Yesterday my Haas Remote Jog Handle's small knob broke off. In taking it apart it was discovered that the plastic shaft that the knob attaches to fractured right at the knob. It looks like the interface between the knob and the shaft is a weak design. So a few hours later I had a repair and had it back in service. The design was changed a bit where it attaches to the knob. A long 6-32 screw was used to clamp the knob to the new part. A small delrin hub was made for the head of the screw. Here are the images in case anyone else has a similar issue. The jog handle cost 2K and I doubt parts are available. Watch out for the two small springs and cylinders that make the click as they are easy to launch. Watch the alignment of the gears where they mate with the electrical parts.
