Lathe
Speeds
Before
you mount stock on the lathe be sure the speed is set at “Slow.”
After the stock is mounted, turn on the machine, set the speed
dial to the proper speed and let the lathe come up to speed.
The operating
speeds for lathe turning are determined by the size of the
stock you're turning and the operation you're performing-whether
you're rounding the stock, shaping it, or finish sanding.
Generally, you can use slightly faster speeds as you progress
from rounding to shaping to sanding. You can also use slightly
faster speeds with smaller stock. The larger the workpiece,
the slower the speed should be for each operation.
To help
determine the right speed for the job, use Table 12-1.
