Hello Friends I have bought this miniature lathe on local fly market. I could not resist to buy this little beauty //I can cover it with man handkerchief//. I did some negligible de rustings and attached new motor with speed controller because original speed regulator is death. During refurbishment I have found that offset of main spindle is 0.03 mm. IS THERE A POSSIBILITY TO IMPROVE THIS OFFSET TO HIGHER PRECISION ? Thank you guys for your advice.
