    Very nice! Is that an all aluminum rail or wood rail with aluminun "skin"? Is the crank some type of gearing mechanism? The piece that goes on a downard angle from behind the camera going towards the tripod, what is that? Is that for folding?

    Looks great to me, however I do wonder about the front struts and short wide angle lenses.

    Thanks for posting, some very interesting inovations.

    Nice work! I like the focus crank. I suppose that it can move quickly. I used a similar feature on the 4x5 I built. Mine uses a thumb knob rather than a crank and is used for only fine tuning after the sliding rear standard is locked in place at the approximate focus.

    - It's an aluminium rail
    - the cranks going down if for stability of the camera, to minimize vibrations.
    - no folding involved.

    Those who are concerned about wide angle lenses. I don't do wide angle. The lenses are too expensive :wink:
    If I ever happen to buy one, I'll build a new camera specially for it.

    Interesting design. Looks very servicable and fairly stable. Are the slider hardware a standard (bubble pack) item from the hardware store? They look like the sliders used in the lids of cedar chests and the like....I'm asking because I've looked at that prefab hardware several times and wondered about its application to exactly this purpose.

    Once you have had some time with it, please spin us a yarn about it's relative merits and where the design could be improved.

    Brad: right on! I had been looking for those brass parts for weeks before I found them in a home depot style store. The supports are fairly stable.
    I did some test shots tonight, with exposures up to 10 seconds. No vibrations and clear sharp negatives :smile:
