DIY metal minilathe [part9] Is it spinning?

Part 9 of the making of my DIY precision mini lathe for metals with electric axes. In this episode the final assembly of the elements that form the carriage, including the apron. To align the cross-slide with the lower sleds that run on the Z-ways I used a self-made machinist level, here you can watch how I've made it:    • Machinist level with a perfume vial   Unlike in typical manual lathes, here the apron is much simpler as it is directly linked to the lead screw and to the axis driving motor. A double nut, with a particular linkage, is used to adjust the backlash. Finally the spindle is put in rotation with a couple of DC motors salvaged from washing machines and controlled with a simple driver (AKA ESC, details in this video:    • All you want to know for driving powerful ...  ). This work was put on pause for four months because a surge of work in my main job. I found two problems with the spindle's motor. One is a faulty contact somewhere in the control board that makes the motor running irregularly. And the other one is the belt that slips on the shaft of the spindle, because the pulley that was meant to pick the thrust from the belt to transmit it to the shaft is not yet in place. Hopefully that will solve the problem. Previous episode:    • DIY metal lathe cross slide sled - part 8b
