Fig. 8.11. Unmachined soft jaws. You can machine any shape you like into these
jaws.
Fig. 8.12. Chuck fitted with external jaws. The backplate is threaded for the lathe but
is the same bore and thread as the dividing head.
The chuck should be zeroed under the spindle using a dial test indicator.
Put a bit of bar or a component into the chuck and clock it true. Set both the
X and Y axes to zero using the digital readout or the hand wheel graduations.
