit.
The brass inserts are lightly sanded to break the shine &
then super glued into
the Cocobolo blanks.
Insert & glue the brass tubes so that they are almost flush to the middle
of the wood piece.
This minimizes the amount of wood removed by the counter bore thus keeping the
grain continuous.
A reamer is used
to counter bore down to the shinny edges of the brass inserts.
The brass is barely cut by the reamer, too.
A small zero-flute
countersink is used to deburr the brass tubes.
With the original grain aligned the blanks are mounted onto
the arbor with the spacers for a Euro pen kit.
Use of a live center is mandatory.
Cocobolo pen bodies being turned on the Jet 9x20 using
a (OEM Taig) round-nose tool bit & power feed.
A 10.5mm diameter x 5mm long tenon has been cut with a cut-off tool bit.
Setting the lathe DRO to metric
units thereby matching the instructions, made cutting the tenon
quite easy.
The
wood has been waxed.
The lathe's compound was used to cut the two different
tapers.
Animation showing how the pen tip is pressed in using the
bench vise. Aluminum jaws do not mar
the parts.
The twist ink cartridge mechanism is pressed into the body
using the arbor press.
It's an iterative process of press & test to make the ink cartridge tip protrude properly.
The assembly order is important so follow the instructions carefully.
Animation showing how the pen top is pressed in using the
bench vise. Red Loctite secures the
insert.
The cap is loose (screwed out ½ turn) so as to push the top plug slightly below
the end's surface.
The top nut with the clip are then attached with some red Loctite.
Animation showing how the pen ring is pressed on using the
bench vise. Super glue the ring if
needed.
Aluminum, Corian & Cocobolo pens.
Arbor Press
½-ton arbor press used to assemble pens &
other things.
Delrin, Teflon & brass faces for the working surfaces (ram & anvil) are
interchangeable.
Softer surfaces eliminate/reduce damage to the part. The lower arbor plate can be removed
for more clearance.
The mounting
plate was modified to allow a two-position bolt-down to
hard points on the bench.
It has six adjustable metal feet. The front of the press can hang over the bench
edge for long parts.
Wine
Bottle Stoppers
This style does not work well. Recommend the silicon seal
type.
Retro 1930s car knob shapes.
Used the
ball turning accessory.
Tagua (vegetable ivory) is
easy to machine but often has internal cracks.
Left three, are aluminum & the two
right, are stainless steel. Incorporated SS fender washers as
shields.
The washer hole was too large (thus off-center) so there is a small, shallow collar turned onto the
shank for centering.
The washers were burnished on the lathe at the same time as was the sphere. Blue Loctite
secures the threads.
The stub is ½" diameter x 0.84" long & the ends are chamfered 45º.
Used the 5C collet depth stop
for speed & consistency.
