Rialto Rhodium Roller Ball Pen Kit

Pictures of samples of the finished articles, in both timber and 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 blank to the length of the brass tubes

plus 2-3mm (88mm). The Pen Blank Sizing and Cutting Jig makes this process very

much easier.

Drill a 13/32" diameter hole through the centre of the blank. Care must be taken not

to force the drill bit, (this may cause it to 'wander' from the centre line), and

Order No:

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

211323

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

340202

blanks that require drilling.

When the hole is drilled, spread the adhesive randomly over the brass tube

(excepting the outer end) and insert the tube into the blank using a twisting motion

212194

to ensure the glue is spread evenly between the two surfaces. Insert the tube into the

610217

blank leaving a 1-1.5mm trimming allowance at both ends. (See Fig 1).

Brass tube

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

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

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

(e)

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

(f)

Allow the adhesive to dry thoroughly.

(g)

Using the Barrel Trimmer; trim the ends of the blank squarely and neatly to the end of

the brass tube; this will also remove any excess glue that may have exuded from the

joint. Take care not to undercut the brass tube.

Turning the Bodies...

Note. The following procedure is written, assuming a Bushing Set is being used.

It is not a mandatory requirement; if you are not using one please modify the

procedure to suit your own methodology.

Slide a mandrel spacer onto the shaft of the Pen Mandrel. Add the larger Bushing

(13mm) from the Bushing Kit. Mount the trimmed blank onto this bushing. At the

other end of the blank add the 12.25mm Bushing, then slide the other mandrel

spacer onto the shaft; add the locking nut and finger tighten (See Fig 2).

Live tail stock centre

NOTE. The configuration as described above orientates the pen body with the 'tip'

end towards the headstock and the 'top' of the pen towards the tailstock. If you

prefer to turn the body vice versa, reverse the position of the bushings.

Tighten the lock nut to allow the assembly to be turned without moving. Do not

overtighten, this may cause the assembly to distort, the body to split, strip the

thread on the lock nut, etc. Similarly do not advance the tailstock centre with too

much force. The current bulk of the blank may be adding strength to the assembly

but as the body diameter is reduced, too much force on the mandrel may cause it to

distort/bow. Turn the blank down to your preferred profile, sand and finish to the

reference diameters of the bushings. Remove the finished body from 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.
