    I have always disliked the spring that provides the tracking on the KMG

    I bought a 40 pound gas spring from McMaster-Carr and had to figure out how to mount it. I drilled and tapped the arm that the tracking wheel is mounted to.

    I decided to mount the bottom of the spring to the tool rest arm mount. I took a piece of 1 inch square and threw it on the lathe to face, drill and tap. I then welded it to the mount.

    After it cooled, I put it all together.

    It runs smoother and the tracking is excellent. I only wish I had done this sooner.

    It cost me $17 for the spring and about an hour of my time.

    Figured I would bump this with my newest modification.

    I wanted to make it a direct drive. There are a few ways to do it. I do not need a new motor, so I wasn't going to buy a new one that mounts on the shaft side. That also meant that I didn't have to make a mounting plate or take the grinder apart.

    I used a Lovejoy coupling.

    To get the shafts to line up I made a mounting plate for the motor. The plate also got the height of the shaft correct. I used some existing tapped holes to mount the plate.

    It runs much more quietly with less vibration. It also allowed me to move the VFD back. I did have to move the tooling arm storage.

    Thanks for looking.

    Maybe it is just me, but I am not seeing any of the images.
