Lithophane test in acrylic

[laconcepts]

So I decided to try a litho on our Fadal under flood coolant.
I followed along with the tutorials and User Group instructions.
Since I do not have a ball endmill I used the 1/4" 60 degree onsrud V bit that I have on hand.
The finish pass rastered at 315 deg and cut perfect. The machined surface is as clear as the unmachined. I will post pics tomorrow of the machined surface.
Im cutting 3 separate Marylin images and will test different surface finishing ideas to make the translucent.
The cool thing was how the coolant settled in the relief creating the image. It drew a crowd in the shop just checking that out.
More to come and thanks for looking.
