If I know anything about helicoids, it's that you don't take them apart without paying close attention and marking the starting points. Now I know why they say to do that. The shutter came out pretty easily and I tightened the loose screws at the focus ring but it kept binding at about the 5 foot mark so I took out the screws and removed the focus ring. While I was messing around twisting the helix back and forth to see if some cleaning and lubrication might be needed, it came apart. Several hours later, I've got the camera back together and the focus ring is nice and smooth but I seem to have disabled the rangefinder in the process so I guess I'll be pulling it back apart again. Any tips on the re-collimation procedure?
