I get the material from a local plastic supplier, I forgot what the brand or type material it is , but it is used a lot for dash plates on boats . It is not starboard its harder than starboard and a little softer than acylic. From what I understand it is a crosss between the 2. the material that I usually get are drops from the local suppier so it did not have the label on it.It is nice material to cut. I used to use starboard for a lot of bigger dashes until I found this from the supplier..Next trip to the supplier I am going to get the braand name , I have had a few people ask what it is.
I usually cut it at 60 IPM at 10000 RPM..
