I'm not sure how helpful this will be, but when I worked in a machine shop
and made similar, I used an endmill with the material mounted vertical in a
fixture. If it was thin, I would sandwich it between two sacrificial

drill press or possibly a router. Any excuse for a new tool! Here are
some ideas
