    Some hand scraping were done to ensure good contact between column and the base. Chip tray welded from 2mm thick hot rolled steel. Pretty tough thing...

    Add Z shaped grooves to the saddle for liquid oiling of the ways.

    Looking great John .. really like the new head /spindle setup .. I've decided to go in that direction myself .. thinking about a welded steel head, but still only in planning stages right now so still not sure.
    Keep up the good work!

    Gary

    So the machine has been complete and making parts for 8hrs a day for 2.5 years? That’s pretty impressive

    Very Nice John!
    Did you have the casting made, or is it something you are re-purposing? It ought to be very solid.
    What RPM will you be able to get out of the Servo Spindle Motor?

    The casting was made on the foundry using my drawings. This is not a problem for me.
    Spindle servo rated to 3000 RPM and i am planning to use pulleys 1 to 1.5 to increase the RPM at least to 4500.

    The spindle is made in Russia by my friend. It cost about 500$. There is no necessary to build such spindle today, you can easily purchase it on Aliexpress for the same cost.
