I’m looking for some advice please on how to finish the edges of stamping blanks.
I’ve tried disk cutters and they give a nicer rounded edge to the shape but i’ve just bought a cutting machine and the shapes come out more straight on the edges.
I was looking at mini bench polishing motors but the assistant sold me a barreling tumbler machine with some mild steel shot and told me that after 10 minutes it will smooth and round the edges to be the same as the circle disk.
I tested an oval shape I cut out and tumbled it for over an hour but the edges are still very straight compared to the circle disk I have as the finish aim.
It there a way to round and smooth the edges in bulk to make it look like the circle disk? (I’ve attached photos)
I’m wanting to make large and very tiny shapes (like 5mm tiny) and it will take forever to file and sand the edges by hand on each one.
If anyone can help that would be amazing.
