Thread: newbie question

    newbie question

    Hi All, I am primarily a cabinetmaker with a cnc router and was asked to build a sign for a local Historical Society in my town. After having taken one of Keith's ADA corian weekends, I am a believer in using corian, vcarving the letters and self painting. However this sign will hang on an existing wooden post and will be two sided. the sign dimensions will be 24 X 30. The concern is the weight if 2 pieces of laminated 1/2 corian. what do you professionals think. thanks in advance, Brian

    Are you going so deep that you couldn't letter two sides of one thickness of 1/2"? If so, how about 3 pieces of 1/4" instead? That would save 25% in weight and should still give you plenty of thickness to engrave.

    Brian,

    You can VCarve both sides of a single thickness Corian sign as long as your carving isn't too deep. When I need wide carving I use a 90 degree bit so I don't have to go very deep.

    Plus you can cut out some letters and apply.... Making it more 3D.

    90 or 120? 90 degrees on a double sided sign of 12mm is only going to get you about a 7/16" wide letter. That's pretty narrow when doing a large sign.

    If you are stuck on 1 piece and thin material, I'd follow Al's advice and make some prismatic letters and apply them to the sign.

    Don't forget about the flat bottom V90 Bits too...

    I use a font called modern that is a Single Stroke that I use the Outline Mode to cut. I only use a .1 deep but a 3/8 end mill makes nice 2.25 inch high letters. The bigger the letters the bigger the bit needs to be... for me it emulates the plastic router guide letters.

    Hi Guys,
    what I ended up doing was running the toolpaths with a flat bottom (.175 inches deep) and V grooving with a 90 degress bit and was happy with the result. I plan to show the customer before running the sign.
