Bought a $12 JIS screwdriver set and it saved a Nikon FE from the parts bin
Got a Nikon FE off a guy in Fresno for $20 because the wind lever was jammed and he said it was dead. I kept fighting it with my old Phillips and chewed up two screw heads, which cost me about an hour of careful filing to fix. Then I dropped $12 on a set of JIS drivers and those little screws came out like butter, no cam out at all. Turned out a bent lever inside was the only problem and the camera shoots fine now. What do you all keep around for the stubborn JIS screws on old Japanese bodies?
