I just want to post this link:http://www.raymentkirbycameras.co.uk/index.htm
Click on 'Workshop' for six detailed and well illustrated and documented sections on building a 5x4 in. view camera.
I have just discovered it and I found the information to be very useful. I wish I had found it before I built my camera rather than after. - I feel a new one being planned right now!
I'm sure many of you are already aware of this but I thought I would mention it for those who may not have seen it.
