    Gralab timer bogging down

    Hi Everyone,

    I've got a couple of Gralab timers in my darkroom, the typical big black dial model which I believe is a 300. They were given to me and probably date back to the 1970s or early 80's.

    One of them has developed a problem where it will work a few times and then start bogging down. For example, I might be able to process one roll of film without any problems and then at the end of the next 8-minute film development it will hit the last 20 seconds or so and slow to a crawl. After that happens the timer runs super slow and I can't use it anymore. Next time I come into the darkroom it will work fine until it bogs down again. When it is working it is still perfectly accurate.

    Has anyone had this problem? Any suggestions for things to look for if I open it up?

    Regards,
    Anthony

    I had one like that. I recommend throwing it away.

    Sadly, those Gralab timers are a dime a dozen these days. You're probably better of just getting another one.

    throw it out before it happens in the middle of a processing run like mine (two of them) did.

    Ya, I just bought one for $15 CDN. Didn't really need it, but for $15 it's a good back up.
    Way less that I paid for my original one - way back when!

    Thanks for the replies, it sounds like I'll probably stick to my wristwatch for now and see about a replacement timer.

    I like those Gralabs for the simplicity of the single big dial. I'm not interested in a digital timer as it implies a level of precision that I certainly do not have in my work.

    Perhaps those posting can send you a new one. From my experience, a late model 300 that is going to be in better condition than what you currently have might cost over $50.
    To fix the one you have I'd measure the amperage draw when working and when 'bogged down' If the amperage goes up then take it apart and look for a source of binding. If the amperage goes down when running slow, look for a poor electrical connection or bad wiring.

    I just bought one for under $30 and saw a brand new one go for for $50 on Ebay.

    I haven't found a digital timer I like, they're all too complicated

    Though I have never taken one apart, they seem to be pretty straightforward. At least take a peek inside.
