    are you planning on manually moving the mirror UP to block the ground glass and be out of the way of your film / plates ?
    or a springed arm ?
    if springed, you might look into using the sunshade that is on pacemakers, it already has a spring you might be able to slide a mirror
    on the dark slide holder clip and it might be close to the right dimension and easy to slide in ...
    you could probably remove the graflock back altogether, put a second one on the top of the box , the sunshade inside with a mirror
    .. come to think about it there might be a slr type press camera that has that design, unless I am thinking of something else. ...

    i'll be cutting a roughly 2"x5" section out of the top then reattaching it with a hinge so it flips up out of the way and the gg can come up right in front of the fp shutter to minimize the amount of bellows space taken up by the mirror box. i'll be adding a small lever to the mirror box near the fp shutter release so i can raise the mirror with one finger and release the shutter with another finger.

    Reflex 4x5 camera IS limited to lens focal lengths long enough to clear the mirror to film holder. This means not using the reflex mirror set up for any wide angle lens (likely 100mm and less). This is essentially carrying over the fixed box with fixed lens mind-set-ideology into sheet film which is not the same in many ways.

    TLR is another option to the SLR aproach:

    i'm familiar with all those cameras. i have considered all of them as options as well as the option of building a tlr, which i already have two perfectly good designs for. as previously discussed in this thread, for my specific needs, building an slr out of a speed graphic is the best option available. that is the topic of this thread. i'm not looking for alternatives. i know the focal length limitations of slrs. those have also been discussed in this thread previously, and again, that's why i'm making the mirror box removeable. it's typically more like 180mm than 100mm btw, but that's fine for my specific needs. i don't care in the slightest about mind sets or ideologies or fixed boxes with fixed lenses (this has neither). it's just a camera, a tool for taking photos.

    sounds like an interesting plan! I have several LF / SLR type cameras and sometimes the body that holds the mirror even when seated all the way up to the top of the box, well it clips the image, so keep in mind it might be necessary to maybe add a little height / width to the box.
    If I can ask, do you do street work? 'scape imagery / architectural or portrait sort of photographs?... and do you have a favorite f-stop ? I ask because there may be other ways in addition to what you are doing, to quickly focus and compose.

    btw doll house mirrors are thin and can be trimmed with scissors and glued to anything..

    good luck

    I haven't read any of this thread except for the title, so I may be way off-base here but . . .

    Why not get one of the Graflex Reflex cameras? Why not get an RB 67?

    There are only three types of mounting flanges; too big, too small and wrong thread!

    Try reading just one post (other than your own): post #4. Your suggestion makes too much sense if the real goal is to photograph with a LF SLR, I fear. LOL

    the "real goal" is to have the functionality of a LF SLR available for subjects that a speed graphic isn't suitable for. i've been over this again and again. BUYING AN SLR IS NOT A VIABLE OPTION FOR ME, AT ALL, PERIOD. if you can't be respectful, get lost.

    If you can’t be polite and stop writing like a jerk I will “get lost”. I’m okay with your tinkering effort… it’s just a long way to go for that goal. If you can’t afford or just don’t want to buy another camera that fits that need, I can respect that. I would like a Graflex SLR and won’t pay the price too.
