Does anyone make lithos from 1/8" material? It seems 1/4" and 1/2" is the norm. Here is one I made with 1/8" ivory cast acrylic. It seems to look just fine in natural light. A little more precision with carving depth is required but I see no need for a light box.

I have never done one but that looks really nice.

Good to know! I have done them on pvc and turned out ok. I found a source for 4' x 4' x 1/8" for $40 just haven't been able to make the trek to get it.
It seemed to me that 1/8 should be the norm since .10 is the max carve depth per pass recommended for acrylic.
is that with 1/32 bit?

Well done litho, Dan. I haven't ever used 1/8" material, but will keep an eye out for it to give it a try. Very nice detail in your carve....

The 1/32 bit is to me the only way to do litho's

Detail !!!!

I agree with Robert. The 1/32" is the only way to go....

Was that a 1/32 carving bit or cutting bit

were you get it from carvewright I see they have it there I like the ideal of 1/8 litho

Actually, I used a 1/32" ball nose bit. I carved the litho in two passes. First pass with a 1/16" carving bit and the a "skim" pass with the 1/32" ball nose. I am sure you would get the same result by just using the CW 1/32" bit.

I do not have the CW 1/32" bit. I had a 1/32" carving bit I bought from www.soigeneris.com (http://www.soigeneris.com) but I just noticed it broke two of the three cutting edges off of the tip the first time I used it on some oak.

I have a stock pile of 1/16" and 1/32" two flute and four flute 1/8" shank ball nose bits with only about 1/8" LOC that I use in an ER11M adapter.

What was the total dept you carved the 1/8" litho at ?

I am going to get a sheet of it.
Would like to do a couple for the conference to display with the ones
in 1/4"

Since the 1/32 bit has come out that is all I use for the litho's
Great detail with it.

I have one in the machine and four in the bit draw.

You could say I am quite taken by the 1/32 bit

The depth was 1.1. The shiny spot in the hair turned out a bit thin. The ideal is to cut it close and maximize contrast. Wide white areas like the shiny spot are not good.

I fear breaking a 1/32" carving bit. Have you chipped any yet?

I have in countered the shiny spots.

I had to ad just the dept and go again

you have 1.1. Am I missing something??

OK. Will have a sheet of 1/8" Tuesday to do some litho's on
Will carve the same subject matter on the 1/4" and the 1/8" and have them side by side for
viewing at the conference.
Will post them as soon as I get them carved.
