I am rebuilding a previousely written off Rolleiflex MX-EVS and this thing is just driving me nuts. I keep breaking the very soft brass screw that was on it. What is worse is that I found out they were all Whitworth thread.
Having been brought up with Metric I am completely tearing out my hair on specifying the thread size. I have checked the repair manual but they only give a description and not the tread.
Can anyone help me to check if I have got them right?
Hood screw : 1/16"x5/32"
Rolleifix screw: 3/32"x5/32"
retaining Screw shutter speed select wheel: seems to be M1.5x3mm, but I am not sure as I cannot figure this one out.
