    Building a Punch to Make Properly Perforated 828 Film

    All -
    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.

    Thanks!

    Nice article Matthew, and welcome to APUG.

    I hope this works out for you and thus for the 828 users out there ... you're obviously an ingenious and methodical worker, and I particularly like that you have released your design into the wild a la GPL

    I might be interested in some 828 film. As for where to get unperforated 35mm, I'd email Ilford.

    You could slit down 120 or 127 film.

    if you read the linked blog post, slitting 120 is the next preferred option if unperf 135 can't be easily found.

    Thanks for the feedback! I have sent a message to Ilford asking if they can supply unperforated 35mm stock. We will see what they say. Stay tuned.

    I bought 2 rolls of this to try in 35mm cameras.

    Thanks for the link. I bought a roll for my Bantam Special. Just need to figure out how to expose/develop now. I'm guessing ISO 12 or 25?

    I've also purchased microfilm on ebay. Just search APUG for information on using microfilm for pictorial use - it can be slow and have very high contrast.

    Here is a similar thread about punching film:
