How do I fix the fold knob on my Wolf loom?

On older Wolf looms, if you completely unscrew the fold knob, the metal T-nut that the knob screws into can slip down inside the castle far enough that you cannot put in the fold knob. The pictures here show a newer loom. With the fold knob removed, you can see that the hole in the metal T-nut is still accessible.

Installing fold knob


Part of the hole in the metal T-nut should be visible. You can insert the tip of a straightened paper clip in the hole, then pull the T-nut up to expose the hole. You can put something like a screwdriver under the T-nut to hold it up while you reattach the plastic T-nut slide, fold support bars, and fold knob. Be sure to put the front fold support bar next to the plastic T-nut slide, then the rear fold support bar.

If your loom is unfolded, you might need to pull on the fold support bars to get the holes to line up for the knob.

Note: Loosening both knobs all the way or removing them can cause the loom to collapse which could result in injury.

Replacing the Metal T-Nut

If you are unable to get the fold knob screwed into the metal T-nut, it's possible that the threads in the screw hole are stripped. You can order a replacement T-nut here.

To install a new T-nut, you will need to do the following:

  1. Remove the shafts—all four on a 4-shaft loom or the first four on an 8-shaft loom.
  2. Remove the metal channel on the inside of the castle.
  3. Take out the metal T-nut and replace it with a new T-nut.
  4. Replace the metal channel.
  5. Replace the shafts.
