    Re: Small Affordable Desk Top CNC Lathe

    Re: Hacking a CNC machine, but which one ?

    Re: Accepted Bearing stack for Ballscrew

    Excellent, thank you all for your comments. I'm glad to see that the double row bearings will not need to be shimmed in order to function correctly. This should make installation a breeze.
