Figure 11.2 You can do other turning cuts with different cutter bits and cutting tools.
Machining Square Corners
To machine an accurate corner, follow these steps:
1.
Set the compound rest perpendicular to the line of the centers and insert a right or
left-hand corner tool.
2.
Using the longitudinal feed, turn a small diameter to finish up to the shoulder.
3.
With the compound rest, feed the tool the amount needed to finish the work to the
length, taking the last facing cut across the shoulder away from the center.
Finishing and Polishing
After machining, you'll want a smooth, polished surface free of machine marks. You'll
obtain the best results with a toolpost grinder. If you don't have one, use a file.
With a file, take full, biting strokes across the revolving workpiece at a slightly oblique
angle. Do not drag the file back across the work-piece; instead, lift it clear for each return
