I have a film holder for 14x17.
I have an APO-Nikkor 610mm f9 lens that will cover this format.
I have plans for an Anthony style plate camera that I purchased from here: http://www.wetplatecameraplans.com/

Now, I am trying to source the spring steel for the film back (I am not planning to use a plate holder). I was thinking that something like this would work: http://www.mscdirect.com/product/details/03342185

It appears to be the correct width and thickness to use for the project, but I am not sure. Another thought is how difficult would it be to bend the loop to hold the pins, that are attached to the wood frame of the back? Is that even possible, without losing the spring?

Any thoughts on whether or not this would work?

Thanks!
