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.
