Mounting Center in Tailstock

The included MT#2 dead center or a live center (not included) can be used in tailstock. Mounting instructions are the same for both. Figure below shows an example photo of a dead center mount- ed in a tailstock.

Dead Center

Figure 38. Example of using 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 tailstock quill bore and center, making sure no lint or oil remains on tapers.

3.Use quill handwheel to feed quill out from casting approximately 1”.

Note: The maximum quill travel is 2", but we do not recommend extending quill more than 1" or stability and accuracy will be reduced.

4.Insert center into tailstock quill.

5.Seat center firmly into quill during workpiece installation by rotating quill handwheel clock- wise, to apply pressure with center engaged in center hole in workpiece.

Note: Only apply enough pressure with tailstock quill to securely mount workpiece between centers. Avoid overtightening cen- ter against workpiece, or it may become difficult to remove later, and it will result in excessive friction and heat, which may dam- age workpiece and center.

Model G0765 (Mfd. Since 12/13)

Removing Center from Tailstock

To remove the center from the quill, hold onto it with a gloved hand or shop rag, then rotate the quill handwheel counterclockwise to draw the quill back into the casting until the center releases.

Mounting Workpiece Between

Centers

1.DISCONNECT LATHE FROM POWER!

2.Drill center holes in both ends of the workpiece.

3.Install MT#3 dead center in spindle with lathe dog and chuck or faceplate, then install live center or MT#2 dead center in tailstock.

4.Lubricate MT#2 dead center point and workpiece center holes, then mount workpiece between centers and hold it in place with light pressure from tailstock center.

To avoid premature wear of the dead center or damage to the workpiece, use low spindle speeds and keep the tip of the dead center mounted in the tailstock well lubricated.

5.Seat center firmly into quill by rotating quill handwheel clockwise to apply pressure against workpiece (see example below).

Figure 39. Example photo of a workpiece

mounted between two centers.

Note: Only apply enough pressure to securely mount the workpiece between centers. Avoid over-tightening the center against the workpiece, or it may become difficult to remove later. Also, over-tightening will result in excessive friction and heat, which may damage the workpiece or center.
