    What happened to the Filminator?

    I have seen that coater, and I know its advantages and limitations.

    Is this a Kodachrome thread? I'm afraid to look.

    All in all, it probably isn't too outrageous for an industrial customer that wants a coater that "just works out of the box" and doesn't want to fool with it. But it is a bit steep for a guy in a hobby market. I certainly have paid more than that for industrial equipment that "just works" although not quite something as simple as this looks.

    But I'll bet something turns up on fleaBay once in a whole lots cheaper.
    Not too bad at all. Remember, the "hobby market" is providing at least some of the demand for $7,000.00 Leicas. If the apocalypse comes a small group could go in on this for a simple B&W emulsion. In the meantime your film needs can be supplied by any of several manufacturers.

    I've never made and coated my own emulsion but it actually looks pretty simple (a wire wrapped rod; how elegant!) How come nobody talks about the sprocket hole puncher? Now that's something the home-made folks could get their teeth into.

    That handmade coater was only made to show the feasability of manufacture to future clients, not to imitate the Agfa coater on which Agfacolor had been made for the preceeding 10 years.

    A simple perforator is within the capability of of anybody with some drilling and milling machinery.

    Off the shelf solutions have also been suggested by using cine-splicers.

    For myself, if I were coating I would likely be targeting 120 size. Then the issue becomes a stable backing paper which doesn't interact with the film instead of how to punch holes.

    For what is likely not going to be as good as Plus-X or FP4, I suspect a homemade emulsion would benefit greatly from the larger negative size.

    Stable, chemically inert backing paper isn't so easy, however. About the cheapest I ever saw was the stuff on the Shanghai GP3 Chinese film. It seemed almost like children's construction paper. Then you have to print numbers which are chemically inert.

    None of this is impossible, but it sure isn't trivial.

    I think that if I was going to make my own emulsion, I would be more interested in coating glass plates than a flexible film.
