I finally got around to getting a mirror, and oidnt the hole in the mirror trick, align my d2. I had used a level in the past, but with the mirror it was still out quite a bit. The negative stage was easy. The problem, and my question, is how on earth do you adjust the lens boards? My 4X5 lens, on a long cone is out a little, but my shorter cone and 80mm lens are out a lot, in different directions. If they had just made the cones mount with three threaded screws instead of just two, it would make it easy. So what do you all do? I did a search, and couldn't find anyhting addressing the lens board, except in general terms.
