Iturra Spinner 3 Bandsaw Tensioning Crank 189102

Spinner 3 Bandsaw Tensioning Crank


The Spinner 3 replaces the tension adjusting rod and knob on 14" bandsaws, and improves on stock tensioners in several ways. The most obvious improvement is ergonomic: rather than a tiny plastic knob, you'll be spinning a 5" cast-iron, chrome-plated handwheel like you'd expect on a larger machine. Functionally, the 3/8" dia. rod is thicker and less prone to flex than the smaller-diameter rods on some machines, and the acme threads withstand the force of tensioning blandsaw blades much more securely. The threads in the massive bearing-bronze nut are precise enough to nearly eliminate slop or blacklash. Best of all, installation is quick and tool-free. Retrofits most Delta/Rockwell, JET, Grizzly, Rigid and Craftsman 14" bandsaws.

  • Rod diameter is 3/8"
  • Overall rod length is 13"
  • Overall length of threads on rod is 4"
  • Acme threads are 12 per inch. Included bronze nut fits the threads.
  • Bronze nut is 11/16" x 11/16" x 19/32" high
  • Rod inserts into chrome handle 7/8" and secures with an included set screw.
  • One end of the rod is ground to a cone point.

Things to consider if you are unsure if the Spinner 3 will fit your bandsaw:

  1. Is the rod long enough so the installed chrome handwheel will clear the top of the upper wheel housing cover of your saw?
  2. Is the space where the nut for the tension rod resides big enough to house the bronze nut?
  3. Is the area where the tip of the tension rod rests on your saw (and carries the tension load) have a small indentation to accept the cone point shaped end of the rod or does it at least have enough area for the point of the rod to rest?
  4. Does the current tension spring on your saw have an inside dimension that will allow the 3/8" diameter rod to pass through the center of the tension spring?
