To pursue on micro turning, last time I showed a tool holder made for turning tiny coves, here is now a tool for making micro beads
It is made from a carbide scraper blade, it is very tough an holds its sharpening very well, and it can be used even in brass.
I have 1 mm bead shape at one end,
and 2mm at the other end.
It is used with this tool holder
Here you can see the shape and how I sharpen it with a diamond conical bit on the Dremel.
