Nikkormat EL view-screen cleaning

[johnbear]

Has anyone performed a view-screen clean as part of a mirror damper replacement procedure as described here? - www.kyphoto.com/classics/seal/Nikon_EL.pdf


I was just wondering how fiddly you found it? It's that spring removal/replacement that bothers me slightly. Springs can be extremely uncooperative.

I recently acquired an EL off Evil Bay for £8.50 - details here.

Johnbear i never did this procedure on a nikkormat but i did replace the focussing screen on my D300 by a cats eye type. The procedure is very similar to what is described in the pdf. It gave me HELL even though i thought i was well prepared to take up the job things went very wrong when the spring came out of it hinges and i didn't know how exactly i could get it back in again. finally after half a day of fiddeling and sweating in anxiety to get the d300 back toghether again i succeeded, but there was more dust on the screen than ever before. i left it that way as i didn't want to go through the procedure once more. I now am able to decently focus MF lenses on the D300 even though the focussing screen is somewhat dusty.
With a £8.50 camera i can imagine the procedure will be a little less stressfull in the event of something going wrong.
Anyway £8.50 seems like a good deal on the EL i've got a few but never found one in that price range.

F***ing springs. I hate them.

Here's something I posted to an airgun forum years ago. It's a little long - - 

You probably think of springs as inanimate objects, little pieces of steel, without any life or personality. Well, maybe so. But they seem to be possessed by mischievous spirits whose favorite game is hide and seek. They hide, I look for them.



Have you noticed that when you disassemble something which contains springs, at least one of them attempts to escape - especially the first time you work on a particular item, and you don't have any instructions to follow, so you don't know where the springs are, or which ones are most likely to fly across the room? Have you noticed that once they get away, they always find some place to hide? They never come to rest in plain view. It's always under something, or behind something, or (my personal favorite) in a box of junk in the corner of the workshop.



Had a really good one last night. It got out of a pistol without me seeing it go. Naturally, this was a gun I had never been into before, and I don't have any papers on it, so I didn't even know I was playing hide and seek. At least not until the gun was reassembled and wouldn't work right. A missing spring was the first thing I suspected, but I couldn't find one anywhere. Maybe I put it together wrong, I thought, as I wiggled every little part, trying to be sure I understood how it was supposed to work. Well, I couldn't see any other way it could go together, but my eyes kept returning to those two little projections that look exactly like a spring should go between them. And if I just pushed one of them while cocking the gun, it worked fine. Had to be a spring. After another 20 minutes of crawling around on the floor, and looking under and behind everything, I gave up for the night and went to bed.



What do you think I found this morning on my way back into the shop - in a spot that can't be seen from inside the shop, where you would never look while coming out of the shop, where it can only be seen while walking toward the shop, and only if you happen to look right at it, and the sunlight is coming in the window at the right angle?
