Making progress with my weird RB67.

Ok, I found out what you guys were talking about with the question I had
earlier about my multi-exposure thing not working on my camera. This
weekend I did a light seal repair job on the thing and with the exception of
those grooves by the pressure plate, I guess I'm done. I didn't do those
because I'm not sure they are supposed to have anything in them, but
according to this page, I guess they are.

So anyway, last night I tested my work by putting the lense on "T" and
shinning a flashlight in the lense in a dark room. I didn't see any light
leaks. Then I was playing with it and with the back in the vertical
position I couldn't trip the shutter. I looked in the manual and on the
last page it said that you have to have film in it. I had an old roll of
practice 120 film so I put that in and sure enough it works, but only in the
vertical position. When I turn it to horizontal, I can wind the shutter and
trip the film all the time. So now I'm stumped. I looked at the pins and
all the connections but nothing is bent or seems to not work. This has me
puzzled.

So my questions are, do you...
1. Agree with the pictures in the above webpage that show light leak
material in those tiny grooves by the pressure plate? And wouldn't that
prevent the pressure plate from sitting correctly so that it would throw off
the focus?

2. Do you have any idea why my camera's multi-exposure prevention works with
the back in the portrait position and not in the landscape position?

Any help is certainly appreciated. Ric in Wisconsin.

1. Yes there is seal material in the grooves near the pressure plate. The
groove goes all around the back but the seal stop where will be aligned the
hinge on one side and door lock on the other side.

2. The back is working the same in both positions. The right (bottom in
portrait) hole is the multi-exposure prevention, and the left (top in
portrait) hole is use to indicate that the frame is exposed.



Remove the back, and as you press the shutter release, a pin is coming out
at the right top (right bottom in portrait).



Remove the rotary plate, and as you press the shutter release a pin is
coming out at the right bottom. If you enter a paper clip in the middle of
the right side the pin will now come at the right top. Look at the rotary
plate and you will see the pin that goes where you put the paper clip. It
lock/unlock as you turn the rotary plate.



But you are probably confused by now.



I could send you a video if you want.

I also have two backs to reseal when I find some free time.

Where you able to follow my answer for the second question?

Michel: It looks pretty easy to understand. I haven't looked at the camera
yet but will see what I come up with when I do. Ric.
