We have always made our chnl ltrs with Cast Acrylic but because it seems to be getting harder to find the sheets that fit our router table I was wondering if anyone has or is using Extruded Acrylic as an alternative. From what I've read about Extruded it seems a person would be able to use extruded in smaller letters of 10"-12" or so without as much distortion. Anyone have any experience trying extruded Acrylic for chnl ltrs?
