Date: Sat, 2 Oct 2004 Terry, I've found the following to work rather well: While the flanges are still attached to the rail, center punch and drill for the appropriate flange screws. Then remove the flanges. I prefer to put some moisture (just a little) and heat to them. They'll pop off fairly well with a little coaxing with a chisel. Clean up the rail and add sandpaper strips w/appropriate holes punched. I like to attach the sandpaper with cold hide glue as it gives you a sufficient amount of time to get everything lined up and it doesn't leave lumps/bubbles in the sandpaper. (less traveling needed, but there will be some.) Most of these do not have "damper barrels", so I add them. a simple jig for the drill press will get that job done. Drill for a tight fit and press them in with a punch in the drill press after the holes have been drilled. Sure will make puttin' em in a lot easier. BTW, the thingee you are wondering about terminology-wise, is called the Top Flange.<G> I like to use the specs. from the olde Steinway manual. Without looking, I recall the Top Flange is 1-3 grams and the Lever is 3-5 grams. Hope that helps. Best Regards, Joe Garrett, R.P.T.
