This is an example of eccentric woodturning of an oak bowl. The diameter is about 40 cm and the height is 8 cm. With fresh wood I use a classical metal 4-jaw chuck. First, I turned the exterior, then I made an opening placed eccentrically at the bottom of the bowl, and finally I did the interior. I do not pay special attention to the quality of the surface as wood deforms and it will be turned again once it is dry. I look forward to the result!
