I was resawing a 6/4 , 8 inch wide mahogany board , removing a 1/4″ of material.(this board was prepared on a jointer and planer and was dead flat). After resawing, the board developed a very bad bow. Did I do something wrong? Can this be prevented? I cut three other boards the same way without any problem. I was forced to get rid of an expensive piece of mahogany.

Perio,
By "bow" I assume you mean end-to-end. I suspect that the wood was not evenly dried or acclimated to your shop environment. If you are resawing to use over a substrate then all may not be lost, depending on the final application.

There are ways of fixing bad bows. I have in the past taken boards that I am after resawing and laid them out on the lawn for a short bit. The moist grass will help he board lay flat again. I have done this on wide planks and it worked great. Once smoe what flattened then I sticker it and dry it again with some weight on it to help it from bowing again.
By the sounds of it you have have not had a evenly dried board to start with.
