Can anyone help me disassemble a MR Anakin ROTS LE

[Anakin Starkiller]

So, I bought a MR LE Anakin ROTS lightsaber on e-bay recently that had some damage to it. So I wanted to take it apart and repair some parts. However, I've gotten about half way through disassembling it and have reached an impass. I'm not quite sure how to disassemble it from here on. If anyone know how this piece might come apart, I would apreciate your help. I've posted pics of the saber as is now.

Thanks

Dan
