How to use a parting tool. Then use the BP tool to round the sides of the center ring to form a bead. On a practice spindle use a parting tool to cut two grooves near its center about 38 apart and 516 deep. If this is necessary part the workpiece off with an extra bit of material.

I show how to make a 18 parting tool for woodturning from a HSS tool blank purchased from Amazon.

If using an indexable part-off tool check that the cutting insert is in good condition. Video on how to properly sharpen and use HSS parting blades. This video discusses the basic setup of a parting tool for the best results.
