- Fully adjustable head assembly that can be set for the size and curvature of your project. Unlike most other head assemblies for bowl grinding machines, our bowl grinder uses steel bearings for ultra-smooth spindle rotation on your lathe. - When finishing the inside of a turned bowl, protecting against abrasion and safeguarding your hands can be challenging. Our bowl grinder solves this with a double-bearing, smoothly rotating head that turns with the bowl as the lathe spins. The 352 mm length also helps keep your hands away from the working area. - This design also reduces the risk of marks, since the grinder rotates without snagging or binding like many other brands. Results depend on applying the correct amount of pressure and maintaining a steady technique. If you use a two-stage sanding setup, too much pressure can lead to less desirable results. - Use scenarios - Finishing the interior of a turned wooden bowl on a lathe. - Smoothing curved interior surfaces in bowls and hollow forms. - Gentle, controlled removal of tool marks inside a bowl with reduced risk of hand fatigue or injury.
