As requested by Jeff ...
1. Flute up
2. Tool tip well down, lined up with the workpiece 'equator'
3. Feed in slowly with slight side to side swivel motion; the imaginary pivot point ideally should be the tool tip, not the tool rest, so there's a wee bit of sliding on the rest.
Best results with a fresh ground edge (no surprise there).
The swivelling seems to give a cleaner cut, and with the larger beading tools means not all the edge is in contact at the one time and that reduces the chance of a catch.
The tool produces an inset bead with half a V cut either side; leave it that way or turn the shoulders away for a free-standing bead.
You sharpen the 3 bevel faces and they must meet at the edges of the flute.
Clear as mud?
