5x7 diy beginner questions..
hello lf community.
this is my first post on this forum. i haven't had the time to properly introduce myself yet, therefore just a few words to explain what i am doing. coming from medium format (rz67) i am about to take my first steps in large format.
i have got access to a metal workshop for another month or so, and the skills to work it, mostly aluminium in this case.
for the moment i bought the necessary parts to start building my first lf-camera. i would like to construct a camera that will be convertible into 8x10 later on, but for now i am thinking about 5x7. havent decided if it will be monorail, most likely, as i havent received the bellows yet. its a 23x23cm (inside) straight bellows of about 70cm..
i bought two fidelity deluxe holders. my main concern is the back part, and my question shows that i have no experience in the field yet.
where does the groundglass go, when the film holder is inserted?
i imagine that the gg is held in place (pressed tight against the back) by bent strips of metal, and that the film holder would be pushed in between?
does somebody here have construction plans? hints? what choices are there to be made?
any help is appreciated.
with very kind regards and open ears,
chris

Here are one person's ideas on building a LF camera: https://jongrepstad.com/building-a-large-format-camera/. The most critical dimension is the distance between the ground glass and the back of the camera that it mates against. This must equal the corresponding distance in the film holder.

thank you. i just found this page yesterday. great, as there are photographs of metal cameras too.
about the back construction, especially the groundglass holder.. guess i will have to measure this as precisely as i can and do some test exposures using a ruler to fine tune.

Hi,

Pali K did a great job with this one I think.
A little bigger than 5x7 but that makes the pictures easier to understand.:)
Good luck...

Monorail - not a good idea! Making stable/adjustable mounts will take a lot more work than the camera!
The standard modern solution of using different formats is to have identical sized loose backs, each with its own GG/and mount for film holders. The mahogany camera era used insert adapter pieces.
The square bellows suggests you are planning a tailboard camera?

Re: 5x7 diy beginner questions..
I'd start by buying a standard 5x7 camera and us it for 6 months before building your own. There are lots of Eastman Kodak 2D camera available as a good place to start.
