Instruction for 24ct Americana Classic Twist Pen Kit ...

Pictures of the finished sample articles, in acrylic, can be found in our catalogue in

the 'Woodturning Projects' Section.

Below is a list of the items required to make the finished items from the purchased

kits. (Not including the body blanks). If you do not possess these items we have

offered our catalogue stock code numbers alongside the items as a quick guide. We

have tried to include everything in the list, although we realise that many

woodturners will already have most of them.

Preparing the Bodies...

Using 16mm (5/8") Square stock; cut the blanks to the length of the brass tubes

adding 2-3mm to allow for trimming. The Pen Blank Sizing and Cutting Jig makes this

process very much easier.

Order No:

Drill an 11/32" diameter hole through the centres of the blanks. Care must be taken

211322

211323

not to force the drill bit, (this may cause it to 'wander' from the centre line), and

remember to back out the drill frequently to clear the debris from the hole. If you are

using a pillar drill the Quick Action Pen Blank Vice is a very useful accessory for this

340202

340203

task, it ensures that the blank is held upright and firmly in position. Moreover, if the

vice is clamped to the table of the drill, it will provide accurate repeatability for all the

340204

blanks that require drilling.

When the holes are drilled, spread the adhesive randomly over the brass tubes and

702557

insert the tubes into the blanks using a twisting motion to ensure the glue is spread

evenly between the two surfaces. Over insert the tubes into the blanks by

340282

approximately 1mm giving an allowance for the blank to be trimmed to size and the

990095

excess glue to be removed (See Fig 1).

Warning. If you are using cyanoacrylate adhesive, exercise extreme caution and

(i)

do not allow the adhesive to come into contact with the skin. If this happens

(j)

keep the affected area from contact with any other surface, until the glue has

hardened or you can treat the area with a softening agent similar to Zap Z-7

(k)

Debonder (990099), and you can remove the glue.

Allow the adhesive to dry thoroughly. Using the Barrel Trimmer trim the ends of the

blanks squarely and neatly to the ends of the brass tubes; this will also remove any

excess glue that may have exuded from the joint. Take care not to undercut the brass

tubes.

Turning the Bodies...

Slide the Mandrel Bush onto the shaft, add one of the bushes from the bushing kit ,

next slide on one of the blanks, add two more of the kit bushes (back to back) add

the other blank, then the last bush from the kit. Slide the mandrel up to the end of

the blank, spin the Locking Nut onto the mandrel and finger tighten (See fig 2).

Live tail stock centre

Mount the mandrel onto your lathe; and tighten the lock nut to allow the assembly

to be turned without moving. Do not overtighten, this may cause the assembly to

distort, the bodies to split or strip the thread on the lock nut etc. Similarly do not

advance the tailstock centre with too much force. The current bulk of the blanks

may be adding strength to the assembly but as the body diameters are reduced,

too much force on the mandrel may cause it to distort or bow. Turn the main body

dimensions down to the guide diameters of the bushings. Sand and finish the

bodies. Remove them from the lathe and the pen mandrel (See fig 3).

General Assembly...

Note. The Axminster Pen Assembly Press (200205) is a very useful accessory for

these operations, as it gives greater control over the applied force and keeps

the components in line (See Fig 4).

Fig 4

Line up the Lower Pen Body components as shown in (Fig 5). Make sure the black

tip extention (i) and the tip (h) are aligned and firmly press the two items together.

(force fit) Ensure the lower band joining insert (d) is aligned with the lower body

and firmly press together (force fit). Put these two partial assemblies aside

temporarily.
