Removing Center from Spindle
To remove the sleeve and center from the spindle, insert a piece of round bar stock or similar tool through the outboard end (on the left side of the headstock), then tap the sleeve loose.
Note: Hold onto the sleeve and center as you tap them loose to avoid dropping them and damaging the tip of the center or the bedways.
Mounting Center in Tailstock
Either a dead center or live center can be mounted in the tailstock. Mounting instructions are the same for both. Figure 67 shows an example of a dead center mounted in a tailstock.
Dead Center
Figure 67. Example of using a dead center installed in
the tailstock.
To mount a center in the tailstock:
1.DISCONNECT LATHE FROM POWER!
2.Thoroughly clean and dry the tapered mating surfaces of the tailstock quill bore and the
3.Use the tailstock quill handwheel to feed the quill out from the casting about 1". (Do not feed the quill out of the casting more than 2" or stability and accuracy will be reduced.)
4.Insert the center into the tailstock quill.
5.Seat the center firmly into the quill during workpiece installation by rotating the quill handwheel clockwise to apply pressure, with the center engaged in the center hole in the workpiece.
Note: Only apply enough pressure with the tailstock quill to securely mount the workpiece between centers. Avoid over- tightening the center against the workpiece, or it may become difficult to remove later, and it will result in excessive friction and heat, which may damage the workpiece and the center.
Removing Center from Tailstock
To remove the center from the quill, hold onto it with a rag in one hand, then rotate the tailstock handwheel counterclockwise to draw the quill back into the casting until the center releases.
