Linhof shutter with no way to attach a cable release. Help please.

fatboy22 · Jun 6, 2019

So I have this Linhof shutter and it has no way to attach a screw in cable release. I have seen devices on several large format lenses that are mounted to the lens boards (little metal blocks) that are tapped to a standard cable release threads. Where can you get something like that? I could probably make one if I knew what thread was of a standard cable release. Anyone know? Any one know the technical term for that hardware? I have searched google and ebay for such devices and have not found anything. I know Linhof makes a quick release device for cable releases but I'm sure its pretty pricey, even if you find one.

Not to be a complete idiot, but are you sure the shutter has no cable release socket? I ask because I've seen Compur shutters -- it is a Compur, isn't it? I mean, Linhof didn't make shutters. -- with a small screw in the cable release socket.

Yes it is a Compur size 00. Dan I know you know a lot about shutters from reading your stuff on Graflex.org. It has nothing but at trip lever, nothing to screw cable release in. The old graflex view camera board I took shutter out of had some kind of permanently a fixed bracket that a shutter release was permanently mounted to the board and somebody soldered a disk on the end of the fixed cable release and that's what tripped shutter. Now I have moved shutter to a Linhof board for my 6x9 Technika camera.

should be easy enough to mount to a lens board, other listings under that search term may work but you'll have to sort through the 35mm stuff.

Thanks for the link!

Alternatively just grab a camera out of the rummage box. Nearly all have that release button with tapered thread, some even a rectangular button, if that seems handy, and fix it (epoxy glue, hotmelt) to your shutter.

As even indicated in that Ebay offer the shutter has to be disassembled before mounting the spare part.
At least that part comes with a rivet, not a screw.

Oh. #00. Modern Compur #00 shutters rarely have cable release sockets and there's no easy way to add one. The suggestion in post #4 above will work but attaches to the shutter, not the board. Now that I think if it, one of my paperweights is a thoroughly destroyed (cracked and chipped internal elements) 90/8 Super Angulon in a #00 Synchro Compur, also in poor condition, with cable release socket. The socket is held in place by two screws whose heads are inside the shutter body.

Two other solutions. #00s in some older folders have cable release sockets. Not mine to reason why. Find one, move the lens' cells to it and make an aperture scale to suit the lens. Or have, for example, skgrimes scale the shutter. I've done all this for a couple of lenses.

The Seiko/Seikosha shutters many Topcor lenses for 6x9 Horseman cameras are in also have no cable release sockets. Horseman boards for these lenses have devices that accept a cable release and push the shutter's release lever. Get one, remove the device and attach it to your board.

By the way, which lens is in the problem shutter? I know that selling or tossing a lens isn't a great pleasure but you might be best off simply replacing the lens with one in a shutter with a cable release socket.

The thread for modern cable releases is 50 tpi tapered 14 degrees, 20 minutes. I don't know where one can get such a tap, or even exactly how to use it. Sometimes a cable release with the tapered thread will work in the old straight thread sockets with a no. 5-44 thread. A 3mm thread is somewhat similar, and may work with the tapered cable release. I haven't done this, but you could check your release against a 3mm nut in a hardware store and see how secure it seems.

The conical tap is available, but at prohibitive price.

Actually the majority of cable release sockets on leaf shutter have a straight threads.

I have a few Compur #00 shutters and all 6 have cable release sockets. However not all Copur #00 or #0 shutters had a release socket instead the release with the socket is on the top body of the camera with a link to the lens. This was common with 120/620 folding cameras.

There was a crossover between Linhof in terms of share holdings in Deckel and many Linhof Compur shutters have better casings etc and minor modifications.

That is interesting as I got non such socket with straight thread myself. But likely you are referring to folder cameras, of which I merely have any.

I think the threads are straight on the cable release sockets of all Compound, Compur, Vario, Pronto, Prontor, Ibso, Ibsor, Seiko, Copal, Epsilon, Trikon, AGI, Lucc, Gitzo and various unnamed leaf shutters I own and that includes TP roller blind shutters and copies (late ones have the release arm tapped). That's forgetting the US made shutters which are the same.

The conical thread even was invented by Gauthier (Prontor Works)

The conical thread typically is called "european" (even by ASA).
The straigt one "american".

You better have a second look.
And I shall think of any straight one I could have got.

I found a release cable with straight thread listed in a Linhof catalog. There is a typing mistake, by that the cable is not related officially to a certan camera model.

However I am quite sure it was meant for the Press 70 / Aero Press.
As there is a hint at these at the catalog and as with these cameras the straight thread, and thus the longer twisting to get it off, makes sense.

Linhof shutter with no way to attach a cable release. Help please.
