How to Use

INSTRUCTIONS FOR MOUNTING B672 3-JAW CHUCK ON TAPER SHAFT

If you typically clamp parts externally by inserting the part into the middle of the jaws and securing, it is recommended that you mount the chuck on the right side of the polishing lathe. If you usually clamp parts internally by placing the part on the face of the chuck and spreading the jaws until they come in contact with the internal periphery, it is best to mount the chuck on the left side of the lathe.

The chuck is designed for mounting on Ray Foster Variable Speed Polishing Lathe, item PR90, as you can control the speed to no more than the recommended 1,500 maximum RPM. If you mount on a 2-speed polishing lathe operate on low speed ONLY.

To mount the chuck, wipe the taper shaft clean. Slide the chuck onto the shaft as far as possible and seat with a soft faced mallet. A couple of firm taps should do it. Test run the lathe not to exceed 1,500 RPM maximum. Stop the lathe and make sure the chuck is secure before using.

Maximum RPM 1,500.
