Works well in my wood lathe
The expanding Mandrels fit the rings nicely and allow me to work on my wood lathe with the proper drill chuck installed…a nice convenient feature.

Solid Mandrel
Had to get this due to a larger ring than what I had been making. Solid! Easy to use and get your blank on straight- even when it is covered in electrical tape.
