Topic tags/keywords: woodturning acrylic finishing pens

Hey all,

I have a customer that wants 9 pens in an acrylic that matches her school colors. Being a woodophile I have not yet turned acrylic. I understand that the tools need to be very sharp so I hit the Tormek and went to town. It was fun to turn and then I realized that I haven’t figured out how to finish them yet. I did some research and found a source for acrylic sanding pads up to 12000 grit. Does anyone add any finish to this mix or is sanding to 12k enough. Coming from traditional wood turning I feel obligated to add something for protection, but I guess this isn’t necessary. Just looking for some reassurance since this is for a customer.

You might pick up some canopy polish from your local civil airport or from an on line aircraft supply house

I can’t see why some EEE cutting paste & shellawak would not work but have not turned acrylic.

the acrylic sanding pads should give you everything you need.
I think there is some plastic polish out there that can be used as well. I haven’t done many acrylics do I don’t have all the details. The few i have made were only sanded to 220 grit and then hit with 0000 steel wool.

I have used car wax with good results.

also I always wet sand acrylic and have the micro mesh sanding pads. Like you I seem to always want to polish, but it’s not needed.

I have been told to sand up to a high grit… 1200 or so then finish with plastic polish or some folks use CA glue….

I have done several, and if you polish to 12000 at high speed, with a light touch, nothing else is needed.

Have your say...
