Rolleicord II Compur Shutter

[Greg Heath]

I was wondering why my Rolleicord II Compur shutter would not stay on speed. Disassembled it this morning and lo and behold the Shutter spring in the timing escapement is broken. One teeny tiny part wound around a spindle has made my Camera into a big paperweight. I have check *bay, and found some replacement cameras, but anyone have a Rolleicord Compur Shutter laying around I could use?

Not that this camera is a wonderful gem, but I restored it from scratch. I hate to see it not ever get used.

I could try to remake the old part. Maybe I can use an old watch spring. Any ideas you have may help.

Maybe look for old folders with a Compur shutter and pull the part(s)? I know that the Compur Rapid off of Voigtlander Bessa 66's and a Zeiss with a 75mm lens are the same shutter size as in Rollei.

If it's a spring inside the escapement movement, my understanding is that its tension is set at the factory and that doing a replacement is tricky. Just swap a whole unit from another shutter.

Shutter escapement springs are similar to watch mainsprings. New one's can be made, you just have to find a talented and interested repair person.

Out of curiosity is it like this link below with a "conventional" main spring and a watch-type booster for 1/500?

nope that IS the booster spring. But the wrong one. That one works great. I have Rick's Camera schematics too. Lots of good stuff in there.

Here is the Shutter timing Escapement. The spring is definately broken. I might try to rewind it and super glue it to the Outside Holder. The original was secured on the inside of the escapement. The little indentation on the outside of the clip is where the worker pinched the metal. I will secure it to that point. That white bunch of cotton on the right, its the head of a Q-Tip. I love working over a magnifying glass

Regarding glue, check out this site that someone posted in another group that I hang out in:

The guys that run it are hilarious (but know their stuff, too!)

Thanks for the link. I will try to JB Weld. I have used it before. I will have to file the part before connection. I have also been looking for an extra escapment. Seems like prices for parts cameras have jumped over the past few years. Seems that "parts" cameras are collectible now too ! The shutter might be slightly off in speed but pretty close. I think thats all i can hope for. Even a new old escapement could also be off slightly. Even with the spring broken, the shutter still fires at the higher speeds.

I take those escapements apart to clean them in my Bessamatics and that spring is retained by inserting the free end into a slot on the capstan.Your shutter is larger than mine I think but that is what I expect to see when I reassemble them.The capstan is split from the top down on my cameras.Ron G

I appreciate the info. I might give it a go tonight. Gluing it would definitely be a kludge to say the least. I need a better magnification to see the part. I work through a magnified fluorescent circular magnifier but need something better. What do you use. Greg
