The present invention surrounds a gouge for use in woodturning, particularly in the fabrication of wood bowls, wherein the gouge is configured to provide longer reach with decreased deflection. The decreased deflection allows safer and more efficient woodturning process, resulting in better quality woodturning products. The gouge includes an inner cutting profile which is offset upward from the center of the outer profile, thus providing more structural rigidity when extending the tool from a tool rest and into the concavity of a bowl being turned.

Lathe control systems and methods are described including stopping a motor prior to reversing direction as well as methods and systems that implement voltage and/or current protection thresholds.

A central axis adjustment structure of a tailstock of a woodworking lathe is disclosed. The tailstock has a circular hole therein, a front opening and a rear opening at front and rear ends of the tailstock. An end surface of the front opening has at least one screw hole. A guide rod is disposed in the circular hole, and has a rear end extending out of the rear opening. A collar is fitted onto an axial connecting shaft that is inserted in the circular hole. The guide rod is insertedly connected to a rear end of the axial connecting shaft. The collar has at least one perforation corresponding to the screw hole. At least one bolt is inserted through the perforation and screwed to the screw hole so that the collar is locked to the front end of the tailstock. A first annular gap is defined between the guide rod and the rear opening of the tailstock. A second annular gap is defined between the axial connecting shaft and the front opening of the tailstock. A third annular gap is defined between the bolt and the perforation of the collar.

A speed change auxiliary device of a lathe is provided. A side chamber of the lathe is provided with a shaft seat and a bottom shaft seat at the top and bottom thereof. An auxiliary device is provided between the shaft seat and the bottom shaft seat. The auxiliary device includes a shaft. A spring, an eccentric block, an engaging member, a positioning nut, a rotary sleeve and a fixing block are fitted on the shaft. The rotary sleeve includes a handle. Two sides of an inner circumferential surface of the rotary sleeve have protrusions. The protrusions each have an upright surface and an upper guide bevel at two sides thereof. The fixing block is disposed on the bottom shaft seat. Two sides of a circumferential surface of the fixing block have recesses. The recesses each have a stop surface and a lower guide bevel at two sides thereof.
