Steve, you are a gentleman!
Yes, I can see them, excellent photos – and now having seen them I think I will start again and make something a bit better than my current attempt 
Looks like the end of the clamp screw pushes a sprung plate, the same as the other clamp which is a lot better than having the screw marking the 'finger' so I am going to do the same.
I have been busy the last week or two installing electrical ducting around the walls of my 'batcave' so it will be nice to get back to doing something a bit more interesting – I have put up a couple of images of this (in Odds and Sods) if you are interested…)
This is in anticipation of a bit of re-arrangement to make room for the new milling machine…
Best wishes
Chris
