How to frag a bubble coral

[jmesmcm]

I was wondering on the best way to frag my bubble coral as it has gotten to large for the space it is in and is hitting the rock when it fully expands. I was thinking of trying to cut in half using a dremel but am worried about killing it as I have been told that they can be difficult to successfully frag. HAs any one fragged their bubble and if so how did you do it and was did both halves live?

bubbles are one of the hardest corals to frag. ir requires seperating the skeleton ever so slowly... and sort of streatching it apart... some are sucsessful others are not... actually most are not sucsessful...
