Well Rich, I would love to answer your questions, but it would be
nice if you gave us an email address to email you offline at. Aside
from being a custom jeweler, I spend my days as a Design/Project
Engineer for the cosmetics packaging world. I routinely create part
prints to be sent to toolmakers and machine shops for Quotation and
creation in steel, plastic, aluminum and brass. Let me know what
knowledge you need.
