I am fairly new to the hobby, and the forums, so forgive me if I'm retreading old information. I have searched for this information exhaustively and not found a lot of help.

I made my hilt body out of 1 inch inner diameter PVC piping. I want to use the MHS heat sink assemblies but only now am seeing that they may not fit. I might have to get creative and bore the tubes out or replace sections of them to accommodate larger parts, or, worst case scenario, rebuild them with a larger base pipe. What is the OD of the heat sink assembly sold at the Custom Saber Shop and can I rig up an alternative to fit a 1 inch ID pipe?
