Steven Russell looks at the plethora of kits and accessories available for pen making

Gallery

The last several years have seen a tremendous explosion in the quantity, quality and types of pen kits and related components that are available. You can literally find hundreds of different types and sizes of pen kits available from various suppliers, from inexpensive ballpoint pens, to elegant fountain pens with solid gold nibs and rhodium accents; there is something to suit every taste and budget.

With so much selection, it's easy to make a custom pen that expresses your own unique style. Many of the pen styles also offer matching pencil kits, which allow you to create matched pen and pencil sets that are perfect for gifts. In last month's article, we took a look at the basic tools needed to turn writing pens. This month, we take a closer look at pen kits, platings, abrasives, pen blanks and popular pen finishes.

Pen kits

Click pens

Traditional ballpoint click pens feature a spring click mechanism that extends and retracts the writing tip by clicking the upper plunger. Click pens are easy pens to turn and assemble and offer a great introduction to pen turning.

Twist pens

Twist pens feature a rotating transmission mechanism that extends or retracts the writing point with a slight turn of the upper barrel to the right, or left. Twist pens are one of the most popular types of pens turned today. The twist mechanism is available on many different styles of pens from slimline through larger body styles.

Rollerball pens

For those who do not prefer ballpoint pens for writing, rollerball kits are available in several different pen styles that use smooth flowing liquid ink. Rollerballs produce a tactile response that is close to that experienced when using a traditional fountain pen, with the ease of a larger refill reservoir.

Fountain pens

If you prefer writing in the classic style with liquid ink and elegantly styled nibs, fountain pen kits are available in various mid-level and upmarket pen kit styles. Two main types are available: those that use a pre-filled liquid ink cartridge inside the body of the pen and those that feature an ink reservoir that is filled by the user with the aid of a small suction device. Fountain pens exude a classic and refined visual elegance that is unmatched by other writing pens. Some of the most expensive pens sold today are based on fountain pen designs.

Upmarket pens

If you're looking to turn something really special, Craft Supplies USA offers a collector grade fountain pen that features a nib of solid 18k gold, with rhodium and 22k gold accents. The pen cap also features an engraved serial number, evidencing the limited number of these pens produced.

Unique and speciality pens

If you're looking for a unique type of pen kit, why not take a look at some of the precision laser-cut speciality pen kits that are available? Several kits are available including those that create the look of a piano keyboard, a jigsaw puzzle, a waving flag, and more.

Metal platings and durability

There are numerous choices available when deciding what type of plating to choose for your pen kit. Beyond the obvious choice of colour, you should consider the durability of the plating, if the pen will be used regularly. The following platings are listed in order of estimated durability. Keep in mind that the thickness of platings can vary from manufacturer to manufacturer, but this can serve as a general guide when determining which plating to consider using.

Rhodium

Rhodium is a member of the platinum family of precious metals and is one of the rarest metals used to plate writing pen components; as of this date, rhodium bullion costs $1,675 per Troy ounce on the London market. It offers supreme durability and brilliance and conveys a rich opulence to any writing pen. Rhodium offers the best resistance to corrosion and tarnish found in the platinum metals family and is highly resistant to incidental scratching as well as abrasion.

Titanium

Titanium plated pens have become very popular in recent years for a number of reasons. Available in both gold and black, titanium offers a less expensive alternative to pen kits plated with precious metals. As you would expect, titanium-plating offers superior wear and scratch resistance compared to traditional gold platings.

Chrome

Chrome plated pen kits are another option to consider if you are looking for both economy and durability in a less expensive kit. Offering a rich silver white colour, chrome plated pens are a great alternative for components that will see heavy use, such as key rings and daily use writing pens.

10k gold

10k gold platings incorporate hard nickel or other alloys to increase the overall durability of the pen. 10k gold pen kits are very affordable, whilst offering a traditional gold looking finished component.

Copper

Copper has a unique elegance to many people. Although copper is a soft metal naturally, the rich colour conveys visual warmth when used as a plating for pens. To increase the wear and tarnish resistance, Craft Supplies USA's pen kits feature a clear epoxy finish.

24k gold

24k gold is also called fine gold and is greater than 99.7% pure gold. 24k gold is softer than many other metals and may wear quickly when plated on pen components. To increase the wear resistance, better quality pens feature a durable epoxy finish over the gold and utilise thicker platings. 24k plated pens are among the least expensive pen kits available and offer new pen turners the opportunity to experiment with pen turning with a minimal capital

investment.

Abrasives

Dry abrasives

Modern dry abrasives, such as Aluminum Oxide, work very well for sanding timber pen barrels. When you are working with oily exotics, or other timbers that load the surface of your normal closed/open coat abrasives, it is best to use abrasives that feature a stearate coating. Stearated abrasives are much less prone to loading on the surface of the abrasive and can effectively sand troublesome timbers without generating excessive heat. It is useful to remember when to use different types of abrasives.

Wet and dry abrasives

Most plastic and resin-based pen blanks require wet sanding to achieve a brilliant lustre. Wet sanding can also be used to perfect the surface of hard cured finishes like Cyanoacrylate, oil, or epoxy as well. Micromesh makes a line of flexible cloth based latex faced wet and dry abrasives that are very popular with pen turners. Nine abrasive grades are available in the Micromesh range starting at 1,800 grit and proceeding through to 12,000 grit. At 12,000 grit, the resulting scratch pattern is invisible to the human eye, creating a near 'wet' looking surface on plastics and other cured finishes.

