Its actually pretty easy eh? What did you use? I've been using an Inland diamond bandsaw. I've cut this one 4 times now.
Here are two freshly cut halves.
Here is one of the pieces fully healed a while later.
And here is a little piece that accidently broke off and formed a mini colony. Red arrow points towards a pod to show scale.
I just cut this one a few days ago. Picture is from right after cutting. I'll take a picture in a few weeks when it has healed fully and looks like normal again.
