    Mounting/Removing Chuck or Faceplate ACCESSORIES Page 50 Tools Needed Mounting a Chuck or Faceplate Figure 29 Figure 29. Debris or grit on the mating surfaces will not allow the chuck or faceplate to evenly seat onto the spindle back plate. This con- dition could allow the chuck or faceplate to vibrate loose during use and cause serious personal injury.

Thrown objects from a lathe can cause serious injury or death to the operator and to bystanders many feet away. Removing Jaws from 3-Jaw Chuck Note: Each jaw will move until it becomes loose from the scroll gear threads, then it can be removed by hand.

  • Page 37: Offsetting Tailstock

    Using a Dead Center in the Tailstock Note: For stability and accuracy, the tailstock quill with the dead center mounted should protrude between ⁄ " and 1 Note: The force against the mounted workpiece will fully seat the center's taper. However, do not overly force the center into the workpiece—this will make removing the center very difficult.

  • Page 38: Aligning Tailstock

    Aligning Tailstock To align the tailstock: Page 16 Note: If the tailstock is slightly out of align- ment by a few thousands of an inch, the center drill will find the center point during the drilling process. If the tailstock appears gross- ly out of alignment, move the tailstock until it appears to be centered (refer to the previous subsection for detailed instructions).

    Follow Rest Figure 45. Tools Needed To use the follow rest: Tip: To further avoid deflection of the workpiece during setup, use the method Figure 45 shown in Figure 46. The test indicator is set directly opposite the brass fingers on the workpiece, then the brass finger is moved into the workpiece until the dial on the indi- cator begins to move.

  • Page 44 Setting Lathe Speed Calculating Correct Spindle Speed Figure 54 Note: Cutting speeds are expressed in sur- face feet cut per minute (SFM). Recommended Cutting Speeds Rough Cuts Note: These values are based on HSS cutting tools. For carbide cutting tools, double the aver- age speed.
  • Page 45 Note: Your lathe/mill ships with three V-belts of varying length for the lathe spindle speed configuration: 1) 26", 2) 28", and 3) 29". Use your best judgement when deciding which length of V-belt to use for each pulley con- nection.
