Chuck and back plate join here.
Socket head cap screw
Figure 7. Remove screw from the back of chuck.
If the chuck is still tight on the spindle:
Tap the edge of the chuck with a rubber or wood- en mallet while supporting the bottom of the chuck with your free hand. If the chuck does not immediately come off, rotate the spindle approxi- mately 60˚ and tap again.
To install a chuck:
1.Place a piece of plywood across the lathe bed and position it just under the spindle.
2.Place a socket head screw into one of the holes in the back plate. Lift the chuck up to the spindle and align the threaded hole in the back of the chuck with the screw.
3.While supporting the weight of the chuck, turn the screw 3 turns. Do not tighten at this time.
4.Rotate the spindle and repeat step 3 on the last two screws.
5.Return to the first screw and tighten it a little more. Tighten the other screws as well but only enough that the gap between the chuck and the back plate remains even.
6.Finally, tighten all three screws until the gap between the chuck and the back plate is closed.
