I just finished a project which I think would be on interest to this group. I have designed and build a device which will accurately produce 828 film, including the perforations, from unperforated 35mm stock. The resulting strips of film can be re-spooled onto used backing paper and spools to provide an inexpensive and high quality source for this obsolete film.
As a teaser, the device is pictured above. For complete details, and a set of plans, please read my blog post on the project at http://www.dasarodesigns.com/project...ated-828-film/.
What I need now is to find a source for unperforated 35mm B&W film stock (I have already found that I can get unperforated Portra, but I want black and white so that it can be easily developed at home). When I do, I plan sell strips of punched film so that anyone with an expired roll of 828 who is interested in shooting their Kodak Bantam may do so inexpensively. If anyone know who might supply such a thing, please let me know.
