Want plans for a small jeweler's rolling mill

All,

I had recently moved to northern Idaho. I’m in close proximity to a
friend who owns a wrecker service with access to lots of steel scrap
and heavy machining equipment such as an engine lathe and a TIG
welder. He’s interested in tutoring me in these tools.

Now would be a very good time for me to ask again of everyone, where
I could possibly obtain a plan, even a patent filing, for
constructing my own jeweler’s rolling mill. I’m cash poor and can’t
buy my own, but I have plenty of time and access to equipment.

Thanks in advance,
Andrew Jonathan Fine
