Follow up to my last post. I routinely lubricate the key pins and bushings with Protek (part of my new 1.5 hour service call). The easiest and fastest way (when you can't or don't want to take the time to remove the keys and polish) is to pull the action (grand piano) and stand it up with the back rail resting on the key bed. With a hypo oiler put a few drops per pin on the front rail pin and let it run up into the bushing. For the sharps you have to sharpen your aim and do it "bombs away" style unless you have an extension applicator that will reach. With the action still standing up, use McLube (or your spray lube of choice) and spray the bottom of the front and back rail, the glides and the right side of the frame that contacts the return spring. Before you lay the action down spray the key bed under the front rail. Lay the action back down when you are done, slide it out slightly and reach in with the can of McLube and spray the tops of the glide bolt dowels, the key bed under the back rail, and the return spring. Slide the action back in a bit and put a few drops of Protek on top of each balance rail pin and let it run down. Use a piece of cut hammer felt to apply microfine teflon to the knuckles and spray the tops of the jacks with McLube. The whole procedure takes about 5-10 minutes. I think that in general nothing will make the action feel better faster than lubricating it. Most customers will immediately notice the difference. David Love
