Rip the cloth, don't cut it; cut one end to a point for = insertion into the hole. Apply a very scant amount of hide glue mostly at = the joint area, this hopefully will keep it from being pushed out = sometime in the future with a curved reamer. Insert the cloth from the = underside of the rail so the glue is pulled in from underneath.  I usually have = the joint positioned to the rear, you do not want it on either = side. Cut the cloth slightly proud of the rail, about the thickness of = the banded back edge of the razor blade. Once the rail is complete, Press = the bushings with an awl from both sides. When dry, the bushings are = ironed with a caul made out of a bridge pin and 1/4" brass rod to fit into = the Key Bushing Iron. Finish with a pipe cleaner and Teflon powder. <X-SIGSEP> </X-SIGSEP>Regards, Jon Page, piano technician Harwich = Port, Cape Cod, Mass. <A href="mailto:jonpage@comcast.net" eudora="autourl">mailto:jonpage@comcast.net</A> [Paul Chick (Earthlink)] I like to spray a coat of shellac on the rails, = aiming at the holes.  When dry, fit the cloth as Jon mentions.  Intsall the bushing cloth as described but use no = glue.  Insert a # 7 bridge pin into the hole then put a drop = of alcohol on the bushing cloth (the 70% stuff from the drug = store).  Allow to air dry or use a hair dryer to speed the work.  The alcohol = softens the shellac enough to "glue" the felt into the rail.  Add teflon powder.
