Polyester Acrylic Pen Blanks

These acrylic pen blanks are made from cast thermoset polyester plastic resin. This durable material is non-toxic and is perfect for pen making on a lathe.

Polyester acrylic pen blanks are made from polyester, a type of hard plastic. Polyester acrylic pen blanks are easy to drill and turn and produce a durable beautiful finish that will make your pens look professional. From our large range of acrylic pen blanks your creativity in pen making is virtually limitless. Choose from bars of solid colour to ribbons, swirls, eddies and crush and add a whole new dimension to your pen making.

Turning Polyester Acrylic Pen Blanks

Acrylic pen blanks are relatively easy to turn and achieving a top finish is quicker and easier than with other pen blanks.

Start turning your acrylic pen blank in the same way as you would with wood pen blanks - after drilling the blank and gluing-in the pen tube, use a roughing or spindle gauge to turn the acrylic pen blank to round. Continue turning in this way until you have the right profile and the diameter of your turned acrylic pen blank is a few milimetres bigger than your pen bushings. Once your acrylic pen blank reaches round, you should start to see long ribbons of acrylic peeling off as you turn. Keep clearing these away as they often become wrapped around the turning piece.

Use a less aggressive turning tool such as a skew chisel to turn your acrylic pen blank down to the bushings.

Finishing Polyester Acrylic Pen Blanks

Your goal is to obtain a glass like finish on your acrylic pen blank. Follow these steps to achieve this.

With the lathe spinning, sand your acrylic pen blank starting with approximately 200 grit sandpaper through to around 600 grit. Whilst sanding, stop the lathe regularly to wipe off the sanding dust from the acrylic pen blank. A build of of this dust will create friction causing your acrylic pen blank to become hot and may result in some of the dust melting onto your blank, a situation which you should try to avoid. Whilst sanding, move the sandpaper over the blank continuously and do not sand on one spot for any length of time as this may also cause overheating.

After sanding to 600 grit, you may continue to sand using wet sandpaper or micromesh up to very fine grit levels.

Either as an alternative or in addition to fine sanding, you may then use an abrasive powder that comes in bars such as tripoli or white diamond bars to obtain a finer finish. Apply the bar to the acrylic pen blank while the lathe is spinning and then use cloth or paper towel to rub the abrasive on the acrylic pen blank.

A fine rubbing compound, diamond paste or plastic polish may then be used to achieve the final finish.

Some pen makers use a buffing wheel with such rubbing compound, diamond paste or plastic polish to rub off any fine circular rings that may be present on the acrylic pen blank by rubbing the blank longitudinally on the buffing wheel.

Your acrylic pen blank should now have a high gloss, glassy-like appearance and may now be used to assemble your pen.
