making a mini lathe had been an idea in my mind for a long time until i saw someone's. and then i made this by aluminium alloy sections and aluminium plate. but i didn't take too many pictures for all the steps because sometimes i forgot.
this lathe can be extended when you add some module. it can be a table saw, a grinder... and it will help you do many things only if you have ideas.
list of materials:
AL alloy sections length 3060: 650mm*2; 1560: 200mm*2; 3030: 650mm*2 40mm*2 100mm*1
AL plate: 120mm*100mm*10mm*2, 120mm*20mm*10mm*4
motor 220V/250w RPM forget
4 jaw chuck: Φ65mm screw thread M14*1
drill chuck: B16 joint
bearing with base Φ20mm *4
spindle: Φ20mm, one has screw thread M14*1 on the both ends, another has a B16 joint for drill chuck
motor belt: Φ6mm Polyurethane
sliding table 50mm*150mm*30mm
Step 1: the material
fix the rails, after rails are for the electric motor
fixed them on the epoxy plate.
