white corian

Hi Mt

Black Markings can be removed with (rubbing alchol or light sanding 220 grit) Ive also used counter top magic and Glass stove top cleaner (The Gritty Stuff kinda like Sand Soap) If you can see the Mill Marks in it you are better of to sand with 220 grit until smooth (flat) as you will see lines when backlit. Pretty hard to sand after its carved. Without hitting carve..
Good luck carving !!!!

Did you buy a whole sheet?? Or peices .
Where Did you find ?and if you dont mind me asking cost??
Thank You

Hello Dave,

Got the Corian sheets from ebay.

I purchased 12 sheets (1/4" x 11.75 x 13.5) of Glacier White Corian for $51.50 including shipping.

Also bought 9 sheets of Cameo White and 9 sheets of Bone White (1/4" x 8.25" x 30"). These 18 sheets cost $170.00 including shipping.

Nice job with the back light corian, photos look gastly carved in wood but return to their proper representation once used to filter light.
now that I have a few pieces I will try one.
I made many light box's for photo's and slot machine belly glass (another hobby) and I use lights of America 8 watt florescent bulbs. they stay cool behind enclosures. About $22 for a 3 pack.

G-Man, you've brought up a great interest. Do you sell the light boxes you make? If not, can you show us a picture of what they look light? Thanks, Pam

I do sell on Ebay the billiards one. not to profitable so knock yourselves out. I make the frames using Stile and rail set and cut the lip off to get the plastic in. Kreg pocket holes and screws to assemble.
Lights of America, under cabinet lights, linkable, I get mine in 3 pack from local Meijer, about $22 for three pack.

Hey G Man,
What size and type of wood do you use to make your light box frames?

Doc,

When I got the good results the front surface was carved and the backlight was applied to the flat rear surface. I am still trying to understand the reason for the double inversion. I think that changing the original RGB file to a Grayscale (GS) file and importing that into designer should work and eliminate the two invert steps. However, there may be some underlying technical reason for inverting in photoshop, importing into designer and then inverting again that I do not understand. Just learning more about the technique.

I have been reading, trying to get a feel for doing a photo, etc on any form of plastic, etc. I think the picture inversion is because he carved on the reverse side of what he is viewing thus, giving him a smooth front surface and the image "off in the distance", then backlit. I don't think a double invert is needed. One or the other if you carve so the front remains smooth. I'm still cautious ...... I'll take the plunge soon ... more reading to do.

G-Man, How about a quote on lightboxes for 8X10 corian. I'm going to market the carvings in Corian in my area and I sure could use a good source for them?
By the way, what is the Stiles set you are talking about. Is it ready made? How do you hook up the lights? Have you got a picture of one that I could see?

Oh, I forgot, I can always look on e-bay. Not to worry, I don't want to build light boxes. HA! Pam

Hey G Man,
What size and type of wood do you use to make your light box frames?

I have used oak, MDF and Aspen for the frames. 3/4" frame and 1/2" for the light box's. any wood will work, just depends what your finished project will be. I had request for inexpensive paint grade box's so a 4x8 sheet of 3/4" MDF will make a pile of frames, a big plus is after sanding the glue seams disappear in the MDF.
One thing to consider when making the light box's is what light source your using then be sure to design around it so you can fit it in your box.

I made a couple of Lithophanes out of 6x8x 1/4" Corian. The carved image measured 5x7". For the frame I used 3/4" Oak. I used a carve region of 6x8 with a depth of 0.250 inches. I then used a cut path for the picture window set at 5x7".

As for the lighting, using an incandecent light bulb produces a hot spot behind the Lithophane. The best lighting to use is fluorescent. It does not produce a hot spot and does not produce much heat.

I found a puck type fluorescent light fixture that was small enough to fit in the light box. It is manufactured by a company called Feit Electric. It is a 9 watt flurescent light. The housing measures 3 inch in diameter and a depth of 1 1/2 inches. It comes with a 5 ft electrical cord that has an on/off switch. If you have a large project, you can daisy chain three lights together.

The prices vary depending on where you find them. The cheapest price that I have found was on Walgreens.com The have them listed at $9.99 each for the single light fixture.

I have contacted the company that produces the lights. I was told that you are required to have a resale license. I was also told that the minumum order required is a "master case". A "master case" is 144 lights. The price from the manufacturer is $5.99 each.
