Ok, 'solutions guys'...
I have some 0.010" phosphor bronze (spring temper) in rolls 6" wide x
80" long.I need to cleanly slit some 3/8" strips x 80" from this without any edge distortion.
We tried taking one a sheet metal house that had a long scissor-type shear, and it cut it, but also curled the edge too much for our application. It has to wind flat in a coil when finished.
I've tried sheet metal hand shears without much joy, a nibbler just chews it, and sawing it on anything we've got is impossible.
We must not heat it. Also cost is an issue, or I'd have it done at a waterjet and laser house down the road, but they want a couple-hundred just to set up a job. For only five strips, that's not in budget.
A virgin roll has perfect edges, and rolls tightly. The mill that makes the rolls from larger sheet stock cannot go narrower than 1".
Any ideas?
Thanks, Lloyd
