Here's my first go at a lithophane... simple picture of an EC-130H in 1/4 corian. I used the best setting and centerline text for the text/patch. After carving, the centerline text part was too shallow to show light through (and was uneven in places) so I taped off the c'line portion and spray painted it with Air Force Blue spray paint (enamel), waited 20 mins or so, and then scraped the paint off with a VERY sharp chisel. This left a very clean surface around the painted letters. I then baked (with LOML's dubious permission) the piece in the oven at 350 for about 11 mins and shaped it on a form made from a home depot bucket. I still need to make the stand, but that will have to wait till this weekend. The last pic makes it look like the litho is warped, but that is just barreling from the camera (though the litho is non-concentric from the bucket, it is evenly non-concentric)
Thanks for looking,
Lawrence
