while the action of the pole lathe and the skills required are similar to those employed on a modern power lathe, the timber used on a pole lathe is usually freshly felled and unseasoned, "i.e.", green. dry wood can be turned but the work will be slow and rough on the cutting edge of the tools. the angle that the tools are ground is closer to that of a carpenter's chisel than that of a power lathe tool. using power lathe tools on a pole lathe is safe, but hard work. using a pole lathe chisel on a power lathe risks serious injury, since the forces are such that the blade is likely to break. the cutting edge on pole lathe tools needs to be quite sharp, being honed and stropped beyond the grinding, tools for power turning should not be improved beyond the ground edge derived by not finer than 120 grit. the higher speed and friction will degrade the cutting edge very quickly. in this aspect, pole lathe tools do not perform satisfactorily for very long on power lathes and power lathe tools give a poor finish on a pole lathe that will need to be improved by scraping or even sanding after the work piece has dried adequately.
