More info

These acrylic rods are made by casting thermoset polyester plastic resin in tubes and reproduce the beauty of some of the worlds finest gemstones and organic treasures. This durable material is non-toxic and is perfect for pen making on a lathe and can be turned into breathtaking works of art. Polyester blanks are safe for drilling and turning on a wood lathe provided the tools are sharp.

Turning Polyester can be difficult if you are using it for the first time.

Some notes on turning Polyester:

  • Use very sharp tools and gentle light cuts are needed to keep chipping to a minimum.
  • A negative-rake scraper produces the cleanest chip-free finish followed closely by a skew chisel used as a scraper. A regular scraper has a tendency to create small chips. 
  • It is important to engage the tool on the rest, rub the bevel and slowly lift until cutting starts every time. Acrylics are unforgiving of careless cutting
