Mike,
I will phone you tonite and explain how to do it, you actually need to sand or grind away part of the secondary holder. When you remove the secondary from the scope, you lay the scope towards horizontal so that if you drop something, it doesnt hit the primary. You then undo the centre bolt holding the secondary holder only, you dont move anything else, this way your secondary collimation won't change much.
