I am starting work on a 8x10 reducing back for an 11x14 camera. I am using the back on my Commercial View for a rough guide. The parameters of this job require stainless steel for the springs.
I am woefully lacking in materials knowledge concerning stainless steel grades and designations. So I have a few questions for anyone with knowledge about stainless that is used for camera springs.
I assume the springs are made from the same grade of stainless that a fairly stiff spatula or pastry knife is made from. The springs on the commericial view are .040" thick. Is this type of stainless, already tempered for flexibility available as stock or would you need to buy stainless and heat treat and work it first to achieve the qualities required for a spring? (outside my range of ability).
If it is available what is the grade designation? (301, 302, 17-7 etc)
I can buy commercial grade spatulas and flexible knives up to 18" long and cut out springs on a water jet. It would be better to be able buy a piece(and less expensive) 20"x20" to cut pieces from for future projects if available.
Thanks in advance for any and all answers.
