In this video I will show how it's possible to repair an old Sinar DB automatic Copal shutter, that have problems with the slow gear, and way too long exposure time from 1/30 second and up till 8. second.
And also another issues with the weak main spring, that I actually cut a little shorter so the tension was fine again, and the shutter works again as it should.
I have no (0) idea where to get spare parts, so this was the way I fix it, and it work's :-)
