You're right that the weights won't do anything for the hammer flanges, but after they are lubricated or alcohol/water shrunk (I wouldn't re pin except as a last resort) all the flange centers (hammer, jack and wip), the other weirdnesses become noticeable. What I've found on the old Wurlitzer consoles and spinets is big fan angles in the key doglegs, and key ratios leaving a lot of front weight on the keys. After the years of use, the key bushings wear and the wippen weight is no longer enough to lever the key back up out of the groove in that outside bushing (the inside ones last forever, because the balance rail pin hardly ever touches them). Your choices for restoring function are either rebushing, or backweighting, since you can't do much about the design layout. Reasonably, rebushing would be a better option because adding backweight will put more pressure on that outside bushing and accelerate bushing wear even more. Giving the owners of Wurlitzer consoles and spinets an explanation of the problems, and the options of replacing the piano, spending $$$$ on repinning, or $ on lubrication, and $$$$ on rebushing keys, or $$ on keyweights if necessary after lubrication, I have yet to find one that wanted anything other than the minimum expenditure to "make it work". Obviously, the back weighting isn't considered if the lubrication, shrinking, or whatever works well enough, and it's certainly not technically the best approach. It's a means of getting the customer playing again at minimal cost and they will probably get another fifteen years of use out of the piano playing on the mortise. They'll also comment on how "Easy" it is to play now. It's not an ideal fix, but it's expedient, relatively cheap, and a way out when you don't have a way around the design limitations anyway. I've put in maybe five sets in over twenty years, so it's not an habitual first choice. It's yet another one of those unfortunate choices between what's right, what's possible, and what's affordable. I hope that's a better explanation. Ron N
