The most complex part of a large format camera is the spring back. Not that it is particularly complex, it is just that the rest is rather simpler.
Before I started cutting up wood I wanted to make sure that all the parts fit together properly. To do this I have made a spring back using materials I had readily available.
The grey parts are cut from 9mm nylon, the brown parts are from a 3.2mm composite material and the green parts are 1.6mm FR4 PCB fib
reglass.
The fibreglass parts are the big surprise here as they are the springs. Usually, the springs would be made from spring steel and once I have perfected the design, I will have some made. The fibreglass springs do work very well though.
All of these parts were cut using a CNC drill/router which I have at work. This saves a lot of manual labour and allows me to try out various ideas.
