What I have is a stack of three washers (3/8th inner hole) that have been steel-epoxy'd together to form a cylindrical stack. I need to do some shaping of this stack, and they are zinc-plated. What are some cheap options that could get the job done? I need to be able to cut one side flat and shape another into a hook-like pattern. I heard from one person that a hacksaw with the right blade can do that, but other places say that it won't work very well. Given how small the material is that I am working with, I don't want to run it through my bandsaw and risk chopping my fingers off if it gets caught on the blade.
