I am in the process reworking my S.G. The focal plane shutter was dissambled when I got the camera. I reinstalled the parts and the shutter sort-of works. The curtain is in near mind condition but I need to know the proper install and adjustment procedure. Thanks to everyone in advance.

Go to http://www.southbristolviews.com
At the bottom of the left side menu is Graflex Manuals. The service manual should help.
If you need more help, or if you have a different camera, there's people here who should be able to offer good advice and even do the work...
