Loosen jam nuts and set screws so finger
roller positions can be adjusted.
6.
Use finger adjustment knobs to position bot-
tom two finger rollers against workpiece.
7.
Close steady rest, then use finger adjustment
knobs to adjust all three finger rollers so that
they just touch the workpiece without causing
deflection.
Note: The finger rollers should properly sup-
port the workpiece along the spindle center-
line while still allowing it to freely rotate.
8. Lock fingers with set screws and jam nuts,
then tighten clamp knob.
Note: To reduce the effects of friction, lubricate
the fingers with way oil during operation.
