He's going to provide the graphite and it will be used to make silver pendants. I am wondering if you have any advice on what bits, speed and feed rates etc to use on a cnc machine. I also will need to add the graphite to my materials list. Would it be more closely related to a metal or a stone?
As I'm sure you have deduced by now, I am such a newbie.
Thank you for any suggestions in advance.
You are going to have to get answers to all of that from someone else, I don't do CNC machines. Were it me, I would just make my molds out of clay. Instead of silver, I might well use metal clay (at least I think that is what it is called, a combination of clay and whatever metal you will be using).
Been a really long time since I was interested in any of this type of stuff, and that was in large part just lost wax casting. However, thinking on it, may be worth my time and effort to make a small forge, along with a few custom molds, and make some branding irons. I'll have to see what I have, and what I need to get.
