I just noticed that a color extender's width is almost EXACTLY the inner diameter of a choke piece.

As it sits right now, there doesn't seem to be any metal from the board touching the aluminum, but I'd still worry about shorts. Maybe some 3/4" blade material to isolate the board from the aluminum?

Has anyone ever done this? How would you secure such a setup? I'm planning a saber, and this would really save me some space.
