Bit if a funny request this, not sure how to describe it...
I've got a late Werra 1, the model with the little plastic grips on the speed ring and the aperture ring. Those on the latter are OK, but the ones on the speed ring have completely broken off. Al that is left is the hole they originally seated into, which is flush with the surface of the ring. While I can change speeds, it is a real pain in the backside.
I've wracked my brains, and can't think of a sensible substitute. Any ideas would be greatly appreciated!
Thanks,
Adrian |

I'm not familiar with the pieces in question, I don't know how big they are or how they are attached. I once replaced a broken focusing button on a Graflex Graphic 35 by cutting a couple of pieces of black, 1/8" thick ABS plastic sheet, bonding them together with solvent (MEK, methylene chloride or "Weld-On" - acetone can be used in a pinch), and then shaping the piece with files. ABS can be drilled and tapped if your parts are held on with screws. |

Hi Rick,
I can't be certain without a complete one to hand, but I reckon they were about 3mm x 6mm, with a pin at one end that fits into a hole in the ring. They are not easy to find a picture of - even this site doesn't have a good pic - in fact, one of theirs looks to be missing the grips too! Obviously a retrograde step from the earlier metal grips. http://pagesperso-orange.fr/krg/werra/werra.htm
On the other hand, you've given me food for thought - I reckon I can probably put a pin through something thermoplastic, cut/file that to a not-too-ugly shape then attach it via the pin.
Thanks, Rick - that extra kick to my thought process is much appreciated!

that's much smaller than i had been envisioning! i was thinking of something more like the plastic grips on some of the Contaflexes.
For a source of ABS to carve, you could pick up an old dial telephone at a junk shop, their housings were good quality ABS. Or for a bit of poetic justice, an old P&S camera: the better ones would probably be polycarbonate, the cheap junkers more likely ABS or maybe even high impact styrene.... any of those materials should be workable. |

If you could make a ring of a transparent plastic that would allow you to read the shutter speeds and embed pins through it might be strong enough. A nice camera, I'm sorry I sold mine. |

Now that is off the wall, Charlie! I wonder, though, if a bottleneck and two pins of some kind might make a temporary fix. Hmmm... Must think about it!
Yes, I have sadly broken more Werras than I've fixed, but I'm learning!
