I am having trouble I am hoping someone can tell me what I am doing
I am cutting threads like a nut and bolt for threaded earrings. Each
piece comes out nicely, sharp clean cuts. The problem is when I screw
them together they round. The pieces are not heat treated or
hardened. Is that the problem? I’m mostly doing 14kt and casting both
pieces, but it seems to happen in any metal so I’m sure it’s me. I’m
using the jewelry tap/die tool, a little burr lube, the correct size,
both pieces are 1.9mm. I’ve seen some other pieces that others have
done and they are crisp.
Any suggestions are appreciated.
