I haven't used my Crown in a while and I noticed that the rangfinder is off. I have the Graflex Top Mounted Range Finder with the correct cam. The rangfinder is out of alignment (top and bottom) and I figured while I'm adjusting that I'd check infinty too. How can I do this?

Take the top of the RF off and you should see a set screw that adjusts the tilt axis of the far mirror.

As for inf check, set the camera up on something about a 1/2 mile a way. A street lamp is good. Set everything as though you think it should work and check the ground glass with an 8x loupe. To proove it's right on, loosen the front standard and push pull it, leaving the rails at RF inf. Check the ground glass for sharp infinity and lock the standard down and see if the inf. stops are where they are suposed to be.
