The fine art of fine tuning.
If your "Farley" rest dosen't feel as precise as you think it should, or it dosen't hold it's position replace the tension screw buttons with our tension screws. These replacement tension screws are fitted with a "Delrin" pad supported by a pair of Belleville washers. These replacement screws will give a much better feel to the action of the rest.
