Well I had all this 3- inch zebrawood and even more Mahogany of many sizes so I had to find a way to cut and engrave it without it becoming ash, Wet works but only for one pass, so I had to proceed by dampening to the extent possible and very evenly, and then sopping up all that would sop. This tended to keep things even and Zebrawood is actually quite hard and so warping was not a problem. It did take many hours and did not quite go all the way through, so there was a lot more work with a scalpel, files, and sandpaper before I could get a good result and still there are issues.
However, I do like the result but will not be repeating this design in Zebrawood.
