This mod simplifies single-point threading on mini lathes
Reading Time: 2 minutes“Single-point threading” on a lathe is the process of cutting threads, such as for a bolt, into the material through turning. The spindle/workpiece spin and the carriage moves linearly at a precise amount per turn of the spindle. That linear movement is the thread pitch. But this process usually requires several passes…
