Paul, just remove the screw and use the grub screws as I described. At very least this will show whether you can reach focus or not but it is actually a perfectly valid way of using it.

I had totally forgot just adjusted the three grub screws so it will hold the BST`s even upside down and can change them. I now have another centimetre of inward travel probably enough for a 4 mm. I will try one in November when I go to the meet with Nick. Thank you Stu that has turned out brilliant.
