Final Alignment

Final alignment of the lathe axis and the copier axis must be precise to ensure that they are both parallel. Before executing the following steps, mount a turning square between the centers of your lathe.

The turning square should be as long as the max- imum center-to-center distance of your lathe to ensure the greatest degree of accuracy. It is crit- ical that the turning blank is perfectly centered and as near-perfectly straight as possible.

1.Move the carriage to one end of the Copy Attachment and crank the cross-feed hand- wheel until the cutting tool nearly touches the side of the blank. See Figure 6.

Figure 6. Aligning lathe to copy attachment.

2.Without changing the position of the turning blank, slowly turn the longitudinal feed handwheel to move the carriage toward the opposite end of the lathe. Use a feeler gauge or another precision spacer when starting out to ensure consistent distance between the cutter and the turning square. See Figure 7.

3.If the cutter does not maintain a consistent distance from the turning square at both ends of the cutter’s longitudinal movement, or along it’s length, you may have to loosen the bed from its mounting brackets and very

very carefully adjust the bed until the cutter is equal distant from the turning square at both ends of its longitudinal movement.

4.Continue to test the cutter against the turn- ing square until it is evenly spaced in rela- tion to the turning square along its entire length.

5.Once adjustments are complete, ensure that all mounting bolts are securely tight- ened.

Avoid wearing loose-fitting clothing, jewel- ry, or other personal items that could be caught in moving parts of the machinery while adjusting or operating this machine. Serious personal injury could result if this warning is ignored.

NOTICE

If the carriage is difficult or impossible to move along the bed, see Gib Adjustment in next section.
