Frequently asked questions
What is a steady rest and when is it indispensable?
A steady rest is a support that is clamped onto the lathe bed and supports long or heavy workpieces during machining, preventing flexing and vibrations. It is indispensable when the length/diameter ratio of the workpiece exceeds 4:1 (for a fixed steady rest) or 10:1 (for a traveling steady rest that moves with the tool). Without a steady rest, long workpieces will flex under cutting force, producing taper, vibrations, and non-cylindrical surfaces.
What is the difference between a fixed steady rest and a traveling (revolving) steady rest?
A fixed steady rest is clamped onto the bed in a fixed position and supports the workpiece at a specific point. A traveling steady rest (or follower rest) is clamped onto the longitudinal carriage and moves with the tool – it always supports the workpiece at the same point relative to the tool, eliminating flexing during feed. A traveling steady rest is necessary for turning very long workpieces where a fixed steady rest is not sufficient.
Is this steady rest compatible with my Bernardo lathe?
Each Bernardo steady rest is designed for the models indicated in the title. The workpiece diameter range (e.g., 50–590 mm) indicates the workpieces that can be supported. Verify that your lathe model matches the one indicated. Customer support in Italian is available.
How do you properly adjust a steady rest?
The steady rest must be centered with respect to the lathe axis: mount the workpiece between centers, place the steady rest jaws on the rectified diameter or on an already turned area (not on the rough material) and adjust the jaws until light contact is made. Lubricate the jaws with cutting oil or grease to reduce wear. Do not overtighten the jaws – they should support the workpiece without clamping it.
