Working on F2 DP-1 Finder

Working on the Nikon F2 Photomic finder is more tedious than working on a shutter. That's about all the steam I've got in me right now after FINALLY getting the pulley back on right. Thank God for this link, although I must say it understates how hard the process actually is. http://www.google.com/url?sa=t&rct=...=AhGhic55TA6R3OWZzdCHfQ&bvm=bv.67229260,d.cWc

Maybe I'll come back and elaborate on the work I've done, I don't know. I'm pretty well drained on this job presently. If you have it in mind to work on one of these things, you better be a pretty darn good tech, or you're going to have something to throw in the garbagecan.

I thought I'd inform the forum how the job turned out. I followed the instructions carefully as layed out in the above link and the job turned out nicely. Of course it's nighttime now, so all I can do is run around the house looking for things to meter with the camera, my Sekonic, and my Luna-Pro SBC, and not even the 2 meters can agree. But the camera meter is in the same ballpark with the 2 meters. After the reassembly of the DP1 and initial burn test, I proceeded with calibration of the DP1 as best as incandescent and flourescent light sources allow. Tomorrow I can use the proper daylight color temperature to dial it in.
All in all I did a very good job. The original problem was jumpiness of the needle, so I had to get all the brushes and wheels out of the head for cleaning. Jumpiness is gone. This was my first photomic head, and it was tough. Some times I was sure was the end of it. Beware, this is not an easy job and most of those parts are smaller than a germ's hair.

i'll be keeping an eye on you sover's uniqueness always worried me a bit

Hi Tom

Thanks for link.

Well, after an hour or so of indoor/outdoor testing amongst all the gadgets I mentioned above, with a gray scale on a lightstand, this DP1 project turned out beautifully. I seem to have good linearity from EV2 to EV18. Did not test below EV2 because that's just too dim of a lighting condition to see all these dials very well.
All jumpiness and erratic behavior of the meter needle is gone. I do believe this is one of my better jobs. (I always say that, because it's always true).
Remember, there is no excuse for poor work when fixing these gadgets. Get your problems and procedural questions worked out before opening up the device, because there will undoubtedly be enough surprises to deal with once you're in the middle of the job.
Doing good work is hard. Especially for knucklehead-boobs like me.
And remember, if I can do it, you can do it.

maybe Tom maybe.

I need to check the foam in both of mine and have destroyed a screw driver on the 1st fastener.
