The speed of any lathe is measured by the amount of revolutions the spindle makes in one minute (RPM). The speed needs to be changed from time to time depending on the type of work being carried out. The best speed for turning a particular piece depends on many different factors such as the piece's diameter, the type of wood and whether the piece is balanced. Therefore it is difficult to have a fixed set of speeds that can be remember as every piece has different characteristics. However there is a general guideline that can be used when deciding the appropriate lathe speed. When the diameter of the piece in inches is multiplied by the RPM of the lathe, a number between 6000 and 9000 should be achieved.

Summary of general Considerations:
- Avoid using high RPM unless necessary
- Heavy roughing Cuts - Lower RPM required
- Finishing Cuts - Higher RPM required
- Sanding a piece - Lower RPM required
- Always check RPM before starting the lathe
