What device are you using? Under normal circumstances i never recommend removing, say, the delrin cover on a Reo Grand, but if that's something that will give you better access to the nipple, then so be it. [insert smutty remark about nipple access here]
Usual cautionary note: the screw is finely threaded and it's easy to strip the hole it goes in - do not over tighten it when you re-fit it.
I will look at this a lot more closely before attempting. Trying the angle cutting for now......
Will let you know when/if I've succeeded! OY!
Again, thank you!
Refitting a tube should not be a reason for a Spa visit!
