Hello,
I have just finished a complete disassembly, clean, and rebuild, of a Graphex #3 shutter with the help of the Graflex Repair Manual. The shutter now works wonderfully except for one remaining issue:
Normally, the end of the main lever is supposed to hit the blade lever to open the shutter blades, and this is what happens when the synchronizer is set to any position (F-X, red-M, black-M) except "off". The problem arises with the flash synchronizer set to "off". The main lever just skims the blade lever, and the blades barely open at all. This happens on all speeds. Speeds are otherwise correct with all synchronizer settings.
If I trip the shutter with the synchronizer set to "off", while holding the cocking lever, and slowly let the shutter release, the main lever contacts the blade lever just fine.
It seems that with the synchronizer set to "off" the main lever moves too fast and it doesn't drop quick enough from the release lever to fully hit the blade lever. With the synchronizer engaged, there is just enough extra drag on the main lever for it to drop and hit the blade lever fully.
Has anybody ever run into this and found a solution? Obviously, the easiest solution, which I'll do for now, is to just leave the synchronizer on the "F-X" setting and use the shutter normally.
Thanks for any help you can offer.
