Terry, there is one easy to miss factor in your logic. If you push the keys down with absolutely no side pressure you are correct. Pianists however have this nasty habit of pushing the key down at an angle. Sooo any friction gets increased by the amount of side pressure on the key. I remember Fern Henry making this point many years ago. (See how good my long term memory is?) She suggested at that time to spray the pins and bushings with an aerosol Teflon lube or mold release. I've bought over the years several cases of mold release from Aervoe in Gardnerville, Nevada. I've used it for knuckles, key pins, capstans and the whippen cloth. It's great for your table saw top too. I think It is just Teflon powder dispersed in freon that evaporates off in a few seconds leaving a thin film of Teflon. Don't leave home without it.
