Living up to expectations, the open-source mini lathe V2, viewed by tens of thousands, is now complete. The bearings cost one yuan each, the timing pulley and belt twelve yuan, the linear shafts sixty cents apiece, the brass bushings also sixty cents each, the linear rails with sliders twelve yuan per piece, the T8 lead screws seven yuan each, the T6 lead screws five yuan fifty each, the vertical lead screw mounts two yuan each, and the M3 screws and heat-set inserts cost two yuan in total. Step one: press the nuts into the 3D-printed parts. Next, install the linear rails. Install the T8 lead screw nut. Secure the slider and adjust the parallelism of the linear rails. Install the bushings and the T6 lead screw nut. Install the linear shafts. Mount the Y-axis platform, which moves very smoothly. Install the square tool post and tighten it with screws. Secure the X-axis T8 lead screw. Install the drive motor and fit the spindle bearings. Mount the three-jaw chuck on the spindle. The V2 version features an updated extendable tailstock; let's see how it performs. Many people have concerns about rigidity, so I specifically designed it to be compatible with standard breadboards having a 25mm hole spacing. A concrete base will also be released later, using the same mounting method as the breadboard. The model files are open-sourced on MakeWorld; just search for "Qianbian" to find them. Multiple color schemes are provided for reference. Which color scheme do you like best?
