TurinKeeper for the DF64 or DF83 The TurinKeeper for the DF64 or DF83 allows you to track your settings with ease! Had to laugh at the name, but this is an upgraded dial indicator for the Turin DF64 grinder. It also works with Solo and the other names this grinder has been given. This dial assists you with tracking setting changes. I had issues seeing the small line on the front of the grinder and tracking small increments. The TurinKeeper points to the lines on the adjustment ring and also has a small opening to display the numbers indicated on the dial. The Turin Keeper slips over the collar of the Turin grinder, and attaches using a set screw. A standard Phillips screwdriver secures the indicator in place. Turin grinder or any other parts not included. This listing is for (1) ring and (1) set screw. Made from high quality ABS plastic. Available is a variety of colors.
