This is what I was hoping. I could still indent a thumb this morning and that was 8 hours, so another 8 might not be too bad. At least it will be a learning experience whatever happensHopefully, you will be able to cut it. Vinegar soap can get really hard really fast. But since I do not make Castille soap often I am no help there, and the OO might save you since it sets up slowly.
Actually, after reading a bunch more today, I'm not worried about it being too hard, but am worried that it will be too soft. Apparently back in December we had some soapers here trying CA with vinegar and it did not go well. I will have a very interesting update in a couple of days if it does harden...because it will point a little bit as to what causes this problem when using both acids.
