Thanks Fredxx. I am using the Google groups forum site so not sure why it doesn't quite the text.

Based on your post, am I supposed to cut the sheath such that it is tight between the 2 end points? I cut it with some slack to give me some room in case I needed to move something slightly.

The brass on the fitting is around 2mm thick around the hole the sheath goes into. . The depth of the hole is around 6mm
