Jon Grepstad: Building a Large Format Camera. ISBN 82-993938-1-7
Plans and Instructions for Building a 4 x 5 Monorail Camera.
Second, revised edition. Oslo, Norway 2000.
My book Building a Large Format Camera is an 85 page manual with instructions and plans for building a 4 x 5 in. monorail camera with friction focusing. The book has 30 step-by-step drawings, 23 sketches and 11 photographs, a wealth of references to relevant literature and numerous useful addresses in the US and Europe. Most drawings are to scale.
The first edition of my book appeared in 1996. For the second edition,
which was published at the beginning of January 2000, 20 new illustrations
have been inserted in the text, 10 photos of the camera have been added,
more sources of information on bellows-making have been included, and the
literature and references have been updated. I have also added as an
option a more sophisticated ground glass frame design and also a few
paragraphs on scaling the plans up for an 8 x 10 camera.
Materials: Hardwood, brass, rail. Skills needed: Average woodworking
skills. The camera has been designed so that it does not require very
advanced skills or tools to build. Tools: Electric drill, various
handsaws, miter box, c-clamps, files, carpenter’s square, other ordinary
tools. To be bought: Standard bellows (may also be handmade), ground glass
(you may also make your own ground glass), lens.

My latest design of a ground glass frame.
Two designs of a ground glass frame. The version to the right was my original design (used in the first edition of my manual). The version to the left is a more sophisticated design (included in the second edition of my manual).
My latest design of the camera back and a ground glass frame (film holder inserted).
My first design of the camera back and ground glass frame.
The optical bench consists of an aluminum rail,
two sliders and a tripod block. The optical bench in my book
is based on friction focusing.
