Sprocket Wrench

[markfitz]

This tool was originally made to hold motorcycle countershaft sprockets from turning while removing/tightening the nut holding them to the shaft. I used a 16-inch piece of 1/2" steel tubing for the handle. I then welded a 16" piece of chain to the handle, 4" from one end. Dimensions are not critical, but you do want to have the chain running oriented toward the short end, as shown in the picture.

Hola Mark, gracias por el aporte, tomaré tu idea pero cambiando la cadena por un fleje metálico para sujetar la piedra esmeril ya que las roscas de ambas partes giran en igual sentido, si con este implemento lograré sujetar una de ellas y ajustar la otra con mas facilidad, desde ya gracias y estoy a tus ordenes para lo que pueda ayudar, hasta pronto.

Hi. Rather than using a metal strap, you will probably get a better grip with a normal strap wrench. I suppose that you could fix a D-ring to the handle to lock the strap. (Think motorcycle helmet.). - Mark
