    Re: Rhino ST6 CNC Lathe Restoration

    469010

    The Spindle motor is a Baldor 90VDC 1/2HP motor.

    Anyone have any suggestions for how to remove the old paint and rust?

    The original electronics used a DOS based PC. I intend to change all the electronics out for newer equipment. The Centroid Acorn and some Hybrid Steppers.

    Re: G0704 with 3 Phase Leeson Metric motor

    I just got back around to posting some videos about the conversion of the G0704 to Leeson motor. Here is the one about removing the stock motor.

    Centroid Acorn interview

    I recently interviewed Keith McCulloch and discussed the Centroid Acorn DIY CNC Controller on the CNC Router Tips podcast. I thought some of you may find the information helpful.

    Re: Setting up Tormach Touch Screen

    I never was able to get that monitor to work. I was able to get another one working. So I blame the monitor. Tormach swapped it out.

    Got the touchscreen but it does not work. I am getting a blue no signal screen. Never see if PP boots up or not. I swapped to another monitor and that works. Guess I will call Tormach Tuesday.

    They were metric bolts but I don't remember the size. Take one of the bolts from the mounting feet and try that. Then go to the hardware store to match it.
