Doesn't the "point of aim" for the 2 taking lenses have to be the same? Would you need a mount that allowed adjustment? Or camera bodies with a high degree of specimen-to-specimen uniformity to allow a fixed mount?
There are (or were) Y style cable releases. But years ago for a project I took 2 identical releases, mounted them on either side of a small piece of wood with tape. I carved out a small indentation on both sides of the wood to hold the collar of the cable release in place. I was able to actuate both releases at once.
Yes, it's ideal to get them aligned well, although small deviations could be corrected while cropping to set stereo window. It's more important that the focal lengths are a good match so that the images are the same size.
There are plans for a dual cable release at http://www.berezin.com/3d/dual_cable_release.htm.
Here's someone who took off the focusing knob and spool knobs and coupled two Rolleicords together-
An interesting 6x14 camera on his site, also.
Rollei made a stereo camera in the '50s, I believe. A search will find more info.
Unfortunately, the only affordable options are the Holga with its low quality lenses or the Sputnik with better lenses, but still some major quality issues. I've contemplated hacking a stereo holga and adding some better lenses, but want to know if there are suitable mf cameras for twinning.

there was a stereo-makina http://www.ebay.de/itm/Plaubel-Stere...item35c2352029
speaking in diy terms, a polaroid 4x5 passport camera would be a good and inexpensive base to start with.
Interesting! Sam Smith used to have a site full of stereo hacking projects, but it's long gone. Alan Lewis still has a few pages up with similar projects - http://www.seriousviewers.com/projec...1/cameras1.htm - http://www.seriousviewers.com/projec...2/cameras2.htm - http://www.seriousviewers.com/projects/mfcam2/mfcam.htm - http://www.seriousviewers.com/mfcam1/mfcam.html

There are also hacking projects out there like the Frankenpony and the Argus See3D, but the are all 35mm.
