Yes, it did look quite nice, hence I am playing with the design.
I used a 16mm bolt and put an 8mm bolt through the center. I think it should be quite rigid when everything is tightened, it give me a better feeling then the mirror cell sitting on a spring. I dont think rcos use this method but I do think astrosib have a similar bolt on thier line of RC's. Here is a picture of the scope I got the idea from, I hope he will not mind.
