This is a new addition to our assortment and will require you make your drive shaft 2" longer than the plans calls for. No other change will be required and this will give you 4 speeds instead of 3 speeds as we recommend in the No Weld Grinder Plans. Your choice.

You will need 2 of these to make this work. There is no work around for just one. Order 2 if you are going to use a 4 step pulley system.
Basically, you mount one to your motor, the other to the drive shaft. When the motor is stopped, you manually move the belt from one set of grooves to the next to get 4 different speeds. A poor man's multi-speed controller.

Great Options
I purchased two of these for my NWG build. I ended up using an old DC motor with variable to run the grinder, but added these to the build anyway. Now I have even more speed options. 4 grove pulleys are very hard to find so if you are considering a grinder build you need these. Great quality as well.
