    Default Vacuum frame question

    So I just had a big ass Cincinnati Vacuum frame delivered and I have a question. When you turn on the vacuum and it's fully sucked everything together, do you need to keep running the vacuum pump? Or once it's fully drawn do you turn off the pump? I know there is at least 1 leak in the blanket so when I turn the vacuum off I lose pressure . . . but Im curious if the pump stays on or off on units that function perfectly.

    Yes, when I'm teaching the students always want to turn off the vacuum once it's sucked down. Even after I've told them not to, but they only ever make that mistake once.

    You may be able to patch that leak with a standard bike tube repair kit. We use a stretchy blue vinyl tape.

    I also don't take any chances of the film slipping and atpe my films in place to the glass with some magic (clear) tape.

    shoe goo also works for patching holes in the blanket. or go to a surf store and get a wet suit repair kit.

    I patched some severe rotten spots using sheets of old blanket rubber and contact cement. the difference was night and day as far as suck down, and it was prompted by shittier and shittier detail from not having complete compression. if you are printing detail, and want to expose everything on your film, you have to have complete compression, otherwise the light will leak under and expose/close up your finest dots and lines.

    As for shutting down the pump...I would never do it on mine, cause the rubber is still got lots of leaks, and you need to rotate the whole thing for exposure, but the crazy Mexicans from the factory were showing me on our Eagle tabletop units (non rotating) you can shut the vac off and the rubber will completely stay sucked down for an exposure. They provide a switch to break the vacuum when the exposure is done.
