    Universal Grinder Power Feed xy table power feed

    I finally got the time to put my power feed on my universal grinder. It will be used any time the x position needs to be changed. Manual feed from the opposite end is still useable but it considerably stiffer with the motor engaged. It only required 4 new pieces of aluminum to complete the project. It is now ready for power.

    Here is a link to the "Universal" Grinder which uses the xy table. Parts for the motor drive are listed there.

    Control Box For Universal Grinder Table Feed

    I have a few shots of the "portable" feed motor power supply. I will use this on the lathe feed screw(not done yet) and on the Universal Grinder power feed. The parts are the same as used on the Mini Mill power feed with the exception of the plastic box. The 15 vdc power supply brick is simply epoxied on to the box. The mill unit is mounted on the spindle housing in a more permanent position as I use it all the time. On the lathe and grinder I will not be using it all the time so I went for a portable method.

    Cheers, JR

    Nice clean build JR. A thought for the hand wheel/motor coupling issue. Perhaps if you cut your coupler in 2 and milled a couple of flats for a small plate and thumb screws you could uncouple the gear motor with a drop latch of some kind...of course you would have to align it again to recouple. Just thoughts...

    Thanks for sharing this great build. ~PJ

    I have seen a post of a motorized X table on a mill. They used a sliding socket to engage and disengage the motor, real simple.
    I'll have to see if I can the page again.

    Nicely done!
    I borrowed the idea from a u-tube video for a very nice sliding coupler and variable speed , two direction controller for my mill. Works great! Have a peek at his video and it may inspire you as well.


    Keep on building!

    Thanks Rick that was the video I was thinking about.

    It really is a great idea for engaging and disengaging the drive motor.

    Thanks for the tips guys. That manual clutch is the way to go.

    Cheers, JR
