I just got my 'NEW' 2nd-hand Grandagon today, which is being mounted on a Sinar board. Fair enough. So I screw the front cell off the shutter. Simple. And then, when I do the rear cell, I felt some resistance come and go about three times and then it stuck there. So I use more force to screw this thing off. And there the rear cell goes off without its screw ring!!!!

The ring is STILL stuck on the shutte!!!





NOW NOW HOW COULD I GET THIS THING OFF!! AND MOUNT ON MY SPEED GRAPHIC!!?????

I THOUGHT RODENSTOCK COULD DO BETTER THAN THIS!!!

ANY COMMENTS WILL BE WELCOME. i AM NEW TO HERE AND NEW TO LF AS WELL. :P

MANY THANKS
