    Congratulations Gary...I'm jealous, but 8x10 is just out of the question right now. But what a nice looking camera. Look forward to seeing some contact prints from it soon..

    Congrats! Looks brand spanking new. You're gonna have to watch those sky-snakes now.

    CongratS!! I have it's big brother. Gundlach 8X20, and it shares many parts with this one. Imminently useable! You will get a lot of satisfaction from this old camera. My 820 Gundlach rates 2nd in use only to the 810 'dorff. Now you have to watch for the "wells fargo wagon" every day. Don't be afraid to put a "packard" shutter inside and experiment with some of the classic lenses!
    SWEET

    Gary,

    I use an 8x10 Korona. It's the only 8x10 camera I've used, so can't compare it to another. I'm sure other models are more sturdy, but overall I'm very happy with it & quite enjoy using it. Have fun with it!

    OOOOhhhh! Very nice. Now will you be selling that little 4x5 beauty you had at the coffee shop last weekend? if so, DIBS!

    Nah, won't be selling that one soon, I will be selling the Cadet 4x5 and a Bronica. I'm wondering if a lensboard adaptor is available to hang wista type boards on the camera? I'm also thinking of engineering an external battery pack for the 300 Symmars shutter that uses AAA or AA cells instead of that ridiculously expensive battery it's designed to use. I'll probably get a Satin Snow glass for it before too long too.

    Now can someone tell me what the shortest and longest lenses you can use with this thing is? There wasn't too much in the way of tech specs to look at on Ebay.

    Gary,

    I use a 121 SA on mine, but have not tried anything shorter. Using the 121 at infinity, I have about an inch to spare before the standards meet. My bellows will go about 34" I think.

    I just got the camera today. It's a very pretty camera! I mounted the Symmar on the lensboard, routed it out bigger and screwed the Cambo Copal 3 sized board on it. More secure that way and looks good. Next project is filmholders and film.
    Tonight its raining hard and flooding more than I've seen it yet. I had to rescue my wifes car from the small foot deep lake that had formed down the hill. It's in the garage now on the charger, I'm hoping it starts in the morning.

    Shutter project-Help!

    Now I'm looking at that lens. It uses a 4.5v 650 mAh battery to power the shutter. I have some small AA battery holders that will mount on the back of the board out of sight I could wire into it as a replacement and also mount a toggle switch to kill the power and save the battery life. I need to know what value of load resistor I should put inline to keep the current from the AA's down so the shutter coils don't get burnt. The AA's run about 2000-3000mAh each. I don't know what formula needs to be applied to find the right values. Do I need to measure the current the shutter draws during operation to work this out? Do we have a kindly electrical engineer out there who can help?

    I think your current question deserves a new thread. Did you get your wife's car started?

    Yep, after cranking for at least five minutes. It was flooded bad. It's still not happy, all the dash warnings are lit and the brakes are making funny noises. Shes looking at new cars on the net right now.

    This is a bit late so you probably already have an answer, but FWIW: the mAh rating describes the capacity of the battery - nothing to do with the actual current it supplies: that is dependent on the load. In this case, the 4.5V battery's 600mAh rating says it will supply 600mA for one hour, or 60mA for 10 hours, or 6mA for 100 hours etc. If the voltage is correct for the coils, then you do not need to add any resistance.

    3 x AA batteries will supply a nominal 4.5V so that seems fine (rechargeable cells have a lower voltage - typically 1.2V each - but may still work depending on the internal circuitry). I assume that you are simply going to solder leads from the external battery to the existing battery terminals on the shutter? If so, that's all you need to do: you are simply supplying the voltage it is expecting - just make 100% sure you have the polarity correct.

    Cheers, Bob.

    Thats pretty much the case with your average equipment but when you are dealing with the fine coils in an electronic shutter you have to take the batterys internal resistance into consideration. If the coil was designed for a certain battery supplying x milliamps of current it might not have enough resistance in the coil to handle a battery that delivers 4x the current and may burn out. I found a resistor of several hundred ohms and tried it out and seems to work fine with it as a ballast resistor. Thanks!
