PM-1440GS HEADSTOCK ALIGNMENT
Figure A1 is an exaggerated view of what happens if
the spindle is not precisely aligned with the lathe bed.
This is correctable by
slightly
loosening the attachment
screws, Figures A2 and A3, then adjusting the screws
set into a tab rail below the headstock, Figure A4.
Figure A3
Misaligned headstock
In this illustration the workpiece diameter increases as the cut-
ting tool moves toward the chuck. Correct this by screwing in
(A) a fraction of a turn to rotate the headstock counter clock-
wise, moving the workpiece away from the tool. Screw in (B) if
the taper is in the other direction, thinner toward the chuck.
