My son wants a carving done in graphite to use as a mold for melted silver. Any advice for working with graphite and the tools that might be needed?
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).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.
