A couple of questions...Are these low end machine heads? How long have you owned the guitar? Did the stiffness come about suddenly or over a period of time? Normally it's easiest to replace low end machines if they have a problem. On better quality machines what normally causes sudden stiffness (binding) is a cracked roller. Inspect the plastic on the roller giving you trouble and see if there isn't a crack in it. If there is you'll need to remove the machines and try to find a replacement roller. Some music stores have them and most luthiers. Be aware that they come in at least 2 different diameters and the end which connects to the gear has several configurations (square, splined, hexagonal, etc.) and the screws are not all the same size. Good luck, John Shelton
