Hi,

stupid question, but I do not have a manual.
How does one set the shutter to "open" on a compound shutter?
I see the shutter trigger, the aperture, shutter exposure dial, and the one that cocks the shutter..
but nothing to open the shutter..
there is a little hole next to the air reservoire, should something go in there?
does this mean I am missing parts?

here are some images:




timings seem okay (I'll have it checked later), and aperture blades are okay as well. specks you see is just dust :smile:
and what does the red triangle mean? uncoated? single coated? multi? something else?

oh wait.. the "missing" part is probably where the cable release goes (I think)..
should I then just open the shutter with the cable release locked????

see, I told you this was a stupid Q..
I found it (thanks to playing around with google keywords)..
it seems the little thingy at the aperture ring is an M/B/T switch.. and this should be used to keep the shutter open for focus..

clever, but not obvious if this is your first compound :smile:

Happy to hear you figured it out :wink:

One note though. As I remember, and I may be wrong, when the shutter is set in B or T, don't try to move the cocking lever. I may be thinking of a different shutter, but I think it's this one. The cocking lever will be "stiff" when at these settings. If you force it, the shutter breaks...

If you do a search, you can find out the info. Sometimes my mind is just someplace else (like work...). But since this shutter is obviously new to you, I didn't want to hear that it broke when you moved the cocking lever...

Good luck with it!

yeah, when I looked for the question above, I found that one as well. cocking the shutter in B/T is a big no-no .. well, shouldn't be too difficult to remember :smile:

Once you have the shot composed, film holder inserted, cock and fire the shutter 2 or 3 times just prior to pulling the darkslide and making the exposure.

Before making the final exposure, be sure to let the shutter settle for a second or two, if you've "exercised" it before hand. If the shutter is in good repair, it shouldn't need it. I recently had one serviced by S. K. Grimes, and they still do a fine job on them, despite Mr. Grimes' passing.

I really like the way these shutters work. They seem to have less vibration than some mechanically timed shutters.