Pen blank materials

Timber and burrs

Almost any timber can be used to turn pens, but most pen turners prefer to use hardwoods. Dense exotics and burrs are popular favourites as well. High figured local timbers can also be used for pen blanks. Look for timbers that feature a rich colour and a tight figure, since the completed pen barrels have small diameters. Some softwood species can also make beautiful pens, but may require stabilization treatments to harden the wood enough to produce a durable barrel surface. Woodturning suppliers offer regular and stabilised versions of many hardwoods, softwoods and spalted species as well.

Stabilised blanks

Stabilised blanks feature special resins or plastic compounds that have been incorporated into the blank under pressure/vacuum. This creates a blank that looks like timber, but turns like a hard acrylic plastic. Stabilised blanks are the preferred choice for many pen turners who sell pens. Stabilized pen blanks are available in many different timbers, including those that may be too soft in the natural state to make a durable pen barrel, like heavily spalted timbers, or other softwood species. Other types of materials are also available in stabilised versions, including things like buffalo horn, compressed sunflower seeds and corncobs.

Multi-ply blanks

If you prefer a layered look in your pen blank, pen blanks are available that feature thin layers of dyed veneers that are compressed and stabilised. Pen blanks with multiple timbers cut on the bias - cut on an angle to the grain - are also available from most suppliers. These blanks can make very dramatic pens and are a popular choice for many turners.

Antler and horn

Pens turned from deer antler sheds are extremely popular. Deer antler turns easily and when highly polished, resembles granite or marble; it's an amazing material to work with and can produce a stunning writing pen. Water buffalo horn is also available in a stabilised version. The intense black colour of this horn makes a truly elegant looking pen and is easy to turn and finish.

Plastic and/or resin-based

Many different types of plastics and resin-based blanks are available, including acrylics, celluloid, cast plastics, resin impregnated stone dust, and others. These blanks offer richly saturated colours and polish to a stunningly high lustre. If you're looking for something that's easy to turn and finish and is available in a rainbow of colours, take a look at these blanks.

Other materials

If you are looking for something that's a little different, how about a pen blank made from stabilised rattlesnake skin in a clear resin base? Or how about a stabilised corncob blank, or a blank made from stabilised compressed sunflower seeds, known as a Dakota burl? I've even seen pen blanks made from shredded currency, in a clear resin base. The sky's the limit with pen turning!

Finishes

Many different types of finishes can be used on pens, including no finish at all. Unless you're selling your work, the decision of which finish to use is largely personal preference. The finishes listed below are some of the more popular finishes for pens, listed in order of estimated durability when used on a writing pen that will see frequent/heavy use. A rating of (1) is the least durable; a rating of (5) has high durability and resistance to wear.

Paste wax

Wax finishes are preferred by some woodturners when a 'minimalist' type of finish is desired, one that will allow the natural patina to develop over time. Waxes are easy to apply and can be updated by the owner as needed. Microcrystalline waxes have become a popular wax finish in recent years due to their superior protection properties. Microwaxes are neutral in pH and have a high resistance to moisture, some acids, moderate heat and will not show fingerprints on treated surfaces. Durability Rating: (0.5-1.0)

Friction

Friction finishes are a popular choice for new pen turners, since they are inexpensive and very easy to apply. Popular friction finishes include Carnauba wax based friction sticks, shellac based finishes and lacquer based friction finishes. Friction finishes are applied to the barrel surface and cured, whilst the pen is turning on the lathe by applying pressure/heat to the finish. Durability Rating: (Wax based - 0.5, Shellac based - 2.0, Lacquer based 3.0)

Cyanoacrylate based

Cyanoacrylate-based finishes have become popular with experienced pen turners in recent years as they offer a highly durable clear finish that dries quickly. There are numerous ways of applying CA's: some turners use a combination of CA and boiled linseed oil, others use only CA. This is a quick and durable finish for pens, but requires a higher level of skill to apply the finish. Durability Rating: (4.0)

Spray on

Spray finishes like lacquer, offer an easy and convenient way to apply a clear and durable pen finish. Other spray finishes can also be used, including Spar Varnish and acrylic finishes. Although spray finishes are somewhat more expensive than canned versions, the sheer ease of application makes them a popular option for many turners. Durability Rating: (3.0-3.5)

Epoxy

Binary epoxies are one of the more difficult finishes to apply, but can produce a very durable finish. Typically epoxies are brushed on, but may be sprayed as well with the proper equipment. Once applied, epoxies must be constantly rotated at low rpm's until the epoxy cross-links to prevent drips or sags. Once cured, this finish is impervious to almost anything the pen will typically see in use. Durability Rating: (5.0)

Oil based

Oil based finishes can also be used for finishing pens, however, as a group, oils are not a popular finish with most turners. Depending on the specific finish used, numerous coats may be necessary to achieve a sufficient film thickness if a high gloss finish is desired. In addition, each coat of oil must cure overnight in most cases, before another coat can be applied. Durability Rating: (2.0-4.5)
