    To everyone interested;

    I spent a few spare hours while washing and drying some of my AZO type emulsion prints to read up posts about my work on other sites. I nearly laughed my head off, so here are my comments. At least with some of the posts. Others were very inaccurate or rather nasty. Some were deleted and I had to read the caches.

    1. I'm not 80 or older, I'm considerably younger. I retired early from EK.

    2. I don't think film will expire before I die. I think I will go first, but being one of the few willing to share the technology, I'm trying to get going on it before I cannot do the job. (I would prefer an apprentice to do all the hard work, any vounteers?)

    3. I don't have the patent on rapid fix. I worked on fixes and blixes for color and have a patent (with 2 other co-workers) on color film blixes. I designed the color paper blix, but it is not patentable due to prior art. (if I had $0.01 for every liter of paper blix sold, I would be a very very wealthy person.. LoL)

    4. The coating blades work. They are used (or were) at EK for years and years to coat small coatings in the research labs. Denise Ross has posted her URL here as have I, and on that site you will see some of her work. Development times were long due to the fact that there were about 3 prototypes, and the cost is high due to over a 50% reject rate. This is a technical problem due to forged stainless steel which is cut either by water jet or milling machine. The cost is based on this as well but is at least 50% lower than the nearest product I could find. That web site is out of business. The bottom line is that the blades are not BS!

    5. My workshops (2 of them and 2 more scheduled this fall) have achieved a good ISO 40 ortho film. In the first, the film was a bit foggy and in the second the film was low in contrast, but they both agree that the speed is a solid 40 whatever the faults. I'm working on those problems.

    6. To my critics, you all have good points. My only answer is that what I'm doing works. Let me see your work. I'm open to suggestions and have sent notes to those concerned offering to work with them. To date, I have had no response from them! I am sad about this. I had hoped for more from this.

    7. In addition to the film and paper emulsion making and coating, I would be willing to offer a B&W system design series and a color system design series if anyone is interested (see the starting posts on PN which died due to lack of interest). This would be a "How things work" series.

    I'm willing to add any other items here that you suggest either in support or in criticism. I am fully open to comments.

    To the moderators, you may move or delete this if you wish, as if I had an option. LoL.

    Basically, I think what you achieve in the real world (workshops, coating blades, etc) speaks for itself. And even if you just spread your own knowledge without doing anything else, you still would be doing something constructive.

    You do what you do - do it for your own pleasure and wellbeing - and let the others talk.

    I don't see anything potentially objectionable. Thanks for the update.

    Although I am not presently coating my own emulsions for paper and / or film, I always enjoy reading your posts which are from a usefully different perspective compared to what we are usually exposed to from books and magazines etc.

    Thanks,

    Tom Kershaw

    Thanks for all the comments. I really wasn't looking for a pat on the back, but thanks.

    What I was doing was reading the posts people made about me 'behind my back' so to speak. Some good, some bad, all valuable and some of it amusing. In some spare time, (HAH!) I did a google search on my name, and came up with several pages of comments by others about me and my work. It was interesting reading and quite educational.

    I've got some interesting things under development. You will see them as soon as possible.

    Ahhh, nothing quite like an afternoon of ego-googleing:wink: . I guess we all can relate to it :D .

    Anyway, back to the thread topic - well, I for one am always looking forward for posts from you. Thers's always something to learn, and hey, I might even jump for a set of coating blades next year (when my darkroom has hopefully progessed past the sketch-on-a-paper-napkin stage).
    But what I would really LOVE to see is an indepth book or ebook about your methods in emulsion making and coating. Sure, it couldn't replace the real-life hands-on experience one would gain from attending your workshops, but it would be the next best thing for everyone who can't attend the workshops for one or another reason (myself included).

    I hear you, and everyone else.

    The googleing was not for an egoboo, it was to learn. I'm too old for an egoboo. LoL.

    Boos are always useful too! That is what I went out there to learn about.

    You're the reason my mum is worried I'm gonna blow up something new while looking into emulsion making, have to be proud of that. I guess people are used to wise figures being old and grumpy and trailing off about that one onion they had in nineteen-dickity-two, or are naturally skeptical someone might know what they're talking about. So far so good though, at least no one's calling you a communist yet.

    Ron:

    I have two winter projects this year:
    1. Complete 10 copper photogravure plates.
    2. Master emulsion coating and start producing papers and film.
    The second might be more ambitious than realistic, buts its on the agenda.

    I imagine you will hear from me quite a bit as the winter season proceeds.

    Regards,
